Rapidly rising heat will cut maize harvests

Soon the corn could roast on the cob long before the maize harvests are due. That could be far sooner than anyone expects.

LONDON, 3 April, 2019 − European scientists have bad news for the world’s farmers: within a decade, maize harvests will suffer as global temperatures will have reached a level that will turn the once-in-a-decade extremes of heat and drought into the new normal.

That will mean that the worst production losses ever felt by the maize farmers will happen with increasing frequency, if global planetary temperatures reach 1.5°C above the long-term average for almost all human history.

The world is already 1°C hotter on average than it was before the Industrial Revolution and its increasing dependence on fossil fuels to power the global economies.

And if the temperature reaches 2°C, researchers warn, farmlands where maize once flourished will be hit by heat and drought events never before experienced. The big agribusiness giants will be hurt – and so will the small subsistence farmers who depend on their crop to keep their families alive.

“At the 2°C warning level . . . our projections suggest that global maize production will suffer from unprecedented losses”

Already the warming in the last few decades has begun to hit yields: the scientists reckon that maize yield within the 28 European member states is 290,000 tonnes a year lower than it would have been without global warming.

Significantly, 195 nations met in Paris in 2015 to agree to co-operate to keep average global warming down to if possible “well below” 2°C by 2100. Their target was a rise of no more than 1.5°C.

At the present rate of action – to switch to solar and wind power, to restore the world’s forests – the planet is on course to warm by 3°C by the close of the century.

But a new study by the European Union’s Joint Research Centre in Ispra, Italy, published in the journal Earth’s Future, is not worried about the average, but about the extremes that, over the course of a year, make up that average, and drive up the loss of one particular crop: maize.

Vulnerabilities

Maize is now the world’s biggest single crop: the US is the most important producer but the EU ranks fourth in the world, producing an average of 65 million tonnes a year for food and cattle fodder. This warm climate crop is at certain points in its growing season vulnerable to heat stress and to drought. And heat stress seems increasingly  certain.

Researchers have warned, repeatedly, that higher average planetary or regional temperatures will mean increasingly intense, frequent, prolonged and potentially dangerous extremes of heat. And those areas already vulnerable to drought are likely to see much more of it, while other regions will become more at risk of catastrophic flood.

Agricultural scientists have already confirmed that untimely spells of heat and drought have started to slash cereal yields as measured across whole regions, or per field.

Hunger warning

And although the US has increased production, this too will be vulnerable to further warming. The World Meteorological Organisation has just warned of an already warmer, hungrier world.

The European researchers report that their analysis of past and future maize production surveys a range of outcomes: in one of these, the worst could start to happen as early as 2020. They suggest greater efforts to meet the goals set in Paris but even with those, farmers and agriculture ministries will need to find ways to adapt.

Their report ends bluntly. “We found that global warming will substantially increase the risk of maize production losses in most world regions, including the United States. The climatic events affecting historical global maize production once every 10 years will become normal at the 1.5°C global warming level, which is reached in the 2020s in most of the analysed climate model simulations,” they write.

Green New Deal aims for triple payback

Support is growing for a plan to tackle climate change, our economic crisis and deepening social divisions together − the Green New Deal.

LONDON, 18 March, 2019 − If you haven’t yet heard of the Green New Deal, chances are that you soon will. To its growing band of supporters, it looks like an idea whose time has come.

Just suppose we could see a  way to transform the global economy, society and even the environment so that they met real needs, and promised to go on doing so far into the future. Well, we can. And it’s growing simpler all the time, futurologists say.

The bad news? Inertia and resistance. Too few of us think we really need a transformation. Too many are actively trying to prevent one. No change there then − except that the balance may be starting to shift, thanks largely to science and money − and ordinary people who are refusing to go on as we are.

Supporters of the Green New Deal say we don’t have to look very far ahead for results − no further than about mid-century.

By then, some of them told The New Yorker magazine, much of the world should be able to achieve the goal of zero carbon emissions, a goal for which they say the world already has about 90-95% of the technology it needs.

Technological gallop

One problem often raised is the need to store the power produced by wind and solar power, which may be inconveniently unavailable just when it’s needed. But even here there are hopeful signs that the galloping pace of technological advance may soon have an answer in the form of greatly improved batteries.

The Deal’s supporters are not the first to claim we’re most of the way towards a carbon-free future in 30 years, and possibly well before that. But this Deal, itself a reminder of US President Franklin D Roosevelt’s 1933 New Deal, explores more ambitious territory still, with the prospect of also ensuring a living wage job for everyone who wants one and reducing racial, regional and gender-based inequalities in income and wealth.

To make any headway the new Deal will need strong political backing. Here it’s had a stroke of luck, being identified with the arrival in Washington DC of the politician Alexandria Ocasio-Cortez, the youngest woman ever elected to the US Congress.

There are signs across the Atlantic of mounting involvement in the ideas spelt out in the Green New Deal, incorporating lessons learned from France, for instance, and the experience of Germany.

“Any Green New Deal worthy of the name creates millions of ‘green collar’ jobs … The opportunities are immediate, needed and everywhere”

In Britain a rising star of the parliamentary opposition, Clive Lewis, the shadow sustainable economy minister, told a recent meeting: “The green economy will simply be ‘the economy’ under the next Labour government”.

The British economist Ann Pettifor, a fellow of the New Economics Foundation, describes the Green New Deal as “incredibly ambitious . . . a huge advance for green campaigners and, hopefully, for our threatened species.”  Pettifor was co-author of the original Green New Deal Report, published in the UK in 2008, which in many ways prefigured the present US initiative.

Her fellow co-author was Andrew Simms, now co-ordinator of the Rapid Transition Alliance (RTA), an enthusiastic backer of Ocasio-Cortez’ vision.

The RTA says: “Like the UK proposal, [the Deal] seeks to tackle the climate and economic crisis simultaneously and looks at job creation, decarbonising electricity, renovating buildings for energy efficiency and much more.

Affordable

“A Green New Deal today would cost no more than [Roosevelt’s] New Deal, less than the 2008 bailouts, and see off the worst effects of the climate crisis.”

Simms told the Climate News Network: “What does it actually look like to start transforming our economies to prevent climate breakdown and meet the internationally agreed climate targets?

“Practically it looks like a Green New Deal − a programme that meets our economic, social and environmental needs at the same time − a ‘win, win, win’ package of measures.

“Any Green New Deal worthy of the name creates millions of ‘green collar’ jobs by building the low-carbon infrastructures which respect environmental limits and are vital to modern economies − renewable energy, zero carbon homes, efficient and clean mass transport systems delivered by switching investments from old, dirty ways of doing things and with innovative financial mechanisms. The opportunities are immediate, needed and everywhere.”

Obstacles remain

Perhaps an idea which puts the environment, the economy and social justice together can hope to mobilise mass support in a way the three distinct groups have so far not managed to achieve − especially when it exploits the potential of new technology and falling costs. But there’s still political inertia to reckon with, and financial self-interest.

Even there, change may be afoot. A British group of scientists, activists and one former archbishop of Canterbury, ExtinctionRebellion, has been staging audacious public protests in the UK for four months now, and started a spring uprising on 16 March, giving no sign yet of succumbing to inertia.

And resistance to the very idea that the world needs an energy transformation? A brief online search for the way parts of the fossil fuel industry continue to challenge and decry climate science suggests change could be coming there too. One example from the US site Inside Climate News shows the deniers are facing challenges of their own.

Change on the scale envisaged by the Green New Deal is certainly demanding, but it will be far less so than refusing to change. − Climate News Network

Paris climate pledge would help world fishing

Honouring the Paris climate pledge would provide a fair catch for the world’s fishing fleets. Warm up the oceans, though, and everyone loses.

LONDON, 12 March, 2019 – Canadian scientists have worked out the way to make the most of the world’s fish stocks: by honouring the Paris climate pledge.

Seagoing nations could raise revenues for their fishing fleets, put more seafood on the table and protect the most valuable commercial fish stocks simply by doing what they had promised in 2015 to do anyway.

The key is the historic agreement reached then in Paris by 195 nations, to take steps to limit average global warming to “well below” a total of 2°C above the long-term average for most of human history, and to do this by 2100.

In the last century or so the global temperature has already risen by around 1°C, as a consequence of ever-increasing combustion of fossil fuels that emit greenhouse gases into the atmosphere.

“The largest gains will occur in developing country waters … which are at the greatest risk due to warming temperatures”

But although the world agreed its ideal target, the action so far leaves it on course for a potentially catastrophic rise of 3.5°C by the end of the century.

“Achieving the Agreement’s target could increase global fisheries revenues by $4.6 billion annually, seafood workers’ income by $3.7 bn and reduce household seafood expenditures by $5.4 bn,” said Rashid Sumaila, of the University of British Columbia’s Institute for Oceans and Fisheries.

“The largest gains will occur in developing country waters, such as Kiribati, the Maldives and Indonesia, which are at the greatest risk due to warming temperatures and rely the most on fish for food security, incomes and employment.”

What the researchers did – they explain their approach in the journal Science Advances – was to match what the computer forecasts said the Paris target would deliver, with what might happen if the world went on burning oil, coal and gas under the notorious business-as-usual scenario.

Impacts on ecosystems

They looked at the impact of less or more warming on 381 marine species, including the 10 that generate the most money, and they included ecosystem consequences as well as the economic payoff promised by the Paris target.

Their conclusion is that three-fourths of maritime countries would benefit, with the largest gains to be made by the developing nations.

Under the Paris scenario, the total mass of the fish species that generate the highest revenues would increase globally by 6.5%, with an 8.4% increase in the waters of developing countries. Overall, developed countries would see a marginal fall of 0.4%.

The Paris option would see an additional 3.3 million tonnes landed sustainably every year, compared with the business-as-usual scenario.

Conservation also needed

The British Columbia scientists are not the first to make the case for Paris in terms of fishery revenues: US and Japanese scientists looked at the same problem last year and concluded that the Paris option – matched by careful conservation approaches – could yield more fish for the hungry, and more revenues for the fishermen, if the ocean temperatures were kept from rising too dangerously.

But all the signals so far are ominous. A warmer world means a stormier one and greater danger for fishing fleets. More carbon dioxide in the atmosphere means ever more acidic seas, which seems to affect fish behaviour and threaten marine habitats such as coral reefs and kelp forests.

The same rise in carbon dioxide will warm the oceans and drive fish to migrate. Overall, humans have already left the seas diminished, and worse could be on the way. Fishing and seafood support an estimated 260 million full-time and part-time jobs worldwide.

Many to benefit

The Science Advances study is a reminder that while change is inexorable, the worst need not be inevitable. All continents except Europe would benefit from implementation of the Paris Agreement.

But as fish move towards the poles, countries in northern Europe might benefit from greater choice in their waters, and losses in the overall catch might be buffered by hjgher prices for those fish actually landed.

Russia could see catches reduced by as much as 25% under the 1.5°C target rather than the 3.5°C forecast. “However a projected 19% increase in fish prices, known as the price effect, should result in a negligible loss of less than 2% in fisheries revenues in Russia,” said William Cheung, one of the co-authors, of the University of British Columbia.

“Conversely, for the US fishing revenues are expected to decrease by 8% due to price effects but will be offset by a 21% increase in catch potential.” – Climate News Network

For offshore wind turbines size matters

As turbines grow in size and costs tumble, offshore wind turbines, both floating and fixed to the seabed, have vast potential.

LONDON, 7 March, 2019 − Offshore wind power is set to become one of the world’s largest electricity producers in the next decade as costs fall and turbines grow in size.

Up till now turbines standing on the seabed near to the coast in Europe have been seen as the most promising technology for offshore wind farms. But the success of floating machines that can be deployed in deeper water has meant many more coastal communities can benefit. Japan and the US are among the countries with the greatest potential.

The speed with which the industry has grown in the last decade has defied all expectations. Large turbines used to have a two to three megawatt output, but now the standard size is 7.5 megawatts and turbines capable of generating up to 10 megawatts are in the pipeline.

As a result the output of one offshore turbine is thirty times greater than with the first ones deployed in 1991 − and the cost has fallen to half that of new nuclear power.

This, coupled with experience showing that the wind blows more steadily out to sea and produces far more consistent power than turbines on land, has led many more countries to see offshore wind as a major potential source of renewable energy. The turbines have shown themselves to be robust even in extreme storm conditions.

“Previous estimates of the growth of renewables, at least wind and solar power, have always been underestimates”

Production has just begun from the world’s largest offshore wind farm in the North Sea, where construction started only in January 2018 and which began feeding power ashore in England 13 months later. The project is enormous, all four phases covering nearly 2,000 square miles, and will produce up to 6 GW of power, the same as five large nuclear power stations.

Apart from the sheer size, the plan is to have the whole development completed by 2025, before the partly-constructed Hinkley Point C nuclear power station in the West of England will start up, and providing return on capital for the investors years before its nuclear rivals.

While the market for turbines fixed to the seabed is expected to continue to grow very fast, it is floating turbines that will be the next big player. These are again huge machines, taking advantage of the steadier
winds out to sea, and not needing expensive seabed foundations.

It took 15 years for the Norwegian state oil company Statoil, now rebranded as Equinor to emphasise its partial move to renewables, to develop the first offshore wind farm 15 miles of the coast of Aberdeen in Scotland.

Outrunning expectations

There are five turbines with blades 175 metres long and a counterweight extending 78 metres below the surface, which is chained to the seabed. The turbines started feeding into the grid in October 2017 and output was soon exceeding expectations.

The fact that it was Statoil that designed and developed the floating turbines is significant. The offshore wind industry uses many of the skills developed by offshore gas and oil ventures and provides an investment opportunity for oil majors under pressure to diversify and show they have green credentials.

A report, Wind Power to Spare, produced last year by a research and campaigning group, Environment America, showed that there was enough potential wind power just off the US east coast to provide more electricity than was currently used in the region’s maritime states – plus enough for powering electric cars and for providing heating for the entire population of the eastern coastal states in the future.

Since the report was published developers, looking at the success of Europe in exploiting this resource, have shown an escalation of interest. The same is true of Japan, where the nuclear industry remains in deep trouble as a result of the Fukushima accident in 2011, with many of its reactors not expected to restart.

Potential ignored

Back in Europe, where offshore wind was first developed, manufacturers are eyeing up potential new markets both in the North Sea and elsewhere. France for example has no offshore wind farms but could deploy hundreds of floating turbines.

Research suggests that water depths in the North Sea are ideal for floating turbines. If half the area available could be covered in turbines they would make enough electricity to power the whole EU four times over.

That prediction is made by Equinor. It also estimates in the same report that by 2030 Japan could have 3.5 gigawatts of floating wind power, France 2.9 GW and the US 2 GW, with a further 1.9 GW in the UK and Ireland.

This would make a significant contribution to reducing the world’s burning of fossil fuels, particularly since previous estimates of the growth of renewables, at least wind and solar power, have always been underestimates. − Climate News Network

It took 15 years for the Norwegian state oil company Statoil, now rebranded as Equinor to emphasise its partial move to renewables, to develop the first offshore wind farm 15 miles of the coast of Aberdeen in Scotland.

Outrunning expectations

There are five turbines with blades 175 metres long and a counterweight extending 78 metres below the surface, which is chained to the seabed. The turbines started feeding into the grid in October 2017 and output was soon exceeding expectations.

The fact that it was Statoil that designed and developed the floating turbines is significant. The offshore wind industry uses many of the skills developed by offshore gas and oil ventures and provides an investment opportunity for oil majors under pressure to diversify and show they have green credentials.

A report, Wind Power to Spare, produced last year by a research and campaigning group, Environment America, showed that there was enough potential wind power just off the US east coast to provide more electricity than was currently used in the region’s maritime states – plus enough for powering electric cars and for providing heating for the entire population of the eastern coastal states in the future.

Since the report was published developers, looking at the success of Europe in exploiting this resource, have shown an escalation of interest. The same is true of Japan, where the nuclear industry remains in deep trouble as a result of the Fukushima accident in 2011, with many of its reactors not expected to restart.

Potential ignored

Back in Europe, where offshore wind was first developed, manufacturers are eyeing up potential new markets both in the North Sea and elsewhere. France for example has no offshore wind farms but could deploy hundreds of floating turbines.

Research suggests that water depths in the North Sea are ideal for floating turbines. If half the area available could be covered in turbines they would make enough electricity to power the whole EU four times over.

That prediction is made by Equinor. It also estimates in the same report that by 2030 Japan could have 3.5 gigawatts of floating wind power, France 2.9 GW and the US 2 GW, with a further 1.9 GW in the UK and Ireland.

This would make a significant contribution to reducing the world’s burning of fossil fuels, particularly since previous estimates of the growth of renewables, at least wind and solar power, have always been underestimates. − Climate News Network

Southward shift faces US climate by 2100

Climate change means a big shift for city dwellers worldwide. Americans can look ahead to very different cities as the US climate heads south.

LONDON, 21 February, 2019 − If the world continues to burn ever-increasing levels of fossil fuels, then life will change predictably for millions of American city dwellers as the US climate heats up. They will find conditions that will make it seem as if they have shifted south by as much as 850 kilometres.

New Yorkers will find themselves experiencing temperature and rainfall conditions appropriate to a small town in Arkansas. People from Los Angeles will discover what it is like to live, right now, on the southernmost tip of the Baja peninsula, Mexico. People in Abilene, Texas will find that it is as if they had crossed their own frontier, deep into Salinas, Mexico.

The lawmakers in Washington will have consigned themselves to conditions appropriate to Greenwood, Mississippi. Columbus, Ohio, will enjoy the climate of Jonesboro, Arkansas. Folk of Anchorage, Alaska, will find out what it feels like to live on Vancouver Sound. People of Vancouver, meanwhile, will feel as if they had crossed the border into Seattle, Washington.

This exercise in precision forecasting, published in the journal Nature Communications, has been tested in computer simulations for approximately 250 million US and Canadian citizens in 540 cities.

That is, around three quarters of all the population of the United States, and half of all Canadians, can now check the rainfall and temperature changes they can expect in one human lifetime, somewhere between 2070 and 2099.

“It is my hope that people have that ‘wow’ moment, and it sinks in for the first time the scale of the changes we’re expecting in a single generation”

There are a number of possible climate shifts, depending on whether or not 195 nations fulfil the vow made in Paris in 2015 to work to keep the average rise in global temperatures to “well below” 2°C by 2100.

In fact, President Trump has announced a US withdrawal from the Paris Agreement, and many of the nations that stand by the promise have yet to commit to convincing action.

So researchers continue to incorporate the notorious “business-as-usual” scenario in their simulations. So far, these have already predicted a sweltering future for many US cities, with devastating consequences for electrical power supplies and ever more destructive superstorms, megadroughts and floods, with huge economic costs for American government, business and taxpayers.

And, other researchers have found, climate change may already be at work: there is evidence that the division between the more arid American West and the more fertile eastern states has begun to shift significantly.

Long trip south

So the latest research could prove another way of bringing home to US citizens some of the challenges ahead.

“Under current high emissions, the average urban dweller is going to have to drive more than 500 miles (850 kms) to the south to find a climate like that expected in their home city by 2080. Not only is climate changing, but climates that don’t presently exist in North America will be prevalent in a lot of urban areas,” said Matt Fitzpatrick, of the University of Maryland, who led the study.

“Within the lifetime of children living today, the climate of many regions is projected to change from the familiar to conditions unlike those experienced in the same place by their parents, grandparents or perhaps any generation in millennia,” he said.

Coffee harvests face risk from rising heat

Global coffee harvests, which provide the drink of choice for millions and the livelihoods of many more, are in peril, not least from rising temperatures.

LONDON, 28 January, 2019 – Coffee drinkers, be warned. A combination of factors – including climate change – is threatening supplies of the beans on which the coffee harvests depend.

Latest analysis by a team of scientists at the Royal Botanic Gardens at Kew in London found that more than 60% of over 120 coffee species known across Africa, Asia and Australasia are threatened with extinction.

For many people, coffee is their favourite tipple. In the UK alone, more than 80 million cups of coffee are drunk every day. The experts at Kew say a total of 100 million people around the world depend on coffee for their livelihoods.

Climate change, together with fungal diseases and the impact of land clearances and deforestation, are all having negative impacts on coffee plants.

Coffee plants are fragile and often acutely sensitive to temperature changes, particularly those belonging to the Arabica species (Coffea arabica), the source of the world’s most popular coffee variety.

“Climate change will have a damaging impact on commercial coffee production worldwide”

The Coffee Research Institute says Arabica plants need year-round temperatures of between 15°C and 24°C in order to maintain high production levels and good quality.

Wild coffee plants play an essential role in building up more robust plants for cultivation; cross-bred with plantation plants, they provide the genetic resources to help withstand pests and diseases. They also encourage resilience to changes in climate and improve the flavour and quality of the coffee beans.

The Kew scientists, together with colleagues in Ethiopia,
the biggest producer of Arabica coffee in Africa, used climate change models and temperature projections to gauge the future health and survival rates of wild Arabica plants.

The results of the analysis, the first ever comprehensive survey linking climate change with Arabica coffee production, will have coffee drinkers crying into their cups.

Wide extinction threat

Dr Justin Moat, who headed up the Kew study, says more than 60% of wild Arabica plants are threatened with extinction.

“The worst case scenario, as drawn from our analyses, is that wild Arabica could be extinct by 2080.

“This should alert decision makers to the fragility of the species.”

The highlands of Ethiopia and of South Sudan are the natural home of Arabica coffee. Researchers found that deforestation over the past 70 years plus more recent changes in climate could result in wild Arabica becoming extinct in South Sudan within the next two years.

“The climate sensitivity of Arabica is confirmed, supporting the widely reported assumption that climate change will have a damaging impact on commercial coffee production worldwide”, says Dr Moat.

Pay growers more

In coffee-growing areas around the world, including Ethiopia and Brazil, temperatures have been rising while amounts of rainfall have been decreasing.

The Kew study says that while bumper coffee harvests over the last two years have led to generally low prices, this pattern is unlikely to continue as crop yields decline and demand grows.

The study says coffee growers, mostly smallholders, should be paid more for their produce in order not only to improve living standards but to encourage more sustainable and innovative cultivation methods. The Yayu Project in Ethiopia is seen as a model for this form of development.

There should also be more research into wild coffee species and investment in building up collections and seed banks. – Climate News Network

Battery boom aids climate change battle

The fastest-expanding industrial sector on the planet is now electricity storage − a battery boom which heralds an end to the need for fossil fuels.

LONDON, 18 January, 2019 − Billions of dollars are being invested worldwide in the developing battery boom, involving research into storage techniques to use the growing surpluses of cheap renewable energy now becoming available.

Recent developments in batteries are set to sweep aside the old arguments about renewables being intermittent, dismissing any need to continue building nuclear power plants and burning fossil fuels to act as a back-up when the wind does not blow, or the sun does not shine.

Batteries as large as the average family house and controlled by digital technology are being positioned across electricity networks. They are being charged when electricity is in surplus and therefore cheap, and the power they store is resold to the grid at a higher price during peak periods.

According to Bloomberg, around US$600 billion will be invested in large-scale batteries over the next 20 years to provide back-up to the grid and power for the expected boom in electric cars.

The cost of batteries is also expected to fall by 50% in the next decade, following the same pattern as the drop in cost of solar panels.

“The generally-held belief that there was no way to store electricity has been disproved. The battery boom means it is now just a question of finding the easiest and most economic way of doing it”

It is already financially viable for individual businesses to install batteries to buy electricity when it is cheap, so as to use it during peak periods. Two recent examples are the English premier league club Arsenal FC and a hotel in Edinburgh, the Scottish capital.

For Arsenal it makes sense to have a giant battery under its London stadium to store cheap power for use when its floodlights are needed during matches which are usually played when electricity prices are at their peak.

In Edinburgh, where there is often a surplus of wind power at night, the batteries provide cheap power for the 200-bedroom Premier Inn hotel in the morning and evening rush. In both cases the capital cost of the batteries is soon repaid in lower power costs.

Currently most large batteries are made of lithium, a relatively scarce and expensive mineral. Large investments are being made to find a way of making lithium batteries cheaper and more efficient, and the search is on for less expensive materials that can also be used to store electricity in battery form.

In Belgium, ironically on the site of a former coalmine, five large experimental batteries have been installed near Brussels to test the best technologies.

New possibilities

One of the latest advances is to use another rare metal, vanadium. Vanadium flow batteries are large static batteries that last for decades and can be charged and discharged completely thousands of times. They are not portable, but last for years without deterioration and are increasingly being deployed by national grids to boost supply during peak demand. A Canadian company, CellCube, has just sold a large battery plant to France.

This has been hailed as one of the most promising technologies in energy storage, but there are many other possibilities under development including high-energy magnesium batteries and lithium-air batteries, which are an advance on the current lithium-ion versions used in electric cars and for grid storage.

There are also new types of chemical batteries under trial as large-scale static installations which allow the grid to pump out more power at peak times.

The key battle for all these technologies is beating rivals on price. This means not just other battery types, but other options under development for storing energy. Surplus energy from renewables is also being used to produce hydrogen, while the surplus from solar power is often stored as heat.

In the first few years of this century the generally-held belief that there was no way to store electricity has been disproved. The battery boom means it is now just a question of finding the easiest and most economic way of doing it, and in doing so making a giant step towards a carbon-free future. − Climate News Network

VW says climate drives its electric spurt

Reputation and public confidence in your products are vital for global corporations, especially for one of the world’s biggest carmakers – hence VW’s electric spurt.

LONDON, 10 December, 2018 – As part of what it says is its commitment to tackling climate change, VW, the German auto giant, is embarking on an electric spurt, pressing ahead with plans aimed at producing more than a million electric cars a year by 2025.

In the vanguard of VW’s push into electric vehicles is the company’s plant at Zwickau, in the east of Germany, where an entire factory that once produced petrol and diesel car models is being converted to solely manufacturing electrically powered vehicles.

VW says that by the end of 2019 mass production of the ID, its new electric model, will begin at Zwickau; the aim is to eventually manufacture up to 330,000 electric models a year at the plant.

“With our electric cars we want to make a substantial contribution to climate protection”, says Thomas Ulbrich, head of the company’s electric car division.

“The global automotive industry is experiencing a process of fundamental structural change.

Affordable and popular

“Efficient, modern production facilities will be the key. In one year, this plant will become the starting point for our global electric offensive.”

Ulbrich says the aim is to take electric cars out of their niche and produce cars that will be affordable to millions – similar to the way the VW Beetle became popular around the globe.

VW says it’s investing about €1.2 billion in altering production facilities at Zwickau, where more than 7,500 people are employed. The company is also creating electric car plants elsewhere, including two in China – one near Shanghai and the other at Foshan in the south of the country.

Several other major car manufacturers have announced similar plans to ramp up electric vehicle production.

VW, by some measures the world’s biggest carmaker, has been struggling to repair its image after the company was forced in 2015 to admit it had sold nearly 600,000 cars in the US which had been fitted with special devices designed to circumvent emissions regulations and falsify exhaust gas tests.

“In one year, this plant will become the starting point for our global electric offensive”

The gases – nitric oxide and nitrogen dioxide – not only contribute to global warming but create pollution as well and can lead to health problems.

VW admitted that its engineers had designed a software system for its cars sold in the US which switched emissions controls on when vehicles were being tested and off during normal driving.

A number of other car producers, including the Japanese/French conglomerate Mitsubishi, have admitted falsifying various data relating to vehicle performance.

In the latest twist in the VW scandal, US prosecutors have alleged that what they describe as an “appalling fraud” was authorised by those at the very top of the company, with a former CEO involved.

To date, it’s estimated VW has paid out approximately US$25 bn in damages in relation to the emissions case. Court actions are ongoing with investors in VW who claim to have lost money over the scandal also suing the company. – Climate News Network

Hotter climate will cost Europe dear

Unrestrained global warming and a hotter climate will cost Europe dear in lives lost and economies squeezed. Even if it’s limited, there’ll be a price to pay.

LONDON, 23 November, 2018 – The continent must brace itself for the big heat: a hotter climate will cost Europe dear if average global temperatures soar by 3°C near the end of the century, when heat extremes could claim an additional 132,000 deaths a year.

Labour productivity in some southern European countries could fall by 10 to 15%. As sea levels rise, there could be a five-fold increase in coastal flood damage, to affect more than 2 million people and wreak economic tolls of €60 billion (US$68 bn) a year.

As extremes of rainfall increase, swollen rivers could expose three times as many people to inland flooding, and the damage from river floods could rise from €5.3m a year to €17.5m.

If, on the other hand, the world keeps the promise it made to itself in Paris in 2015, and contains global warming to 2°C or less by the century’s end, coastal flooding – which already affects 100,000 people and costs €1.25 bn a year – will affect only an estimated 436,000 and total €6 bn a year in annual damage.

Grim appraisal

But right now the world is on course to tip 3°C by the century’s end, and a new study by the European Commission’s joint research centre has made a sombre assessment of the likely costs.

There will be significant shifts in the times at which seeds sprout, flowers bloom and crops ripen, with big changes in soil water: this is going to affect agricultural productivity. Europe’s arid climate zone is expected to double in area.

Demand for energy to heat homes and offices is likely to fall, but any gains will be wiped out by a rapid rise in energy demand to cool cities and towns. Northern Europe can expect to get wetter, but some parts of southern Europe will, increasingly, face drought and water shortages.

Some of the forecasts are not new: researchers have repeatedly examined the impact of climate change on European harvests, and of sea level rise, for instance, on European coastal cities.

Terse summary

The latest report, labelled with the acronym Peseta III, presents a wider picture of change. It has been four years in the making, and is the product of consultation with experts in economics, biology, physics and engineering: its opening abstract says it all in three pithy sentences.

“The study assesses how climate change could affect Europe in eleven impact areas. Under a high warming scenario, several climate impacts show a clear geographical north-south divide. Most of the welfare losses, assessed for six impact areas, would be greatly reduced under a 2°C scenario.”

It attempts to put a crude measurement on the consumer cost to Europe’s economic welfare of various levels of possible climate change, and the headline figure is that 3°C warming could impose losses on the European Union nations of 1.9% of gross domestic product, or €240bn a year.

But this is an understatement “because key climate impacts cannot be quantified,” the researchers say. And once again, losses would be considerably lower if warming was contained to within 2°C.

Some winners

Under a lower warming regime, there could even be some benefits: Eastern Europe in particular could expect to see measurably higher agricultural yields, especially of wheat and maize.

In southern Europe, which will be both drier and warmer, yields are expected to decline. Irrigation may not be the answer: the harvest from irrigated fields is likely to start showing a decline by the mid-2030s.

By 2050, crop prices are likely to be depressed by the impacts of climate change. In effect, farmers could expect lower output, and on top of that, lower incomes per unit of output.

And these calculations do not include the direct impact of weather extremes – the heatwaves that shrivel seedlings, the hailstorms and high winds that damage blossom and so on – that are likely to be amplified by overall global warming.

“Under a high warming scenario, several climate impacts show a clear geographical north-south divide. Most of the welfare losses … would be greatly reduced under a 2°C scenario”

Transport, too, will be at the mercy of ever more intense and more frequent extremes of weather. By the century’s end, 200 airports and 850 seaports – large and small – could be affected by flooding from either rising sea levels or heavier downpours.

And the Mediterranean climate zone – with its unique mix of habitat, ground cover, biodiversity and crops – would become increasingly vulnerable to droughts, fires, pests and invasive alien species.

Labour productivity will fall, especially in the south, and in some places employers might have to plan to shift some work to the cooler night, with the additional costs of chronic fatigue, anxiety and depression associated with night work.

At 3°C, heat extremes could lead to additional deaths per year up to 132,000. But even at 2°C this figure could soar to 58,000 extra deaths per year. – Climate News Network

As extremes of rainfall increase, swollen rivers could expose three times as many people to inland flooding, and the damage from river floods could rise from €5.3m a year to €17.5m.

If, on the other hand, the world keeps the promise it made to itself in Paris in 2015, and contains global warming to 2°C or less by the century’s end, coastal flooding – which already affects 100,000 people and costs €1.25 bn a year – will affect only an estimated 436,000 and total €6 bn a year in annual damage.

Grim appraisal

But right now the world is on course to tip 3°C by the century’s end, and a new study by the European Commission’s joint research centre has made a sombre assessment of the likely costs.

There will be significant shifts in the times at which seeds sprout, flowers bloom and crops ripen, with big changes in soil water: this is going to affect agricultural productivity. Europe’s arid climate zone is expected to double in area.

Demand for energy to heat homes and offices is likely to fall, but any gains will be wiped out by a rapid rise in energy demand to cool cities and towns. Northern Europe can expect to get wetter, but some parts of southern Europe will, increasingly, face drought and water shortages.

Some of the forecasts are not new: researchers have repeatedly examined the impact of climate change on European harvests, and of sea level rise, for instance, on European coastal cities.

Terse summary

The latest report, labelled with the acronym Peseta III, presents a wider picture of change. It has been four years in the making, and is the product of consultation with experts in economics, biology, physics and engineering: its opening abstract says it all in three pithy sentences.

“The study assesses how climate change could affect Europe in eleven impact areas. Under a high warming scenario, several climate impacts show a clear geographical north-south divide. Most of the welfare losses, assessed for six impact areas, would be greatly reduced under a 2°C scenario.”

It attempts to put a crude measurement on the consumer cost to Europe’s economic welfare of various levels of possible climate change, and the headline figure is that 3°C warming could impose losses on the European Union nations of 1.9% of gross domestic product, or €240bn a year.

But this is an understatement “because key climate impacts cannot be quantified,” the researchers say. And once again, losses would be considerably lower if warming was contained to within 2°C.

Some winners

Under a lower warming regime, there could even be some benefits: Eastern Europe in particular could expect to see measurably higher agricultural yields, especially of wheat and maize.

In southern Europe, which will be both drier and warmer, yields are expected to decline. Irrigation may not be the answer: the harvest from irrigated fields is likely to start showing a decline by the mid-2030s.

By 2050, crop prices are likely to be depressed by the impacts of climate change. In effect, farmers could expect lower output, and on top of that, lower incomes per unit of output.

And these calculations do not include the direct impact of weather extremes – the heatwaves that shrivel seedlings, the hailstorms and high winds that damage blossom and so on – that are likely to be amplified by overall global warming.

“Under a high warming scenario, several climate impacts show a clear geographical north-south divide. Most of the welfare losses … would be greatly reduced under a 2°C scenario”

Transport, too, will be at the mercy of ever more intense and more frequent extremes of weather. By the century’s end, 200 airports and 850 seaports – large and small – could be affected by flooding from either rising sea levels or heavier downpours.

And the Mediterranean climate zone – with its unique mix of habitat, ground cover, biodiversity and crops – would become increasingly vulnerable to droughts, fires, pests and invasive alien species.

Labour productivity will fall, especially in the south, and in some places employers might have to plan to shift some work to the cooler night, with the additional costs of chronic fatigue, anxiety and depression associated with night work.

At 3°C, heat extremes could lead to additional deaths per year up to 132,000. But even at 2°C this figure could soar to 58,000 extra deaths per year. – Climate News Network

Doubled raw materials use is climate risk

We’re using more and more raw materials to build the world anew: our demands will almost have doubled by 2060. That’s bad news for the climate.

LONDON, 24 October, 2018 − Just when you might think the world has heard an unmistakable warning of the need to curb climate change drastically and fast, along comes another warning, about humans’ voracious appetite for the raw materials we use so profligately.

Its message is simple: one of the main causes of the Earth’s growing warmth is likely to be twice as severe 40 years from now as it is today.

This latest warning, from the club of the world’s richest countries, the Organisation for Economic Co-operation and Development (OECD), says consumption of raw materials is on course to nearly double by 2060 as the global economy expands and living standards rise.

And that will mean a steep increase in emissions of the greenhouse gases which drive global warming. Total emissions are projected to reach 75 gigatonnes (Gt) of carbon dioxide equivalent (CO2-eq.) by 2060, of which materials management would constitute about 50 Gt CO2-eq. A gigatonne is a thousand million tonnes. Gt CO2eq is an abbreviation for “gigatonnes of equivalent carbon dioxide”, a unit based on the global warming potential of different gases.

“More than half of all greenhouse gas emissions are related to materials management activities”

If you find it hard to visualise raw material, the OECD offers some helpful examples. The main sort of “stuff” it’s talking about includes the building blocks of the modern world: sand, gravel and crushed rock. Metals are next, and third is coal. It uses a disarmingly wide image to bring the message home: “The total raw materials consumed by an average family in a day would fill up a bathtub”.

The full OECD report, the Global Material Resources Outlook to 2060, will be available from 27 November, but a preview  was released this week at the World Circular Economy Forum in Yokohama, Japan.

The Outlook expects global materials use to rise from 90 gigatonnes (GT) today to 167 GT in 2060, because of the increase in world population to 10 billion people expected by then, and the rise in average global income per capita to converge with the current OECD level of US$40,000 (€34,900).

Immense human footprint

The projected figures are immense. But so are those that quantify today’s hunger for materials. Scientists calculate, for instance, that the weight of objects made by humans is about 30 trillion tonnes, and that by 2050 we shall have built another 25 million km of roads, enough to circle the Earth 600 times. None of this bodes well for us, let alone for the other species that share the planet.

Without action to address these challenges, the projected increase in the extraction and processing of raw materials such as biomass, fossil fuels, metals and non-metallic minerals is likely to worsen the pollution of air, water and soils, and contribute significantly to climate change, the OECD says.

This increase will happen despite both a shift from manufacturing to service industries and continual improvements in manufacturing efficiency, which has lessened the amount of resources consumed for each unit of GDP.

Without this, it says, environmental pressures would be even worse. The projection also acknowledges flattening demand in China and other emerging economies as their infrastructure booms end.

Coal boom

The preview report says the biggest rises in resource consumption will be in minerals, including construction materials and metals, particularly in fast-growing developing economies. The OECD projects a big increase in coal consumption by 2060, but a much smaller increase for oil.

Its overall conclusion on the impact of materials use on climate change is bleak: “More than half of all greenhouse gas (GHG) emissions are related to materials management activities. GHG emissions related to materials management will rise to approximately 50 Gt CO2-equivalent by 2060.”

The report’s global environmental impact analysis of the extraction and production of seven metals (iron, aluminium, copper, zinc, lead, nickel and manganese) plus building materials − concrete, sand and gravel − also shows significant impacts in areas like acidification, air and water pollution, energy demand, human health and the toxicity of water and land. − Climate News Network
