Covid-19’s viral lessons for climate heating

In the midst of the coronavirus epidemic, Covid-19’s viral lessons offer a warning of what may lie ahead.

LONDON, 2 April, 2020 − There are some glimmers of hope discernible in the loss, confusion and misery that’s spreading worldwide, and one is that Covid-19’s viral lessons could help to equip us all to tackle the climate crisis that’s remorselessly building up.

A major side effect of the battle against the spread of the corona virus, for example, has been a significant reduction in the amount of climate-changing greenhouse gas being pumped into the atmosphere.

Power plants and factories in China and elsewhere have been shut down: the use of fossil fuels, particularly oil, has plummeted.

As a result of this reduced pollution, millions of people in cities and regions across the world are breathing fresher, cleaner air.

The epidemic has had other environmental consequences: residents of Venice in northern Italy say they have never seen such clear water in the city’s canals, mainly due to the dramatic drop in tourist numbers.

With several countries in lockdown, car and truck traffic no longer clogs up the roads and motorways.

“Covid 19 is a test of how the world copes with crisis. Climate change will present a much greater challenge”

Starved of passengers, many airlines have grounded planes. One of the big problems facing oil companies now is what to do with vast amounts of unsold jet fuel: some are resorting to storing it in tankers at sea.

Of course, whenever the virus is finally banished, industrial production could be ramped up again and fossil fuel emissions return to former levels.

But maybe, just maybe, some lessons are being learned as a result of the epidemic. One is obvious – that we are all in this together.

Covid-19, like climate change, knows no boundaries, respects no borders. It has become clear that nations cannot retreat to their bunkers and fight the virus alone. As with the battle against climate change, international action and cooperation are vital.

Another lesson is that science – painstaking analysis and the collection of data, both locally and at an international level – is essential if Covid-19 and other associated epidemics that might arise in the future are to be defeated.

Warnings ignored

Epidemiologists have constantly warned of the likelihood of the worldwide spread of a virus, saying it is not a case of if, but when. For the most part, they have been ignored.

In the same way, climate scientists have been warning for decades of the catastrophe threatened by global heating. Covid-19 shows how vital it is to listen to the science. Perhaps the epidemic will prompt a more urgent approach to climate change.

Covid-19 also reinforces the difficult-to-get-hold-of concept that nothing is normal any more. Suddenly the world has been turned into a very uncertain place. Behaviour which many of us have taken for granted, such as international travel, is, for now at least, no longer acceptable, or good for our health.

Scientists say climate change will mean even greater and more sustained adjustments to our lives. Rising seas will result in the displacement of millions of coastal dwellers. Floods and droughts will cause agricultural havoc and severe food shortages. People will have to adjust to a new – and constantly changing – reality.

Leadership and a clarity of policy – again, both at a national and international level – have been shown to be essential in fighting the coronavirus. After initial failings, China and South Korea moved to impose a strict and comprehensive regime to control the epidemic.

Specialists in those and several other countries have shared their experience and data with other nations.

‘Fantasy’ virus

Unfortunately, others − in particular Donald Trump in the US and Jair Bolsonaro in Brazil − have not acted in the same way, or shown a willingness to take strong, decisive action.

In the US, President Trump has in the past dismissed global warming as a hoax and withdrawn the US from the Paris Agreement on climate change. At the start of the Covid-19 outbreak, the virus was dismissed by the White House in similar terms.

Though Trump has since adjusted his message, valuable time has been lost. As the infection rate and death toll rise, the World Health Organisation is warning that the US is now in danger of becoming the world epicentre of Covid-19.

In Brazil, Bolsonaro – he refuses to believe in climate change − describes Covid-19 as a fantasy, suggesting it’s all a plot by China to weaken the country’s economy. Opposition to Bolsonaro’s lack of action on the pandemic is growing.

Renewable energy could power the world by 2050

Wind, water and solar sources − the renewable energy trio − could meet almost all the needs of our power-hungry society in 30 years.

LONDON, 19 February, 2020 − Virtually all the world’s demand for electricity to run transport and to heat and cool homes and offices, as well as to provide the power demanded by industry, could be met by renewable energy by mid-century.

This is the consensus of 47 peer-reviewed research papers from 13 independent groups with a total of 91 authors that have been brought together by Stanford University in California.

Some of the papers take a broad sweep across the world, adding together the potential for each technology to see if individual countries or whole regions could survive on renewables.

Special examinations of small island states, sub-Saharan Africa and individual countries like Germany look to see what are the barriers to progress and how they could be removed.

In every case the findings are that the technology exists to achieve 100% renewable power if the political will to achieve it can be mustered.

“It seems that every part of the world can now find a system that edges fossil fuels out in costs”

The collection of papers is a powerful rebuff to those who say that renewables are not reliable or cannot be expanded fast enough to take over from fossil fuels and nuclear power.

Once proper energy efficiency measures are in place, a combination of wind, solar and water power, with various forms of storage capacity, can add up to 100% of energy needs in every part of the planet.

Stanford puts one of its own papers at the top of the list. It studies the impacts of the Green New Deal proposals on grid stability, costs, jobs, health and climate in 143 countries.

With the world already approaching 1.5°C of heating, it says, seven million people killed by air pollution annually, and limited fossil fuel resources potentially sparking conflict, Stanford’s researchers wanted to compare business-as-usual with a 100% transition to wind-water-solar energy, efficiency and storage by 2050 – with at least 80% by 2030.

By grouping the countries of the world together into 24 regions co-operating on grid stability and storage solutions, supply could match demand by 2050-2052 with 100% reliance on renewables. The amount of energy used overall would be reduced by 57.1%, costs would fall by a similar amount, and 28.6 million more long-term full-time jobs would be created than under business-as-usual.

Clean air bonus

The remarkable consensus among researchers is perhaps surprising, since climate and weather conditions differ so much in different latitudes. It seems though that as the cost of renewables, particularly wind and solar, has tumbled, and energy storage solutions multiplied, every part of the world can now find a system that edges fossil fuels out in costs.

That, plus the benefit of clean air, particularly in Asian countries like India and China, makes renewables far more beneficial on any cost-benefit analysis.

The appearance of so many papers mirrors the consensus that climate scientists have managed to achieve in warning the world’s political leaders that time is running out for them to act to keep the temperature below dangerous levels.

Since in total the solutions offered cover countries producing more than 97% of the world’s greenhouse gases, they provide a blueprint for the next round of UN climate talks, to be held in Glasgow in November. At COP-26, as the conference is called, politicians will be asked to make new commitments to avoid dangerous climate change.

Russia moves to exploit Arctic riches

As the polar sea ice vanishes faster, Russia unveils plans to exploit Arctic riches: fossil fuel deposits, minerals and new shipping routes.

LONDON, 7 January, 2020 − The Russian government has published ambitious plans to exploit the Arctic riches off its northern coast, opening up the polar region to exploitation with a fleet of 40 ships, new roads and railways and four enlarged airports.

The plans, posted in Russian on the official government website on 30 December and signed off by prime minister Dmitry Medvedev, have been translated and reported by the independent Barents Observer newspaper, based in Norway.

The scale of the plans will alarm other Arctic nations, particularly Canada, the United States, Norway and Finland, which all have coastlines on the increasingly ice-free Arctic Ocean.

None of these has the powerful nuclear-propelled ships required to compete with Russia’s existing fleet, let alone the new ones it intends to build.

Although the Russian plans will not be completed until 2035, because the scale of shipbuilding alone is enormous, work has already begun and many of the preparations are going forward this year with a regional geological survey being conducted to pinpoint the riches to be exploited.

“In the 21st century, there will be a maritime ‘gold rush’ to the upper latitudes once conditions permit”

The Barents Observer reports that the plan builds on decrees issued by President Putin from May 2018, and a request to boost annual shipments on the Northern Sea Route across the top of Siberia to 80 million tons by 2024.

Although Rosatom, the giant state-controlled nuclear company, is leading the push to exploit the Arctic, and has already led the way with a floating nuclear power station to help provide power, there are a host of other leading Russian companies involved.

The fact that they are mostly involved in fossil fuel extraction and mineral mining will send a shiver down the spine of all those who believe that the Arctic should be left alone – and that exploiting its potential riches will ensure the destruction of much of the planet through climate change.

The Russians, on the other hand, see the Arctic as their own backyard and climate change as a way of gaining both economic and financial advantage, because Siberia will become much warmer.

Tax-free incentive

Enterprises involved include oil and gas companies Novatek, Gazprom Neft, Rosneft and the Independent Oil Company. In addition there are mineral and ore developers like Nornickel, VostokCoal, Baimskaya, KAZ Minerals, Vostok Engineering and Severnaya Zvezda.

The plans involve around 40 new vessels, several of them huge nuclear ice-breakers, designed to keep shipping lanes open in all circumstances. New railway lines, roads and bridges will be built in northern Siberia, with four airports upgraded to bring in supplies and people. Both companies and people will be encouraged by a special tax-free status for the region.

Exactly what is there to be exploited is not yet known. However, the Maritime Executive website has this to say: “What is generally understood is that there are vast resources to be harnessed. It is estimated that 30% of the world’s untapped hydrocarbons can be found in the Arctic, including a full 25% of proven hydrocarbon reserves.

“Much nickel, platinum, palladium, lead, diamonds, and other rare Earth metals are there as well. In the 21st century, there will be a maritime ‘gold rush’ to the upper latitudes once conditions permit.”

By coincidence the US Congressional Research Service put out an updated research paper on the Arctic on 20 December, discussing the tensions in the region.

American anxiety

Even before the latest Russian announcement there was concern in Washington that an Arctic takeover was planned. The document quotes US Secretary of State Michael Pompeo: “We’re concerned about Russia’s claim over the international waters of the Northern Sea Route, including its newly announced plans to connect it with China’s Maritime Silk Road.

“In the Northern Sea Route, Moscow already illegally demands other nations request permission to pass, requires Russian maritime pilots to be aboard foreign ships, and threatens to use military force to sink any that fail to comply with its demands.

“Just because the Arctic is a place of wilderness does not mean it should become a place of lawlessness. It need not be the case. And we stand ready to ensure that it does not become so.”

Global climate treaty is not working

Three out of four nations have yet to start to honour the global climate treaty. The world waits, the seas go on rising – and greenhouse gases too.

LONDON, 13 November, 2019 – Three nations in every four that vowed in the global climate treaty, the Paris Agreement, to contain global heating to “well below” 2°C by the century’s end have failed to deliver pledges that will reduce emissions by even 40% by 2030.

In Paris in 2015, a total of 195 nations agreed that action was vital. Since then only 36 countries have taken steps to meet the targets they agreed, according to a new study by the Universal Ecological Fund. And one nation has announced that it will withdraw altogether from the agreement.

“The comprehensive examination found that with few exceptions, the pledges of the rich, middle income and poor countries are insufficient to address climate change,” said Sir Robert Watson, once chair of the Intergovernmental Panel on Climate Change, which was present at the Paris meeting, and co-author of the study. “Simply, the pledges are far too little, too late.

“Even if all climate pledges, which are voluntary, are fully implemented, they will cover less than half of what is needed to limit the acceleration of climate change in the next decade.”

“The more carbon we release now the more sea level rise we are locking in for the future”

What happens now will affect the planetary climate and its ocean systems for much longer than that for at least the next two centuries. Researchers report in the Proceedings of the National Academy of Sciences that they looked at the impact to come even if all nations were to honour all the pledges made in Paris.

They agree that the global emissions of greenhouse gases since Paris and by 2030 would alone be enough to raise global sea levels by 20 cms: half of that from China, the US, the EU, India and Russia, the top five emitters. But they add a much more ominous long-term warning

“Our results show that what we do today will have a huge effect in 2300. 20 cms is very significant; it is basically as much sea-level rise as we’ve observed over the entire 20th century. To cause that with only 15 years of emissions is quite staggering”, said Alexander Nauels, of Climate Analytics, who led the study.

“The true consequences of our emissions on sea level rise unfold over centuries, due to the slow pace at which the ocean, polar ice sheets and glaciers respond to global warming. The more carbon we release now the more sea level rise we are locking in for the future.”

And as if to add force to the need for drastic action, a new US and German study has warned that even if nations honour their pledges by 2030, sea levels around the world will go on rising, and stay at higher levels for thousands of years.

Leaking permafrost

As the polar ice retreats, and rising tides batter the shores of the Arctic Ocean, vast volumes of carbon dioxide so far imprisoned  in the permafrost of the polar coasts – 34% of all the world’s coastlines  – could escape to accelerate further warming and of course yet greater sea level rise.

Climate scientists have been wrestling for decades with what they call the carbon budget – the accounting of all the ways in which carbon dioxide gets into the atmosphere and out of it again – and missed another potentially dangerous source of the greenhouse gas.

As glaciers retreat and the frozen coasts and soils thaw, this could begin to seep into the atmosphere. Laboratory experiments suggest it will seep even faster as sea levels rise and waves grow more powerful. For every gram, dry weight, of eroded permafrost, more than 4 grams of carbon dioxide would escape into the atmosphere.

“Carbon budgets and climate simulations have so far missed coastal erosion in their equations even though it might be a substantial source of carbon dioxide,” says George Tanski of Vrije Universiteit Amsterdam, the lead author.

“Our research found that the erosion of permafrost coastlines can lead to the rapid release of significant quantities of CO2, which can be expected to increase as coastal erosion accelerates, temperatures increase, sea ice diminishes and stronger storms batter Arctic coasts.”

Early warning

That the Paris Agreement was backed up by pledges that might fail to contain global warning to an ideal target of 1.5°C was clear from the start, and scientists who looked at the promises made at the time warned that unless they were increased, they committed the world to a warming of at least 3°C above the long term average for most of human history.

The latest study from the Universal Ecological Fund now finds that not only are the pledges not enough; some are not being honoured. China and India pledged to reduce the intensity of their emissions relative to gross domestic product, but since their economies continue to grow, so will their emissions.

China already contributes more than 26% of all global emissions, India 7%. The US, which contributes 13% of all greenhouse emissions, is to quit the Paris Agreement in 2020, and has in any case reversed much of its climate legislation. Russia, which contributes 4.6% of all atmospheric carbon dioxide, has submitted no pledges.

Europe’s 28 nations, and seven others, have promised to reduce emissions by 40% by 2040. Of the remaining 152 nations, responsible for more than 36% of all emissions, 127 have submitted conditional plans, but rely upon technical assistance and funding from the wealthy nations to execute these. But the US and Australia have stopped making contributions to such funding.

Almost 70% of emissions are from fossil fuels: successful action would require the closure of 2,400 coal-fired power stations. In fact, 250 new coal-fired power stations are now under construction. The message is that governments are doing too little, too slowly, leaving horrendous future consequences. – Climate News Network

Of the remaining 152 nations, responsible for more than 36% of all emissions, 127 have submitted conditional plans, but rely upon technical assistance and funding from the wealthy nations to execute these. But the US and Australia have stopped making contributions to such funding.

Almost 70% of emissions are from fossil fuels: successful action would require the closure of 2,400 coal-fired power stations. In fact, 250 new coal-fired power stations are now under construction. The message is that governments are doing too little, too slowly, leaving horrendous future consequences. – Climate News Network

Human ancestors lived in a low-carbon world

Carbon dioxide levels are higher now than in all human history, and prehistory too: a low-carbon world nurtured our distant forebears.

LONDON, 4 October, 2019 – For the entire 2.5 million years of the Ice Age epoch called the Pleistocene, it was a low-carbon world. Atmospheric carbon dioxide hovered around 230 parts per million. Not only did Homo sapiens evolve on a low-carbon planet, so did Homo erectus and most other human species now known only from fossil evidence in Europe and Asia.

And this long history of a planet kept cool and stable by low levels of greenhouse gas in the atmosphere continued long after the discovery of fire, the Stone Age, the Bronze Age, the Iron Age, the fall and rise of empires and the Industrial Revolution.

Only in 1965 did carbon dioxide levels pass 320 ppm, after a century of exploitation of fossil fuels that released ancient carbon back into atmospheric circulation.

By 2019, the carbon dioxide concentration in the atmosphere had tipped 410 ppm and is still rising. In less than a century, human action had raised planetary average temperatures by around 1°C. At present rates, this average could reach 3°C by the end of this century.

Researchers have known for a century that humans emerged in a cooler world, but much of the story of the distant past was based on the evidence of fossils and sedimentary rocks. The latest research pushes the detailed atmospheric carbon dioxide accounting back to at least 2.5 million years.

“This current high carbon dioxide experiment is not only an experiment for the climate and the environment – it’s an experiment for us”

Researchers report in the journal Nature Communications that they studied the pattern of carbon isotope readings preserved in the deep yellow soils of China’s loess plateau. What they found confirmed 800,000 years of annual evidence from the ice cores of Antarctica and Greenland – and far beyond that limit.

The wind-blown loess of China dates back to at least 22 million years and each successive layer carries isotope evidence that can be read as testimony to the atmospheric conditions in which the soils were laid down.

The latest find confirms that the normal state of the planet during human evolution was cool, with low levels of atmospheric carbon. Homo erectus was the first known human predecessor to exploit fire, systematically fashion stone hand axes, and to leave Africa for Asia and Europe.

“According to this research, from the first Homo erectus, which is currently dated to 2.1 to 1.8 million years ago, we have lived in a low-carbon environment – concentrations were less than 320 parts per million,” said Yige Zhang, a geoscientist at Texas A&M University in the US, who worked with colleagues in Nanjing, China, and California Institute of Technology.

Healthcare can worsen global climate crisis

Healthcare workers urging zero carbon emissions say chemicals used increasingly to anaesthetise patients are potent greenhouse gases.

LONDON, 11 September, 2019 − If the global healthcare sector were a country, it would be the fifth-largest greenhouse gas (GHG) emitter on the planet, according to a new report. Its authors, who argue for zero carbon emissions, say it is the first-ever estimate of healthcare’s global climate footprint.

While fossil fuel burning is responsible for more than half of the footprint, the report says there are several other causes, including the gases used to ensure that patients undergoing surgery feel no pain.

It is produced by Health Care Without Harm (HCWH), an international NGO seeking to change healthcare worldwide so that it reduces its environmental footprint and works for environmental health and justice globally. It was produced in collaboration with Arup.

The report says the European Union healthcare sector is the third largest emitter, accounting for 12% of the global healthcare climate footprint. More than half of healthcare’s worldwide emissions come from the top three emitters – the EU, the US and China. The report includes a breakdown for each EU member state.

An earlier report, published in May this year in the journal Environmental Research Letters, said the health care sectors of the 36 countries sampled were together responsible in 2014 for 1.6 GtCO2e (gigatonnes of carbon dioxide equivalent), or 4.4% of the total emissions from these nations, and 4.4% is the total used in the HCWH report.

(Carbon dioxide equivalency is a simplified way to put emissions of various GHGs on a common footing by expressing them in terms of the amount of carbon dioxide that would have the same global warming effect, usually over a century.)

“Places of healing should be leading the way, not contributing to the burden of disease”

HCWH says well over half of healthcare’s global climate footprint comes from fossil fuel combustion. But it identifies several other causes for concern as well. One is the range of gases used in anaesthesia to ensure  patients remain unconscious during surgery.

These are powerful greenhouse gases. Commonly used anaesthetics include nitrous oxide, sometimes known as laughing gas, and three fluorinated gases: sevoflurane, isoflurane, and desflurane. At present, the greater part of these gases enter the atmosphere after use.

Research by the UK National Health Service (NHS) Sustainable Development Unit shows the country’s anaesthetic gas footprint is 1.7%, most of it attributable to nitrous oxide use.

The UN climate change convention (UNFCCC) found that in 2014 a group of developed nations with 15% of the global population, 57% of the global GDP and 73% of global health expenditure was also responsible for 7 MtCO2e of medical nitrous oxide use. (“MtCO2e” means “million metric tons of carbon dioxide equivalent”.)

The UNFCCC concluded that the full impact of the gas’s global use in anaesthesia “can be expected to be substantially greater”.

Use is growing

For fluorinated gases used in anaesthesia, global emissions to the  atmosphere in 2014 were estimated to add 0.2% to the global health care footprint. Because of the growing use of these gases, increasingly chosen  in preference to nitrous oxide, the footprint from anaesthetic gases is also likely to increase.

In measured tones, HCWH says: “Wider adoption of waste anaesthetic capture systems has the potential to be a high impact health care-specific climate mitigation measure” – or in other words, trap them and dispose of them carefully before they can just escape through an open window to join the other GHGs already in the atmosphere.

But HCWH adds a warning: “For many individual health facilities and systems of hospitals the proportion of the contribution of both nitrous oxide and fluorinated anaesthetic gases to their climate footprint can be significantly higher.

“For instance, Albert Einstein Hospital in São Paulo, Brazil found that GHG emissions from nitrous oxide contributed to nearly 35% of their total reported GHG emissions in 2013.”

Its report said choosing to use desflurane instead of nitrous oxide meant a ten-fold increase in anaesthetic gas emissions.

Other remedies available

The HCWH report also sounds the alert about metered-dose inhalers (MDIs), devices which are typically used for the treatment of asthma and other respiratory conditions, and which use hydrofluorocarbons as propellants. These are also highly potent greenhouse gases, with warming potentials between 1,480 and 2,900 times that of carbon dioxide.

Again, though, the report says the full global emissions from MDIs will probably be much greater than today’s figure. Alternative ways of using MDIs, such as dry powder -based inhalers, it says, are available and provide the same medicines without the high global warming potential propellants.

The report argues for the transformation of the healthcare sector so that it meets the Paris Agreement goal of limiting temperature rise attributable to climate change to 1.5°C.

HCWH says hospitals and health systems should follow the example of the thousands of hospitals already moving toward climate-smart healthcare via the Health Care Climate Challenge and other initiatives.

Welcoming the report, the director-general of the World Health Organization, Dr Tedros Adhanom Ghebreyesus, said hospitals and other health sector facilities were a source of carbon emissions, contributing to climate change: “Places of healing should be leading the way, not contributing to the burden of disease.”− Climate News Network

Nuclear power somehow always makes a loss

As the world recalls the atomic bombing of Hiroshima 74 years ago, researchers say nuclear power can offer nothing in the fight against climate change.

LONDON, 6 August, 2019 − Two new studies together make an eloquent case against nuclear power: that its civilian uses are inseparable from nuclear warmaking, and that it is always uneconomic and has to be subsidised by taxpayers.

The first report, by the Berlin-based German Institute for Economic Research (DIW), says that private economic interests have never played a role in nuclear power; instead the military have always been the driving force behind their construction. The report’s title sums up its contents: High-Priced and Dangerous: Nuclear Power is not an option for the Climate-Friendly Energy Mix.

The researchers calculate, after analysis of the 674 nuclear power plants built since the 1950s, that on average they make a loss of €5 billion (US$5.6 bn) each, and that is without taking into account the cost of getting rid of their radioactive waste.

The report does not simply investigate the past. It also looks ahead, reviewing the industry’s plans for a new generation of nuclear power stations, and particularly the small modular reactors (SMRs) in which the US, Canada, Russia, China and the UK are currently investing huge amounts of development money. The researchers conclude that they too are doomed to be an expensive failure.

“Nuclear power was never designed for commercial electricity generation; it was aimed at nuclear weapons”

The second study, specifically into SMRs, is by the Nuclear Consulting Group (NCG), an international team of academics and other experts [the writer of this news report is a member].  It reaches the same conclusion: that they will be expensive for the taxpayer and never live up to expectations.

The NCG, which works with Nuclear Free Local Authorities in the UK, says its opposition is based on close scrutiny of the industry. After examining all the designs of SMRs currently being developed globally, the NCG says: “It remains likely that no substantive deployment of the technology will be realised, with just a very few reactors built, at most.

“This will be despite large amounts of public money being invested in these projects and, worse, the neglect of other more viable non-nuclear options. It provides another example of the industry talking a good game but delivering little.” There are recurrent reports that SMRs are managing to break into the market, but so far without any sign of widespread success.

The German report from DIW is much more direct in condemning nuclear power. Christian von Hirschhausen, co-author of the study, says: “Nuclear power was never designed for commercial electricity generation; it was aimed at nuclear weapons.

Long-term danger

“That is why nuclear electricity has been and will continue to be uneconomic. Further, nuclear energy is by no means ‘clean’; Its radioactivity will endanger humans and the natural world for over one million years.”

The assertion by DIW that civilian and military uses of nuclear power are two sides of the same coin has been made before, with a US report two years ago saying that an essential component of nuclear weapons is made in civil reactors for the use of the armed forces.

The DIW authors examine the history, financing and political background to every nuclear power station built. With 10 countries gaining the knowledge to produce nuclear weapons (initially the US, UK, France and the Soviet Union, joined later by China, India, Pakistan, North Korea, Israel, and South Africa), none of the ten now uses nuclear energy commercially via private, non-state-supported investment.

The German report’s conclusion is aimed at the Berlin government, but it would equally apply to any government not interested in developing nuclear power for military purposes, whether to make bombs or to power submarines and surface warships.

Not an option

It says: “The lack of economic efficiency goes hand-in-hand with a high risk with regard to the proliferation of weapons-grade materials and the release of radioactivity, as shown by the accidents in Harrisburg, known also as Three Mile Island (1979), Chernobyl (1986), and Fukushima  (2011). Nuclear energy is not a relevant option for supplying economical, climate-friendly, and sustainable energy in the future.

“Energy, climate, and industrial policy should therefore target a quick withdrawal from nuclear energy. Subsidies and special tariffs for service life extensions are not recommended because they are life-support systems for the risky, uneconomical nuclear industry. This is even more true for new construction. Budgets for researching new reactor types should be cut.

“‘Nuclear energy for climate protection’ is an old narrative that is as inaccurate today as it was in the 1970s. Describing nuclear energy as ‘clean’ ignores the significant environmental risks and radioactive emissions it engenders along the process chain and beyond.

Only a climate revolution can cool the world

An academic book on fossil fuel consumption reaches a startling conclusion: only a climate revolution can force governments to act to stop the planet overheating.

LONDON, 31 July, 2019 − Governments have completely failed to make progress in tackling the planetary emergency, and a climate revolution is the sole hope that they will do so.

This sounds like a sound bite from Greta Thunberg, the 16-year-old Swedish climate activist who is inspiring schoolchildren worldwide to go on strike, or a slogan from Extinction Rebellion, which has been disrupting city life in the UK and elsewhere to secure an urgent government response to the climate emergency.

Both campaigns might agree with the statement, but it is in fact from a scholarly book, Burning Up, A Global History of Fossil Fuel Consumption, a detailed study into the burning of fossil fuels since 1950.  It looks at fuel consumption in individual countries but also at the political forces that have driven and still drive the ever-growing inferno of fossil fuels, coal, oil and gas, across the world.

The book illustrates the reasons behind the rather frightening fact that since the Rio Earth Summit in 1992, despite many promises and warnings, governments have failed to take decisive action on climate change and in fact have made it decidedly worse by continuing to subsidise fossil fuels more than renewables.

Simon Pirani, a senior research fellow at the UK’s Oxford Institute for Energy Studies, takes the reader through an exhaustive examination of fossil fuel consumption and the driving forces behind it.  One point he makes is that governments, particularly in the US, have contrived to kill off the use of buses and trains and instead promoted private cars.

 

And even if people wanted a choice, they don’t have the chance to make one, so we have to contribute to the increased use of fossil fuels if we want to lead a normal life. Producing many consumer goods and nearly all food depends on fossil fuels. Agriculture depends on oil-based fertiliser; and buying cars, washing machines and fridges leaves customers willy-nilly indirectly consuming fossil fuels.

Pirani is also scathing about the rich world’s reaction to the sort of crisis that is here already and will become more commonplace in a warming world.  He gives the example of Hurricane Katrina in New Orleans in 2005, when there was indifference from the government to the poor and disadvantaged who were most affected – an attitude mirrored across the world in subsequent disasters, especially in developing countries.

Climate change is already affecting swathes of Africa, causing crop failures and famine – again largely ignored by the rich world, which he identifies as the main cause of climate change, continues to cause it, but refuses to take responsibility for its consequences.

His third example is our attitude to refugees. He admits that most of the migrants converging now on Europe and the US are on the move because of wars or political oppression, but says that when millions are forced to migrate by climate change the pattern has already been set.

“There is little hope of world leaders taking the action required to keep the world temperature from increasing more than 2°C, let alone 1.5°C”

The attitude of governments in the rich world, increasingly in the EU but already in the US, is to build walls to keep them out rather than tackle the problem at source.

Altogether it is a fascinating and disturbing analysis of how the influence of the fossil fuel industry and its short-term financial advantage has come to outweigh the scientific evidence and the welfare of humanity in the minds of politicians. It certainly demonstrates why there is little hope of world leaders taking the action required to keep the world temperature from increasing more than 2°C, let alone 1.5°C.

However, Dr Pirani claims that ordinary people can have an impact on governments.  He points to the example of China where the government, fearful of the reaction of its people to the effects of air pollution on its children’s health, has taken decisive action to reduce the damage. India is currently going through the same process.

His book was written and with the publisher before the rise of Extinction Rebellion and the school strikes, but perhaps that is exactly the sort of citizen action he would advocate.

His conclusion is that unless ordinary people reject the continued dominance of the fossil fuel industry and force governments to act by continued acts of civil disobedience. there is no hope of keeping the world temperature below a dangerous level. − Climate News Network

Solar future shines ever more brightly

Progress in China, the US and elsewhere shows an increasingly positive solar future as fuel from the sun grows cheaper and more abundant.

LONDON, 26 June, 2019 − The world’s solar future  continues to brighten, further and faster than seemed possible only a few years ago.

As the price of all types of solar technology goes on falling, it is becoming possible for large parts of the world to replace fossil fuels with cleaner and cheaper solar alternatives. A UN-backed report says much of Asia could meet all its electricity needs and ditch coal completely, by adopting solar power on a large scale.

After an initial drop of 2% in installations of solar equipment in the United States when President Donald Trump put a 30% tariff on overseas-manufactured solar panels, the market has picked up again and there are forecasts of a rapid growth rate this year.

The US Solar Energy Industries Association expects installations to rise by 25% in 2019 to a capacity of 13.3 gigawatts, about the output of 15 large coal-fired plants. This is more electricity than many smaller countries in Africa and Europe need to keep their lights on.

The boom in American solar power is due mainly to the continuous fall in the price of photo-voltaic panels, because of an over-supply in China. This has cancelled out the negative effect of Trump tariffs. States in the southern US, particularly Florida, are expecting to install large-scale solar farms this year that will produce electricity more cheaply than coal.

New technology

In China itself the solar boom continues. It has been strengthened by an innovation, a molten solar power plant in Dunhuang (in the north-western Gansu province, on the edge of the Gobi desert), costing three billion yuan (£345m/ $440m).

This uses 12,000 mirrors to concentrate the sun’s rays onto a tower containing molten salt which heats to a far greater temperature than water and creates steam to drive turbines and generate electricity.

The advantage of this concentrated solar power method over solar panels is that the heat can be stored in the salt and electricity produced in the evening when demand rises.

The 100 megawatt plant, enough to power a medium-sized city, can store energy for up to 15 hours, so it can work continuously and can re-charge itself when the sun comes up the following day. The Chinese engineers say the plant has already exceeded its design specifications.

The same technology is being used in Dubai, where an ambitious project, Noor Energy 1, will cover 44 square kilometres of desert. Costing $4.4 billion, it is the largest renewable energy project in the world, apart from hydropower, and combines both concentrated solar power and photo-voltaic technologies.

“The 1.5°C limit means a greatly reduced risk of drought and water stress in south and south-east Asia”

This combination is expected to produce 950 megawatts of power: it uses 550,000 tons of salt to store the heat. Again, the power output after sunset is expected to last for 15 hours. Dubai aims to generate 25% of its energy from solar power by 2030.

Although concentrated solar power plants take longer to construct and have a larger capital cost, the energy storage they provide makes them particularly attractive to desert states where the input from the sun is so reliable.

But the future for solar is bright over the whole of south and east Asia, according to a new report by Climate Analytics, which is supported by the United Nations. The study has seven country studies for India, Pakistan, Bangladesh, Thailand, Vietnam, Indonesia and the Philippines.

Climate Analytics researchers estimate that covering just 1.5% of the territory in each south and east Asian country with solar installations could satisfy their combined electricity consumption 13 times over.

Costs for renewables and energy storage technologies continue to fall: the average cost of renewables was often already in the same range as fossil fuels in 2016, even without accounting for external costs like health and the environmental impacts of fossil fuels. It has now fallen further.

Key contribution

However, for the world to limit warming to 1.5°C, these  countries need to decarbonise their energy systems by 2050, and the power sector has a critical role to play.

According to the study, the share of zero carbon electricity generation needs to reach at least 50% in 2030 and 100% by 2050. Coal would need to be phased out of electricity generation by 2040.

“By decarbonising their energy systems, south and south-east Asian countries can make a fundamental difference in global efforts to limit warming to 1.5°C, in line with the Paris Agreement, and will reap large economic and sustainable development benefits by doing so,” said the report’s author, Bill Hare, Climate Analytics’ CEO.

Dr Fahad Saeed, climate scientist at Climate Analytics, said: “The 1.5°C limit means a greatly reduced risk of drought and water stress in south and south-east Asia, which would contribute to achieving zero hunger, good health and wellbeing, and clean water and sanitation.”

“It would also reduce the risk of flooding for large numbers of people living in coastal regions, as well as extreme heat that can otherwise reach intolerable levels for human health and labour productivity, particularly in densely populated cities in south Asia.” − Climate News Network

Progress in China, the US and elsewhere shows an increasingly positive solar future as fuel from the sun grows cheaper and more abundant.

Human impact on climate is 100 years old

When did the human impact on climate begin? At least a century ago, with the arrival of the bi-plane, the chauffeur-driven car and the Jazz Age.

LONDON, 2 May, 2019 − Our influence on the Earth’s environment has lasted for a century: the human impact on droughts and moisture patterns began at least 100 years ago, researchers now say.

US scientists used new analytic techniques and almost a thousand years of tree-ring data to build up a picture of drought and rainfall worldwide for the last century. And they report in the journal Nature that they have identified the human fingerprint upon climate variation as far back as the first days of the motor car and the infant aircraft industry.

The pattern of change, in which regions prone to drought such as the western US became more arid, grew visible between 1900 and 1949. The researchers saw the same pattern of drying in those decades in Australia, Europe, the Mediterranean, western Russia and southeast Asia.

At the same time more rain and snow fell in western China, much of central Asia, the Indian subcontinent, Indonesia and central Canada.

Clear signal apparent

Kate Marvel of the Nasa Goddard Institute for Space Studies, who led the research, said: “It’s mind-boggling. There really is a clear signal of the effects of greenhouse gases on the hydroclimate.”

And Benjamin Cook of both the Nasa Institute and the Lamont-Doherty Earth Observatory at Columbia University, said: “We asked, does the real world look like what the models tell us to expect? The answer is yes.

“The big thing we learned is that climate change started affecting global patterns of drought in the early 20th century. We expect this pattern to keep emerging as climate change continues.”

For four decades it has been a given of climate change research that average planetary warming will intensify all the extremes of weather: in particular, drought and flood.

“All the models are projecting that you should see unprecedented drying soon, in a lot of places”

The problem has been that droughts and floods have always happened. But could scientists identify the signature of human change – the clearing of the forests, the intensification of agriculture, the growth of the cities and the ever-increasing use of fossil fuels to dump ever more carbon dioxide in the atmosphere – in any one flood or drought? Until this century, researchers were unwilling to name the guilty party.

No longer. In recent years researchers have done more than just blame overall warming on human activity, and in particular the increasing hazard of extremes of heat, drought and flood.

They have linked human behaviour with drought in California and with record temperatures in 2013 in Australia.

The Nasa-led research is not quite the first to claim to have detected very early evidence of climate change. A team led by Chinese scientists reported in April in the journal Nature Sustainability that tree ring evidence from the Tibetan plateau suggested that humans may have begun altering the pattern of seasonal temperatures – that is, the differences between winter and summer – as early as the 1870s, at least in the northern hemisphere.

Puzzle solved?

But the latest study from Dr Marvel and colleagues identifies such evidence on a wider scale, and may even have resolved the puzzle of the extremes that did not happen.

The research found three distinct periods of change. The first was marked by more drought in some places, more precipitation in others in the first half of the 20th century. But by the height of the Cold War, and the space race mid-century, it became harder to see a pattern, and climate events seemed more random, and climates cooler.

The researchers now think the huge volumes of aerosols from power stations, factory chimneys and vehicle exhausts between 1950 and 1975 altered weather patterns in different ways, affecting cloud formation, rainfall and temperature, to mask the effect of greenhouse gas increases.

These were the years of choking smog, grime and soot, sulphurous droplets, acid rain, corroding historic buildings and urban respiratory disease on an epidemic scale.

Stronger patternn expected

And then developed nations started introducing clean air legislation and other pollution controls. Round about 1981, tentative evidence of the impact of human-driven greenhouse gas emissions began to show again in the climate record, although not as boldly as in the first half of the century.

If the researchers have got it right, the pattern of increasing drought, matched elsewhere by increasing precipitation, will continue to become stronger.

“If we don’t see it coming in stronger in, say, the next 10 years, we might have to wonder whether we are right,” Dr Marvel said. “But all the models are projecting that you should see unprecedented drying soon, in a lot of places.”

And the researchers warn that the consequences for humankind, especially in North America and Eurasia, could be severe. − Climate News Network
