Science suggests possible climate link to Covid-19

Researchers think there could be a climate link to Covid-19. In which case, worse could yet happen.

LONDON, 5 February, 2021 − British and US scientists think there may be a connection between global heating driven by profligate fossil fuel use, and the emergence of the bat-borne virus that has triggered a global pandemic and has so far claimed more than two million lives worldwide − in short, a possible climate link to Covid-19.

The connection is possibly quite simple. Rising average temperatures encouraged a change in the natural vegetation of the forests of Yunnan, the southern Chinese province, close to the forests of Laos and Myanmar.

What had been tropical shrubland shifted to tropical savannah and deciduous woodland: the province became a suitable habitat for many bat species. It is also home to the scaly anteater known as the pangolin, and the masked palm civet: both of these have been also proposed as intermediate carriers of the virus. 

And, researchers say, in the last century an additional 40 bat species moved into Yunnan: these may have delivered 100 more types of bat coronavirus to the pool of potential infection.

Magnet for bats

And this “global hotspot” − far from the city where the first human cases were first confirmed − is where all the genetic data suggest that the coronavirus known as SARS-CoV-2 may have arisen, says a study in the journal Science of the Total Environment.

“Climate change over the last century has made the habitat in Yunnan province suitable for more bat species,” said Robert Beyer of the University of Cambridge, now at the Potsdam Institute for Climate Impact Research in Germany, who led the research.

“Understanding how the global distribution of bat species has shifted as a result of climate change may be an important step in reconstructing the origin of the Covid-19 outbreak.”

That animals carry viruses which can infect other species is well established: the HIV-Aids pandemic, the Ebola outbreaks in Africa and many other infections have all been linked to animal-to-human transmission.

For decades, scientists have been recording new “zoonotic” or animal-borne diseases in humans at the rate of two a year. An estimated 80% of all the viruses linked to human disease are of animal origin, including rabies.

“The fact that climate change can accelerate the transmission of wildlife pathogens to humans should be an urgent wake-up call to reduce global emissions”

The link between human disturbance of wilderness and disease outbreak has been made before, and more than once. A study by Cambridge scientists last year identified 161 steps humankind could take to reduce the ever-growing risks of zoonotic infection that could lead to even more devastating pandemics.

The case for bat transmission of SARS-CoV-2 driven by climate change remains circumstantial. It identifies a suspect and a set of possibly incriminating connections, but does not deliver the evidence for a secure conviction.

Using global records of temperature, rainfall and cloud cover, the scientists behind the latest study mapped global vegetation as it must have been a century ago. Then they used what they knew of the ecology of the world’s bat species to estimate the global distribution of each species 100 years ago. And then they matched this with records of species distribution in the last decade.

“As climate change altered habitats, species left some areas and moved into others − taking their viruses with them. This not only altered the regions where viruses are present, but most likely allowed for new interactions between animals and viruses, causing more harmful viruses to be transmitted or evolve,” Dr Beyer said.

There are more than 1,400 species of bat worldwide: these carry around 3,000 kinds of coronavirus, in ways that are mostly harmless to the host.

Risk increases

If the number of bat species increases, in a region also occupied by humans, then the risk of the infection of a new host, via bat urine, faeces, saliva or other transmission, also increases.

Bat viruses have been linked to Middle East Respiratory Syndrome, or MERS, and Severe Acute Respiratory Syndrome Cov-1 and CoV-2.

The region of Yunnan identified as now richer in bat species is also home to the pangolin, and one theory is that the virus jumped from bat to pangolin, or bat to masked palm civet, and then to humans when a pangolin was sold at a wildlife market in Wuhan, in Hubei province, more than 1200 kilometres away, where the first cases of Covid-19 were detected..

The implication of such a research finding is that, if human disturbance of the natural world increases the chance of such animal-to-human infection, then it will happen again. And it could happen with even greater potential loss of life.

That is why the discovery of this possible climate link to Covid-19 will now attract the minutest attention not only of scientists but of policymakers across the world.

Direct virus lessons we can learn as we go

Learning from pandemics is hard but vital. We need 1918’s virus lessons this time round to show us a better normal.

LONDON, 8 April, 2020 – What history knows as the 1918 ‘flu pandemic infected about a quarter of the world’s population at the time – around 500 million people – and left virus lessons for this generation, whether or not it’s learned them.

Thankfully, the 2020 coronavirus outbreak shows no sign yet of matching last century’s virulence. There are growing calls, though, for the world not just to get back to normal, but to turn this global horror into an opportunity to rebuild by finding a better normal to reclaim.

In late 2018 the Rapid Transition Alliance was launched with the intention of building a community to learn from moments of sudden change and to apply those lessons to the climate emergency.

Changes in the biosphere are happening faster than changes in human behaviour, so the question the Alliance asks is this: how do we match the speed and scale of social and economic change with the science – and what it is telling us to do?

It is now working with two other British organisations, the original Green New Deal group and Compass, the campaign that builds support for new ideas among social movements, decision-makers and political parties.

“Once people have seen what it is possible for a nation to do, and how fast it can do it, it is much harder for those in power to justify inaction, or wrong action”

In the first of several digital meetings the three have begun to sketch out a framework for how society can “learn as we go” from unprecedented events. They have identified five principles for a just recovery, which say in essence:

  • Health is the top priority, for all people, with no exceptions. That means resourcing health services everywhere and ensuring access for all.
  • Providing economic relief directly to the people is vital, particularly those marginalised in existing systems. Concentrate on people and workers and on short-term needs and long-term conditions.
  • Assistance directed at specific industries must be channelled to rescuing communities and workers, not shareholders or corporate executives, and never to corporations whose actions worsen the climate crisis.
  • The world needs to create resilience for future crises by creating millions of decent jobs that will help power a just transition for workers and communities to the zero-carbon future we need.
  • We must build solidarity and community across borders: do not empower authoritarians, do not use the crisis as an excuse to trample on human rights, civil liberties, and democracy.

An indication of the degree of international support for the five principles is available here.

Making things happen

The principles are already accepted by millions of people, but are no closer to reality, for all that. If they were, the climate crisis would be almost over. What can the three groups offer to make them happen?

The coordinator of the Rapid Transition Alliance is Andrew Simms, author of a summary of what the discussions have agreed so far. He told the Climate News Network: “Nobody can guarantee that things will turn out any certain way.

“But once people have seen what it is possible for a nation to do, and how fast it can do it, it is much harder for those in power to justify inaction, or wrong action.

“The current pandemic crisis is wreaking havoc on families, communities and whole economies. But it is also changing our ideas about what really matters to people and also what it is possible to do as a nation when faced with a great challenge.

“There is a new appreciation of key workers who provide the goods and services that a society really relies on – like health services and those in the food supply chain – but who typically lack recognition or are poorly paid.

Good-bye to inertia

“One of the greatest enemies in overcoming the climate emergency has been the sheer inertia of business-as-usual. Now there is a great sense of people taking stock of what is truly important.

“Vitally, when there is a fundamental threat to society, we have seen that financial resources can be mobilised. Fundamental change cannot happen without there being a consensus that it is both desirable and possible.

“The last few weeks have made visible underlying cracks in society, but also our ability to fix them. Once people have seen that, they are unlikely to settle for less.”

This first meeting spent some time talking practicalities, including how to protect wages and income. One example was the call by a member of Parliament for the introduction of a basic income scheme. Globally, the pandemic has prompted the United Nations to call for a worldwide ceasefire.

Overall, the summary says, greater consensus is emerging on how our economy and way of life relies on public not private interests, from health services to community aid groups, and that both local and national government have a vital enabling role on the need to improve the resilience of the economy at a national and local level.

Broadband before wheels

A radical reappraisal of transport came days after the meeting from the president of the UK’s Automobile Association (AA), Edmund King, who predicted a major shift in behaviour after the pandemic.

“People travelling up and down motorways just to hold meetings is inefficient, expensive and not good for the environment”, he said. “I think the use of road and rail and indeed bus will be reduced after this crisis.”

The AA, seen for years as a stalwart member of the roads lobby, said government funds for new transport infrastructure, including roads, might be better spent on improving broadband access to support home working.

The meeting agreed that the UK economy lacks a supportive town centre retail banking infrastructure with the capacity to administer a support scheme.

The build-up to the 2007-2008 financial crisis saw the evacuation of local banking services from the high street, and now the pandemic was making clear that the withering of local financial infrastructure in the UK must be reversed.

Universal and more mutual banking services are needed to build more resilient local economies, the three groups agreed. More progressive business models like social enterprises, which have direct community links, and the co-operative movement may help to provide answers. – Climate News Network
