Climate crisis: in coronavirus lockdown, nature
bounces back – but for how long?

decreases, in the end it will be about the politics

After decades of relentlessly increasing pressure, the
human footprint on the earth has suddenly lightened.
The
environmental changes wrought by the coronavirus were first visible from space.
Then, as the disease and the lockdown spread, they could be sensed in the sky
above our heads, the air in our lungs and even the ground beneath our feet.
While the
human toll mounted horrendously from a single case in Wuhan to a global
pandemic that has so far killed more than 88,000 people, nature, it seemed, was
increasingly able to breathe more easily.
As
motorways cleared and factories closed, dirty brown pollution belts shrunk over
cities and industrial centres in country after country within days of lockdown.
First China, then Italy, now the UK, Germany and dozens of other countries are
experiencing temporary falls in carbon dioxide and nitrogen dioxide of as much
as 40%, greatly improving air quality and reducing the risks of asthma, heart
attacks and lung disease.
For many
experts, it is a glimpse of what the world might look like without fossil
fuels. But hopes that humanity could emerge from this horror into a healthier,
cleaner world will depend not on the short-term impact of the virus, but on the
long-term political decisions made about what follows.
After
decades of relentlessly increasing pressure, the human footprint on the earth
has suddenly lightened. Air traffic halved by mid-March compared with the same
time last year. Last month, road traffic fell in the UK by more than 70%, to
levels last seen when the Beatles were in shorts. With less human movement, the
planet has literally calmed: seismologists report lower vibrations from
“cultural noise” than before the pandemic.
Key
environmental indices, which have steadily deteriorated for more than half a
century, have paused or improved. In China, the world’s biggest source of carbon,
emissions were down about 18% between early February and mid-March – a cut of
250m tonnes, equivalent to more than half the UK’s annual output. Europe is
forecast to see a reduction of around 390m tonnes. Significant falls can also
be expected in the US, where passenger vehicle traffic – its major source of
CO2 – has fallen by nearly 40%. Even assuming a bounceback once the lockdown is
lifted, the planet is expected to see its first fall in global emissions since
the 2008-9 financial crisis.
There is no
doubt that these lockdowns are hitting the fossil fuel industry. With fewer
drivers on the roads and planes in the air, the price of oil has slumped almost
two-thirds since last year. Car sales fell by 44% in March, with motorway
traffic down 83%. So many more people are learning to teleconference from home
that the head of the Automobile Association in the UK advised the government to
switch infrastructure investment from building new roads to widening internet
bandwidth.
This is
potentially good news for the climate because oil is the biggest source of the
carbon emissions that are heating the planet and disrupting weather systems.
Some analysts believe it could mark the start of a prolonged downward trend in
emissions and the beginning of the end for oil. Others strike a more cautious
note about the fuel that has dominated our lives and polluted our atmosphere
for the past century.
“The drop
in emissions is global and unprecedented,” Rob Jackson, the chair of Global
Carbon Project said. “Air pollution has plunged in most areas. The virus
provides a glimpse of just how quickly we could clean our air with renewables.”
But he warned that the human cost was too high and the environmental gains
could prove temporary. “I refuse to celebrate a drop in emissions driven by
tens of millions of people losing their jobs. We need systemic change in our
energy infrastructure, or emissions will roar back later.”
Hopes that
the pandemic will accelerate the transition to a cleaner world are already
running into a political wall: the “shock doctrine” of disaster capitalism
outlined by the author and activist Naomi Klein. In her book of the same name,
the Canadian writer describes how a powerful global elite exploits national
crises to push through unpopular and extreme measures on the environment and
labour rights.
This is
what is happening in the United States and elsewhere. Oil company executives
have lobbied Donald Trump for a bailout. Under the cover of the crisis, the
White House has rolled back fuel-economy standards for the car industry, the
Environmental Protection Agency has stopped enforcing environmental laws, three
states have criminalised fossil fuel protesters and construction has resumed on
the KXL oil pipeline. The US government’s massive economic stimulus bill also
included a $50bn bailout for aviation companies. Environmental groups are
urging the UK and European Union not to do the same.
If governments
prime the economic pumps with the intention of a return to business as usual,
environmental gains are likely to be temporary or reversed. China provides some
indication of what can be expected. With no new cases in Wuhan, the lockdown is
being eased and energy use and air pollution have been rising since the end of
March.
Wildlife
and biodiversity
Nevertheless,
while our species is in temporary retreat during the lockdowns, wildlife has
filled the vacuum. This year will almost certainly see a much lower toll for
roadkill by cars and trucks, which – in the UK alone – annually takes the lives
of about 100,000 hedgehogs, 30,000 deer, 50,000 badgers and 100,000 foxes, as
well as barn owls and many other species of bird and insect. Many councils have
delayed cutting the grass on roadside verges – one of the last remaining
habitats for wildflowers – which should bring a riot of colour to the
countryside this summer and provide more pollen for bees.
Coyotes,
normally timid of traffic, have been spotted on the Golden Gate Bridge in San
Francisco. Deer are grazing near Washington homes a few miles from the White
House. Wild boar are becoming bolder in Barcelona and Bergamo, Italy. In Wales,
peacocks have strutted through Bangor, goats through Llandudno and sheep have
been filmed on roundabouts in a deserted playground in Monmouthshire.
This is
presented as the comedy in our tragedy. Cartoonists have depicted throngs of
tourist animals gawping through city windows at humans under lockdown.
Commentators are even talking of the “post-human” era – a mocking rejoinder to
the idea that we live in Anthropocene, a period of human domination that is
reshaping the planet. Humour does not get much blacker. We are laughing at our
own decline – and assuming that nature will be the beneficiary.
Environmental
campaigners say that is a dangerous misconception. The picture is different
across our unequal world. Rich, industrialised nations are seeing a temporary
recovery of nature because there is so little of it in the first place. Poorer
countries, on the other hand, especially in the southern hemisphere, fear an
increased threat to wildlife because the pandemic means they have less money
and personnel with which to conserve endangered species and habitats.
In the
Amazon rainforest, environmental authorities are reining in monitoring and protection
operations. In the Masai Mara and Serengeti, nature reserves are taking less
tourist revenue, which means they are struggling to pay rangers. Conservation
groups fear this will open the door to more illegal poaching, mining and
logging, especially now that local people are losing income and need new ways
to feed their families.
“In the
short term it would be dangerous to think that a downturn in economic activity
is a benefit to nature,” said Matt Walpole of Fauna and Flora International.
“There are significant risks.”
Potentially
offsetting this is reduced demand for many natural resources, but it remains to
be seen whether home isolation of half the world’s population affects the
appetite for consumer goods.
A new
future?
The respite
for nature will be less important than what follows. That is already being
decided in closed meetings while the public is locked down at home. Meanwhile,
global conferences intended to find solutions to environmental problems, such
as the Cop26 UN climate talks originally scheduled for Glasgow at the end of
this year, have been postponed.
UN leaders,
scientists and activists are pushing for an urgent public debate so that
recovery can focus on green jobs and clean energy, building efficiency, natural
infrastructure and a strengthening of the global commons.
“This is
the big political battle,” said Laurence Tubiana, CEO of the European Climate
Foundation and an architect of the Paris agreement. Leading scientists have
jointly signed an open appeal for governments to use recovery packages to shift
in a greener direction rather than going back to business as usual.
Ultimately,
the most important environmental impact is likely to be on public perceptions.
The pandemic has demonstrated the deadly consequences of ignoring expert
warnings, of political delay, and of sacrificing human health and natural
landscapes for the economy. Of new infectious diseases, 75% come from animals,
according to the United Nations Environment Programme. Compared with the past,
they pass more rapidly to humans through wildlife trafficking and deforestation
and then spread across the globe through air travel and cruise-ship tourism. China
– the world’s biggest market for wild animals – appears to have recognised this
by banning the farming and consumption of live wildlife. There are growing
calls for a global ban on “wet markets”.
The
pandemic has also shown that pollution lowers our resistance to disease. More
exposure to traffic fumes means weaker lungs and greater risk of dying from
Covid-19, according to scientists at Harvard University. As the UN’s
environment chief, Inger Andersen, put it, nature is sending us a message that
if we neglect the planet, we put our own wellbeing at risk.
Since the
start of the pandemic, it is not just from space that the world looks
different. The unthinkable is now thinkable. Positions are shifting.
Libertarian governments are curtailing freedoms more drastically than wartime
leaders. Austerity conservatives are approving trillions of dollars for
healthcare and emergency spending. Small-state advocates are being forced into
massive interventions. Leading business publications are calling for a deep reform
of capitalism. Most importantly, the political focus has shifted from
individual consumption to collective wellbeing.
These 100
days have changed the way we think about change. Ultimately, whether this
pandemic is good or bad for the environment depends not on the virus, but on
humanity. If there is no political pressure on governments, the world will go
back to unsustainable business as usual rather than emerge with a healthier
sense of what is normal.
For the
French philosopher Bruno Latour, one thing we have learned is that it is
possible in a matter of weeks to slow the economy, which until now had been
considered inconceivable due to the pressures of globalisation.
“The
incredible discovery is that there was in fact in the world economic system,
hidden from all eyes, a bright red alarm signal, next to a large steel lever
that each head of state could pull at once to stop ‘the progress train’ with a
shrill screech of the brakes,” he writes.
This makes
ecological calls to move off a path of endless resource consumption more
realistic, maybe even more desirable. But Latour warns that this unforeseen
pause could easily allow powerful interests to seize more control ahead of the
bigger battles looming over the climate and biodiversity. “This is where we
must act,” he says. “If the opportunity works for them, it works for us too.”
