Climate change and its effects
are possibly the most important story of our time
The
Guardian - Global heating made hot, dry and windy weather at least 20
times more likely in Spain and twice as likely in France, experts from the
World Weather Attribution (WWA) consortium calculated. The finding is the
latest to pin the blame for the continent’s sweltering and deadly summer firmly
on the heating caused by the burning of oil, gas and coal.
The intense heatwave at the end
of June, which is estimated to have killed 20,000 people, could not have
happened without the extra heat trapped by carbon pollution, a previous WWA
study showed. Another found that the climate crisis-driven heat was “sucking
soils dry” as extreme drought spread across Europe…
This year’s wildfires in western
Europe have been made worse by a wet winter and spring, which boosted the
growth of vegetation, which then dried out and provided fuel for the fires –
so-called whiplash conditions. Global heating is making winters wetter and
summers drier and hotter in Europe.
Dr Clair Barnes, a research
associate at Imperial College London and part of the WWA study team, said:
“We’ve seen repeatedly how climate change increases hot, dry, flammable
conditions that are extremely conducive to wildfires.
“What’s unique about [the July
fires in Spain and France] is that it’s still early in the season – and with
another heatwave looming, these findings are extremely scary. What we’re seeing
is a clear sign of the escalating impacts of [human-caused] warming.”….
The wildfires have released huge
plumes of toxic smoke. Dr Augustin Colette, at the French National Institute
for Industrial Environment and Risks, said: “The smoke increased particulate
[pollution] peak levels up to 20 times above what is considered ‘fair air
quality’, and extremely poor air quality was felt up to 400 km away from the
fires.” About 1.5 million people a year are estimated to have their lives
shortened by wildfire smoke.
….The UN’s climate chief, Simon
Stiell, said: “These European megafires show how fast climate-driven extreme
heat and dry landscapes can turn wildfires into devastating national disasters.
“Humanity continuing to burn colossal amounts of coal, oil and gas is making
these conditions more dangerous, and these megafires more deadly and
destructive,” he said. “But the solutions are equally clear: all countries must
move faster from fossil fuels to renewables and protect people from worsening
climate impacts, from wildfires, to megastorms and floods, to droughts hitting
food production.”
