…
One the one hand, cutting fossil fuel pollution is necessary for avoiding severe destruction over the long term. But such cuts will make the earth much hotter in the short term.
One recent study cast the well-known declines in air pollution during the COVID-19 pandemic in a darker light.
…
That’s because the shuttered factories and power plants led to a corresponding crash in emissions.
…
After the cuts, the study found that light reaching the surface increased by 7 percent.
…
A draft study led by Columbia University climate scientist James Hansen suggests that the recent rise in temperatures doesn’t come from greenhouse gases at all, but from the reduction in sulfate aerosols since the early-2000s.
…
Not all climate scientists accept Hansen and company’s conclusion.
“I have nothing but respect & reverence for [Hansen] … but I think he is wrong on this one,” University of Pennsylvania climate scientist Michael Mann tweeted.
