James Hansen Study Ends ‘Consensus’ -- COVID Shutdowns Blow Lid off Global Warming Theory

Climate paradox: Emission cuts could ‘unmask’ deadly face of climate change, scientists warn

The Hill June 2, 2023 (excerpt): … The pandemic-era economic slowdown led to “a large-scale geophysical experiment,” study leader Örjan Gustafsson of Stockholm University said in a statement.

That’s because the shuttered factories and power plants led to a corresponding crash in emissions….

for all the damage they do to human lungs, aerosols also help shade the earth by scattering light particles from the sun that would otherwise warm the planet.

After the cuts, the study found that light reaching the surface increased by 7 percent.

“While the sky became bluer and the air cleaner, climate warming increased when these cooling air particles were removed,” Gustafsson said.

While aerosol concentrations fell as the smokestacks shut off, other gases remained stubbornly high.

In particular, levels of the most potent climate-warming gases — like carbon dioxide — barely changed.

Carbon dioxide and other greenhouse gases warm the planet by trapping heat. The combination of more heat hitting the same amount of carbon dioxide meant a straightforward rise in temperatures.

The sudden rise in temperatures led by the pandemic reduction is a stark example of a more general problem — one that has long haunted the drive to cut pollution.

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….
