This is unsurprising to me. Global heat retention changes are mostly due to changes in the concentration of atmospheric greenhouse gases. While the rate at which those greenhouse gases is added has dropped due to the economic effects of the pandemic, the absolute concentration of greenhouse gases is still increasing. Combined with the destabilization of the polar vortex, I anticipate the ice melt rate to continue to increase.

What we've done is reduce the pressure with which the accelerator is pushed to the floor of the car, but it hasn't had time to spring back up yet and close the throttle. FWIW: people were warning about this control problem (and even using that very metaphor) back in the 1980's.
- joshspankit 6y agoAre we even at “zero throttle” now? Or have we gone from 150mph to 45?
- s1artibartfast 6y agoCO2 is the second derivative of temp, so it is equivalent to acceleration, so the speed is still going up. distance = Industraly caused temperature difference speed = Co2 Acceleration = Co2 emissions. There are no realistic IPCC models where the car starts to coast or decelerate before 2100. https://www.carbonbrief.org/explainer-the-high-emissions-rcp8-5-global-warming-scenario https://www.carbonbrief.org/explainer-the-high-emissions-rcp...
