Global Warming is taking a rare back seat in the news right now, as we deal with the more immediate existential crisis afflicting our civilisation and way of life. But as entire countries are getting shut down around the world, with the rapid reduction of emissions that this causes, is the global dimming paradox about to be tested? Will we see an abrupt spike in temperatures that tips our earth systems into an irreversible cascade of warming feedbacks?

   

I am quite curious about the temperature fluctuation we might be experiencing right now. I recall after 9/11 that the reduction in worldwide air traffic reduced pollution in the upper atmosphere, as well as the cloud cover seeded by contrails, and world temperatures for those days saw a higher daytime high and lower overnight low.

Just speaking for my own experience in California it's been cooler than average since January 1st and by around 10F per day. Only this week are we starting to get near to our seasonal averages.
