I have never seen the urgency to fly to as many distant (mostly climate-related!) conferences as possible to the detriment of our personal and our planet’s health. COVID-19 should have taught us that we don’t need to.
I do atmospheric sciences research (PhD 1988), primarily related to stratospheric dynamics and transport, Arctic ozone loss, relationships of the stratospheric polar vortex to the tropospheric circulation and to extreme weather.
