Wildfires in Australia in 2020 produced a massive increase in stratospheric aerosols in the Southern Hemisphere.

Intense, widespread bushfires in Australia injected huge amounts of smoke into the stratosphere in 2020. Hirsch and Koren found that this smoke caused record-breaking levels of aerosols over the Southern Hemisphere, as much as that from a moderate volcanic eruption. The severity was caused by a combination of the vigor of the fires and their location at a latitude with a shallow tropopause and within the midlatitude cyclones belt. This aerosol increase caused considerable cooling over oceanic cloud-free areas.

All your COVID-19 vaccine questions answered, and a new theory on forming rocky planets

Sarah also talks with Anders Johansen, professor of planetary sciences and planet formation at the University of Copenhagen, about his Science Advances paper on a new theory for the formation of rocky planets in our Solar System. Instead of emerging out of ever-larger collisions of protoplanets, the new idea is that terrestrial planets like Earth and Mars formed from the buildup of many small pebbles.

Two Years Ago, Florida Gov. Ron DeSantis Was Praised for Appointing Science and Resilience Officers. Now, Both Posts Are Vacant.

When Florida Gov. Ron DeSantis took office two years ago in a state that had been hammered by two major hurricanes in two years and was suffering through an epic toxic algae crisis, he earned widespread praise for appointing the state’s first chief science and chief resilience officers.

Julia Nesheiwat, the resilience officer, left early last year after only several months on the job, accepting a position as President Donald Trump’s homeland security advisor.’

Now, the DeSantis administration has acknowledged it no longer has a dedicated chief science officer, either.
