I am a lecturer in atmospheric science at the University of Leeds specialising in research into stratospheric aerosol and volcanic radiative effects.
Several NCAR scientists played key roles in @wcrpclimate.bsky.social Hunga volcano impacts report, released last week.
The NCAR modelling group (Bill Randel & others) led predictions of ozone layer & climate impacts from Hunga’s volcanic aerosol & water vapour.

This past month showed us once again how extraordinary our weather and climate community is (scroll for 🧵).
Whether you’re joining us as student, scientist, hobbyist, or concerned citizen, let’s #SaveNCAR and put an end to the war on science together 💯

Great to hear a bipartisan group in congress (both Democrat & Republicans) is seeking to secure adequate funding for NCAR in the upcoming Commerce, Justice and Science (CJS) appropriations bill (deadline 31 Jan 2026).

Bipartisan Congressional coalition formally requests continued funding for National Center for Atmospheric Research
Next in series of storm systems into California will likely be most impactful with potential flooding and strong winds through Christmas Eve, while incredible late December warmth spreads east

Pleased to have helped co-ordinate the @wcrpclimate.bsky.social Hunga atmospheric impacts report.
The explosive energy from the VEI6 eruption was likely more than 1991 Pinatubo, on a par with 1883 Krakatau.
Shallow underwater setting saw impacts from emitted sulphur & emitted water vapour.

WCRP’s APARC released a landmark report on global atmospheric impacts of the 2022 Hunga volcanic eruption.
159 scientists. 21 countries. 3 years. One report.
