NASA’s iconic Goddard Institute for Space Studies—home to Jim Hansen and hundreds more scientists, creator of the GISS model and keeper of the global temperature record—has been evicted from its longstanding NYC office above the “Seinfeld” restaurant. Why? The government told them to move out.

For the first time, I'm heading to EGU this year (and after, the WCRP meeting). Will anyone else be there that wants to talk IGAC? We should connect if so!

New: A NOAA lab in Hawaii that is connected to the longest-running observation of global greenhouse gas concentrations is slated for closure in August, according to a list of lease terminations Democratic members of Congress shared with @washingtonpost.com.

The lab is connected to the Mauna Loa Observatory, where scientists gather data to produce the Keeling Curve, a chart on the daily status of atmospheric carbon dioxide concentrations.

If you have the chance to join a @faradaydiscussions.rsc.org conference, do it! It's an excellent event, where submitted papers are discussed lively and in detail by renowned scientists. I loved it and learned a lot!

Day 2 of @faradaydiscussions.rsc.org on *Atmospheric Chemistry in Cold Environments* in full swing. Cool concept: Fresh & new publications are intensively discussed & comments/questions of the expert audience are published together with the final publication. #CATCHscience

By definition, numerical weather models require international data. The atmosphere knows no geopolitical boundaries: any model that begins and ends at its country’s border is unable to generate reliable predictions until after a weather system crosses its boundaries. Which defeats the purpose!
