Why aerosols matter 🌥️ What happens to our climate if the ingredients of clouds change? That question is asked in a recent paper written by CERTAINTY scientists. 🎤 @drgilbz.bsky.social & @annelev.bsky.social ▶️ www.youtube.com/watch?v=0B6S...

Another PhD defence @UEF Aerosol Physics Group: Irfan Muhammad defending his thesis on modelling aerosol effects on climate. Pontus Roldin (the Opponent) doesn’t let him off easy. And @harrikokkola.bsky.social (the Custos) sweating there in the middle.

Lejish Vettikkat doing excellent job with defending his doctoral thesis on the emissions of biogenic VOCs. Siegfried Schobesberger acting as a custos as a first time (and doing it like a pro!). Prof Steffen Noe is running the show as an opponent. 👌

I agree, we could have stated this clearer. But the value we are referring to, is IRFaci estimate based on observations that is given is the latest IPCC report in section 7.3.3.2.1. We refer to this value because its physical basis is comparable to ours.

Olemme aloittaneet lintujen talviruokinnan. Punatulkkujen ja tali- ja sinitiaisten lisäksi laudan ovat löytäneen myös hömö- ja kuusitiaiset. Melllä on tässä omaa luonnontilaista metsää pari hehtaaria. Jo silläkin taitaa olla vaikutusta pihan lintukantaan?
