We've been delighted to host Gisela Winckler from Lamont-Doherty Earth Observatory of Columbia University, USA, as our visiting guest scientist over the last few weeks.
Gisela is the Co-Chair of our DICE working group, a group that addresses dust's impact on climate and environment. She has been busy progressing plans for the group's transient database, a resource designed to help us understand the link between aerosols, climate, dust, and circulation by synthesizing paleo reconstructions and modern observations. In addition, she's been making plans for the first DICE meeting, to be announced in the coming weeks.

After more than four years of virtual collaboration, our Ocean2k Working Group has published a study in Nature Geoscience showing an 1800 year-long robust cooling trend in global sea surface temperatures. They link the coolest period, between 801 to 1800 CE, with an increase in volcanic eruptions. From the 1800s onward, the cooling trend stops and a statistically significant warming is seen, likely due to human-caused global warming.
This study is the missing ocean component to the PAGES 2k Consortium's 2013 Nature Geoscience study into land-based temperatures over the last 2,000 years.
