Paris said au revoir to cars. Air pollution maps reveal a dramatic change.
Air pollution fell substantially as the city restricted car traffic and made way for parks and bike lanes.

Potentially no updates to sea ice indices coming from the US for a while... this is horribly damaging to global climate science.
Yes, there are EU and Japanese alternatives to some of these, but multi-dataset inter-comparisons are a critical part of assessing reliability and confidence in the data.

Very nice new tool from @copernicusecmwf.bsky.social. Certainly quite some room for further additions/improvements, but still great to easily share some basic ERA5 stats in no time.
It is also the source of ERA5 data that is used by the new ERA-Explorer: the interactive web-application lets you calculate daily, monthly and annual statistics in seconds clicking on a location on the map.

Astonishing sea ice dynamics north of Greenland at the moment. One of the few occasions (2003, 2011, 2013 and 2018 in the last 25 yrs) of large polynyas opening up in that region during winter. One to watch!
Well, what did I say? Now there is again open water north of #Greenland where the thickest sea ice of the #Arctic used to be. An almost 500 km long lead opened up over the last few days. This is similar to the event in February/March 2018, which resulted in a series of scientific publications.
