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.

Awful. More horrible science news "The NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) learned yesterday that the Department of Defense (DoD) will stop processing & delivering the Special Sensor Microwave Imager/Sounder (SSMIS) data no later than 30 June 2025."
Screenshot from NSIDC that says: "Dear Colleague:

The NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) learned yesterday that the Department of Defense (DoD) will stop processing and delivering the Special Sensor Microwave Imager/Sounder (SSMIS) data no later than 30 June 2025. The SSMIS data are used as input for the following NSIDC DAAC-produced data sets, which will therefore stop processing no later than 30 June 2025:"

What happens in the Arctic doesn't stay in the Arctic. It affects us all. The Arctic Monitoring and Assessment Programme (AMAP) has released their Summary Arctic Climate Change Update. Read it: www.amap.no/documents/do... Nobody can later say they weren't warned, again and again.

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.

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!

The waters surrounding sea ice in the #Arctic remained warmer than average across nearly all areas in December. Some of the largest anomalies were found across the southern Barents Sea region. Data: NOAA OISSTv2.1 (www.ncei.noaa.gov/products/opt...) 🌊
Polar stereographic map showing sea surface temperature anomalies in December 2024 relative to 1982 to 2010. Most areas are warmer than average. Sea-ice cover is also shown if sea-ice concentration is at least 15% per each grid point. Red is shown for warmer sea surface temperatures, and blue is shown for colder sea surface temperatures. Data is from OISSTv2.1.
