    Wow, January 2020 was the warmest on record and greater than 3°C above the 1981-2010 climate average in Europe. The average global temperature was also the highest on record. 🔥 More info ():

    Just to reiterate, 2019 was the hottest (and driest) year on record for Australia... 📈 [Data from : ]

    ... well, I won't deny it: I am quite happy and proud, that the data is shown here 😝. Definitely an achievement of our 2019! (EUMETSAT OSI SAF data with R&D input from ESA CCI). (and thanks )

    Nice visualization of how warm (hot) your city will be under different CO₂-emission scenarios and how much it has warmed already.

    This instrument, which at first glance looks a bit like a snow cannon, is a so-called microwave radiometer. With this instrument, Gunnar Spreen from the University of Bremen measures the microwave emission of sea ...

    Your backyard is not representative of global weather/climate. Overall, the average October global air temperature was +1.04°C above 1951-1980 climate baseline (+1.27°C above the 1880-1920 baseline).

    "...there is substantially less ice older than two years old than there used be—about one-third of the amount “old ice” as there was in the mid-1980s and about one-half as much as there was as recently as the mid-2000s." Latest October summary:

    Today, it is formally the end of the set up phase of the ice camp. Almost all the science stations and measurement sites are ready. So most teams will start with time series measurements and sampling wherever possible. 📸 Esther Horvath /

    Large-scale circulation is currently contributing to sea ice drift from the Pacific to Atlantic (see : ). As a result, sea ice extent in the Chukchi Sea is actually decreasing (record low for the date).

    Ridiculous sea ice extent anomalies at the moment (Additional graphs: ) Compared to previous decades: • about 2,300,000 km² less the 2000s mean • about 3,200,000 km² less the 1990s mean • about 3,500,000 km² less the 1980s mean
