Melt ponds are visible on satellite (blue shading) across much of the landfast sea ice along Siberia; e.g., in this image above the Lena River Delta.

🧵 While extreme events receive a lot of the attention in the #Arctic, it's more the long-term trends that are transforming this part of the world. Interannual variability (e.g., weather) is also large, which is why not every year is a new record. Here are those January trends:
Nearly all areas of the #Arctic have observed thinning ice over the last four decades. Trends in January are largest in the vicinity of the East Siberian Sea and north of Greenland.

[Data simulated from PIOMAS. For more info: doi.org/10.1175/JCLI-D…] Polar stereographic map of Arctic sea ice thickness trends f
In contrast, sea ice concentration trends in January are only confined to the outer edges of the #Arctic Ocean, such as the Barents-Kara Seas and Sea of Okhotsk.

Over the last 5 years, there have been plenty of extreme weather/climate events in the #Arctic. While the scientific process takes time, there are now lots of studies investigating these cases. Please add to this thread with other peer-reviewed studies on recent Arctic extremes!

🚨 2019 was the 2nd warmest year on record - @CopernicusECMWF analysis. An excellent summary is provided at climate.copernicus.eu/copernicus-201…

While 2019 rankings between various data sets may differ slightly (e.g., 2 or 3), the long-term warming is undoubtedly clear... Line graph time series of running mean global temperatures for various data sets
🚨 Last year's #Arctic sea ice extent averaged the *2nd lowest* on record. Sea ice is declining in all months of the year (iopscience.iop.org/article/10.108…).

Check out @NSIDC's annual/decade summary: nsidc.org/arcticseaicene…
🚨 #Arctic sea ice volume in 2019 also averaged the *2nd lowest* on record (albeit close to the last few years).
