  2. Temperatures over land have warmed approximately 2x as fast as ocean surface temperatures. The 2019 mean global temperature was about 1.2°C (2.2°F) above pre-industrial levels (1880-1920). [Graph available from ]

  4. 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 ():

    sea ice extent is currently the 13th lowest on record (JAXA data). • about 260,000 km² above the 2010s mean • about 370,000 km² less the 2000s mean • about 940,000 km² less the 1990s mean • about 1,360,000 km² less the 1980s mean More plots:

    Average January sea ice extent was statistically tied for the 8th lowest on record. This was 770,000 km² below the 1981-2010 average. January ice extent is decreasing at 3.15% per decade (satellite-era). Data from .

    Bering Sea extent up to about 87% of 1981-2010 average for the start of February in data. Stormier weather pattern already underway for the region. This is likely to slow growth & modify ice distribution in the coming week.

    At first glance it may look noisy, but if you look closely you can learn quite a lot about the transport of moisture around the world (e.g., convergence zones, monsoons, seasons, land-sea contrasts) [Data from ERA5(T) ---> weekly TCWV in 2019]

    Air temperature anomalies exceeded +5°C (relative to 1951-1980) over the Chukchi Sea in 2019 (). Unsurprisingly, this coincided with widespread open water (less sea ice cover). Data from .

    sea ice extent only expands in the very outer marginal seas by this time of year. For example, look at the sharp seasonal cycle in the Sea of Okhotsk (western Pacific). This year is running close to average in the region. Data from .

    Nature just published a comment by and I pointing out that the high-emissions RCP8.5 emissions scenario – with its 500% increase in coal use by 2100 – is increasingly unlikely in a world of falling clean energy prices. A thread: 1/11
