You’ve heard about Antarctic sea ice lows - well, here’s the consequences.

Over 9,000 emperor penguin chicks from colonies in the Bellingshausen Sea are thought to have died in November 2022.

The sea ice they lived on broke up early, before they'd developed waterproof feathers.

Record high melt event for this time of year is currently ongoing over the Greenland Ice Sheet...

Due to unusually low sea ice in both poles (especially the Antarctic), global sea ice levels continue to remain well below the previous satellite-era record for late August...

Latest 'cloud-free' mosaic from MODIS satellite imagery showing the lack of #Arctic sea ice and thus greater areal coverage of open water (compared to past decades). Note also the large phytoplankton bloom and drifting wildfire smoke.

Simulated reconstruction of August #Arctic sea ice thickness since 1901. Interannual variability and an obvious decrease in recent years.

Information about this data set is available at doi.org/10.1175/JCLI-D…. Note that it is only updated through 2010 due to ERA-20C forcing.

Last month observed the largest temperature anomalies across the tropics (El Niño) and Northern Hemisphere midlatitude region...

Same situation for the Southern Hemisphere mean - record hot July too

This 'ensemble boosting' approach is a really helpful way of demonstrating what a 'worst-case' weather event might look like for a particular region.
It also shows that climate models can reproduce the size of recent record shattering extremes in the current climate.

The climate dashboard and dashboard of dashboards dashboard has a new dashboard or two. Zack Labe's amazing webpage and the @UCL Climate change in numbers page.

100 years of average May to July temperature anomalies over land areas - there is relative warmth practically everywhere by the end of the animation.

#Arctic sea ice extent is currently the 6th lowest on record (JAXA data)

• about 3,000 km² below the 2010s mean
• about 1,020,000 km² below the 2000s mean
• about 2,010,000 km² below the 1990s mean
• about 2,680,000 km² below the 1980s mean

Less than a year ago Twitter was the best source of on-the-ground reports during a disaster. Now searching for anything related to Hilary just produces an incomprehensible pile of fake videos and claims, all laundered to the top of search results with meaningless blue checks

Trends in August air temperatures show greater warming around the perimeter of the #Arctic Ocean, especially in the Kara Sea, Laptev Sea, and Canadian Arctic Archipelago regions.

Join me in tracking this year's #Arctic sea ice minimum!

Sea ice melt substantially slows every September as solar energy decreases and temperatures drop.

No new records are likely this year for the minimum. Follow along at zacklabe.com/arctic-sea-ice…

July 2023 data is now available from GIOMAS for Antarctic sea-ice thickness/volume (zacklabe.com/antarctic-sea-…) and global sea-ice volume (zacklabe.com/global-sea-ice…).

Last month's temperatures across the Northern Hemisphere were not even close to the previous record.

One area of the #Arctic observing unusually low sea ice is across the Canadian Archipelago region, which is at record low levels for this time of year...
