The ice sheets covering Greenland and Antarctica are already melting about six times faster today than in the 1990s. That rate will only accelerate as the planet warms.

The current rate of warming spells doom for 90% of the world's glaciers. Then what?

Antarctic Sea-Ice Update:

As of October 27, Antarctic sea-ice extent is second lowest on record for the day, 3.98 standard deviations below the 1991-2020 average, and about 145,000 km² above the record daily low set in 2023.

Global Mean Sea Level

Global mean sea level rise is caused primarily by two factors related to #GlobalWarming: added water from melting land-based ice sheets and glaciers and the expansion of seawater as it warms.

What is global mean sea level? This is the average height of the entire ocean surface. Global mean sea level rise is caused primarily by two factors related to global warming: the added water from melting land-based ice sheets and glaciers and the expansion of seawater as it warms. What are we looking at? The plot shows global change in sea level since 1993, as observed by satellite altimeters. The black line tracks the measurements, while the blue line shows how much uncertainty is associated with these measurements. Note: The data shown in the plot does not include the glacial isostatic adjustment (GIA). Why do we care? Global mean sea level is an important climate indicator, providing information on how the ocean is warming and how much land ice is melting. Global sea levels have been rising for decades in response to a warming climate. The annual rate of rise – or how quickly sea level rise is happening – has also increased from 0.08 inches/year (0.20 centimeters/year) in 1993 to the current yearly rate of 0.17 inches/year (0.44 centimeters/year). Data on this increase in the rate of global sea level rise is critical to planners understanding the trajectory of future sea level rise. More information on the importance of the 30-year satellite record and data on the trajectory of global mean sea level can be found here. Reference: Willis, Hamlington, Fournier, 2023.

🧊 Tall ice cliffs retreat faster than models say

Measurements show tall ice cliffs calve faster than models assume. Thinning ice stops a runaway collapse, though, which matters for anyone on a coast.

Empirical constraints on ice cliff calving
When calving cliffs at the margins of Earth’s ice sheets exceed a critical height, runaway retreat may be initiated in a process called the marine ice cliff instability. However, sufficiently tall ice...

As of October 13, Antarctic sea-ice extent is more than 5.0 standard deviations below the 1991-2020 daily average.

Under "normal" circumstances, the likelihood of this happening just by chance would be about 1-in-5,800,000.

Also news - 2026 observed the 3rd lowest annual maximum #Antarctic sea ice extent on record. This was reached earlier in the year than average.

Since the maximum, ice extent has rapidly tumbled to close to record low levels for the date!

Antarctic sea-ice extent just set a new record daily low on Sept. 30, beating the previous record set in 2023 by over 15,000 km².

Current extent is 3.85 standard deviations below the 1991-2020 average.

The more you know:

Penguins and polar bears are distant cousins, with a common relative somewhere around 310 to 315 million years ago, a lizard-like creature called an amniote.

Oh, and Antarctic sea-ice extent is now second lowest on record for the date.

Last month saw a very large temperature anomaly gradient between the Weddell Sea region and West #Antarctica. In fact, this was one of the very few places anywhere on the globe with colder than average temperatures in August, especially compared to older baselines (e.g., 1951-1980). Data from ERA5.
Polar stereographic map of 2-m air temperature anomalies in the Antarctic for August 2026. Red shading is shown for warmer anomalies, and blue shading is shown for colder anomalies. There is a lot of variability in the pattern of temperature anomalies across the continent. Anomalies are calculated relative to a 1981-2010 baseline.
