We're seeing a significant, rapid warming of the water basins near the Pine Island Glacier & the Totten Glacier. This could lead to very rapid, noticeable accelerations in the glacier tongues.

Hopefully, world leaders will begin to understand.
It's actually quite simple.
Doing nothing is murder. The murder of billions of people.
Meanwhile, all permafrost regions on Earth have become sources of CO₂ and our rainforests have become emitters, not CO₂ absorbers, since the coronavirus pandemic.

Just to point out that the sleeping giant, until now, is starting to warm up a bit too quickly for my liking.
We're seeing strong interseasonal increases in atmospheric temperatures above the ice shelves & sea ice, as well as in water temperatures beneath the sea ice, ice shelves & glacier tongues.

The median date for global sea-ice extent to hit its annual maximum is November 2nd. That was yesterday.
It's looking like 2025 may end up with the second lowest global sea-ice maximum since records began in 1988, behind only 2024. And 2016 is just barely higher.
Stay tuned!

We see this phenomenon in both hemispheres, and that is the most disturbing.
The poles should be responsible for cooling & stabilizing our climate.

We may (read: must) state that the most important tipping point of our entire climate system (that of the Southern Ocean) has now been reached.
Sea ice hardly grows back in winter anymore. We see very thin sea ice at both poles. Only a few dozen centimeters compared to several meters ten years ago.

This is what the end of the eight-month global warming hiatus looks like in figures and graphs. However, there is no plateauing or leveling off of the trend. On the contrary, the warming trend will steepen due to the accelerated warming of the ocean surface.
