"I wrote a book eight years ago. I consider myself politically an anti-fascist - I detest fascism... I’m a professor. I’m just trying to live my life here. Because the far right is trying to create a bogeyman term in “antifa” to equate protests with terrorism, I got caught up in the middle of this."

"The vast accumulation of evidence shows that the human impact on Planet Earth has attained geological scale. We have become an ‘event’ with the destructive force of a supervolcano or large asteroid impact, but one that appears to be happening in slow-motion in terms of our own limited perceptions."

"Many religions have attempted to make statues of their gods very large, and the idea, I suppose, is to make us feel small. But if that's their purpose, they can keep their paltry icons. We need only look up if we wish to feel small."

Record high temperatures are currently being set across the northernmost portions of the #Arctic. In fact, it is effectively ice-free on the Atlantic side of the Arctic all the way up to about 85°N latitude! This includes record low sea ice around Svalbard.

Line graph time series of 2025's daily 2-m temperature in the Arctic compared to each year from 1958 through 2024. There is a long-term warming trend for every day of the year. There is also large interannual variability and a clear seasonal cycle.

"That this is false would be apparent to most first graders. Yet this is, in effect, what Donald Trump wants us to believe when he tells us that the United States is in the midst of an “insurrection” and that there is an “invasion from within” that requires US troops to quell."

A reminder to those who wonder at the cruelty, lack of moral justice & steely determination of the current administration that their methods come from a deeply religious zealotry.

October has observed some of the largest warming trends in the #Arctic. This is greatest over areas with a lack of sea ice cover (nearly all of the Siberian Arctic). Arctic amplification is largest in the boreal fall.

Data: doi.org/10.24381/cds.... Info: doi.org/10.1175/BAMS....
Polar stereographic map of 2-m temperature trends in units of °C per decade over the Arctic for the month of October. Trends are calculated over the 1979 to 2024 period using ERA5. The largest warming is an areas of open water that were previously sea ice covered along the Siberian side of the Arctic. These trends exceed 2°C/decade in these areas.

Antarctica may have passed a climate tipping point of no return, scientists are warning, with mounting evidence that a sudden slump in sea ice formation since 2016 is linked to human-induced ocean warming.

Happy October! 🍂 Like other times of year, our planet is heating up this month… but some regions warm faster than others. Arctic amplification especially ramps up in October.

Maps show the changes in October temperature over the last 4 decades. Data used from @copernicusecmwf.bsky.social ERA5.
Four global maps showing near-surface air temperature anomalies for the month of October in 1985-1994, 1995-2004, 2005-2014, and 2015-2024. Most all areas are observing long-term warming, which is largest over the Arctic region and Asia. Anomalies are calculated relative to 1951-1980 from ECMWF ERA5 reanalysis.
