I've called this the most important graph in the world.
The only remaining accurate NASA CERES instrument in orbit is on a NOAA satellite.
Your 'moment of doom' for Jan. 21, 2025~ What happens in the Arctic.
"In the permafrost, most of the soils have been entirely frozen throughout the full year. But now the temperatures are warmer, there’s more organic matter available for decomposition, and carbon gets released into the atmosphere."
Without genuine engagement the longevity of initiatives is less likely.
Line graph time series of 2024's daily Arctic sea ice extent compared to decadal averages from the 1980s to the 2010s. The decadal averages are shown with different colored lines with white for the 1980s, green for the 1990s, blue for the 2000s, and purple for the 2010s. Thin white lines are also shown for each year from 2002 to 2022. 2024 is shown with a thick gold line. There is a long-term decreasing trend in ice extent for every day of the year shown on this graph between October and January by looking at the decadal average line positions.
Friday ice update - #Arctic sea ice extent is currently the *lowest* on record (JAXA data) 🧪🔧
• about 410,000 km² below the 2010s mean
• about 1,010,000 km² below the 2000s mean
• about 1,580,000 km² below the 1990s mean
• about 1,900,000 km² below the 1980s mean

Two polar stereographic maps side-by-side showing November 2024 Arctic sea ice thickness and its anomalies, which are relative to 1981 to 2010. Data is from PIOMAS.
November 2024 sea ice thickness was below average across most of the #Arctic Ocean compared to the 1981-2010 average, especially north of Greenland, the Canadian Arctic Archipelago, and Svalbard (right; red shading).

Your 'doom quote' for today:
"The End-Permian extinction was a horrific event, beyond our capacity to imagine. It was mass death by heatstroke."

Your 'bonus moment of doom' for today: We don't need no stinkin' clouds!
"the world’s reflective cloud cover has shrunk in the past 2 decades by a small but tangible degree, allowing more light in and boosting global warming. "

From Carbon Sink to Source? Study published in Nature collect large datasets from tundras around the world, which show how warming could flip these ecosystems from carbon sinks to sources. A large group of researchers using the same methodology worldwide have contributed to a comprehensive study.🧪

Too often ‘impact’ is co-opted to describe how policy makers use our research
True impact for ecologists is to contribute to meaningful nature recovery
Sadly, those 2 aims are not the same
This graphic gives the 12-month running average for Mauna Loa CO₂ since 1959, with a quadratic trendline (in red).
An R² of 0.9995 is overwhelming evidence that atmospheric CO₂ growth is accelerating. And at present, CO₂ is above the trendline!
The climate 8-ball says: "Outlook f&%ked, try again."
Confirmation bias - when examples of colonisation of trees on abandoned land are used to argue for the ubiquity of natural regeneration
but examples of areas remaining largely treeless through dispersal limitation, soil conditions, etc, are ignored
For those who still think that planting trees is a solution to mitigate CO2 emissions, please take note! Forest offset programs can also burn!

Breaking news!

On December 10, Arctic sea-ice extent hit a new modern daily low, beating the previous record daily low set in 2016 by over 155,000 square kilometers.
No ice for you!

The f&%kery continues in the Arctic ... today sea-ice extent is over 300,000 square kilometers below the previous record low for the day.
Absolutely spot on!
Passing through the New Forest today, I’m always surprised that this highly managed landscape is seen as an example of rewilding
Your 'doom quote' for today:
"A species that needs to migrate to keep up with rising temperatures, but is trapped in a forest fragment -- even a very large fragment -- is a species that isn't likely to make it."
www.goodreads.com/book/show/17...
We are likely to be slipping into a terrifying spiral of declines and irreparable damage, but governments seem to be more concerned about short-term economics.
