Monday ice update - #Arctic sea ice extent is currently the *2nd* lowest on record (JAXA data)

• about 770,000 km² below the 2010s mean
• about 1,390,000 km² below the 2000s mean
• about 2,010,000 km² below the 1990s mean
• about 2,530,000 km² below the 1980s mean

Line graph time series of 2025'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 purple for the 1980s, blue for the 1990s, green for the 2000s, and white for the 2010s. Thin white lines are also shown for each year from 2000 to 2024. 2025 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.

I’ll say it—I don’t think COP30 went very well

Meanwhile, even the people ostensibly on the right side of the issue can't find right words. "We are not fighting fossil fuels, we are fighting the emissions from fossil fuels," said European Commission President Ursula von der Leyen said at a press conference last week, in a feat of absurdism. This is like fighting gun violence by saying the real villain is gunshot wounds. She said this just a day after a literal fire broke out inside the pavillion at COP30, prompting a full evacuation and sending 13 people for treatment for smoke inhalation and some mirthless deity straight to metaphor jail.

🏔️ Research from Scripps Oceanography scientist Lia Siegelman finds undersea "storms" are melting Antarctic glaciers from below. Researchers also identified a positive feedback loop in which ice shelf melting caused more ocean turbulence, which in turn caused more ice shelf melting.

It's a powerful feedback loop: more ice shelf melting changes salinities which generates more ocean turbulence, which in turn causes more melting — with major implications for ice shelf stability and global sea level rise. (arrow shows max melt ratio)

Eruption of the Hunga Tonga–Hunga Haʻapai in 2022 was a unique phreatic eruption even where we can learn many things on the effects of explosive eruptions on the Earth system.
Eruption was so large that in the atmosphere formed transient ice ring.

Why microplastics should be routinely sampled by limnologists.

No environmental field survey that has searched for microplastics has yet failed to detect their presence. They are omnipresent in the water column, in the sediments, and in aquatic food webs.

The findings of a study in Nature Climate Change show that artificial light at night disrupts the fundamental energetic constraints on ecosystem metabolism, warranting the inclusion of light pollution in global change and carbon–climate feedback assessments. go.nature.com/44cCKWm 🧪
This is figure 1, which shows distribution of flux tower sites across artificial light intensity in North America and Europe.

📢Global Carbon Budget 2025📢

Fossil CO2 emissions continue to rise in 2025 while the terrestrial carbon sink recovers to pre-El Niño strength.

The key findings are covered in two reports this year:
