Carbon offsets fail to cut global heating due to ‘intractable’ systemic problems, study says Analysis of 25 years of evidence shows most schemes are poor quality and fail to lower emissions

“We must stop expecting carbon offsetting to work at scale. […] We have assessed 25 years of evidence and almost everything up until this point has failed.”

The Greenlandification of Antarctica | Nature Geoscience Climate and ice sheet processes in Antarctica increasingly reflect those observed earlier in Greenland. Applying process insights from Greenland can improve projections of future Antarctic ice and climate behaviour.

Incidentally, the very nice schematic of cryosphere changes over both ice sheets was drawn by @jmalumbresolarte.bsky.social Tak! 🙏

Antarctic Ice Sheet tipping in the last 800,000 years warns of future ice loss - Communications Earth & Environment The Antarctic Ice Sheet exhibits hysteresis and irreversible ice loss, with West Antarctic collapse contributing over 4 m of sea-level rise even under minimal additional warming, according to 800,000-...

Simulations covering 800,000 years show that a slight deep-ocean warming can trigger West #Antarctic Ice Sheet collapse, raising sea level by about 4 metres.

Today’s temperatures are already at this threshold. Future irreversible ice sheet loss may occur with little/no further climate warming.

🧵🧪🌊 According to the @nsidc.bsky.social sea ice index #Antarctic sea ice extent peaked this year on 15th September at more than 17.8 million km².

From a poster called “just shower thoughts“ reading: when people talk about traveling to the past, they worry about radically, changing the present by doing something small, barely anyone in the present to really thinks that they can radically change the future by doing something small.

I may have found my defining quote.

Pair this with my pinned post and you will see what I mean!

Alpine glaciers are melting even on the highest peaks Swiss glaciers have lost a quarter of their volume in 10 years. Climate change is accelerating melting even at high altitudes

“This year turned out to be a little less extreme than we feared", says Matthias Huss, director of GLAMOS. “However, what worries me is that we’re getting used to these very negative years. It’s a new normal, but one that shouldn’t be there.” @matthias-huss.bsky.social @vaw-glaciology.bsky.social

AI Overview: "Dental realism"refers to the philosophical debate about whether teeth exist independently of human perception, a concept rooted in metaphysical realism. While realism asserts an objective reality for teeth, idealist philosophies contend that teeth's existence is tied to our consciousness and perception. Philosophers use this idea, for example, to discuss the ethics of tooth extraction, examining whether a procedure impacts a real entity or merely a subjective experience.

deforestation *caused primarily by cows and soy for factory farmed animals* reduce rainfall in the amazon.

this is why meat is not just a moral issue but a political-ecological issue that reshapes out climate and environment and biodiversity in profound and irreversible ways.

Shocking stats from this paper on the extreme 2024 summer heat in Arctic Svalbard, which lost 1% of its total ice volume in just ~6 weeks. 🔥

In fact, Svalbard's 2024 glacier mass loss actually exceeded that of the Greenland Ice Sheet, which is 50 times larger!!! 😱

Calving-driven fjord dynamics resolved by seafloor fibre sensing - Nature Iceberg calving can act as a submarine melt amplifier through excitation of transient internal waves.

🌊 Icebergs shake the sea as they break away

A new study using seafloor fibre sensing shows that calving glaciers trigger waves and currents that accelerate submarine melt, reshaping fjord dynamics and sea level rise.

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 May and August by looking at the decadal average line positions.

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

• about 350,000 km² below the 2010s mean
• about 1,010,000 km² below the 2000s mean
• about 1,590,000 km² below the 1990s mean
• about 2,150,000 km² below the 1980s mean

We talk a lot about the level of climate warming, have we passed a given threshold, and less about the rate. The rate is the core problem: we are changing climate faster than society or the environment can adapt. If it took 10,000 years to warm by 2 C, this would be a different conversation.

"Instead, talk about why you care about climate change. How is it affecting the people, places, or things you love? Share the small victories—yours and others’—and celebrate them. Use your voice to advocate for change where you live, work, study, or worship."
