L'ultima volta avevamo parlato della reazione di Urey e di come questa sia intimamente connessa con il termostato geologico della Terra: il weathering dei silicati. In questo episodio parleremo invece di cosa succede quando il termostato si inceppa in modalità Ice Age.

✨Year-end office clean-up and we found a hard copy of the IGBP Newsletter (1990) revealing the very beginnings of PAGES 🐣
💡Did you know PAGES was first proposed as an IGBP core-project called “PaGloCha”? More than 30 years later, PAGES is still going strong thanks to the #paleoscience community!

Looking back over the last 12 months, all latitude bands observed above average temperatures. This was largest in the Arctic region.
Plot shows zonal-mean surface air temperature anomalies, where latitude = x-axis (not scaled by distance). Data from NASA GISTEMPv4 (1951-1980 baseline).

Early instrumental climate reconstructions (pre-1850) struggle with sparse measurements and have large uncertainties.
But they do provide some insights into a particularly interesting period.
Four major volcanic eruptions occurred 1780-1840, each larger than anything since.

As the ice cap forms, it traps air bubbles, which then remain isolated. It has allowed us to reconstruct our past climate of 800,000 years ago. This was the date of the oldest Antarctic ice sampling thanks to a ice core drilled near the base of the Antarctic ice sheet.

Notice the data source in the bottom right: NASA JPL. This is the type of space climate science Trump is illegally dismantling.
We built insanely complicated satellites, operated them for years, discovered in detail how the ice caps are melting, and our response as a country is "who cares."

In summary, the outlook is grim. It is highly likely that Thwaites Glacier will eventually be lost, which will destabilise adjoining parts of the West Antarctic Ice Sheet, increasing the committed long-term rise in global mean sea level by more than 3 m.

September 2025 was the third warmest on record in the Berkeley Earth dataset. But this downplays how anomalous it was; without 2023 and 2024 this year would have been well above any prior records and well above the long-term trend:
