Not Just a Carbon Sink: Weathering Found to Drive Ancient Global Warming

👀 Organic carbon weathering as an amplifier of climate warming 183 million years ago: “Weathering of sedimentary carbon-bearing rocks, such as shales, can emit significant quantities of CO2, causing temperatures to rise and further weathering to occur” ⚒️🧪

Not Just a Carbon Sink: Weathering Found to Drive Ancient Global Warming

New research from @profbobhilton.bsky.social has shown that chemical weathering does not always stabilise rising temperatures in the geological past, and that weathering of carbon-rich sedimentary rocks reinforced warming during the Early Jurassic 🌍

Global glacier mass change in 2025 - Nature Reviews Earth & Environment Glaciers lost 408 ± 132 Gt of mass during the hydrological year 2025, equivalent to 1.1 ± 0.4 mm sea-level rise. Since 1975, glacier mass loss has totalled 9,583 ± 1,211 Gt, equivalent to 26.4 ± 3.3 m...

Glaciers had one of their worst years in 2025:

👉 408 billion tonnes of ice mass lost
👉 ≈1.1 mm added to global sea levels
👉 6 of the 7 worst years have happened in the past 7 yrs

Since 1975: ~9,600 billion tonnes gone (≈26.4 mm SLR)

This isn’t a gradual change...

Our perspective on ERW -Uncertainties of enhanced rock weathering for climate-change mitigation- was featured in the New Scientist

Here is the paper: www.nature.com/articles/s43...

Earth's heat to produce electricity for homes in UK clean energy first Water super-heated by rocks will also provide the UK's first domestic supply of the critical mineral lithium.

Great news from #Cornwall, where #geothermal energy and lithium are now being generated from deep, hot granite. ⚒️

Is enhanced rock weathering ready as a climate mitigation strategy?

Our latest work explores key uncertainties — from feedstock availability and the land–ocean continuum to plant–soil interactions and socioeconomic impacts.

Ancient global warming was amplified by widespread forest fires and soil erosion 56 million years ago the Paleocene-Eocene Thermal Maximum (PETM), a period of rapid global warming, occurred. Within the span of a couple of millennia, temperatures rose by 5 degrees, triggered by a huge release of carbon. Due to its likeness to present-day warming, the PETM is often used to test the long-term environmental response to large-scale perturbations, making it a very scientifically valuable climatic event to study.

New research shows that global warming during the Paleocene-Eocene Thermal Maximum was amplified by widespread forest fires and soil erosion, which occurred within as little as a few centuries after a huge amount of carbon dioxide entered the atmosphere 🔥
