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

A new reconstruction by Professor Bob Hilton and colleagues from Oxford Earth Sciences has shown that chemical weathering can contribute to global warming. The study, published in Nature Communications, demonstrates that weathering of carbon-rich sedimentary rocks can release carbon dioxide to the atmosphere, and confirms that this contributed to rising temperatures in the Early Jurassic, 183 million years ago. This important new study highlights an overlooked climate mechanism that may have also been active in other periods of geological time.
