What processes have regulated climate over the course of Earth’s history? Researchers are addressing this question in the face of anthropogenic climate change. Dr. Dominik Hülse of MARUM – Center for Marine Environmental Sciences at the University of Bremen, and Dr. Andy Ridgwell of the University of California (USA) have uncovered a previously missing part of the puzzle in describing the global carbon cycle and climate regulation. In a new issue of the professional journal Science, they introduce an expanded Earth System model that shows how global warming can be overcorrect into an ice age.
In July 2024, a 7.4-magnitude earthquake struck Calama, Chile, damaging buildings and causing power outages. A sequence of events, discovered by researchers at The University of Texas at Austin, helped supercharge its strength. In a recent study in Nature Communications the researchers describe the chain of events that was responsible for increasing the earthquake’s intensity.
