Science Daily July 25, 2023 The Atlantic meridional overturning circulation (AMOC) is a major tipping element in the climate system and its collapse would have severe impacts on climate in the North Atlantic region. In recent years weakening in circulation has been reported, but assessments by the Intergovernmental Panel on Climate Change (IPCC), based on the Climate Model Intercomparison Project (CMIP) model simulations suggest that a full collapse is unlikely within the 21st century. Tipping to an undesired state in the climate is a growing concern with increasing greenhouse gas concentrations. Predictions based on observations rely on detecting early-warning signals, […]

Predicting rainfall futures
Phys.org June 16, 2022 According to an international team of researchers (UK, USA – Caltech, Germany, Switzerland) the basis around which climate models have been built over the last 30 years misses some fundamental physics that we now know is essential for reliable predictions. The answers exist but a huge joint international investment in resources, expertise, and infrastructure—amounting to an estimated $250 million annually—is urgently needed to develop much more advanced climate models. The current 100 kilometer-scale global climate models should be changed to 1 kilometer-scale models. At these scales, the complex physics of rain-bearing systems is properly represented with […]
