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 consequences that reach far beyond the future of our water, to many aspects of climate change. They made a case for the creation and resourcing of a federated group of leading modeling centers, linked to dedicated, pioneering exascale computing and data facilities. This sophisticated climate prediction system would serve all nations, providing robust evidence across all aspects of climate change…read more. TECHNICAL ARTICLEÂ
