CCSR has a unique standing at Columbia University. It is one of only a few centers in the United States actively developing a global climate model to understand past and future climates both on Earth and on other planets. To do so, we have a special relationship with NASA. We are co-located with the NASA Goddard Institute for Space Studies in Columbia’s Armstrong Hall. Here, Columbia and NASA scientists work closely together to advance climate science and improve societal resilience to climate-related challenges both in the United States and around the world. CCSR scientists and staff also work with many other partners – private sector, governmental, and non-governmental organizations – to answer these challenging scientific, social, and economic questions.
