Climate and population changes would expose millions more to severe flooding in continental U.S.

Q&A with expert Eric Fournier who explains why the architecture of California’s grid isn’t well suited for such extreme conditions and what it would take to improve it.

Warmer temperatures will increase rainfall during heavy wintertime precipitation events and reduce snowpack that usually melts throughout the spring and summer.

25 years after the Northridge earthquake, researchers are using the latest information and technology - including accelerometres, artificial intelligence, machine learning, Google Earth, and international databases - to understand and manage earthquake risks in both California and more widely across the United States.

New research projects that the state of California will experience a much greater number of extremely wet and extremely dry weather seasons — especially wet — by the end of the century. The authors also predict that there will be a major increase in the likelihood of severe flooding events, and that there will be many more quick changes from one weather extreme to the other.

This report provides information on future projections of climate change and its impact in California's Sierra Nevada, including on its snowpack and subsequent water resources. The study employed hybrid downscaling, a combination of global climate models

Programs in which people pay landholders to support natural systems that provide benefits like flood protection, biodiversity and carbon storage, are expanding around the world. A new study identified more than 550 programs active worldwide, in both developed and developing countries, with more than $36 billion in annual transactions.

This report outlines a project to track the recovery of residential building stock following the 2014 Napa, California earthquake. Results demonstrated that recovery is significantly influenced by pre-existing socio-economic factors, which should be
