How Will Climate Change Affect Northern California?


Forest and rangelands cover over 80% of California’s 100 million acres. Climate change will affect tree survival and growth, reducing these lands’ productivity and changing their habitats. In addition, climate change makes forests more vulnerable to fires by increasing temperatures and making forests and brush drier.
