California’s Fifth Climate Change Assessment warns of profound disruptions, projecting significantly hotter temperatures, longer summers, and more extreme weather. Temperatures are expected to rise by about 4 degrees Fahrenheit by mid-century, with summer lasting 135 days compared to the historical 90-day average. This prolonged heat will increase wildfire risks, reduce Sierra Nevada snowpack by 40 percent, and threaten water supplies, agriculture, and tourism.
The report highlights that the state has already experienced these shifts, logging its warmest August and suffering destructive wildfires. Abby Edwards, senior deputy director for the Governor’s Office of Land Use and Climate Innovation, said the assessment aims to guide communities and decision-makers. The report presents multiple scenarios based on future greenhouse gas emissions.
As the federal government rolls back environmental protections, California continues to assert its climate leadership. Governor Gavin Newsom stated that while the Trump administration turns its back on science, the state is doubling down on climate action. The assessments, initiated in 2006 under Arnold Schwarzenegger, remain crucial tools for addressing global warming's localized impacts.
