A biennial report released April 1 by a team of experts that advises California’s governor suggests that climate changes are poised to affect virtually every sector of the state’s economy and most of its ecosystems. Significant impacts will likely occur under even moderate scenarios of global greenhouse emissions and associated climate change, but without action, severe and costly climate change impacts are possible across the state.
The state Climate Action Team (CAT) report uses updated, comprehensive scientific research to outline environmental and economic climate impacts. Its authors include Dan Cayan, a climate scientist at Scripps Institution of Oceanography, UC San Diego, and a member of the CAT steering team.
A broad collaboration of scientists, mostly from state academic and government agencies, provided a large set of technical papers that form the underpinnings for much of the CAT report. Assessments include the impacts of sea level rise, higher temperatures, increased wildfires, decreased water supplies, increased energy demand, among others, on the state’s environment, industries and economic prosperity. Each of the papers has undergone peer review by technical experts in private, public and governmental entities.
Impacts of climate change to California’s coast, agriculture, forest and communities have been known and studied for years; however the studies that support the CAT report suggest that actual greenhouse gas emissions are outstripping 2006 projections. Of particular interest are the several papers focusing on the impacts of a rise in sea levels to coastal communities and increased potential of wildfires to residential areas.
“The Climate Action Team plays an essential role in the implementation of the state’s climate initiatives and is guided by these important technical studies to ensure policy decisions are based on sound science,” said Linda Adams, Secretary for Environmental Protection and Chair of the state’s CAT. “Any delay in fighting global warming would be detrimental to our economic stability – costing us billions of dollars and dampening the state’s most important economic sectors. Taking immediate action on climate change is essential to slow the projected rate of warming. We also need to make smarter decisions in order to anticipate and adapt to the changes.”
