According to a new website launched by the California office of Planning & Research, climate change poses an immediate and growing threat to California’s economy, environment, and to public health.
The website goes on to discuss California’s groundbreaking efforts to reduce emissions and prepare for impacts, 
and to refute the arguments of opponents of action on climate change who have mis-characterized the science. The website has links to sections on climate science, scientific consensus, as well as climate deniers and their arguments.
