Back in 1989, Californians received a sobering warning: The accumulation of heat-trapping gases in the atmosphere would likely bring more droughts, floods, fires and heat waves to the state.

In the 30 years since, those projections of what would happen in a warming world have proven to be remarkably prescient.”We’ve already observed some of the things we expected in 1989,” said Susan Fischer Wilhelm, a research manager at the California Energy Commission, the agency that compiled the report.
