A Mexican activist described the most recent drought as “deadly” and climate change as a “silent killer.”

“California is under siege from climate change," Humberto Campa Flores, president of the Coalition for Clean and Fair Energy, told the San Gabriel Valley Tribune on Monday at a Rancho Cucamonga forum on climate change.

He highlighted that although it’s been for years that researchers have confirmed the impacts of climate change, a major drought in 2007-2009 were “even worse” than many believe.

“The last five years, California’s had a dry year every single year,” Campa Flores said.

He said that while local farmer have reported a 40% reduction in water sales since 2015, a lack of some forms of federal aid is working to keep the state reeling.

Campa Flores also said the state was being left vulnerable by the U.S. Environmental Protection Agency.

In a state where thousands of potential indigenous farmers have to operate off helicopters, helicopters won’t fly over the land they were scraping last year.

The Desert Conservation League, an environmental organization based in San Bernardino County, has been collaborating with the agnostic Southern California Coastal Water District to try to get more federal funding for access to water.

“At some point, we’re going to have to start adapting to the laws of science and adapt to reality,” Sean Rushton, the organization’s president, said.

As the drought lingers, cities like Los Angeles have been seeing more rain as in any winter this time of year and water is flowing into local reservoirs.
