The state's EPA released a dire report Wednesday on the local impacts of climate change.On the same day, the California Energy Commission unanimously voted to approve measures requiring solar panels on all new homes.

Average night temperatures have risen, spring runoff from the Sacramento River has decreased, more wildfires are blazing and glaciers are shrinking in the Sierra Nevadas. All these are the dire impacts of climate change happening in California, according to a new report released Wednesday by the state's Environmental Protection Agency.

To be sure, the details of the report aredisturbing, but the state is nottaking the news lying down. Instead, it is continuing to lead the fight against human-caused climate change by imposing new measures to curbharmful greenhouse emissions.

On the same day the 350-page"" report was released, the California Energy Commission unanimously voted to approve measures requiring solar panels on all new homes, condos and multi-family buildings up to three stories high beginningin 2020. The requirement is a historic first in the United States and is in keeping with the state's ambitious zero netenergy goals to reduce greenhouse emissions.

The reporttracks 36 climate indicators and compiles research from numerous studies and scientists. The authors concluded that "climate change is not just a theory" but is "a real, immediate, and growing threat to California’s future."

"The extreme weather events of the last several years are not isolated incidents," Matthew Rodriquez, secretary of the CaliforniaEPA said in the report. "They are suggestive of the significant and increasingly discernible impacts of climate change in California. The most dramatic impacts include wildfires that are larger and more frequent, and the most severe drought since recordkeeping began."

One of the more disturbing findings, the scientists note, is the increase in the average nighttime temperatures, which have increased by 2.3 degrees over the past century.

Other findings in the report include:

• An increase in extreme heatwaves and accompanying droughts since 1950

• A9 percent decrease in snowpack since 1906.

• The Sierra Nevada's largest glaciers shrunk by up to 70 percent.

• Lake Tahoe warmed by one degree since 1970 and has warmed 10 times faster over the past four years.

• The mean sea level in San Francisco has risen 7 inches since 1924.

• Oxygen depletion has also been detected in the water off San Diego.

• The five largest fire years since 1950 have all occurred since 2006.

Despite the litany of dire impacts presented in the report, the state has had some success in efforts to combat climate change by reducing harmful emissions, Rodriquez said.

"Our state’s pioneering efforts to curb emissions of greenhouse gases are working," he said. "Concentrations of the short-lived climate pollutant black carbon have dropped by more than 90 percent over the last fifty years."

Rodriquez also noted thatCalifornia is on course to meet a target of reducing greenhouse gas emissions to 1990 levels by 2020 and is well on the way to meetingthe additional reduction of emissions by a further 40 percent below 1990 levels by 2030, as laid out in the state's .

Rodriquez says the report "underscores the importance of our continued efforts to fight climate change."

"It is also intended to be a valuable resource for leaders and policymakers undertaking the critical work of climate adaptation and mitigation," he added.

The unanimous vote by theCalifornia Energy Commission to require solar panels on new homes is one way the state may be able to, said state Sen.Scott Wiener (D-San Francisco) in a statement.

"By adopting this policy we can expand solar power throughout California, which is more crucial than ever as Donald Trump and the Federal Administration try to reverse all the progress we have made to combat climate change," Wiener said. "Once again, California is showing its leadership in our fight for a 100 percent renewable energy future."
