As climate change drives temperatures higher, scientists are finding places that are warming slightly less. They're known as "climate refugia."

The move fulfills a Trump campaign promise to help California's farmers. But it ignores the warnings of federal biologists who were sidelined.

Residents are wondering whether widespread power outages are the future and whether they're the only way to prevent wildfires. New technology may help prevent them if utilities are willing to invest.

When it comes to surviving the warming climate, scientists are finding that some plants and animals have an edge. The hope is that these "super adapters" can help preserve their species.

As more cities and states try to cut carbon emissions, natural gas is becoming a target. The city of Berkeley, Calif., just became the first to ban it in new homes, but it may not be the last.

To help meet its ambitious climate goals, California is paying farmers to grow cover crops. The aim is to promote healthier soil that can absorb more carbon from the atmosphere.

Cover crops can make soil healthy and help it soak up a lot of carbon. Now, California is paying farmers to grow them, to help meet its ambitious climate goals.

The Trump administration wants to allocate more of California's water to farmers. Internal government emails show concern that the change is being pushed too fast for adequate scientific review.

PG&E is key to helping California meet its ambitious goal of zero carbon electricity by mid-century. Now there's concern that the utility's bankruptcy may set that back.

There is concern that California's climate goals could suffer a set back because of PG&E's bankruptcy filing. The utility is key to helping the state's grid become 100 percent carbon free.

Gov. Jerry Brown has helped make California a global leader in addressing climate change. As he leaves office, we look back on what he achieved and what he could not.

New technology builds on existing models and adds in the growing amount of real-time data available from NASA satellites, weather stations, field cameras and aerial reconnaissance flights.

In northern California, homes are being rebuilt in the same area that burned to the ground in last year's Tubbs Fire. Despite the risk, a severe housing shortage in the area is forcing tough choices.

Governors and mayors from around the world are making new pledges to cut carbon emissions. They're in San Francisco this week, trying to counter the Trump administration's rollbacks on climate change.

Gov. Jerry Brown of California wants the state to radically cut carbon emissions. But to meet those goals, every new vehicle sold in California by 2040 will have to be a zero-emission model.

A new California law mandates that the state move to 100 percent clean energy for electricity in the state by 2045. But getting rid of fossil fuel power will be a challenge.

The Trump administration announced plans Thursday to freeze fuel-efficiency standards on cars and trucks by 2020. They argue the move will keep car prices lower and improve safety.

California is putting almost $3 billion toward new water storage projects to help preserve its crops during droughts. Some say that money should go to dams and reservoirs, but others want a less environmentally problematic approach.

In the 1980s, California towns used local zoning rules to block offshore oil and gas drilling. State lawmakers are considering a similar strategy to push back against the Trump administration.
