Why it’s important to save our seas’ pristine places

Yet the ocean is still home to treasure troves of biodiversity, and evidence is mounting that protecting such significant local areas builds resilience to climate change—and can even help regenerate what has been lost.

“We’ve done a lot for this global environment, but we’ve done very little for the needs of these communities,” said Garcia, a Mexican-American who heads the Assembly Natural Resources Committee.

The effects of climate change will force millions to migrate. Here’s what this means for human security

In 2015, the U.N. Refugee Agency counted 65.3 million people around the world as “forcibly displaced,” including about 40 million within their home countries. Wars, ethnic conflicts, economic stresses, famines and disasters are among the reasons people leave their homes.

Climate change clues revealed by ice sheet collapse

The rapid decline of ancient ice sheets could help scientists predict the impact of modern-day climate and sea-level change, according to research by the universities of Stirling in Scotland and Tromsø in Norway.

California’s landmark climate-change program would also fight air pollution under proposal

Air pollution — not just climate-warming greenhouse gases — would be melded into the complex cap-and-trade program under Assembly Bill 378, by Assemblywoman Cristina Garcia. Garcia heads the Assembly’s Committee on Natural Resources, which passed the proposal.

What a year with a single tree reveals about climate change

Recorded year after year, studies brought home a global reality: The seasons are not what they used to be. On average, spring is earlier. Fall is later. And winter is getting squeezed on both ends.

Climate change is making algal blooms worse

A new study has unpicked how warming ocean temperatures have already driven an intensification of blooms around North America — the first time this link has been established at an ocean scale.

Storm damage to top $14 million for Bay Area parks — and we’re not done yet

Bay Area parks and open spaces suffered more than $14 million damage from winter storms, and the toll is expected to rise much higher as record-setting rain lingers into spring.

As climate warms, the oceans are becoming more toxic, new research shows

Researchers at Stony Brook University, in New York, analyzed the effects of rising ocean temperatures on two of the most toxic types of algae and found growths are becoming more widespread and profiling through the North Atlantic and North Pacific oceans.

Great Barrier Reef 'cooking and dying' as seas heat up, warn scientists

More than two-thirds of the coral in Australia's Great Barrier Reef is experiencing "shocking" amounts of bleaching, new aerial surveys have revealed. The Australian government says climate change is mainly to blame.

The trees that make Southern California shady and green are dying fast

One type of beetle could kill as many as 27 million trees in Los Angeles, Orange, Riverside and San Bernardino counties, including parts of the desert. Trees that shade, cool and feed people from Ventura County to the Mexican border are dying so fast that within a few years it’s possible the region will look, feel, sound and smell much less pleasant than it does now.

Can we fight climate change with trees and grass?

Earth's greenery comes with natural carbon-capturing abilities, but now several studies are investigating how to tweak those tendencies to have a maximum impact on carbon dioxide levels in the atmosphere.

Researchers show connection between extreme weather and climate change

Stanford researchers have found that global warming from human emissions has made extreme hot weather events more likely across over 80 percent of the areas of the globe for which observations are possible.

In the battle over California climate policies, green projects are now in the hot seat

Lawmakers are debating how to continue the state’s fight against climate change; the system is being targeted by some environmentalists who would rather force industry to directly reduce its emissions.

6 climate tipping points: How worried should we be?

Environmentalists anticipate six "tipping events" that may occur in the future due to the acceleration of climate change.

How Americans think about climate change, in six maps

New data released by the Yale Program on Climate Communication provides a deeper look at public opinion on global warming.

Climate change is making us sick, top U.S. doctors say

A report by top American doctors predicts that climate change will ultimately lead to the deterioration of human health in various aspects.

Study: 'Urgent' action against global warming needed to save coral reefs

The researchers documented the extent of the damage the reef off the coast of Australia, and found that only 8.9 percent of more than 1,000 reefs escaped with no bleaching along a stretch more than 2,300 kilometers long.

The U.S. Geological Survey hails an early spring — and ties it to climate change

The arrival of an early spring in the United States is a major indicator of the sweeping changes caused by climate change. Researchers have identified the risks and disadvantages of this current phenomenon.

California’s oil is an opportunity to combat climate change

As the country's third-largest oil producing state, California must reduce its oil refinery emissions by 20 percent by 2030.

California won't meet its climate change goals without a lot more housing density in its cities

If California is going to meet its sustainability goal by 2030, then the state must first solve its housing density problem.

Climate change adds stress to California dams

Older dams may not be designed to deal with the severe weather patterns California has experienced because of global warming.

Sea levels may rise by more than 8 feet by the year 2100 due to climate change

A new report shows that under extreme future climate change, global sea levels could rise by more than eight feet by the end of the century — one of the highest estimates yet to be presented in a federal report.

Why we should be worried about California’s coast

California State Treasurer John Chiang speaks on the need to protect the environment from offshore drilling especially in California.
