ExxonMobil is one of the world’s worst climate polluters, emitting more than 90 million metric tons of greenhouse gases in 2024. But that only accounts for its direct emissions from oil and gas drilling, refining gasoline and other fossil fuels, as well as from producing plastics.
By any measure, California’s San Joaquin Valley is one of the preeminent farming regions in the world. The agriculture industry’s seemingly bottomless thirst gives the Valley another distinction: It is losing its groundwater.

For decades, California has been on the cutting edge of US environmental policy. The state has enacted landmark measures to regulate air and water pollution, protect residents from exposure to toxic chemicals, and combat the climate crisis. Many of its groundbreaking policies have spread to other states.

Last year California shipped more than 156 million pounds of plastic waste to poor countries, with almost three-fourths sent to Mexico and another 44 million pounds sent to developing nations in Asia, Latin America, and Africa. That’s the reality behind the blue recycling bins Californians fill with plastic waste for curbside pickup. We may think we’re recycling, but we’re really sending much of our waste out of sight, out of mind.
FEMA’s denial of funds and the state’s lagging response have left toxics experts and homeowners fearful of what lies beneath the thousands of burned lots.
In the years after World War II, the smog in Los Angeles was so thick that at times people could see no farther than three blocks.
Despite efforts to limit emissions from power plants and oil refineries, the eye-burning, lung-choking blanket of smog remained. Then, in the 1950s, groundbreaking research by a biochemistry professor at the California Institute of Technology, Dr. Arie Haagen-Smit, determined that the main culprit was automobile exhaust.
The most powerful man in the world is waging war on a tiny, almost extinct fish. The fish is the minnow-like delta smelt, less than three inches long with a lifespan of only a year. Its sole natural habitat is the Sacramento-San Joaquin River Delta.

A driver entering an enclosed parking garage in California is greeted by a 20-by-20-inch sign declaring in 72-point type:

The horrific fires that incinerated more than 40,000 acres in Southern California last month were still burning when newly-inaugurated President Trump flew in to view the devastation. At a Jan. 24 press briefing with local officials, he groused that he had heard people who lost their homes would not be allowed to rebuild for up to 18 months.
Of California’s dozens of landmark laws to curb climate-heating greenhouse gases and health-threatening air pollution, none is more ambitious than the rule that by 2035 all new passenger cars and trucks sold must be zero-emission vehicles (ZEVs) that run on electricity.
