Climate change involves natural and man-made changes to weather patterns that occur over millions of years or over decades.
In the past 150 years, human industrial activity has accelerated the rate of change in the climate due to the increase in greenhouse gases (carbon dioxide, methane, and nitrous oxide). Scientific studies describing this climate change continue to be produced and its expected impacts continue to be assessed.
In California, the California Environmental Protection Agency has found temperatures have risen by about 1.5 degrees since 1895. Looking ahead, temperatures could rise by 2.7 degrees and its sea levels by 55 inches in the next 40 years, according to the California Energy Commission and the California Natural Resources Agency. These are among the ongoing issues the state faces as it grapples with climate change.
Already, California is confronting rising demand for water and diminishing supplies. At the same time, the state’s water infrastructure such as levees is increasingly aging and in disrepair—conditions expected to be made worse by climate change.
When the health effects of climate change are discussed, the planet-scale impacts get the attention: rising temperatures, which can cause death from overheating; earlier springs, which pump more pollen toward the allergic; runoff from violent storms, which washes fecal bacteria out of sewer pipes; changing airflows that trap ozone near the ground, stressing the systems of people living with heart disease. The unpredictable weather patterns stimulated by climate change affect infectious diseases, as well as chronic ones.
A state-commissioned report on climate change released Wednesday raises the stakes for fighting global warming, offering a clearer and, in some cases, more catastrophic picture of how much sea levels will rise in California.
California’s climate has long been dominated by cycles of intense dry conditions followed by heavy rain and snow. But never before in recorded history has the state seen such an extreme drought-to-deluge swing.
Gov. Jerry Brown declared the end of California’s drought emergency on Friday, stressing that water conservation must be a permanent part of life as the state adapts to climate change and prepares for the next drought.
tartlingly green hills, surging rivers and the snow-wrapped Sierra Nevada had already signaled what Gov. Jerry Brown made official Friday: The long California drought is over. Brown issued an executive order that lifts the drought emergency in all but a handful of San Joaquin Valley counties where some communities are still coping with dried-up wells.
California’s water regulators are looking to strengthen their focus on climate change, adopting policies aimed at helping the state prepare for more severe floods, more extreme droughts and shrinking snowpack.
To friends and critics, Mr. [Scott] Pruitt seems intent on building an E.P.A. leadership that is fundamentally at odds with the career officials, scientists and employees who carry out the agency’s missions. That might be a recipe for strife and gridlock at the federal agency tasked to keep safe the nation’s clean air and water while safeguarding the planet’s future.
The drought has been declared over in most of California, with heavy winter rains sending water over the Oroville dam and forcing the evacuation of nearly 200,000 people. But climate change is still in the air, and the recent weather pattern is a harbinger of what’s to come.
Above-average snowpack in the Rocky Mountains this year may bring some relief to the Colorado River Basin, which has been in a drought since 2000. But the long-term picture for the region is less rosy after a newly published study found just how much higher temperatures are impacting river flow.
Jeffrey Mount, a leading expert on California water policy, remembers the last time a crisis at the Oroville Dam seemed likely to prompt reform. It was 1997 and the lake risked overflowing, while levees further downstream failed and several people died.

A speeding wildfire in California that turned hundreds of homes near Lake Isabella to piles of twisted rubble has forced a conversation about how to minimize destruction in the most populous state experiencing the effects of climate change.
California has been diligently trying to reduce use of fossil fuels and cut greenhouse gas emissions. Last year, Gov. Jerry Brown signed Senate Bill 350, which requires 50 percent of the electricity from utilities to come from renewable sources by 2030. But it’s not just energy utilities that can add more renewables to their portfolios – water suppliers can, as well, although they aren’t mandated to do so.
To understand what the future holds, sometimes we have to look at the past, Bruce Daniels has learned. Daniels is trying to help Californians understand future water availability by examining 85 years of daily precipitation records.
