Topic: Climate Change


Climate Change

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.

Federal judge issues ruling in ‘climate kids’ case

The federal judge who in 2016 cleared a constitutional climate case for trial in Eugene has reiterated her position that the youth-led matter should be decided in court. U.S. District Judge Ann Aiken on Monday issued a long-awaited decision that keeps intact the central claims of a lawsuit that asserts the federal government’s policies regarding the use of fossil fuels are contributing to global warming and violating the rights of 21 youth plaintiffs who first sued the government in 2015.

Why climate change is especially dangerous for low-income Coachella Valley residents

Higher temperatures, more intense droughts and more damaging wildfires and floods are just some of the climate change effects already being seen in the California desert — and residents of low-income, minority communities in the Coachella Valley are most likely to suffer the consequences of those environmental stresses. That was one of the takeaways from a series of presentations by scientific experts last week at UC Riverside’s Palm Desert campus.

Trump may not know what’s behind warming, but scientists do

Despite what President Donald Trump says, scientists have long known that what’s warming the planet isn’t natural. It’s us. They even have the energy balance sheets accounting for changes in the climate to prove it. President Trump’s own White House put out a science report last year concluding that “the likely range of the human contribution to the global mean temperature increase over the period 1951-2010 is 1.1 to 1.4 F (0.6 to 0.8 C).”

Over the past decade, California farmers have been seeing symptoms of climate change in their fields and orchards: less winter chill, crops blooming earlier, more heat waves and years of drought when the state baked in record temperatures. Scientists say California agriculture will face much bigger and more severe impacts due to climate change in the coming decades.

‘Ridiculously Resilient Ridge,’ Climate Change and the Future of California’s Water
WESTERN WATER Q&A: Climate scientist Daniel Swain

Daniel SwainEvery day, people flock to Daniel Swain’s social media platforms to find out the latest news and insight about California’s notoriously unpredictable weather. Swain, a climate scientist at the Institute of the Environment and Sustainability at UCLA, famously coined the term “Ridiculously Resilient Ridge” in December 2013 to describe the large, formidable high-pressure mass that was parked over the West Coast during winter and diverted storms away from California, intensifying the drought.

Swain’s research focuses on atmospheric processes that cause droughts and floods, along with the changing character of extreme weather events in a warming world. A lifelong Californian and alumnus of University of California, Davis, and Stanford University, Swain is best known for the widely read Weather West blog, which provides unique perspectives on weather and climate in California and the western United States. In a recent interview with Western Water, he talked about the Ridiculously Resilient Ridge, its potential long-term impact on California weather, and what may lie ahead for the state’s water supply.
