If you want to know what climate change means for California’s water supply, consider the last two Februaries. In 126 years of statewide record-keeping, you can’t find a drier February than the one we just experienced. But February 2019 was the third-wettest on record.
Recent climate models are ‘running hot,’ projecting catastrophic global warming. Puzzled scientists are weighing whether the models need correcting or whether severe warming is a real threat.
The House Select Committee on the Climate Crisis recently released its Climate Crisis Action Plan as a comprehensive framework to address environmental issues moving forward. The plan, ‘Solving the Climate Crisis: The Congressional Action Plan for a Clean Energy Economy and a Healthy, Resilient, and Just America,’ outlines ambitious policies to combine economic growth with the development and implementation of environmental solutions.
A major water source for the Valley is considerably more drought resistant than previously thought. New research shows the water that flows into the Salt and Verde rivers is four times less sensitive to climate change than the Colorado River. The Show spoke with Bo Svoma, a scientist and meteorologist with the Salt River Project, about the significance of the new findings.
The amount and location of available terrestrial water is changing worldwide. An international research team led by ETH Zurich has now proved for the first time that human-induced climate change is responsible for the changes observed in available terrestrial water.
Across much of the United States, the flood risk is far greater than government estimates show, new calculations suggest, exposing millions of people to a hidden threat — and one that will only grow as climate change worsens.
Drought can mean restrictions for watering the lawn, crop losses for farmers and an increased risk of wildfires. But it can also hit you and your power company in the wallet.
California spent 376 weeks in a drought, from December of 2011 until March of 2019. That’s the longest duration of drought we’ve ever seen here in the Golden State. Now a study by Scripps Institution of Oceanography suggests wet and dry extremes in California are likely the result of severe storms called Atmospheric Rivers.
As a biologist and environmental advocate, even before the pandemic, I was scared by the headlines about our planet: A 75% decline in insect biomass with a 40% loss of insect species predicted; a United Nations warning of the imminent extinction of 1 million species worldwide; a 3 billion loss of birds in United States and Canada over the past half-century; the growth of dead zones on our coasts and the decline in the oxygen held by the world’s oceans. Climate change will only worsen these environmental problems.
California has been a global leader in heading off global warming, enacting laws to slash the state’s greenhouse gas emissions linked to climate change by 40% by 2030 and 80% by 2050. To do so, local governments must draft formal Climate Action Plans that document how to meet their own mandates.
