Climate change

New York Times

For over 150 years, California has collectively embraced an identity as a place where people go to reinvent themselves and to remake the world. From the Gold Rush to the Silver Screen; from valleys of wheat and oranges to valleys of microprocessors and software – the Golden State’s story is one of innovation and riches, but also tension over what has been lost in the process of creating the future. 

Study Shows Wildfires Occurring At Higher Elevations

A new study shows wildfires are increasingly occurring at higher elevations in the Sierra Nevada. As Amy Quinton reports from Sacramento, researchers say climate change and some forest management practices may be driving the change.

Scientists say in the early 20th century, fires rarely burned above 8,000 feet in the Sierra. But in the past three decades, several fires have burned at or above that level every year. The study suggests warming temperatures associated with climate change may be increasing tree density and the amount of fuel.

This week on Valley Edition Mark Keppler, the executive director of the Maddy Institute, talks about the state of trails in the region. Also on the program Daniel Swain, with Stanford's Woods Institute for the Environment, talks about a new study examining the link between drought and global warming released last week.

California is now in the fourth year of its on-going drought, and this winter’s meager snowpack has water experts worried, thanks to remarkably warm temperatures. But scientists at Stanford’s Woods Institute for the Environment say that in just a few decades, this severe condition could be the new norm, thanks to climate change.

Study Says California Drought Caused By Natural Climate Patterns

A new study by the National Oceanic and Atmospheric Administration says natural occurring climate patterns –not climate change- are the primary drivers of California’s drought. 

The NOAA study says a high-pressure atmospheric ridge off the West Coast blocked important winter storms from California for three winters. Ocean surface temperature patterns made the ridge much more likely. The decreased precipitation is almost the opposite of what climate change models project.

NASA Spacecraft Will Help California Address Drought and Floods

Scientists may soon have a more accurate way to predict the extent and severity of droughts, floods and even the amount of food California can produce. As Amy Quinton reports from Sacramento, a NASA spacecraft getting set to launch will measure soil moisture, one of the most important components of the earth’s water cycle.

Climate Change Means Less Sierra Nevada Runoff

A new study from UC Irvine shows climate change could reduce California’s water supply by changing mountain vegetation. As Amy Quinton reports from Sacramento, even researchers were surprised how much could be lost.

Governor Jerry Brown recently said, “humanity is on a collision course with nature.”  He was referring to climate change and the early advent of the fire season here in California.  In related remarks, Brown said we have to “live with nature.”

I studied to become a civil engineer with the goal of building grand things, like the Golden Gate Bridge, the Hoover Dam, and Interstate freeways. Thanks to two inspiring professors, late in my college years I began to think about the unanticipated consequences of these major engineering projects, from the displacement of homes and businesses to pollution and traffic.

Governor Jerry Brown Says California Wildfires Linked To Climate Change

California Governor Jerry Brown says human-caused climate change is probably the main reason wildfires are scorching large parts of San Diego County at this time of year.

Brown told CNN that climate change is the reason why the California fire season is now 70 days longer than it was in the past. He says high winds and dry conditions make fires larger and more devastating.

Brown:  “Those conditions are definitely caused by climate change, global warming induced by human activity.”
