global warming

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.

California's air regulators are increasingly turning their attention to a greenhouse gas that has largely gone overlooked - methane. 

According to the U.S. EPA, when it comes to climate change, methane emissions have an impact 20 times greater than CO2 emissions, pound for pound.

That's why Governor Jerry Brown singled out the gas during his inaugural address this month as part of his plan to combat climate change.

The LA Times recently called Mary Nichols a “rock star.” In 2013 Time Magazine called her one of the 100 most influential people in the world and the Thomas Edison on environmentalism. She’s the chair of the California Air Resources Board, and if it has something to do with air quality or climate change in the state, she probably has something to say about it.

Commentary: Do We Have More Morality Than An Asteroid?

For many, climate change is still and unsettled issue.  Yet it is indisputable that throughout its long history, our planet Earth has undergone major species-destroying transformations.  We know this through a reading of the paleontological record that documents dramatic transformations over billions of years.  In this edition of The Moral Is, Professor Madhusudan Katti of Fresno State’s Biology Department explores whether, as a result of industrialization, we are yet again at another planet-altering brink.


New Poll: Support For Global Warming Laws Drop If Energy Prices Rise

A new Public Policy Institute of California poll finds a strong majority of Californians support the state’s laws to combat global warming. But as Amy Quinton reports from Sacramento, that support drops amid concerns about rising gas and electricity prices.

California Bill Would Delay Cap And Trade Transportation Fuel Permits

A California Assemblyman has introduced a bill that would delay part of the state’s greenhouse gas reduction program for at least three years. Under the bill, energy companies would be able to put off purchasing “transportation fuel pollution” permits. Capital Public Radio’s Max Pringle reports.

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.”

Rising global temperatures aren’t just an international concern, they’re also an important local issue, especially when it comes to public health. How will climate change affect everything from rates of asthma and valley fever to wildfires and natural disasters?

More wildfires.  Warmer lakes.  And higher temperatures.  A new study from the California Environmental Protection Agency cites those and other signs that climate change is having a growing impact across the state.  Ben Adler has more from Sacramento.

CalEPA has been tracking environmental indicators since the year 2000 in hopes of measuring the effects of climate change.  Here are some of the findings in the new study, based on 36 different indicators:

-       California’s high, low and average temperatures are going up – especially at night.

Californians are now more likely to urge swift state action to slow global warming than they were during the recession.  Ben Adler has more from Sacramento on that and other findings from the Public Policy Institute of California’s new poll on environmental issues.

Commentary: Are We Fiddling While the Planet Warms?

Jul 9, 2013

Can we solve the climate crisis?  Are we wise enough?  In this segment of Valley Public Radio's commentary series The Moral Is, Fresno State philosophy professor Dr. Andrew Fiala asks whether, like Nero, we are fiddling while Rome burns.


President Obama recently announced a new initiative on climate change.  But will we be able to address climate change in time to prevent the worst that is predicted?  I doubt it.  Decades of dithering about global warming do not inspire hope.

Agriculture in the Sacramento-San Joaquin Delta has flourished thanks to rich organic soils. But after more than a hundred years of farming, those soils are eroding, and the interiors of many Delta islands are sinking. California may have a solution that would not only help farmers, but could combat climate change. Amy Quinton reports from Sacramento.

California’s low carbon fuel standard may be driving the development of alternative fuels more quickly than expected. As Amy Quinton reports from Sacramento, a new report shows significant progress in fuels that can replace or blend with gasoline and diesel.

The report is produced by a coalition of utilities and alternative fuel makers. It looks at different ways companies can comply with the regulation that requires a 10 percent reduction in the carbon intensity of transportation fuels by 2020.

Environmental groups have begun a lobbying campaign to stop California Governor Jerry Brown’s budget proposal to divert money from the cap-and-trade program.

Environmentalists say money from the sale of carbon pollution permits is supposed to go to programs that help further reduce emissions. Brown wants to borrow $500 million for the general fund.

Vien Truong with the Greenlining Institute says environmental advocates are angry. She says that money could be used for clean air programs in low-income communities.

California Launches 'Pay-to-Pollute' Carbon Market

Nov 13, 2012
Joe Moore / Valley Public Radio

California is launching a big part of its fight against climate change on Wednesday. The state is holding its first auction in the "cap and trade" program where industrial businesses will have to buy allowances to emit greenhouse gases.   The goal is to reduce the state's emissions to 1990 levels by 2020. From Sacramento, Kathleen Masterson reports on how the complex market is designed to reduce pollution. 

Changing climate may expand valley fever’s impact

Valley fever feeds on heat.

And as the average temperature ticks up with each passing decade, experts are concerned that the fungus’ footprint and impact are expanding, as evidenced by a rise in cases in areas far outside the hot spots of the Central Valley of California.

In the soil, the cocci fungus lives on dead organic matter. Less rainfall and higher temperatures reduce overall vegetation, diminishing soil competition for the hardy fungus, scientists say. Cocci spores survive—even thrive—when the environment is drier and hotter since other competitors die off.

California Tests Cap and Trade System

Aug 31, 2012

California officials are ramping up for the greenhouse gas emissions cap-and-trade market this November, where companies will be required to pay for their pollution. The state held a trial auction to test the new system for selling carbon credits on Thursday.

The main goal of the test run is to make sure the software works smoothly and prevents attempts to game the bidding system, according to, Stanley Young who is with the California Air Resources Board.

This week on Valley Edition we talk about the controversy over the labeling of genetically modified foods, which will be on the November ballot as Proposition 37. We hear arguments on both sides of the issue. We also talk about the current heat wave and what is has to do with global warming, and learn more about a series of events from the Fresno County Library connected to the book Farewell to Manzanar.
