“An international panel of scientists has found with near certainty that human activity is the cause of most of the temperature increases of recent decades, and warns that sea levels could conceivably rise by more than three feet by the end of the century if emissions continue at a runaway pace.”
“Marin’s majestic redwoods — and others around the state — are experiencing unprecedented growth due to warmer temperatures and sunnier skies brought on by climate change, according to a report released Wednesday by the Save the Redwoods League.”
“California is feeling the effects of climate change far and wide, as heat-trapping greenhouse gases reduce spring runoff from the Sierra Nevada, make the waters of Monterey Bay more acidic and shorten winter chill periods required to grow fruit and nuts in the Central Valley, a new report says.
“Though past studies have offered grim projections of a warming planet, the report released Thursday by the California Office of Environmental Health Hazard Assessment took an inventory of three dozen shifts that are already happening.”
It could take a few hundred years – or even 2,000 – but the eventual, permanent flooding of low-lying areas in Sacramento is guaranteed if greenhouse gases are not deeply reduced, according to new research. …
“A new study shows that the largest U.S. cities highly threatened by future sea level rise are Miami, Virginia Beach, Va., Jacksonville, Fla., and Sacramento.”
“As some Americans, including some in Congress, continue questioning whether climate change exists, a group of world-class scientists has documented its very real effects even now in California. A report released Thursday by the state Environmental Protection Agency makes clear the alarming threats posed by global warming.”
“California lakes are warming, sea levels are rising, wildfires are spreading, and mountain plants and animals are migrating to higher ground as the impact of climate change takes hold throughout the state, a new report says.
“The evidence of the effects of the warming trend emerged in an analysis of 36 ‘indicators’ – warning signs of changes – that are detailed in the 240-page report released Wednesday by the state’s Environmental Protection Agency.”
“The folks at Climate Central made another splash last week, releasing lists of cities that they argue could end up at least 50 percent underwater if carbon reductions are not achieved by certain ‘locked-in’ dates.
“Yes, Stockton’s on the list. In fact, it has the earliest ‘locked-in’ date in the entire state – the year 2051.
From the U.S. Environmental Protection Agency (EPA) “It’s Our Environment” blog:
“EPA Administrator Gina McCarthy will host her first live Twitter chat on climate change on Friday, August 2, at 12:30 PM ET. Administrator McCarthy will discuss her plans for the agency moving forward, focusing on EPA’s work to combat climate change.
“Helping communities adapt to the changing climate and cutting carbon pollution will be a significant part of EPA’s work over the coming years – the Agency will play a key role in implementing President Obama’s Climate Change Action Plan.
“In a forum convened Tuesday by the Bicameral Task Force on Climate Change, a panel of experts on climate, wildfires, and forestry met with task force cochairs Rep. Henry Waxman, D-Calif., Sen. Sheldon Whitehouse, D-R.I., and other lawmakers to discuss the impact of climate change on wildfires.”
“The idea that glaciers change at a glacial speed is increasingly false. They are melting and retreating rapidly all over the world. But the unpredictable flood surges at the Mendenhall Glacier, about 14 miles from downtown Juneau, Alaska’s capital, are turning a jog into a sprint as global temperatures and climate variability increase.”
“Lawmakers are taking a more detailed look at the implications [of climate change] during a Select Committee On Sea Level Rise And The California Economy hearing assessing how rising water will affect the agriculture, tourism and fishing industries in a state renowned for its coastlines.”
“Fish populations off the Southern California coast have dropped by 78 percent over the past 40 years, a new study shows, and an author of the study says the sharp declines are most likely caused by global warming.”
“Tackling one of the American West’s most contentious issues, a new government report assesses the demands on Sonoma County’s largest underground water source against a future that includes population growth, agricultural needs and the wild card of climate change.
“Stanford environmental scientist Katie Arkema and her colleagues published a national map on Monday, showing where coastal reefs and wetlands are keeping communities safe, and which areas may need more preservation.”
“Power plants across the country are at increased risk of temporary shutdown and reduced power generation as temperatures and sea levels continue to rise and water becomes less available, the Energy Department said Thursday.
“A paper published Wednesday suggests that trees in at least some parts of the world are having to pull less water out of the ground to achieve a given amount of growth. Some scientists say they believe that this may be a direct response to the rising level of carbon dioxide in the air from human emissions, though that has not yet been proved. …
