Since the days of the great early 20th century polar explorers, scientists have noticed the unbelievably bright blue ponds and streams of meltwater that can form on the glaciers and ice shelves of Antarctica and were even crucial to the recent collapse of one ice shelf.
When the health effects of climate change are discussed, the planet-scale impacts get the attention: rising temperatures, which can cause death from overheating; earlier springs, which pump more pollen toward the allergic; runoff from violent storms, which washes fecal bacteria out of sewer pipes; changing airflows that trap ozone near the ground, stressing the systems of people living with heart disease. The unpredictable weather patterns stimulated by climate change affect infectious diseases, as well as chronic ones.
There’s an unplanned experiment going on in the northern Rocky Mountains. What’s happening is that spring is arriving earlier, and it’s generally warmer and drier than usual. And that’s messing with some of the fish that live there.
Armed with a growing body of evidence that rising seas could inundate the California coastline sooner than later, state experts are sounding the alarm. A new report, “Rising Seas in California: An Update on Sea-Level Rise Science,” stresses the potential for extreme sea-level rise because of uncertainties in projections of how ice sheets will melt due to their unique, hard-to-understand physics.
Ryan Zinke should forgive Californians for any skepticism as he confers with Gov. Jerry Brown on his first visit to California as President Donald Trump’s Interior secretary. … On this visit to California, Zinke should expect that Brown will discuss the existential threat posed by climate change and the impact of sea level rise on the state’s water delivery system.
A state-commissioned report on climate change released Wednesday raises the stakes for fighting global warming, offering a clearer and, in some cases, more catastrophic picture of how much sea levels will rise in California.
California’s climate has long been dominated by cycles of intense dry conditions followed by heavy rain and snow. But never before in recorded history has the state seen such an extreme drought-to-deluge swing.
This week on Sea Change Radio, we hear from environmental writer Jeremy Miller who discusses his recent New Yorker article chronicling California’s deep, systemic water problems. Miller talks about the impact of the flooding in Northern California, shares ideas from experts on how to re-charge the state’s stressed groundwater reserves, and posits that California needs a more sustainable model for fresh water that is less dependent on the snow pack in the Sierra Mountains.
In just 15 years, flooding due to sea-level rise could inundate some 700 buildings across 5,000 acres, affecting the lives of tens of thousands of Marin residents, according to a new county report. And the draft Marin Shoreline Sea Level Rise Vulnerability Assessment, to be presented Tuesday to the Marin Board of Supervisors, says that is only the beginning.
Gov. Jerry Brown declared the end of California’s drought emergency on Friday, stressing that water conservation must be a permanent part of life as the state adapts to climate change and prepares for the next drought.
tartlingly green hills, surging rivers and the snow-wrapped Sierra Nevada had already signaled what Gov. Jerry Brown made official Friday: The long California drought is over. Brown issued an executive order that lifts the drought emergency in all but a handful of San Joaquin Valley counties where some communities are still coping with dried-up wells.
Researchers at Climate Central have put together a handy tool which lets you see just how bad summers will get by 2100, if global warming predictions are accurate and nothing is done to stop the upward trend.
But now comes the harder part for many Californians: In 2015, AB 32 will begin to cover companies that produce transportation fuels, including gasoline. That means oil companies will begin paying for the greenhouse gases their products emit, a cost the oil companies say they will pass on to consumers.
From the San Bernardino County Sun, in a commentary by Thomas Elias:
California ranchers are now among the first interest groups to realize that like it or not, global warming can no longer be denied with any semblance of accuracy. For very gradually, ranchers are seeing the grasslands they depend upon to feed their cattle begin to shrink and convert naturally to shrub land.
From the California Department of Fish and Wildlife (CDFW):
The California Department of Fish and Wildlife (CDFW) is hosting its third speaker series with a presentation on the effects of climate change on salmon and steelhead trout in the American River. The event will be held at the Nimbus Hatchery Visitor Center in Rancho Cordova on July 17 at 7 p.m.
From the Environmental Defense Fund EDF Voices: People on the Planet blog, in a post by Rebecca Shaw:
Nobody escapes climate change, especially not farmers. The report released this week by a group of prominent and politically diverse business leaders and public officials stood out, in part, because of the alarming losses it forecasts for America’s agricultural industry.
