To scientists who study lakes and rivers, it seems humans have embarked on a huge unplanned experiment. By burning fossil fuels, we have already raised the concentration of carbon dioxide in the atmosphere by 40 percent, and we’re on track to increase it by much more. Some of that gas may mix into the world’s inland waters, and recent studies hint that this may have profound effects on the species that live in them.
To address future climate change effects on water resources, scientists at five UC campuses, and Lawrence Livermore and Lawrence Berkeley National Laboratories will study California’s water systems, from the headwaters in the Sierra Nevada, through rivers, reservoirs and groundwater in the Central Valley. The goal is to provide information to optimize water storage, quality and groundwater sustainability.
In December, the city and county of Santa Cruz joined a wave of coastal California communities suing fossil-fuel companies for climate-change related damages. On Monday, ExxonMobil pushed back against what it called “abusive law enforcement tactics and litigation,” threatening to file its own legal action and accusing the local jurisdictions of hypocritically omitting reference to climate change damages from their own bond disclosures.
California must step up to blunt Trump’s destructive agenda on water as we have on climate change. And we have the framework in place to do so. Our State Water Resources Control Board and nine regional water boards are our bulwarks against the degradation of our coast, surface water and groundwater.
The U.S. Environmental Protection Agency will replace Obama-era carbon and clean water regulations and open up a national debate on climate change in 2018, part of a list of priorities for the year that also includes fighting lead contamination in public drinking water.
When the trees are bare, climate scientist and meteorologist David Gutzler has an unobscured view of the Sandia Mountains from his office window. … Gutzler, 62, has spent the last two decades teaching climatology and meteorology at UNM [The University of New Mexico] but said he never expected that his field of study, which has focused on monsoonal patterns, drought and the impacts of climate change on state water resources, would be the subject of so much controversy.
New York will be the first major metropolis to be remapped taking into account the realities of climate change, like rising sea levels and increasingly powerful storms. … As a result, FEMA and city officials say, New York could be an example for other places around the country.
The Interior Department is dialing back more environmental goals set in the Obama administration, this time through a secretarial order. In a three-page order issued without fanfare Dec. 22, Deputy Interior Secretary David Bernhardt rescinded three Obama-era documents involving environmental mitigation and one involving climate change policy.
For trout in the rivers above Oroville Dam, survival is a slough. They have been navigating around dams in waters sullied by a century of logging, ranching and road building. Now they face streams shared with invasive species hitchhiking around the world at a pace accelerated by climate change. How’s a fish to endure?
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.
Climate change is likely to exact enormous costs on U.S. regional economies in the form of lost property, reduced industrial output and more deaths, according to a report backed by a trio of men with vast business experience.
