Seeing Clouds Clearly: Are They Cooling Us Down or Heating Us Up?
Though scientists know that clouds are critical to the climate system, their exact role is still uncertain. New studies are starting to fill in the knowledge gap.

The Rebirth of a Historic River
“My great uncle and my grandma and my great grandparents and, I’m sure, their great grandparents: they were all fishermen. That’s just what they did – they fished and it was out of necessity to support their families. And it’s because that’s what we’ve always done and we’ve never known another life,” says Amy Cordalis, the general counsel of the Yurok, and a member of California’s largest indigenous tribe.
It’s hard to overstate how important this livelihood has been to the Yurok people who have lived for millennia in rural Northern California. And yet this livelihood has been diminishing for decades after the Klamath River – which flows through the tribe’s territory – was dammed for hydroelectricity. But now, after years of painstaking negotiations, the fortunes of the Yurok could be set to change, with the largest dam removal project in US history given the green light.
Will the West Figure Out How to Share Water?
In Crowley County, Colorado, sugar beets and alfalfa used to line the fields. It’s cantaloupes were famous.
But that all changed about three decades ago when most of the farmers sold their water rights to rapidly growing cities on the Front Range.
Coronavirus Lockdown Caused Dramatic Changes in Water Consumption, Research Finds
New research has found that the coronavirus lockdown led to dramatic changes in water consumption in England and Wales, and that some of these are likely to continue even after the pandemic.
Fishing, Environmental Groups Sue Over Umpqua River Dam
A coalition of environmental and fishing groups are suing a water district in southern Oregon over an aging, privately owned dam that they say hinders the passage of struggling salmon populations in the pristine North Umpqua River.
The lawsuit, filed Friday in U.S. District Court in Eugene, asks a judge to order the Winchester Water Control District to build a new fish ladder and make major repairs to Winchester Dam, which dates to 1890 and is on the National Register of Historic Places. The dam is one of the oldest in Oregon.
Biden’s EPA Expected to Pass Limits on Some ‘Forever Chemicals’
The EPA under a future Biden administration is expected to quickly move to set regulations on “forever chemicals” in water and other areas, but not to restrict the entire group of thousands of the substances, attorneys said in recent interviews.
The Environmental Protection Agency is already expected to set national drinking water limits for two of these chemicals, perfluorooctane sulfonate, or PFOS, and perfluorooctanoic acid, or PFOA, said Cynthia AM Stroman, a partner in King & Spalding LLP’s Washington, D.C. office.
Wildfires Emerge as Threat to Water Quantity Across Parched West
As the largest wildfire in Colorado history spread beyond 200,000 acres, Mark Kempton began to worry it would incinerate so much of the Fort Collins watershed that the city would be unable to guarantee water to its residents.
When the spring rains come next year, ash and debris will pour down the slopes of the Rocky Mountains and clog the city’s water intake on the Cache la Poudre River, said Kempton, interim director of Fort Collins Utilities, which oversees the water supply for Colorado’s fourth-largest city.
2020 Delivers Setbacks For Some Long-Planned Western Water Projects
2020 has been a tough year for some of the Colorado River basin’s long-planned, most controversial water projects.
Proposals to divert water in New Mexico, Nevada and Utah have run up against significant legal, financial and political roadblocks this year. But while environmental groups have cheered the setbacks, it’s still unclear whether these projects have truly hit dead ends or are simply waiting in the wings.
Report: Oroville Dam Safe, but Still Vulnerable
It appears that repair work on the Oroville Dam’s damaged spillways has paid off.
A team of experts released their findings Monday, concluding that no urgent repairs are needed right now on the Oroville Dam. The report goes on to say that the largest earthen dam in America is safe to operate. However, the Oroville Dam is not completely in the clear.
State Shares Framework for New Surface Water Quality Protections
The Arizona Department of Environmental Quality is beginning to draft a set of regulations to protect surface water following the Trump administration’s rollback of the Clean Water Act.
The changes that took effect in June significantly narrow the list of waters that receive federal protection from pollution and contaminants, known as “waters of the U.S.” or the acronym “WOTUS.” And that leaves a big regulatory gap in Arizona, which currently has no surface water protection program.
