Scientists Say They Can Predict Colorado River’s Annual Water Supply. What Does That Mean for Agriculture, Wildfires?

/in , , /by /Deseret News (Utah)

Scientists can now predict drought and overall water supply on the Colorado River years in advance, according to a new study published by researchers at Utah State University.

The team of scientists believe long-term “ocean memory,” in conjunction with atmospheric effects and the influence of land systems, correlates with cycles of drought in parts of the western U.S., which then leads to water shortages on the Colorado River.

With Dry La Niña Conditions, Persistent Western Drought Looms Large in Winter Outlook

/in , , /by /Los Angeles Timesby Paul Duginski

The forecast looks warm and continued dry this winter in California and the Southwest, which raises the disturbing prospect of a perpetual fire season. More than 45% of the continental U.S. is experiencing drought right now, especially in the West.

The recent wildfires and a coming dry winter from the developing La Niña amplify the perils of climate change for our fair city. These threats do not stop at the shore — holding back the ocean should also be on our radar.

Distant Seas Might Predict Colorado River Droughts

/in , , /by /Science Magby Warren Cornwall

In 2011, heavy snows in the Rocky Mountains filled the Colorado River, lifting reservoirs—and spirits—in the drought-stricken U.S. Southwest. The following year, however, water levels dropped to nearly their lowest in a century, imperiling a supply vital to millions of people and dozens of ecosystems.

Conservationists in Colorado are dreaming big. In a time of political turmoil and legislative impotence, a consortium of Colorado conservation groups is floating an audacious plan to conserve 30% of the land in the state — roughly 20 million acres — by 2030. Since statehood, the state has protected only 6 million acres.

Although these days no one seems to agree on anything, there is one thing we can all agree on: every Californian should have a right to clean drinking water. But even with that, California is facing an impending water shortage.

FEMA Ends Policy Favoring Flood Walls Over Green Protections

/in , , /by /E&E Newsby Thomas Frank

The Federal Emergency Management Agency has taken a dramatic step to encourage communities to use environmentally friendly features such as wetlands for flood protection instead of building sea walls and levees. A new FEMA flood policy released late last month with no public announcement is drawing praise from environmentalists because it will promote mitigation projects that provide environmental benefits in addition to flood protection.

Opinion: Building Long-Term Resilience to Climate Change in California

/in , , /by /CalMattersby Matthew Armsby and Marisa Buchanan

In the past decade, California has experienced its most severe drought in over a millennium, devastating floods, the hottest summer on record and eight of the 10 largest wildfires ever recorded in the state.

Within the past month, Death Valley set a new record for the hottest temperature ever recorded on earth, and wildfires burned an area larger than the state of Connecticut. Three of the largest wildfires in California history are still smoldering, the smoke from which is now visible as far away as New York City.

Climate-driven disasters are increasingly putting Californians at risk and our most vulnerable populations, comprised largely of people of color, are suffering disproportionate impacts. These populations often have the least access to parks, greenspace and health care resources, and are at increased risk from rising temperatures, poor air quality driven by wildfires and other climate change impacts.

Scripps Collaboration to Optimize Water Management & Supply

/in , , /by /The Coast News Group

The San Diego County Water Authority is partnering with the renowned Scripps Institution of Oceanography at UC San Diego to better predict atmospheric rivers and optimize water management before, during and after California’s ever-changing seasonal storms.

Atmospheric river storms produce 40%-60% of the West Coast’s annual precipitation and are responsible for the majority of flood damage in the region. Predicting and managing this is challenging due to unpredictable and changing snowmelt and rainfall.

To study this, Scripps’ Center for Western Weather and Water Extremes (CW3E) introduced the Water Affiliates Group, which brings together relevant science and water industry expertise to enhance reservoir operations along with California’s changing climate.

The Imperial County Air Pollution Control District issued Notices of Violation to California Department of Water Resources, California Natural Resources Agency, and United States Fish and Wildlife Service for failure to implement adequate dust control on the Salton Sea playa on the Species Conservation Habitat project site near Westmorland, California.

In addition, as landowners of the project site, the Imperial Irrigation District and United States Bureau of Land Management were also issued NOVs, according to a press release.
