S.F. Embraces Aggressive New Climate Change Goals as Drought, Heat and Wildfires Engulf California

/in , , /by /San Francisco Chronicleby Mallory Moench

San Francisco set new, more ambitious climate change goals Tuesday, including getting to net zero greenhouse gas emissions produced in the city by 2040, as wildfires, drought and heat waves worsened by climate change plague California and floods in Europe grab headlines.

The Board of Supervisors unanimously approved an update to the environment code that pledges the city will cut its greenhouse gas emissions to at least 61% below 1990 levels by 2030. The city wants to reduce emissions generated outside city borders for products consumed in San Francisco – such as the carbon footprint of SFO air travel – by 40% by 2030 and 80% by 2050.

Opinion: Californians Will Adapt to Living With Drought, As We Always Have

/in , , /by /CalMattersby Jay Lund

Climate change is exacerbating droughts and accelerating the transformation and decline of California’s native forest and aquatic ecosystems.  As a state, we are poorly organized to manage these effects, which need extensive focused preparation.  We need to adapt (and we will make mistakes in doing so).  Our human, economic and environmental losses will be much greater, however, if we manage poorly because of delay, complacency or panic.

Opinion: California Drought Sharpens Perpetual Water Conflict

/in , , /by /CalMattersby Dan Walters

California never has enough water to meet all demands and even when supplies are relatively robust there’s a triangular competition over their allocation. Farmers, municipal users and environmental advocates vie for shares of water that has been captured by California’s extensive network of dams and reservoirs. Their battles are waged in the state Capitol, in Washington, in regulatory agencies and in the courts and over time, the trend has been a subtle shift of supplies from long-dominant agriculture to protecting flows for fish and other wildlife while maintaining the relatively small amount consumed in urban areas.

Final Plan for Water Releases Into Sacramento River Could Kill Up to 88% of Endangered Salmon Run

/in , , /by /San Francisco Chronicleby Tara Duggan

The California water board has approved a plan for water releases into the Sacramento River that could kill off an entire run of endangered chinook salmon and put at risk another population that is part of the commercial salmon fishery.

The State Water Resources Control Board has informed the federal Bureau of Reclamation it would accept its final plan for managing water flows from Shasta Lake into the Sacramento River, which is both the main source of water for Central Valley farms and the spawning habitat for chinook salmon. Because the bureau’s plan involves releasing water to irrigation districts earlier in the season, the river will be lower and warmer during salmon spawning season and could result in killing as many as 88% of endangered winter-run chinook eggs and young fish.

California’s Biggest Heat Wave of the Year Heightens Drought and Fire Fears

/in , , /by /Los Angeles Timesby Hayley Smith and Lilia Seidman

With a worsening drought gripping the West and wildfire season looming, California is bracing for the most severe heat wave of the year — one that promises to tax the state’s power supplies while also offering a grim preview of challenging months to come.

The heat wave will bring triple-digit temperatures to the valleys and inland regions of Southern California as well as many parts of the rest of the state, heightening fire risks. It comes as parts of Northern and Central California are turning to water restrictions as the drought rapidly alters the landscape.

Key Reservoir On Colorado River Expected To Match Record Low

A key reservoir on the Colorado River is expected to dip to its record low Thursday in the latest showing of the drought’s grip on the region.

The surface elevation of Lake Mead along the Nevada-Arizona border is projected to be at 1071.61 feet (326.63 meters) — a measure that was hit in 2016. It’s the lowest level since Lake Mead was filled in the 1930s.

NorCal Conservationists Float Emergency Water Plan To Save Salmon

/in , /by /JPRby Sydney Dauphinais

After years of drought, salmon in Northern California are facing extinction. Conservation groups in the region have drafted a water management plan that, if adopted, would send less water to Central Valley farmers and keep more cold water for fish.

Last week, fishery advocates in Northern California submitted their temperature management plan to the State Water Resources Control Board. They want to change water operations in the Shasta, Trinity, Sacramento and Lower Klamath Rivers so the region’s salmon runs have enough cold water to survive.

How Capturing Floodwaters Can Reduce Flooding and Combat Drought

/in , , /by /Inside Climate Newsby Liza Gross

Farmers toil at the mercy of nature’s whims, which can prove particularly vexing in California.

Even before climate change, bouncing between drought and deluge was routine in the Central Valley, the state’s richest farming region. Humans have amplified these natural cycles by pumping greenhouse gases into the atmosphere, studies show, creating a future filled with what scientists recently dubbed “whiplash events.”

“Mega-Drought” Takes Dramatic Toll On Colorado River System That Provides Water to 40 Million People

/in , , /by /CBS News

Scientists are calling it a “mega-drought” brought on by climate change. The latest U.S. Drought Monitor Map shows large areas of the Southwest are “exceptionally dry,” the worst category. It’s taking a dramatic toll on the Colorado River system that provides water to 40 million people in seven states — and may force the federal government to make a drastic and historic decision. For more than eight decades, the iconic Hoover Dam has relied on water from Nevada’s Lake Mead to cover up its backside. But now, at age 85, it finds itself uncomfortably exposed. Much of the water the dam is supposed to be holding back is gone.

Carbon Dioxide in Atmosphere Reaches New High Despite Pandemic, Scripps Reports

/in , , /by /Times of San Diegoby Chris Jennewein

Atmospheric carbon dioxide measured at NOAA’s Mauna Loa Observatory peaked for 2021 in May at a monthly average of 419 parts per million, the highest level since accurate measurements began 63 years ago, Scripps Institution of Oceanography in San Diego reported Monday.

Scripps scientist Charles David Keeling initiated on-site measurements of carbon dioxide atop the volcano on the Big Island of Hawaii in 1958. NOAA began measurements in 1974, and the two research institutions have made complementary, independent observations ever since.
