Determining how climate change is affecting water supplies is difficult in a state like California that swings between floods and droughts, but a new study has found that climate models agree on key metrics that could help water managers in the Golden State.
Cities across the U.S. Southwest recorded their driest monsoon season on record this year, some with only a trace or no rain.
The seasonal weather pattern that runs from mid-June and ended Wednesday brings high hopes for rain and cloud coverage to cool down places like Las Vegas and Phoenix. But like last year, it largely was a dud, leaving the region parched.
Climate change is affecting natural resources in California, with water being one of the most important in the state. Water source is critical for municipalities, agriculture, industry, and habitat/environmental purposes. Will future supply meet future demand? How will the economic value of water change over this century?
The National Weather Service says that conditions are in place for a La Niña weather pattern in the fall and winter of 2020-21. That could bring warmer, drier than usual weather to San Diego over the next few months.
By definition, La Niña happens when the water along the equator is colder than usual. That pushes the jet stream farther north and directs storms away from the Pacific Southwest region of the United States.
The autumn equinox was at 6:30 a.m. PDT on Tuesday, meaning there are nearly equal periods of daylight and darkness. From now until the winter solstice in December, days will gradually get shorter and nights will get longer in the Northern Hemisphere.
Building upon more than two decades of research, a new web-based platform called OpenET will soon be putting NASA data in the hands of farmers, water managers and conservation groups to accelerate improvements and innovations in water management. OpenET uses publicly available data and open source models to provide satellite-based information on evapotranspiration (the “ET” in OpenET) in areas as small as a quarter of an acre and at daily, monthly and yearly intervals.
San Diego County will open an erosion control center in Alpine Thursday to help businesses and homeowners prevent debris flows in the areas burned by the Valley Fire.
Message to Democrats: Just because President Trump says it, that doesn’t necessarily mean it’s wrong.
Yes, our president habitually fantasizes, distorts and lies. But to borrow an old cliché, even a broken clock is right twice a day.
One important example: Trump’s widely ridiculed comment that California needs to “rake the floor” of its forests better.
The Colorado River’s largest reservoirs are expected to keep struggling over the next five years due to climate change, according to the federal agency that oversees them.
The Bureau of Reclamation’s new modeling projections, which include this year’s record-breaking heat and dryness in some parts of the southwestern watershed, show an increasing likelihood of an official shortage declaration before 2026.
If dry conditions like the Colorado River Basin has seen since 2000 persist, the agency’s model shows an almost 80% chance of seeing an official shortage declaration by 2025. The chance of seeing the reservoir drop to a critically low level is about 20% in that same time period.
For the second time in two years, federal officials are warning that Lake Mead could drop in five to six years to levels low enough to possibly warrant major Central Arizona Project water cutbacks to Tucson and Phoenix.
These warnings were ratcheted up significantly compared to forecasts made earlier this year. That’s due to the severely hot and dry weather that struck most of the West during the summer, including the hottest two months on record in Tucson and Phoenix in August and July, respectively.
