Temperatures will soar well into the triple digits in the San Diego County deserts Tuesday and the blazing conditions are not expected to let up until this weekend, according to the National Weather Service.
UC San Diego researchers have confirmed that climate change helped produce the historic 43-day ocean heat wave that drew big crowds to San Diego beaches during the summer of 2018.
The finding was published in the Journal of Geophysical Research-Oceans, in a paper that says the phenomenon could not be solely attributed to natural variations in the weather.
Though the last couple of weekends have seen wet weather, it hasn’t been enough to keep up with the yearly average in time for summer in California. The Sierra Nevada snowpack, which is tested regularly by employees of the California Department of Water Resources, has yielded some grim results so far in 2020 in terms of snow-water equivalent.
On this edition of Your Call’s One Planet Series, we’re discussing a new study from Columbia University about an emerging climate-driven megadrought in the Western US.
Come spring, the American West’s vast water reservoirs are supposed to fill with melting snow. However this year, as in recent years, the large reservoirs of Lake Mead and Lake Powell in the Colorado River basin have seen declining water levels — an ominous trend that a new study warns could signal a looming megadrought.
On Monday, California fire officials gathered to launch the state’s annual Wildfire Preparedness Week. The message they delivered was clear: Summer 2020 would not mimic summer 2019, when wildfires mostly remained small and manageable into August.
Since 2000, the West has been stricken by a dry spell so severe that it ranks among the biggest “megadroughts” of the past 1,200 years. But scientists have found that unlike the decades-long droughts of centuries ago, this one has been supercharged by humanity’s heating of the planet.
Temperatures will reach well into the triple digits again Thursday in the San Diego County deserts, according to the National Weather Service. Conditions in the rest of the county will also remain warm, but will be slightly cooler than Wednesday.
A dry April caused the expected spring-summer runoff into Lake Powell to plunge dramatically, with the water-flow forecast down the Colorado River declining as much in one month as Tucson Water customers use in 10 years.
As summer descends on the U.S., public health experts are warning that the coronavirus could make intense heat waves deadlier, adding to the devastating death toll the country has suffered.
