The fingerprints of climate change are all over the intense heat waves gripping the globe this month, a new study finds. Researchers say the deadly hot spells in the American Southwest and Southern Europe could not have happened without the continuing buildup of warming gases in the air.
There are no lush green lawns among the rows of single-family homes that line a quiet boulevard a mile west of the University of Arizona campus. Instead, small lizards scurry across gravel to the shade of cacti, shrubs and trees native to the Southwestern desert, as cicadas drone and backyard chickens cluck in the triple-digit heat now common here in July.
Widespread heat has shattered records from coast to coast throughout the first half of summer, but the longest days of 2023 are in the rearview mirror and cooler weather is on the horizon.
With the phrase “heat dome” entering our vocabulary and more than 2,300 heat records smashed so far this summer, extreme temperatures are endangering our lives. And for farmers, the scorching hot, dry weather also threatens their livelihoods.
The state is sending millions to farmers throughout the San Joaquin Valley to keep water in the ground.
The money, paid through the LandFlex program, goes to groundwater sustainability agencies (GSAs) and then directly to farmers, paying them for every acre foot they don’t pump.
The water temperature around the tip of Florida has hit triple digits — hot tub levels — two days in a row. Meteorologists say it could be the hottest seawater ever measured, although some questions about the reading remain.
Although the West is still enjoying the effects of an exceptionally wet winter, climate experts say that extreme heat waves will continue chipping away at the benefits. Just 9.5% of California and Nevada remained in drought on July 20, compared to 99% at the beginning of the water year in October 2022. Drought conditions persist in areas that did not receive this past winter’s deluge, including parts of southeastern California and southern Nevada.
Google just published its 2023 environmental report, and one thing is for certain: The company’s water use is soaring. The internet giant said it consumed 5.6 billion gallons of water in 2022, the equivalent of 37 golf courses. Most of that — 5.2 billion gallons — was used for the company’s data centers, a 20% increase on the amount Google reported the year prior.
The Colorado River Basin – the area drained by the Colorado River and its tributaries – covers approximately 647,500 square kilometers (250,000 square miles) in seven states across western United States, supplying water to about 40 million people while supporting agriculture and natural ecosystems. According to a new study conducted by the University of California, Los Angeles (UCLA), from 2000 to 2021, climate change caused the loss of over 40 trillion liters (10 trillion gallons) of water in this basin.
They’re back! Arising out of their dusty/muddy/sandy graves, the zombie lakes of California are reclaiming their own. For geologic ages, they have lain there, undead — well, often drought-dry, and not their original saturated selves. But now the monumental rains of this winter and spring filled them and then some, reminding us of California’s paleo-hydrology, our ancient lakes and waterways.
