Lakes Growing Globally as Ice Melts and Reservoirs Expand

/in , /by /Yale Environment 360

Over the last four decades, the area covered by lakes globally has grown by close to 18,000 square miles, an expanse nearly twice the size of Lake Erie. Scientists used satellite imagery and artificial intelligence to map 3.4 million lakes around the world between 1984 and 2019, finding that lake area grew as reservoirs expanded and rising temperatures melted glaciers and permafrost, particularly in Greenland, the Rocky Mountains, and the Tibetan Plateau.

Limiting Global Warming Now Can Preserve Valuable Freshwater Resource

Snowcapped mountains not only look majestic — They’re vital to a delicate ecosystem that has existed for tens of thousands of years. Mountain water runoff and snowmelt flows down to streams, rivers, lakes, and oceans — and today, around a quarter of the world depends on these natural “water towers” to replenish downstream reservoirs and groundwater aquifers for urban water supplies, agricultural irrigation, and ecosystem support.

United States of Megadrought

Drought has engulfed large swaths of the country, threatening parts of the nation’s food and power supply. And it’s getting worse.

More than 80 percent of the continental U.S. is experiencing unusually dry conditions or full-on drought, which is the largest proportion since the National Oceanic and Atmospheric Administration began tracking 20 years ago.

A New Comprehensive Assessment of Ocean Warming Highlights Future Climate Risks

/in , /by /Phys.orgby Chinese Academy of Sciences

A research study just published in Nature Reviews Earth & Environment provides new information about how much the planet has warmed and what warming we may expect in the coming decades. This study is important because it motivates us to take actions to mitigate and respond to climate change. It shows what will happen if we don’t take action to slow global warming.

California Might Get Hit by a Rainstorm. It All Depends on These Two Weather Patterns

/in , /by /San Francisco Chronicleby Gerry Diaz

From record-breaking heat waves to historic rainstorms, September was nothing short of a meteorological roller-coaster ride and the Bay Area was given a front-row seat.

This roller coaster of temperatures and intense back-and-forth between extreme heat and strong rains has come to a halt, though. A quiet, mostly dry pattern looks to be taking center stage for October as California is set to enter its third consecutive year of La Niña. But another weather pattern could shake up our chances of seeing at least one more storm roll into California before the end of the month.

100 Years After Compact, Colorado River Nearing Crisis Point

/in , , /by /Associated Pressby Chris Outcalt and Brittany Peterson

The intensifying crisis facing the Colorado River amounts to what is fundamentally a math problem.

The 40 million people who depend on the river to fill up a glass of water at the dinner table or wash their clothes or grow food across millions of acres use significantly more each year than actually flows through the banks of the Colorado.

In fact, first sliced up 100 years ago in a document known as the Colorado River Compact, the calculation of who gets what amount of that water may never have been balanced.

Record high temperatures in urban Europe as heat waves bake the planet more often. Devastating floods, some in poorer unprepared areas. Increasing destruction from hurricanes. Drought and famine in poorer parts of Africa as dry spells worsen across the globe. Wild weather worldwide getting stronger and more frequent, resulting “in unprecedented extremes.”

Rains, Mudslides Prompt Southern California Evacuations

/in , /by /Associated Pressby Stephanie Dazio

Thousands of residents were under evacuation and shelter-in-place orders early Tuesday after heavy rains unleashed mudslides in a mountain area east of Los Angeles that burned two years ago, sending boulders and other debris across roads.

Firefighters went street by street in the community of Forest Falls Monday night to make sure no residents were trapped. Eric Sherwin, spokesperson for the San Bernardino County Fire Department, said crews hadn’t found anyone who needed to be rescued and no one was reported missing. Crews would canvas the neighborhoods again and begin cleanup efforts after sunrise, he said.

Carlsbad Desal Plant Water Output Cut 20% to Conserve Power Amid Heat Wave

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

Water production at the Carlsbad desalination plan has been temporarily reduced to conserve power while the heat wave stresses California’s electric grid.

The Claude “Bud” Lewis Carlsbad Desalination Plant, which can produce up to 50 million gallons per day, typically accounts for about 1% of peak electricity demand in San Diego Gas & Electric’s service area.

California’s Climate Makes It Especially Vulnerable to Global Warming

/in , , /by /The New York Timesby Soumya Karlamangla

The allure of California has long been its almost unbelievably good weather: predictably dry summers and pleasant, if occasionally rainy, winters. Who wouldn’t want to escape swampy heat for this temperate paradise? Our typically agreeable weather (current heat wave notwithstanding) is officially called a Mediterranean-type climate, defined as having cool, wet winters and dry, warm summers.
