GENEVA (AP) — The U.N. weather agency is sounding a “red alert” about global warming, citing record-smashing increases last year in greenhouse gases, land and water temperatures and melting of glaciers and sea ice, and warning that the world's efforts to reverse the trend have been inadequate. “The latest State of the Global Climate report shows a planet on the brink. Fossil fuel pollution is sending climate chaos off the charts.”The latest WMO findings are especially stark when compiled in a single report. WMO said the impact of heatwaves, floods, droughts, wildfires and tropical cyclones, exacerbated by climate change, was felt in lives and livelihoods on every continent in 2023. And so, nothing gets done.”___Borenstein reported from Washington, D.C.___The Associated Press’ climate and environmental coverage receives financial support from multiple private foundations.

☆ Gardeners are fuming about a study that found produce from urban farms has a high carbon footprint

Fruits and vegetables grown on urban farms have on average six times the carbon footprint of produce from conventional farms, the study, which was published in the peer-reviewed journal Nature Cities , found. Hawes said that produce grown on 17 out of the 73 urban farms his team studied across five countries had lower carbon footprints than produce from conventional farms. Rushdan also argued that urban farms are a much more sustainable use of land than commercial or industrial development. The letter also alluded to the structural problems that can prevent urban farms from being more permanent, including commercial development and barriers to landownership. "Our work does not lessen the many benefits that urban agriculture provides," Hawes said in an email.

☆ ‘Hot drought’ in the West is unprecedented in at least 5 centuries, study suggests

CNN —The West’s recent heat-driven megadroughts are unprecedented in at least 500 years, new research shows. “Hot drought” — when extreme drought and heat occur simultaneously — has increased in severity and frequency over the last century due to human-caused climate change, according to a study published Wednesday in the journal Science Advances. While the previous study measured the length and width of the tree rings to gauge drought conditions, King’s research analyzed the density of the rings to measure how temperatures changed over time. “More dense rings mean warmer temperatures, and less dense rings mean cooler temperatures, typically,” King explained. “Water security and wildfire will become bigger problems until climate change is stopped,” said Overpeck, who was not involved with the study but has done research on hot droughts.

☆ How much water is left in the Colorado River? Scientists and officials are scrambling to find out

It’s a remarkable turnaround that will give back billions of gallons of Colorado River water to millions of people in the Southwest, primarily in Arizona and Nevada. Snow-covered peaks near the headwaters of the Colorado River outside Winter Park, Colorado, in March. Scientists estimate that Colorado River flows have decreased by about 20% compared to the early 20th century. “There are tough choices ahead,” Becky Mitchell, the Colorado commissioner for the Upper Colorado River Commission, told CNN. Bill Hasencamp, the manager of Colorado River Resources for the Metropolitan Water District of Southern California.

“From Day 1, President Biden has treated climate change with the urgency it requires,” Ms. Jean-Pierre said, pointing to measures like the Inflation Reduction Act, the most significant climate law in history. With research showing that recent heat waves in the United States and Europe would have been “virtually impossible” without the influence of man-made climate change, many climate experts said Mr. Biden needed to take a strong stand against new fossil fuels. Activists have long pushed Mr. Biden to do so, but the White House has expressed worries in the past about its authority to take such unilateral measures, fearing that they might be overturned in the courts. Instead, Ms. Jean-Pierre pointed to the ongoing benefits of the Inflation Reduction Act, which Mr. Biden signed into law last year but whose funding will continue flowing for years to come. It contains nearly $370 billion in tax credits to spur wind and solar power and electric vehicle battery manufacturing in the United States and incentives for purchases of electric vehicles, induction stoves and electric heat pumps.
