Spain records hottest and driest April on record – “This is the worst period that we have had for the last 100 years”

MADRID, 8 May 2023 (AP) – Drought-stricken Spain says last month was the hottest and driest April since records began in 1961. The State Meteorological Agency, known by the Spanish acronym AEMET, said Monday the average daily temperature in April was 14.9 degrees Celsius (58.8 Fahrenheit), that is 3 degrees Celsius above the average. AEMET […]

Tulare Lake flooding due to snowpack melt seen from space – “The state has both too much water and not enough”

By Jess Thomson 5 May 2023 (Newsweek) – The long-dried basin of Lake Tulare in California has rapidly refilled in the wake of intense rainfall and snowmelt. The speed and scale of the southern San Joaquin Valley lake’s return can be seen in images taken from space by the Operational Land Imager (OLI) on NASA‘s Landsat […]

Climate change made East Africa’s drought 100 times more likely, study says – “This vital study shows that climate change is not just something our children need to worry about – it’s already here”

By Raymond Zhong 27 April 2023 (The New York Times) – Two and a half years of meager rain have shriveled crops, killed livestock and brought the Horn of Africa, one of the world’s poorest regions, to famine’s brink. Millions of people have faced food and water shortages. Hundreds of thousands have fled their homes, seeking relief. […]

WMO annual report highlights continuous advance of climate change – “While greenhouse gas emissions continue to rise and the climate continues to change, populations worldwide continue to be gravely impacted by extreme weather and climate events”

Geneva, 21 April 2023 (WMO) – From mountain peaks to ocean depths, climate change continued its advance in 2022, according to the annual report from the World Meteorological Organization (WMO). Droughts, floods, and heatwaves affected communities on every continent and cost many billions of dollars. Antarctic sea ice fell to its lowest extent on record […]

Global rice shortage in 2023 is set to be the biggest in 20 years – “At the global level, the most evident impact of the global rice deficit has been, and still is, decade-high rice prices”

By Lee Ying Shan 18 April 2023 (CNBC) – From China to the U.S. to the European Union, rice production is falling and driving up prices for more than 3.5 billion people across the globe, particularly in Asia-Pacific – which consumes 90% of the world’s rice. The global rice market is set to log its largest […]

Physiological response curves may shift as soil microbiomes respond to drought. In the short term (minutes to days), physiological acclimation may help to sustain function, such as soil carbon decomposition. Over weeks to decades, community shifts and evolution could alter response curves to maintain functioning under dry conditions. Broken lines indicate potential variation in the breadth of the shifted response curves. Graphic: Evans, et al., 2022 / Functional Ecology

Droughts destroying Earth’s biggest carbon sink on land: study – If more carbon-releasing microbes survive than carbon-sequestering microbes, we could end up with carbon-depleted soils

By Mark Waghorn 12 April 2023 (SWNS) – Droughts are destroying Earth’s biggest carbon sink on land, according to new research. Soil stores more greenhouse gas than plants and the atmosphere combined – thanks to the microbes that live in it. Moisture plays a key role in the process. Lack of rainfall is disrupting this […]

A wet winter won’t stave off the Colorado River’s water cuts – “There are discussions going on but they’re not making much progress. The level of distrust and animosity is really remarkable.”

By Joshua Partlow 3 April 2023 GRAND JUNCTION, Colorado (The Washington Post) – The abundant snow in the Rocky Mountains this year has been a welcome relief, but is not enough to overcome two decades of drought that has pushed major reservoirs along the Colorado River down to dangerous levels, Camille Calimlim Touton, the commissioner […]

Population histories for all species of California salmon to 2021. On 6 April 2023, the Pacific Fishery Management Council, a quasi-federal body that oversees West Coast fisheries, finalized a decision to recommend closing the salmon season spring of 2024, due to years of drought conditions.

Years of drought force shutdown of salmon fishing season off California

By Dino Grandoni 6 April 2023 (The Washington Post) – Years of drought have taken such a toll on California’s fall run of Chinook salmon that, for the first time in 14 years, fishery managers are canceling next year’s fishing season off the state’s coast to help the population recover. The Pacific Fishery Management Council, […]

California’s snowpack is melting faster than ever before, leaving less available water – “The threats to the state’s water supply are imminent”

By Hayley Smith 14 February 2023 (Los Angeles Times) – For decades, Californians have depended on the reliable appearance of spring and summer snowmelt to provide nearly a third of the state’s supply of water. But as the state gets drier, and as wildfires climb to ever-higher elevations, that precious snow is melting faster and […]

Munich Re: Climate change and La Niña driving losses – “Climate change is taking an increasing toll. The natural disaster figures for 2022 are dominated by events that, according to the latest research findings, are more intense or are occurring more frequently.”

10 January 2023 (Munich Re) – With overall losses of around US$ 270bn (previous year US$ 320bn) and insured losses of roughly US$ 120bn (previous year US$ 120bn), 2022 joins the recent run of years with high losses. Overall losses were close to the average for the last five years, while insured losses were significantly […]
