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 […]

On frontier of new “gold rush” quest for coveted EV metals yields misery – “I am frustrated. But even more than that, I have lost hope.”

By Rachel Chason and Chloe Sharrock 27 April 2023 KAGBANI, Guinea (The Washington Post) – One of the poorest countries on Earth has become a crucial player in the world’s green-energy transition. Guinea, a West African nation of more than 13 million people, is home to the world’s biggest reserves of bauxite — a reddish-brown […]

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 […]

Video: Sargassum seaweed hits Florida Keys beaches

By Richard Burkard 17 April 2023 (Knewz) – It sounds like a B-grade movie title: The approach of the 10-million pound blob. Yet it’s real, and it’s forcing swimmers and owners of beachfront property in Florida to take action. Knewz noted in late March that a giant mass of sargassum seaweed was spotted from space. It […]

Map showing the physical imprint and consequences of extreme summer heat across the Pacific Northwest in 2021. The June-August (JJA) 2021 seasonally averaged temperature anomalies (t2m) over North America calculated from the 1951-1980 mean of ERA5 Reanalysis, with the Pacific Northwest region (PNW; 42–53 °N, 124–115 °W, dark blue box) highlighted. The year 2021 (dashed black line) is shown relative to the distribution (black line) and probability density (red line) curves of JJA t2m values over the period 1950–2021 for the PNW region. White exes indicate the locations of all tree-ring chronology predictors used in the subsequent JJA t2m reconstruction. Graphic: Heeter, et al., 2023 / npj Climate and Atmospheric Science

The summer of 2021 was the Pacific Northwest’s hottest in a millennium – “The tree scorch was shocking. The average summer temperatures were extraordinarily away from the norm.”

By Sid Perkins 14 April 2023 (Science News) – A two-week-long heat wave in the Pacific Northwest in 2021 helped make that summer a record breaker for the region (SN: 7/7/21). Now, tree ring data from the area’s forests reveal that the summer of 2021 was also the region’s hottest of the last millennium. The average temperature […]

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 […]
