drought – Page 4 – Desdemona Despair

A layer of dense smoke spread through much of Alberta during the week of 14 May 2023, caused by forest fires. The smoke that enveloped Calgary briefly gave the city one of the worst air-quality ratings in the world, as the fires to the north and west led to the evacuation of roughly 29,000 people across the province.

Alberta is on fire, but discussing climate change is taboo during 2023 election – “It’s very tough to talk about oil and gas in Alberta because it’s sort of the goose that lays the golden egg”

By Ian Austen 20 May 2023 (The New York Times) – When I arrived in Alberta recently to report an upcoming political story, there was no shortage of people wanting to talk about politics and the provincial election on May 29. But, even as wildfires flared earlier than usual and raged across an unusually wide […]

Lake Powell is rising more than a foot a day, but megadrought’s effects will still be felt – “It’s maybe a year’s worth of breathing room. The crisis is still very real and very much in front of us.”

By Scott Dance 11 May 2023 (The Washington Post) – Weeks after the surface of Lake Powell sunk to an all-time low, the key Colorado River reservoir is rising more than a foot a day — on track to deepen by some 70 feet in the coming months. Spring flows into the lake are among the […]

Western Mediterranean heatwave rare even for today’s warmed world – Extreme April 2023 heat in Spain, Portugal, Morocco, and Algeria almost impossible without climate change

7 May 2023 (Climate Centre) – A rapid study of last month’s extraordinary heatwave in the western Mediterranean by World Weather Attribution scientists says that while Europe and North Africa have experienced more extreme heat in recent years, the April heatwave was “so extreme that it is also a rare event in today’s warmer climate”. During the […]

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 […]
