29 May 2023 (UN News) – Hunger is set to worsen in 18 “hotspots” worldwide including Sudan, where fighting is putting people at risk of starvation, the Food and Agriculture Organization (FAO) and the World Food Programme (WFP) warned in a report published on Monday. Sudan, Burkina Faso, Haiti and Mali have been elevated to the highest alert level, joining Afghanistan, Nigeria, […]

Southern China swelters, power grids struggle under “relentless” heatwaves – Pigs, rabbits, and fish dying from searing temperatures – “It’s just been week on week on week of these records being shattered”

By David Kirton 2 June 2023 BEIJING (Reuters) – Heatwaves tormenting parts of southern and eastern China are set to persist through June, putting power grids under strain as air conditioners are turned on full blast at homes, offices and factories in mega-cities like Shanghai and Shenzhen. In the next three days, most of southern […]

Cracks emerging in Europe’s united front to battle climate change – “You can’t say I support the Green Deal, but not the ambition to restore nature. It’s not ‘à la carte menu.’”

By Samuel Petrequin 27 May 2023 BRUSSELS (AP News) – The European Union has been at the forefront of the fight against climate change and the protection of nature for years. But it now finds itself under pressure from within to pause new environmental efforts amid fears they will hurt the economy. With the next European […]

Flood insurance costs to soar in Florida – In the most expensive ZIP code for flood insurance in South Florida, average premiums will rise above $7,000 per year

By Nicolas Rivero 21 May 2023 (WUSF) – Brace for a few years of flood insurance rate hikes, South Florida. And they’re going to be steep — doubling, even tripling for thousands of homeowners. FEMA has changed the way it calculates flood insurance prices. Instead of relying on old flood zone maps covering broad areas, […]

Thousands evacuated as Philippines warns of flooding, landslides from approaching Typhoon Mawar

By Jim Gomez 29 May 2023 MANILA, Philippines (AP News) – Philippine officials began evacuating thousands of villagers, shut down schools and offices and imposed a no-sail ban Monday as Typhoon Mawar approached the country’s northern provinces a week after battering the U.S. territory of Guam. The typhoon is packing maximum sustained winds of 155 […]

Black symbols show estimates ± calculated total uncertainty made using joint mooring-model-hydrographic method (square/triangle/circle symbols, 84° E/140° E/170° E; equation (2), Extended Data Fig. 7 and Supplementary Section 2). White symbols show comparative estimates from other studies11,24,47,48,49,50 (Supplementary Table 3). Blue line, total volume transport for time periods of 1994–1996, 2007–2011 and 2016–2018, which estimates the strength of the lower limb of overturning circulation in the Australian Antarctic Basin (shading shows total error of 1.2 Sv; Supplementary Table 2). b, Oxygen transport. Black line, total oxygen transport that estimates abyssal ventilation ± total uncertainty of 290 Sv mol kg−1 (equation (3)). c, Comparison of lower limb of overturning circulation and shelf salinities from a site of DSW formation in Ross Sea (Terra Nova Bay; refs. 12,13,35). Dotted blue arrows show declining trend in overturning for 1994–2009 and 1994–2017 that have uncertainties of ±0.5 Sv decade−1. Graphic: Gunn, et al., 2023 / Nature Climate Change

Deep ocean currents around Antarctica headed for collapse – “Such profound changes to the ocean’s overturning of heat, freshwater, oxygen, carbon, and nutrients will have a significant adverse impact on the oceans for centuries to come”

By Kathy Gunn, Matthew England, and Steve Rintoul 25 May 2023 (The Conversation) – Antarctica sets the stage for the world’s greatest waterfall. The action takes place beneath the surface of the ocean. Here, trillions of tonnes of cold, dense, oxygen-rich water cascade off the continental shelf and sink to great depths. This Antarctic “bottom […]

Global loss of biodiversity is significantly more alarming than previously suspected – “Almost half of animals on Earth for which assessments are available are currently declining. To make matters worse, many of the animal species that are thought to be non-threatened from extinction are in fact progressively declining”

23 May 2023 (Queen’s University Belfast) – A new study led by researchers from Queen’s University Belfast has shown that the global loss of biodiversity caused by human industrialisation is significantly more alarming than previously thought. The global-scale analysis has been published in the journal Biological Reviews. The study looked at changes in the population densities […]

Estimated conifer vegetation climate mismatch (VCM) in the Sierra Nevada (2015-2020). (a) The conifer HSM projected to contemporary climate and overlayed on the modern conifer distribution (EVeg) reveals that up to 19.5% of modern conifer forest is in VCM, primarily along the low-elevation western slope of the Sierras. The total area of conifers shown is 40,495 km2, of which ∼32,500 km2 are in equilibrium with the modern climate. (b) Mean Temperature of Wettest Quarter and Mean Annual Precipitation were the most important predictors in the HSM (meanMTWQ = 0.518, SEMTWQ = 0.209 and meanMAP = 0.418, SEMAP = 0.139). Standard error bars are included in the barplot. (c) Boxplots show the difference between modern (2015–2020) and historical (1915–1955) climate within the conifer VCM regions. Change in climate is calculated as the number of standard deviations the modern climate differs from the historical period. Though the differences were statistically significant for each climate variable (p < 8.45 × 10−12, independent t-test), Precipitation of Driest Month showed the greatest decrease (mean = −2.41, SD = 2.84) and MTWQ the greatest increase (mean = 1.59, SD = 0.329) between the historical and modern climate. Mean Annual Precipitation changed the least within the VCM area (mean = 0.165, SD = 0.395). Boxplots include the median line, a box denoting the interquartile range, and whiskers showing values ±1.5 × the interquartile range. Graphic: Hill, et al., 2023 / PNAS Nexus

Researchers are discovering “zombie forests” in new places across the western U.S. – “Our maps force some critical – and difficult – conversations about how to manage impending ecological transitions”

By Brendan O’Leary 13 May 2023 (The Cool Down) – It’s no secret that our warming atmosphere has resulted in extreme weather all over the world, but there’s also a less noticeable consequence at work as well. Rising ambient temperatures mean that thousands of coniferous forests in California will be unable to replenish their numbers once they die. What […]

Accelerated melting of glaciers in Greenland – Greenland’s glaciers have lost at least 587 cubic km of ice over the last century

26 May 2023 (University of Leeds) – A study has found widespread mass loss of glaciers and ice caps in Greenland since the start of the 20th century. The research provides critical insights into long-term changes to the glaciers and ice caps as a result of climate change, which has contributed about one fifth to […]

Insurance giant State Farm halts sale of new home policies in California due to wildfires – “State Farm General Insurance Company made this decision due to historic increases in construction costs outpacing inflation, rapidly growing catastrophe exposure, and a challenging reinsurance market”

By Gloria Oladipo 27 May 2023 (The Guardian) – The insurance giant State Farm, America’s biggest car and home insurer by premium volume, will halt the sale of new home insurance policies in California, citing wildfire risk and inflation of construction costs. Starting on Saturday, the company will not accept insurance applications for business and personal lines […]
