Map of ensemble mean trends in ocean temperature and ice-shelf basal melting in the West Antarctic Ice Sheet (WAIS) for the Paris 2°C scenario. Temperature is averaged over the depth range 200–700 m. Trends are calculated at each point using annually averaged fields from 2006–2100. White regions indicate no significant trend. The Amundsen Sea region visualized here (latitude–longitude projection) is outlined in red in the inset map of Antarctica (polar stereographic projection). The black dashed line shows the 1,750 m depth contour of the continental shelf break and the blue dashed line outlines the continental shelf region used for analysis. Labels denote ice shelves (G, Getz; D, Dotson; Cr, Crosson; T, Thwaites; P, Pine Island; Co, Cosgrove; A, Abbot). Graphic: Naughten, et al., 2023 / Nature

The climate contradiction that will sink us – “We already have a refugee crisis; I shudder to think what would happen if everyone living within two meters of sea level would be displaced.”

By Zoë Schlanger 10 November 2023 (The Atlantic) – You’d be forgiven for thinking that the fight against climate change is finally going well. The clean-energy revolution is well under way and exceeding expectations. Solar is set to become the cheapest form of energy in most places by 2030, and the remarkable efficiency of heat pumps is driving their own uptake […]

Climate-driven extreme heat may make parts of Earth too hot for humans – “If temperatures continue to rise, we will live in a world where crops are failing and millions or billions of people are trying to migrate because their native regions are uninhabitable”

By Aaron Wagner 9 October 2023 UNIVERSITY PARK, Pa. (PennState) – If global temperatures increase by 1 degree Celsius (C) or more than current levels, each year billions of people will be exposed to heat and humidity so extreme they will be unable to naturally cool themselves, according to interdisciplinary research from the Penn State […]

The Mississippi River is losing its fight with the ocean – “This is not a one-off or once-in-100-years thing”

By Nancy Walecki 11 October 2023 (The Atlantic) – The mouth of the Mississippi River is the arena for a kind of wrestling match. In one corner of the ring is the salt water of the Gulf of Mexico, and in the other, the river’s fresh water. The two shove against each other, and usually, […]

Drought drains Brazilian Amazon residents reliant on waterways – “It’s every man for himself”

By Orlando Junior 3 October 2023 (AFP) – Not far from the emblematic site where the black waters of the Rio Negro join the brown currents of the Solimoes, two chief tributaries of the Amazon, what once was a lake has given way to a vast stretch of cracked mud. Now, the only water remaining […]

Geographical pattern of the primary drivers of deteriorating status among amphibians. a,b, The primary drivers of deteriorating status among amphibians during 1980–2004 (482 species; a) and 2004–2022 (306 species; b). Cell colour was determined by the primary driver impacting the most species. Where two primary drivers equally contribute to a cell, an intermediate colour is shown. The stars indicate where the primary driver is undetermined or there are numerous primary drivers. The cell area is 7,775 km2. Graphic: Luedtke, et al., 2023 / Nature

Climate change emerges as major driver of amphibian declines, new research finds – “It’s a gut punch and an awakening”

By JoAnn Adkins 4 October 2023 (FIU) – Amphibians are in trouble and in desperate need of conservation action, according to a new global assessment of the world’s amphibian population. Salamanders are experiencing the greatest decline in numbers, but frogs, toads, newts, and salamanders throughout the Neotropics — extending from South Florida and Caribbean islands […]

In Texas, water levels are so low a rarely-seen underwater cave and century-old ruins have appeared – “I haven’t seen the water this low since I moved here. It’s actually kind of sad.”

By Amanda Jackson and Zoe Sottile30 September 2023 (CNN) – Water levels are so low at Canyon Lake in Texas that an underwater cave and remnants of communities that stood more than a century ago at the site are reappearing. The lake, located in Comal County just northeast of San Antonio, is a man-made lake spanning 8,200 acres with […]
