Humans are disrupting natural “salt cycle” on a global scale

31 October 2023 (University of Maryland) – The influx of salt in streams and rivers is an ‘existential threat,’ according to a research team led by a UMD geologist. The planet’s demand for salt comes at a cost to the environment and human health, according to a new scientific review led by University of Maryland Geology Professor Sujay Kaushal. Published […]

Transition minerals: A climate solution that could cost the earth – “We need a just, fair, and equitable transition from fossil fuels to renewables”

10 July 2024 (Global Witness) – Renewable energy is often hailed as a panacea for the energy crisis. But without better consultation and regulation, plans to expand mining for minerals central to the energy transition could be disastrous for people and the planet. To tackle the climate crisis, we need to transition away from fossil […]

Microplastics found in every human semen sample tested in study – “There is a need for action to avoid additional permanent damage to the planet and the human body”

By Damian Carrington 10 June 2024 (The Guardian) – Microplastic pollution has been found in all human semen samples tested in a study, and researchers say further research on the potential harm to reproduction is “imperative”. Sperm counts in men have been falling for decades and 40% of low counts remain unexplained, although chemical pollution has been implicated by many […]

Maps of near-bottom dissolved oxygen in the continental shelf waters off the United States Pacific Northwest, 1950-2021. About half of the water near the seafloor off the Pacific Northwest coast experienced low-oxygen conditions in 2021. Data from 1950 to 1980 are from the World Ocean Database32, data from 2009–2018 are from the NOAA Groundfish survey, and data from 2021 are from this study.

Pacific Northwest coast suffers from low oxygen, study finds – “As we keep changing the climate, it’s going to become the norm. What’s pretty remarkable is that 50 percent of the continental shelf is going to be low oxygen.”

By Amanda Zhou 10 June 2024 (The Seattle Times) – About half of the water near the seafloor off the Pacific Northwest coast experienced low-oxygen conditions in 2021, according to a new study. And those hypoxic conditions, which are expected to become common with global warming, threaten the food web, the study found. The study […]

Joshua trees, such as this 25-foot-tall specimen that is 150 to 200 years old, are threatened with removal for a solar project in Boron by Avantus, a California company that is mostly owned by KKR, the global private equity firm. Thousands of protected Joshua trees just outside this desert town, including many thought to be a century old, will be cut down to make way for the sprawling solar project. Residents worry that construction dust will spread valley fever. Photo: Myung J. Chun / Los Angeles Times

Solar project to destroy thousands of Joshua trees in the Mojave Desert – “Let’s destroy the environment to save the environment”

By Melody Petersen 31 May 2024 BORON, California (Los Angeles Times) – A renewable energy company will soon begin clearing thousands of protected Joshua trees just outside this desert town, including many thought to be a century old, to make way for a sprawling solar project that will generate power for 180,000 homes in wealthier […]

Diagrams showing parameters for the collapse of the Atlantic Meridional Overturning Circulation (AMOC). (A) The AMOC strength at 1000 m and 26°N, where the yellow shading indicates observed ranges (60, 61). The cyan-colored lines indicate the magnitude of FH. The red arrow indicates the AMOC tipping point (model year 1758; fig. S1, A and B), and the blue sections indicate the 50-year periods used in (B) to (D). Inset: The hosing experiment where fresh water is added to the ocean surface between 20°N and 50°N in the Atlantic Ocean (+FH) and is compensated over the remaining ocean surface (−FH). The black sections indicate the 26°N and 34°S latitudes over which the AMOC strength and freshwater transport (FovS) are determined, respectively. (B to D) AMOC streamfunction (Ψ) and Atlantic meridional heat transport (MHT; see also fig. S2) for model years 1 to 50, 1701 to 1750, and 2151 to 2200. The contours indicate the isolines of Ψ for different values. Graphic: Van Westen, et al., 2024 / Science Advances

Marker for the collapse of key Atlantic current discovered – “We are approaching the tipping point”

By Stephanie Pappas 9 February 2024 (Live Science) – Scientists have discovered a key warning sign before a crucial Atlantic current collapses and plunges the Northern Hemisphere into climate chaos. The Atlantic Meridional Overturning Circulation (AMOC) carries warm water north from the Southern Hemisphere, where it releases heat and freezes. The freezing process concentrates salt […]
