"Arctic sea ice declined dramatically in 2007 and has never recovered. New research suggests the loss was a fundamental change unlikely to be reversed this century, if ever — perhaps proof of the sort of climate tipping point that scientists have warned the planet could pass as it warms."
"The Texas State Board of Education altered its internal guidance to schools last month to emphasize the “positive” aspects of fossil fuels in science textbooks."
"A cancer-causing chemical that is widely used to degrease aviation components and heavy machinery could also be linked to Parkinson’s disease, according to a new research paper that recommends increased scrutiny of areas long contaminated by the compound."
"Diplomats from nearly 200 nations and top climate scientists began a week-long huddle in Switzerland on Monday to distill nearly a decade of published science into a 20-odd-page warning about the existential danger of global warming and what to do about it."
"Last month, Brenda Foster stood on the railroad tracks at the edge of her yard in East Palestine, Ohio, and watched a smoky inferno billow from the wreckage of a derailed train. The chemicals it was carrying — and the fire that consumed them — were so toxic that the entire area had to evacuate."
Geothermal has long been hyped as the next big thing in renewable energy, but its breakthrough moment hasn’t happened yet. Barriers to expansion include the elusiveness of sites offering the magic trio of heat, water and permeability and concern for unique ecosystems. Contributor Jessica McKenzie on geothermal energy’s possibilities and challenges and the government funding that may finally fire it up.
"Particles in bushfire smoke can activate molecules that destroy the ozone layer, according to new research that suggests future ozone recovery may be delayed by increasingly intense and frequent fires."
"Sea ice in Antarctica shrank to the smallest area on record in February for the second year in a row, continuing a decade-long decline, the European Union's climate monitoring service said Tuesday."
Industrial hog farmers tout swine biogas as a clean, green energy source, but others point to its messy side. A young journalist who investigated the underreported stench of environmental racism associated with this technology learned valuable lessons along the way to producing a feature story that won her a Society of Environmental Journalists’ award for outstanding student reporting.
