14+ hour, 37+ min ago   (1028+ words) Drilled cores from Galápagos coral carry an ocean temperature record back to the year 1000, and recent decades break the pattern. When the tropical Pacific warms every few years, the weather turns strange thousands of miles away. Direct measurements of that…...

18+ hour, 25+ min ago   (1015+ words) Lakes across northern North America buried carbon at a steady rate for thousands of years, but that changed dramatically after 1850. Leaves, pollen and washed-in soil sink to the bottom of a lake and settle into mud, and the carbon in…...

2+ day, 12+ hour ago   (1043+ words) Coral reefs are under growing heat stress, but a new field test suggests researchers may have another tool to help them cope. Coral probiotics have worked in tanks for years, where a researcher controls the water and decides when the…...

2+ day, 17+ hour ago   (880+ words) Ancient wildfires may have inspired pottery by showing early farmers how fire could transform ordinary clay into a hard, durable material. Long before anyone deliberately shaped a bowl, a stretch of ancient wildfires may have quietly handed early farmers the…...

2+ day, 16+ hour ago   (980+ words) Planting trees in snowy regions can reduce their climate benefit because dark forest canopies absorb sunlight that bright snow would reflect. Forest trees pull carbon out of the air, so Canada pays to plant them. In snow country, the land…...

2+ day, 22+ hour ago   (574+ words) A 22% drop in butterfly populations from 2000 to 2020 signals a troubling, widespread decline across the broader pollinator community. Scientists count butterflies more thoroughly than any other insect, which makes them an early-warning system for the health of other animal species that…...

2+ day, 22+ hour ago   (1005+ words) Overlooked ocean foods such as oysters, mussels, shrimp and other invertebrates deliver surprisingly large amounts of essential vitamins and minerals. Fisheries and fish farms report their output in tons, which measures how much food there is but not what’s in…...

3+ day, 16+ hour ago   (1027+ words) Methane in Arctic glacier rivers on Svalbard came from ancient shale, not microbes, and the yearly total is tiny next to what people emit. A glacier melts from the top, and the water runs off in rivers barely above freezing....

3+ day, 14+ hour ago   (727+ words) Satellite data reveal that much of the Amazon's regrowing forest is young, fragmented, and vulnerable, despite strong connections to intact forest. A new satellite-based analysis has taken the first biome-wide look at how the Amazon’s regrowing forests are actually faring....

3+ day, 16+ hour ago   (798+ words) Greenland ice reveals a surprising shift in industrial pollution after 1990 that could help explain recent Arctic warming. Buried deep in the Greenland ice sheet is a chemical diary of a century of industrial pollution, and the entries after 1990 don’t add…...
