2+ mon, 2+ week ago (847+ words) Environmental regulations are easy to attack in the abstract. They cost money, impose restrictions, and their benefits tend to be diffuse and hard to see. A new study makes those benefits visible in a way that’s hard to argue with....
Rain crosses an invisible line and Earth’s soils start leaking nutrients in a new way
3+ mon, 1+ week ago (810+ words) Wet soil grips nitrogen, and dry soil leaks it. That basic rule of soil nitrogen loss appears in ecosystems on every continent, and few researchers had reason to question it. However, there turns out to be a catch. Researchers studying…...
Scientists may have solved the long-standing mystery of Blood Falls, the glacier that 'bleeds' red water in Antarctica
3+ mon, 3+ week ago (887+ words) Blood Falls is an outflow of iron-rich, hypersaline water that seeps from beneath Taylor Glacier in Antarctica’s McMurdo Dry Valleys. Its striking red color is caused by iron oxides forming when the ancient, oxygen-free brine contacts air. Scientists have now…...
Beavers are getting a longer work season as temperatures rise
4+ mon, 6+ day ago (400+ words) Beavers in Canada are emerging earlier from winter ice as warming temperatures shorten ice seasons, increasing conflicts with humans....
Predicting rainfall is getting harder in a warming world - here’s why
4+ mon, 1+ week ago (822+ words) One of the strange things about climate change is that some parts of it are now understood very well, while others are still frustratingly hard to pin down. Scientists know the world is warming. They know warmer air can hold…...
