As glacial cliffs break off and destabilize frozen landscapes, glaciologist Richard Alley focuses on the fractures. The work could improve predictions about future sea-level rise.
As wind power grows around the world, so does the threat the turbines pose to wildlife. From simple fixes to high-tech solutions, new approaches can help.
Evidence that the approach helps to save trees, preserve ecosystems and reduce carbon emissions is often hard to come by. But it can succeed if it’s done right, says an economist.
OPINION: The notion of planting miles of trees to hold back encroaching deserts is misguided and damaging; we should promote programs that secure livelihoods and respect dryland ecologies instead
OPINION: Zero-deforestation supply-chain commitments aren’t protecting tropical forests as much as hoped. But they might, if the same standards were applied to domestic and export markets.
The wet landmasses, though inherently impermanent, have been essential to both people and wildlife for thousands of years. But recent shifts have brought on some rapid losses that worry scientists.
OPINION: Ocean warming, acidification and deoxygenation due to climate change — as well as pollution and development — threaten our global waters, but disaster is far from inevitable
Rich data on the global state of our feathered friends presents plenty of bad news — but also some bright spots. Researchers know better than ever how to help endangered birds, and there are notable bird conservation successes.
PODCAST: A report to the US president sounded an alarm — humankind was ‘conducting a vast geophysical experiment’ by burning fossil fuels and filling the atmosphere with an ‘invisible pollutant.’ But a slick campaign by Big Oil led to confusion, politicization and dire consequences for the planet. (Season 3, Episode 1)
Bt crops keep many agricultural pests at bay and have drastically reduced the use of pesticides. But scientists warn that these valuable tools are in jeopardy due to overuse and abuse.
Lawsuits against emissions-spewing governments and fossil fuel companies have established themselves as a key tool in the battle against climate change, but they aren’t always successful
Our bodies crave more food if we haven’t had enough protein, and this can lead to a vicious cycle — especially if we’re reaching for ultraprocessed instead of high-fiber whole foods
