Cleaner cookstoves could save millions of lives and slow global warming.
Arctic Pioneers
Like the pioneers of the American West, the birds that are now settling the Arctic frontier in response to climate change aren’t necessarily the biggest or the strongest, but may instead be castoffs from more hospitable settled areas.
Mountain Legacy Project
Scientists are using the science of computer vision to document climate change in the Rocky Mountains.
Ocean Quadcopter
A tiny but rugged unmanned helicopter helps researchers collect data in the stormy North Atlantic.
Changing Foliage
Climate change may affect fall foliage in many different ways.
Insect Weather Prediction
Insects may be able to “predict” the weather by changing their behavior when they sense changes in air pressure.
