Giant tortoises migrate unpredictably in the face of climate change Researchers use GPS to track the timing and patterns of giant tortoise migration over multiple years. The tortoises often take the same migration routes over many years in order to find optimal food quality and temperatures. The timing of this migration i

White people's eating habits produce most greenhouse gases White individuals disproportionately affect the environment through their eating habits by eating more foods that require more water and release more greenhouse gases through their production compared to foods black and Latinx individuals eat, according t
The solid Earth breathes The solid Earth breathes as volcanoes "exhale" gases like carbon dioxide (CO2) -- which are essential in regulating global climate -- while carbon ultimately from CO2 returns into the deep Earth when oceanic tectonic plates are forced to descend
Sometimes it's not good to be green The greening or eutrophication of the world's lakes will increase the emission of methane into the atmosphere by 30 to 90 percent during the next 100 years, say authors of a March 26, 2019 paper in Nature Communications. This increased methane emission is
When more women make decisions, the environment wins When more women are involved in group decisions about land management, the group conserves more - particularly when offered financial incentives to do so, according to a new University of Colorado Boulder study published this week in Nature Climate Change
Tropical storms likely to become more deadly as climate changes Tropical storms are likely to become more deadly under climate change, leaving people in developing countries, where there may be a lack of resources or poor infrastructure, at increased risk, new research from Oregon State University shows.
EPFL researchers make a key discovery on how alpine streams work An EPFL study has showed that until now, scientists have been substantially underestimating how quickly gases are exchanged between mountain streams and the atmosphere.
