In some species of reptiles, gender is determined not by X and Y chromosomes, but rather by the temperature in the nest at a key period of development. So, as temperature warm, for the Painted turtles, that means a species that will become all female. And when that happens, the species will die out.
This year has seen many more landslides in the Pacific Northwest than is typical -- in fact this recent winter was among the worst for mudslides in and around the Puget Sound region. Experts say this could be more common as climate change leads to more rain, especially in the Pacific Northwest.
A warming climate is likely to mean rising rainfall totals in part of the world -- which could lead to flooding. But scientists in the United Kingdom are hoping to ameliorate that somewhat, by producing a new kind of grass that helps the soil absorb more water.
The U.S. State Department has prepared an Environmental Impact Statement for the pending, and controversial, Keystone XL pipeline that lays the groundwork for the project to go ahead. The Environmental Protection Agency, however, has some issues with what the statement says.
Kenya's Maasai people have a distinct culture — distinct clothes and and habits that make them stand out among people. But that historic way of life is threatened by climate change, making their traditional lifestyle increasingly untenable.
Students across the United States and Canada were challenged to come up with ways to improve their local environment. If the ideas were good enough, they could win a tip to Costa Rica for a youth leaders summit on the environment.
A New York zoo is hand-rearing a polar bear cub born to one of its adult bears. But now, the zoo is being asked to take in another cub, an orphan, from Alaska, in hopes that the two will grow up healthier if they do so together.
Carbon compounds found in a drill sample from Mars and microbes found below the Earth's surface could be related to one another according to researchers at the Deep Carbon Observatory. Though they're learning more about deep microbial life, some researchers say it could be the link to previous life on Mars.
Lakes high in the world's mountains are becoming increasingly dangerous to the towns that have sprouted up near them. The lakes are prone to floods, typically caused when the mountain glaciers that feed them shed a chunk of ice and rock, forcing thousands of gallons over the banks.
The rapidly melting sea ice in the Arctic is threatening the livelihood of polar bears and their prey. In response, a group of researchers is suggesting a program of supplemental feeding as a potential solution.
