New Map Reveals Giant Fjords Beneath East Antarctic Ice Sheet (VIDEO)
New Map Reveals Giant Fjords Beneath East Antarctic Ice Sheet (VIDEO)
Scientists from the United States, United Kingdom and Australia have used ice-penetrating radar to create the first high-resolution topographic map of one of the last uncharted regions of Earth, the Aurora Subglacial Basin, an immense ice-buried lowland larger than Texas in East Antarctica.
The map reveals some of the largest fjords or ice cut channels on Earth, providing important insights into the history of ice in Antarctica.

Big Clue to Future Climate Change in Small Plants
Big Clue to Future Climate Change in Small Plants
Yarrow, it's called, this flowering plant also known as "little feather" for the shape of its leaves. Prized as a garden plant that repels unwanted insects while attracting beneficial ones, it also improves soil quality and is used in many herbal medicines. Now yarrow--and 12 other grassland species, including Indian grass, thimbleweed and wild lupine--may have a larger role, scientists have found: as players in Earth's changing climate.
Clouds, a Weapon Against Climate Change?
Clouds, a Weapon Against Climate Change?
Some clouds cool the earth. But how are these clouds formed? How does the chemistry of the ocean affect their formation? Is this process affected by climate change? Can humans affect cloud formation to increase the cooling effect of clouds, having positive implications for the health of the planet?

Threading the Climate Needle: The Agulhas Current System
The Agulhas Current which runs along the east coast of Africa may not be as well known as its counterpart in the Atlantic, the Gulf Stream. But now researchers are taking a closer look at this current and its "leakage" from the Indian Ocean into the Atlantic Ocean--and what that may mean for climate change.
