Mysteries of Martian ice cap solved
TEXAS-AUSTIN (US)—Scientists have reconstructed the formation of two curious features in the northern ice cap of Mars—a chasm larger than the Grand Canyon and a series of spiral troughs—solving a pair of mysteries dating back four decades—while also finding new evidence of climate change on Mars. (more…)

Carbon cycle snowballed out of control
PRINCETON (US)—New evidence uncovered by a team of geologists suggests that an episode 720 million years ago called “snowball Earth,” which may have covered the continents and oceans in a thick sheet of ice, produced a dramatic change in the carbon cycle. (more…)

Massive ice loss has sea levels rising
U. LEEDS (UK)—The loss of floating ice in the polar oceans each year—equivalent to 1.5 million Titanic-size icebergs—is causing sea levels to rise. (more…)

Little global warming goes a long way
PRINCETON (US)—The planet’s polar ice sheets are vulnerable to large-scale melting even under moderate global warming scenarios. Such melting would lead to a large and relatively rapid rise in global sea level, submerging many coastal areas. (more…)

Icy mile leads to climate future
The international North Greenland Eemian Ice Drilling, or NEEM, project begun in 2009 to retrieve deep ice cores from the Earth’s Eemian warm period 120,000 years ago. Atmospheric gases trapped in the ancient ice are expected to help scientists better assess the risks of abrupt climate change as Earth warms in the future. (Courtesy: NEEM Ice Core Drilling Project)
