Tsunami shears off icebergs in Antarctica
U. CHICAGO (US) — Scientists have observed for the first time the power of a tsunami to break off large icebergs—in this case, the chunks of ice together equaled about two times the surface area of Manhattan. (more…)

Glacier’s size runs hot and cold
U. BUFFALO (US) — Calving glaciers are particularly sensitive to climate change, shrinking rapidly in response to global warming and growing at a similar pace during periods of cooling. (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…)

Greenland melt spreads to both coasts
U. COLORADO (US)—Ice loss from the Greenland ice sheet, which has been increasing during the past decade over its southern region, is now making an upward climb on its northwest coast as well. (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…)
