Coral warns of rising seas
The most alarming aspect of the research is that scientists have no way of predicting when ice sheets will collapse, causing a surge in sea levels. “The problem with melting ice sheets is that it doesn’t happen gradually or steadily. It can be catastrophic and … the concern is the rate of sea level rise,” said McCulloch. “There may not be much time. These things could happen quite rapidly, like tens of years.”

Scores of icebergs have floated to within about 300 km (186 miles) of New Zealand, with the largest measuring about 1.8 km (1.1 miles) in length and standing some 120 metres (360 feet) above water.(Xinhua/Reuters Photo)

Pointing at icebergs as evidence of global warming is Chicken Little like.
ReplyDeleteIce sheets thousands of years old collapse evry summer in the arctic and antarctic.A hundred years ago the Titanic ran into one farther south than expected and sank.
Some icebergs are reported up to 2,500 kilometeres long.
