Scientists look at past climates to learn about climate change and the ability to simulate it with computer models. One region in particular that has received a great deal of attention is the Indo-Pacific warm pool, the vast pool of warm water stretching along the equator from Africa to the western Pacific Ocean.
While sea level rises caused by global warming threaten islands, a tiny marine creature appears to be riding to the rescue, spreading rapidly through the oceans and stabilizing coastlines.
Sea levels are rising much faster than the Intergovernmental Panel on Climate Change's (IPCC) projections predict - 60 percent faster, in fact.
Whatever we do, greenhouse gas emissions have alreadytriggered an irreversible warming of Earth that will cause sea levels to rise for more than a thousand years to come, claims a European team.
Sea level rises are accelerating along parts of the US East Coast as much as four times faster than the average for the rest of the world.
While Greenland's glaciers are moving ever-faster twowards the sea, they're not accelerating as much as believed, indicating that future sea level rises could be a lot less than current worst-case scenarios.
The loss of Antarctic ice is caused mainly by warm ocean currents attacking the underside of ice shelves, a new NASA study has revealed.
Scientists studying coral off the coast of Tahiti have linked a collapse of the world's ice sheets 14,600 years ago to a sudden 14-meter rise in global sea-levels.
While glaciers globally are shedding billions of tons of ice each year, the Himalayas aren't, a study shows.
New research from NASA into the Earth's paleoclimate history indicates we could be facing rapid climate change this century, including sea level rises of many meters.
A NASA-funded team of scientists is to drill into a rapidly-thinning Antarctic glacier to try and establish the effect its melting will have on sea levels.
Melting mountain glaciers are pushing up sea level rises faster than at any time in the last 350 years, say scientists - indeed, many are melting up to 100 times faster.
Last year's melting of the Greenland Ice Sheet was the worst ever recorded, according to research from the City College of New York.
Tackling sea level rises though geoengineering won't work, and would impose enormous risks on future generations, according to an international research team.
