Parched Earth soaks up water, slowing sea level rise

2016-02-12 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed

Agence France-Presse: As glaciers melt due to climate change, the increasingly hot and parched Earth is absorbing some of that water inland, slowing sea level rise, NASA experts said Thursday. Satellite measurements over the past decade show for the first time that the Earth's continents have soaked up and stored an extra 3.2 trillion tons of water in soils, lakes and underground aquifers, the experts said in a study in the journal Science. This has temporarily slowed the rate of sea level rise by about 20 percent,...

New Satellite Collects Sea Level Data to Monitor Climate Change

2016-01-31 16:23:00| Climate Ark Climate Change & Global Warming Newsfeed

Voice of America: Scientists from the U.S. and Europe have a new eye in the sky monitoring the world's oceans.The Jason-3 satellite, launched on January 17, is the latest satellite to monitor rising sea levels. Scientists say data collected by satellites over the last two decades shows sea levels rising at an accelerating rate, which they say is an indicator of climate change. Josh Willis, Lead Project Scientist for the Jason-3 mission at NASA's Jet Propulsion Laboratory said rising sea levels were one of the factors...

Sea level rise from ocean warming underestimated, scientists say

2016-01-26 03:19:00| Climate Ark Climate Change & Global Warming Newsfeed

Agence-France Presse: The amount of sea level rise that comes from the oceans warming and expanding has been underestimated, and could be about twice as much as previously calculated, German researchers have said. The findings in the Proceedings of the National Academy of Sciences, a peer-reviewed US journal, suggest that increasingly severe storm surges could be anticipated as a result. Sea level can mount due to two factors melting ice and the thermal expansion of water as it warms. Until now, researchers...

Greenland might be contributing more to sea level rise than we thought

2016-01-05 22:22:00| Climate Ark Climate Change & Global Warming Newsfeed

Grist: The Greenland ice sheet is starting to look a lot like the ice luge that ruined your New Year`s Eve. Except, instead of drunk faces at the end of it, there`s an ocean. And instead of cheap vodka flowing down its surface, there`s meltwater. It shouldn`t surprise you that Greenland is slowly melting away and will ultimately contribute to what could be catastrophic sea level rise (and if it does surprise you, then welcome to 2016 - you`re going to want to sit down for this). But until recently, the...

Climate change is altering Greenland ice sheet, accelerating sea level rise

2016-01-04 22:02:00| Climate Ark Climate Change & Global Warming Newsfeed

ScienceDaily: The Greenland ice sheet has traditionally been pictured as a bit of a sponge for glacier meltwater, but new research has found it is rapidly losing the ability to buffer its contribution to rising sea levels, says a York University researcher. York U Professor William Colgan, a co-author on the study published in the journal Nature Climate Change, helped analyse data from three expeditions to the Greenland ice sheet in 2012, 2013 and 2015. The research was done in conjunction with lead researcher...
