Climate change is eliminating giant chunks of ice from Greenland at such a speed that the melt has already made a significant contribution to sea level rise, according to a new study. With global warming, the island will lose much more, threatening coastal cities around the world.

Forty percent to 50% of the planet's population is in cities that are vulnerable to sea rise, and the study published Monday in the Proceedings of the National Academy of Sciences is bad news for places like New York, Miami, Los Angeles, Tokyo and Mumbai.

Study of Antarctic Sea Ice Collapse Warns of Potential 10-Foot Sea Rise

The faster the ocean warms, the faster key Antarctic glaciers will disintegrate.

A stunning new study on Antarctic sea ice collapse greatly raises the risk of a 10-foot sea level rise this century if President Donald Trump’s climate policies aren’t quickly reversed.

Warming ocean waters drove a 6-fold increase in annual ice mass loss from the Antarctic ice sheet between 1979 and 2017, according to a new study in the Proceedings of the National Academy of Sciences.

It’s been known for a while that the West Antarctic Ice Sheet (WAIS) was unstable and collapsing at an accelerating rate due to global warming. But the new study finds that parts of the vastly larger East Antarctic Ice Sheet (EAIS) are also disintegrating.

Kiribati: a Drowning Paradise in the South Pacific

DW Documentary - November 8, 2017

Climate change and rising sea levels mean the island nation of Kiribati in the South Pacific is at risk of disappearing into the sea.

But the island’s inhabitants aren’t giving up. They are doing what they can to save their island from inundation.

As the UN sits down for its annual climate conference this week, many experts believe we have passed the point of no return

theguardian.com - by Robin McKie - December 2, 2018

On Sunday morning hundreds of politicians, government officials and scientists will gather in the grandeur of the International Congress Centre in Katowice, Poland . . . For 24 years the annual UN climate conference has served up a reliable diet of rhetoric, backroom talks and dramatic last-minute deals aimed at halting global warming . . .

. . . As recent reports have made clear, the world may no longer be hovering at the edge of destruction but has probably staggered beyond a crucial point of no return. Climate catastrophe is now looking inevitable.

A Radical New Scheme to Prevent Catastrophic Sea-Level Rise

           

A Princeton glaciologist says a set of mega-engineering projects may be able to stabilize the world’s most dangerous glaciers.

 . . . What if scientists could prevent one catastrophic symptom of climate change—a rapid rise in global sea level, for instance—without messing again with the weather?

Michael Wolovick, a glaciology postdoc at Princeton University, believes it may be possible.

For the past two years, Wolovick has studied whether a set of targeted geo-engineering projects could hold off the worst sea-level rise for centuries, giving people time to adapt to climate change and possibly reverse it.

West Antarctic Ice Melt Poses Unique Threat to U.S.

axios.com - by Andrew Freedman - June 14, 2018

News of Antarctica's accelerating ice melt garnered worldwide headlines yesterday, as scientists revealed that 3 trillion tons of ice has been lost to the sea since 1992 — mostly from the thawing West Antarctic Ice Sheet and Antarctic Peninsula.

Why it matters: The location of the ice melt is important for determining the future of coastal communities, according to climate scientists. And, due to West Antarctica melting, it turns out that the U.S. coastline will be hit extra hard . . .

Antarctica’s ice sheet is melting at a rapidly increasing rate, now pouring more than 200 billion tons of ice into the ocean annually and raising sea levels a half-millimeter every year, a team of 80 scientists reported Wednesday.

Seas to Rise About a Meter Even if Climate Goals Are Met - Study

Sea levels will rise between 0.7 and 1.2 meters (27-47 inches) in the next two centuries even if governments end the fossil fuel era as promised under the Paris climate agreement, scientists said on Tuesday.

Early action to cut greenhouse gas emissions would limit the long-term rise, driven by a thaw of ice from Greenland to Antarctica that will re-draw global coastlines, a German-led team wrote in the journal Nature Communications . . .

 . . . By 2300, the report projected that sea levels would gain by 0.7-1.2 meters, even if almost 200 nations fully meet goals under the 2015 Paris Agreement, which include cutting greenhouse gas emissions to net zero in the second half of this century . . .

Satellite Observations Show Sea Levels Rising, and Climate Change Is Accelerating It

Sea level rise is happening now, and the rate at which it is rising is increasing every year, according to a study released Monday in the Proceedings of the National Academy of Sciences.

Researchers, led by University of Colorado-Boulder professor of aerospace engineering sciences Steve Nerem, used satellite data dating to 1993 to observe the levels of the world's oceans.

Using satellite data rather than tide-gauge data that is normally used to measure sea levels allows for more precise estimates of global sea level, since it provides measurements of the open ocean.
