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.

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 . . .

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 . . .

Coastal cities around the world could be devastated by 1.3m of sea level rise this century unless coal-generated electricity is virtually eliminated by 2050, according to a new paper that combines the latest understanding of Antarctica’s contribution to sea level rise and the latest emissions projection scenarios.
