Cutting Greenhouse Gas Emissions Won't Slow Global Economic Growth — Report

          

Increased use of low-carbon energy sources instead of fossil energy sources is making it easier for countries to decouple economic growth from greenhouse gas emissions, according to a new report.  Photograph: Mick Tsikas/Reuters

New report from green think tank Heinrich Boll shows OECD countries grew their economies 16% in last decade – and cut greenhouse gas emissions 6.4%

As the world works out how to avoid catastrophic climate change, one of the biggest questions remaining is whether we can continue to grow economically without also increasing greenhouse gas emissions.

Why Some Scientists are Worried About a Surprisingly Cold ‘Blob’ in the North Atlantic Ocean

CLICK HERE - PAPER - Exceptional twentieth-century slowdown in Atlantic Ocean overturning circulation

washingtonpost.com - by Chris Mooney - September 24, 2015

. . . we learned from the National Oceanic and Atmospheric Administration that the first eight months of 2015 were the hottest such stretch yet recorded for the globe’s surface land and oceans, based on temperature records going back to 1880. . . .

In the North Atlantic Ocean south of Greenland and Iceland, the ocean surface has seen very cold temperatures for the past eight months. . . .

. . . And while there may not yet be any scientific consensus on the matter, at least some scientists suspect that the cooling seen in these maps is no fluke but, rather, part of a process that has been long feared by climate researchers — the slowing of Atlantic Ocean circulation.

India announces plan to slow rate of greenhouse gas growth

India has promised to shave a third off the rate at which it emits greenhouse gases over the next 15 years, in a long-awaited contribution towards reaching a deal to slow global warming at a U.N. climate summit in December.

The world's third-largest emitter and last major economy to submit plans ahead of the Paris summit did not, however, commit to any absolute cuts in carbon emissions.

Of the top two polluters, China has promised its emissions will peak by around 2030, and the United States is already cutting, but India says its economy is too small and its people too poor to agree to absolute cuts in greenhouse gases now.

Danger of Methane Explosions on Yamal Peninsula, Scientists Warn

      

Scientists from the respected Trofimuk Institute of Petroleum Geology and Geophysics insist the process by which a series of craters formed was caused by the melting of gas hydrates and the emission of methane. Picture: Vladimir Olenchenko/Trofimuk Institute of Petroleum Geology and Geophysics

More craters expected to form due to such eruptions as permafrost melts - and they ARE caused by global warming releasing methane gas.

siberiantimes.com - by Anna Liesowska - September 22, 2015

A new expedition to one of the mysterious Siberian giant holes found in recent years has concluded that it is a warning sign of a deadly threat to northern regions as the climate warms. . . .

. . . A pingo believed to be poised to explode 'at any moment' is now being constantly monitored by a Russian space satellite in an attempt to catch the moment when the eruption occurs. . . .

. . . The scientists also warn of a dire threat to both towns and cities in the extreme north, and natural gas exploration facilities and associated pipelines.

Syrian Civil War Prompts First Withdrawal From Doomsday Seed Vault In The Arctic

The Svalbard Global Seed Vault was opened on Feb. 26, 2008. Carved into the Arctic permafrost and filled with samples of the world's most important seeds, it's a Noah's Ark of food crops to be used in the event of a global catastrophe. AFP/Getty Images

A tall rectangular building juts out of a mountainside on a Norwegian island just 800 miles from the North Pole. Narrow and sharply edged, the facility cuts an intimidating figure against the barren Arctic background. But the gray building holds the key to the earth's biodiversity.

Ocean Fish Populations Cut In Half Since The 1970s: Report

CLICK HERE - Living Blue Planet Report 2015

Populations of some commercial fish stocks, such as a group including tuna, mackerel and bonito, had fallen by almost 75 percent.

huffingtonpost.com - by Andy Campbell - September 16, 2015

A disturbing new report published by the World Wildlife Fund found that the world marine vertebrate population declined by 49 percent between 1970 and 2012.

The Living Blue Planet Report -- analyzed by the Zoological Society of London and issued as an update on our oceans' health -- also found that local and commercial fish populations have been cut in half, tropical reefs have lost nearly half of their reef-building coral, and there are 250,000 metric tons of plastic in our oceans.

Worst-Case Scenario: If We Burn All Remaining Fossil Fuels, Antarctica Would Melt Entirely, Raise Sea Level 200 Feet

“Combustion of available fossil fuel resources sufficient to eliminate the Antarctic Ice Sheet.”

Few peer-reviewed study titles sound quite so much like a line spoken by the bad-news-bearing scientist from a dystopian sci-fi movie. But there it is. A real-world—and apparently very possible—dystopia.

Up in Maine, lobsters are thriving. The Atlantic States Marine Fisheries Commission reported last month that stocks there have reached a record high.

Down the coast, however, the story is different.

Grey Swan Hurricanes Pose Future Storm Surge Threat

Black swans are catastrophic events that no one sees coming, while “grey swans,” as the are known, are extreme events for which there’s no historical precedent, but that could still potentially be predicted. A new study takes this concept into the realm of weather and climate, finding that global warming might sharply increase the odds of grey swan hurricanes and storm surge over the coming century.

While such tempests would still remain relatively rare, they could pose unrecognized but potentially serious threats to coastal areas like Tampa, Fla., and Dubai, with storm surge totals reaching into the double digits when measured in feet.

Greenland's Jakobshavn Glacier Sheds Big Ice Chunk

         

This optical image of Jakobshavn glacier in western Greenland, acquired by Sentinel-2A on 16 August 2015, offers a valuable perspective of the scale of the calving event that took place between 14 and 16 August. The contour indicates the area of ice lost between images acquired on 6 and 16 August.

bbc.com - August 24, 2015

Scientists are studying a big mass of ice that has broken off the Jakobshavn Glacier in Greenland.

They say the 12.4km sq section is among the largest ever witnessed to come away from the ice stream's calving front.

Satellite imagery suggests the break-up occurred sometime between 13 and 19 August.
