Communities in danger of falling into the sea say assistance from Washington has dried up: ‘It feels like a complete abdication of responsibility on climate change’

theguardian.com - by Oliver Milman - August 10, 2017

The US government’s withdrawal from dealing with, or even acknowledging, climate change may have provoked widespread opprobrium, but for Alaskan communities at risk of toppling into the sea, the risks are rather more personal.

The Trump administration has moved to dismantle climate adaptation programs including the Denali Commission, an Anchorage-based agency that is crafting a plan to safeguard or relocate dozens of towns at risk from rising sea levels, storms and the winnowing away of sea ice.

Federal assistance for these towns has been ponderous but could now grind to a halt, with even those working on the issue seemingly targeted by the administration.

Wildfires Hit Greenland After Record Temperatures

phys.org - August 14, 2017

Police in Greenland warned people to stay away from western areas of the island as wildfires scorched swathes of scrubland . . . 

 . . . Denmark's meteorological service BMI said the island registered its hottest-ever temperature of 24.8 degrees (77 Fahrenheit) on August 10.

Last year was Greenland's hottest on record.

The Danish territory has lost about 4,000 gigatons of ice since 1995, British researchers said in June, making ice melt on the huge island the biggest single contributor to rising sea levels.

Climate Report: Hottest Year, Highest Greenhouse Gas Marks, Record Sea Levels

cnn.com - by Steve Almasy - August 10, 2017

The records highlighted in the "State of the Climate in 2016" report from the National Oceanic and Atmospheric Administration sound ominous.

• Global land surface temperatures last year were highest in 137 years of record keeping.

• Sea surface temperatures were also at their highest.

• Sea levels were at record highs in the 24 years that satellite record keeping has been used.

• Greenhouse gas marks rose faster than any year and carbon dioxide readings were above a 400 parts per million average for the year for the first time.

Satellite Snafu Masked True Sea Level Rise for Decades

Revised tallies confirm that the rate of sea level rise is accelerating as Earth warms and ice sheets thaw

scientificamerican.com - by Jeff Tollefson - July 19, 2017

The numbers didn’t add up. Even as Earth grew warmer and glaciers and ice sheets thawed, decades of satellite data seemed to show that the rate of sea-level rise was holding steady—or even declining.

Now, after puzzling over this discrepancy for years, scientists have identified its source: a problem with the calibration of a sensor on the first of several satellites launched to measure the height of the sea surface using radar. Adjusting the data to remove that error suggests that sea levels are indeed rising at faster rates each year.

Rising Seas to Force Billions from Home

An estimated 2 billion people will be displaced from their homes by 2100 due to climate-driven rising seas, a new study says.

Roughly one-fifth of the world's population may become climate change refugees, according to Cornell University. The majority of those will be people who live on coastlines around the world, including about 2 million in Florida alone.

Scientists Just Documented a Massive Recent Melt Event on the Surface of Antarctica

washingtonpost.com - by Chris Mooney - June 15, 2017

Scientists have documented a recent, massive melt event on the surface of highly vulnerable West Antarctica that, they fear, could be a harbinger of future events as the planet continues to warm.

In the Antarctic summer of 2016, the surface of the Ross Ice Shelf, the largest floating ice platform on Earth, developed a sheet of meltwater that lasted for as long as 15 days in some places. The total area affected by melt was 300,000 square miles, or larger than the state of Texas, the scientists report.

That’s bad news because surface meltin g could work hand in hand with an already documented trend of ocean-driven melting to compromise West Antarctica, which contains over 10 feet of potential sea level rise.

Scientists Say the Pace of Sea Level Rise Has Nearly Tripled Since 1990

A new scientific analysis finds that the Earth’s oceans are rising nearly three times as rapidly as they were throughout most of the 20th century, one of the strongest indications yet that a much feared trend of not just sea level rise, but its acceleration, is now underway.

“We have a much stronger acceleration in sea level rise than formerly thought,” said Sönke Dangendorf, a researcher with the University of Siegen in Germany who led the study along with scientists at institutions in Spain, France, Norway and the Netherlands.

Rift in Antarctica's Larsen C Ice Shelf

submitted by Albert Gomez

           

On Nov. 10, 2016, scientists on NASA's IceBridge mission photographed an oblique view of a massive rift in the Antarctic Peninsula's Larsen C ice shelf. Icebridge, an airborne survey of polar ice, completed an eighth consecutive Antarctic deployment on Nov. 18.

nasa.gov - December 1, 2016 - Editor: Sarah Loff

Ice shelves are the floating parts of ice streams and glaciers, and they buttress the grounded ice behind them; when ice shelves collapse, the ice behind accelerates toward the ocean, where it then adds to sea level rise. Larsen C neighbors a smaller ice shelf that disintegrated in 2002 after developing a rift similar to the one now growing in Larsen C.

The IceBridge scientists measured the Larsen C fracture to be about 70 miles long, more than 300 feet wide and about a third of a mile deep. The crack completely cuts through the ice shelf but it does not go all the way across it – once it does, it will produce an iceberg roughly the size of the state of Delaware.

Unless the world stops burning fossil fuels that are fuelling global warming, irreversible changes in the Arctic could have disastrous effects for the people that live there and for the rest of the planet, researchers warned on Friday.

The Arctic's ecosystems are fundamentally threatened by climate change and other human activities, such as oil and gas extraction, they said in a report for the Arctic Council, an inter-governmental forum working to protect the region's environment.
