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.

The oceans are warming faster than previously estimated, setting a new temperature record in 2018 in a trend that is damaging marine life, scientists said on Thursday.

New measurements, aided by an international network of 3,900 floats deployed in the oceans since 2000, showed more warming since 1971 than calculated by the latest U.N. assessment of climate change in 2013, they said.

And “observational records of ocean heat content show that ocean warming is accelerating,” the authors in China and the United States wrote in the journal Science of ocean waters down to 2,000 metres (6,600 ft).

Seabed Mining Can Decide the Fate of the Deep Ocean

At the International Seabed Authority’s ocean-side headquarters, delegates from dozens of countries strolled through breezeways adorned with the works of Jamaican artists as the United Nations-chartered organization’s annual meeting began its second week. No one, however, was entering a conference room where the seabed authority’s Legal and Technical Commission (LTC) was in session and men in dark suits stood watch. A sign advised that the meeting was "closed."

Behind heavy wood doors, the 30 members of the commission convened in secret to discuss, among other things, confidential contracts issued to corporations and state-backed companies to explore and potentially mine vast, barely explored deep-sea habitats that scientists believe play a key role in the global ecosystem.

Pacific Plastic Dump Far Larger Than Feared: Study

           

Eight million tonnes of plastics enter the oceans every year, much of which has accumulated in five giant garbage patches around the planet, according to a new study.  CAROLINE POWER PHOTOGRAPHY/AFP/File / Handout

phys.com - by Patrick Galey And Marlowe Hood - March 22, 2018

The vast dump of plastic waste swirling in the Pacific ocean is now bigger than France, Germany and Spain combined -- far larger than previously feared -- and is growing rapidly, a study published Thursday warned.

Researchers based in the Netherlands used a fleet of boats and aircraft to scan the immense accumulation of bottles, containers, fishing nets and microparticles known as the "Great Pacific Garbage Patch" (GPGP) and found an astonishing build-up of plastic waste.

"We found about 80,000 tonnes of buoyant plastic currently in the GPGP," Laurent Lebreton, lead author of the study published in the journal Scientific Reports, told AFP.

Ocean Acidification Poses Threat to Sea Life, Research Finds

news.sky.com - by Rebecca Taylor - October 23, 2017

Increased acidity in the oceans could affect many species including molluscs and corals, an eight-year study has found.

The research from more than 250 scientists also highlighted the risk of knock-on effect up the food chain.

Increased acidity in the oceans, called by some the "evil twin of global warming", compounds the effect of rising temperatures.

TEPCO Chair: Nuclear Plant Must Release Contaminated Water

           

Tokyo Electric Power Co.'s new Chairman Takashi Kawamura speaks during an interview at the TEPCO headquarters in Tokyo on Thursday, July 13, 2017. Kawamura said the utility needs to stop dragging its feet on plans to dump massive amounts of treated but contaminated water into the sea and make more money if it’s ever going to succeed in cleaning up the mess left by meltdowns more than six years ago at the tsunami-hit Fukushima nuclear power plant.

. . . Takashi Kawamura, an engineer-turned-business leader who previously headed Hitachi's transformation into a global conglomerate, is in charge of reviving TEPCO and leading the cleanup at the Fukushima Dai-Ichi plant. In an interview Thursday with selected media including The Associated Press, Kawamura said despite the massive costs of the cleanup and meeting tighter safety requirements, nuclear power is still vital for Japan's national security.

Below are highlights from the interview, where Kawamura spoke in Japanese:

27,000 Abandoned Oil and Gas Wells in Gulf of Mexico Ignored by Government, Industry

An older nearshore wellhead is shown off the coast of California in this undated photo. In state waters, California has resealed scores of its abandoned wells since the 1980s, but in federal waters, the official policy is out-of-sight, out-of-mind. Neither industry nor government checks for leaks at the more than 27,000 oil and gas wells abandoned in the Gulf of Mexico since the late 1940s. Abandoned wells are known sometimes to fail both on land and offshore. It happens so often that a technical term has been coined for the repair job: "re-abandonment."  Photo: California State Lands Commission / The Associated Press

nola.com - Associated Press - July 7, 2010

More than 27,000 abandoned oil and gas wells lurk in the hard rock beneath the Gulf of Mexico, an environmental minefield that has been ignored for decades. No one -- not industry, not government -- is checking to see if they are leaking, an Associated Press investigation shows.

The oldest of these wells were abandoned in the late 1940s, raising the prospect that many deteriorating sealing jobs are already failing.

The terrifying tsunami that devastated Britain

bbc.com - March 29th 2016 - Amanda Ruggeri

It was an autumn day in the Shetland Islands of Scotland. Perhaps fishing boats were hauling in catch; maybe children were playing on the beach. Then it came in: a wall of water reaching a height of 25m above normal sea level at some points, high enough to top a seven-storey building.

Australia's Great Barrier Reef hit by 'worst' bleaching

The Great Barrier Reef is the world's largest living structure and can be seen from space.

bbc.com - March 29th 2016

Evidence that Australia's Great Barrier Reef is experiencing its worst coral bleaching on record has renewed calls for the UN to list it as "in-danger".

The National Coral Bleaching Taskforce says 95% of reefs from Cairns to Papua New Guinea are now severely bleached.

It says only four reefs out of 520 have no evidence of bleaching.

Study: Oceans Trapping Heat at Accelerating Rate

CLICK HERE - STUDY - Nature Climate Change - Industrial-era global ocean heat uptake doubles in recent decades

WASHINGTON -- The amount of man-made heat energy absorbed by the seas has doubled since 1997, a study released Monday showed.

Scientists have long known that more than 90 percent of the heat energy from man-made global warming goes into the world's oceans instead of the ground.

And they've seen ocean heat content rise in recent years. But the new study, using ocean-observing data that goes back to the British research ship Challenger in the 1870s and including high-tech modern underwater monitors and computer models, tracked how much man-made heat has been buried in the oceans in the past 150 years.
