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

insidebayarea.com - by Seth Borenstein - January 18, 2016

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.

By 2050, There Will Be More Plastic than Fish in the World’s Oceans, Study Says

CLICK HERE - STUDY - Independent study tallies 'true catch' of global fishing

washingtonpost.com - by Sarah Kaplan - January 20, 2016

There is a lot of plastic in the world’s oceans.

It coagulates into great floating “garbage patches” that cover large swaths of the Pacific. It washes up on urban beaches and remote islands, tossed about in the waves and transported across incredible distances before arriving, unwanted, back on land. It has wound up in the stomachs of more than half the world’s sea turtles and nearly all of its marine birds, studies say . . .

. . . But that quantity pales in comparison with the amount that the World Economic Forum expects will be floating into the oceans by the middle of the century.

NASA Finds New Way to Track Ocean Currents from Space

NASA's GRACE satellites (artist's concept) measured Atlantic Ocean bottom pressure as an indicator of deep ocean current speed. In 2009, this pattern of above-average (blue) and below-average (red) seafloor pressure revealed a temporary slowing of the deep currents. Image credit: NASA/JPL-Caltech

jpl.nasa.gov - November 2nd, 2015

A team of NASA and university scientists has developed a new way to use satellite measurements to track changes in Atlantic Ocean currents, which are a driving force in global climate. The finding opens a path to better monitoring and understanding of how ocean circulation is changing and what the changes may mean for future climate.

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.

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.
