A Shockingly Small Number of Earth's Population Still Have Access to Unpolluted Air

CLICK HERE - REPORT - State of Global Air 2018

sciencealert.com - by David Nield - April 19, 2018

How's the air in your neighbourhood today? A new State of Global Air report suggests more than 95 percent of the planet's population currently have to breathe polluted air – air containing fine particle levels that exceed the global air quality guidelines.

What's more, the burden of bad air quality is affecting the poorest communities the most. According to the US Health Effects Institute (HEI), which carried out the study, the gap between the most polluted and least polluted countries is steadily growing bigger.

This is having a real effect on health, too – an estimated 6.1 million deaths across the world in 2016 could be attributed to air pollution, the HEI reports. Strokes, heart attacks, lung cancer, and chronic lung disease were some of the health issues to blame.

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

CLICK HERE - STUDY - Evidence that the Great Pacific Garbage Patch is rapidly accumulating plastic

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.

Destruction of Nature as Dangerous as Climate Change, Scientists Warn

Unsustainable exploitation of the natural world threatens food and water security of billions of people, major UN-backed biodiversity study reveals

theguardian.com - by Jonathan Watts - March 23, 2018

Human destruction of nature is rapidly eroding the world’s capacity to provide food, water and security to billions of people, according to the most comprehensive biodiversity study in more than a decade.

Such is the rate of decline that the risks posed by biodiversity loss should be considered on the same scale as those of climate change, noted the authors of the UN-backed report, which was released in Medellin, Colombia on Friday.

Well, At Least One Catastrophic Climate Scenario Is Looking Less Likely

earther.com - by Maddie Stone - January 18, 2018

There’s been loads of media hype regarding the Arctic “methane bomb,” an idea that rising temperatures could cause a pulse of ancient methane, locked in permafrost and frozen hydrates on the ocean floor, to escape to the atmosphere, triggering catastrophic global warming. Well, we have some positive news for you: a new study finds little evidence to support this scenario playing out in at least one fast-warming part of the world . . .

 . . . “Our data suggest that even if increasing amounts of methane are released from degrading hydrates as climate change proceeds, catastrophic emission to the atmosphere is not an inherent outcome,” lead study author Katy Sparrow of the University of Rochester said in a statement.

Nation's largest oil refinery forced to shut down as Harvey floods Port Arthur

money.cnn.com - Julia Horowitz and Jill Disis - August 30th 2017

The largest oil refinery in the country is shutting down as Hurricane Harvey causes more catastrophic flooding, and more have followed suit.

Early Wednesday, Motiva said it started closing its Port Arthur refinery "in response to increasing local flood conditions." The plant won't open until flood waters recede.

Global fuel prices jump as Harvey's impact ripples beyond U.S. Gulf

reuters.com - Erwin Seba and Devika Krishna Kumar - August 31st 2017

Tropical Storm Harvey’s impact on the energy industry spread worldwide as flooded U.S. refiners and closed fuel pipelines threatened to squeeze national supply, roiling global fuel markets and rerouting millions of barrels of fuel to the Americas to avert shortages.

The storm, which lashed Louisiana with rain on Thursday, has pummeled the U.S. Gulf Coast, immersing Houston, Texas, and the surrounding area in several feet of water and forcing the closure of about a quarter of U.S. refining capacity.

Benchmark U.S. gasoline prices RBc1 and margins RBc1-Clc1 surged anew on Thursday.

Fukushima: Robot Images Show Massive Deposits Thought to be Melted Nuclear Fuel

Robot spots suspected debris of melted fuel for first time since 2011 earthquake and tsunami destroyed the plant

theguardian.com - Associated Press - July 22, 2017

Images captured by an underwater robot on Saturday showed massive deposits believed to be melted nuclear fuel covering the floor of a damaged reactor at Japan’s destroyed Fukushima nuclear plant.

The robot found large amounts of solidified lava-like rocks and lumps in layers as thick as 1m on the bottom inside a main structure called the pedestal that sits underneath the core inside the primary containment vessel of Fukushima’s Unit 3 reactor, said the plant’s operator, Tokyo Electric Power Co.

On Friday, the robot spotted suspected debris of melted fuel for the first time since the 2011 earthquake and tsunami caused multiple meltdowns and destroyed the plant.

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:

Carbon in Atmosphere Is Rising, Even as Emissions Stabilize

nytimes.com - by Justin Gillis - June 26, 2017

CAPE GRIM, Tasmania . . . For more than two years, the monitoring station here, along with its counterparts across the world, has been flashing a warning: The excess carbon dioxide scorching the planet rose at the highest rate on record in 2015 and 2016. A slightly slower but still unusual rate of increase has continued into 2017.

Scientists are concerned about the cause of the rapid rises because, in one of the most hopeful signs since the global climate crisis became widely understood in the 1980s, the amount of carbon dioxide that people are pumping into the air seems to have stabilized in recent years, at least judging from the data that countries compile on their own emissions.

That raises a conundrum: If the amount of the gas that people are putting out has stopped rising, how can the amount that stays in the air be going up faster than ever? Does it mean the natural sponges that have been absorbing carbon dioxide are now changing?
