How plastic-industry pollution threatens Gulf seafood [Opinion] - HoustonChronicle.com

From Padre Island to the Florida Keys, the Gulf of Mexico is turning into a plastic soup. Researchers are finding microplastic trash in almost every water sample collected from the Gulf, at some of the highest concentrations reported in the world. And the situation is about to get far worse — off the Texas coast and in other U.S. waterways.

That’s because the petro-plastic industry is embarking on a reckless expansion boom. Determined to turn the country’s oversupply of fracked natural gas into more throwaway packaging and products, industry plans to build or expand 80 facilities that turn fracked gas into plastic, including 48 in Texas.

World Hunger Is on the Rise - Heated

Let’s face it: The U.S. is not feeding the world

For the third straight year, U.N. agencies have documented rising levels of severe hunger in the world, affecting 820 million people. More than 2 billion suffer “moderate or severe” food insecurity. During the same period, the world is experiencing what Reuters called a “global grains glut,” with surplus agricultural commodities piled up outside grain silos rotting for want of buyers.

Obviously, growing more grain is not reducing global hunger.

Yet every day, some academic, industry, or political leader joins the Malthusian chorus of warnings about looming food shortages due to rising populations and strained natural resources. For example, here’s Richard Linton, dean of the College of Agriculture and Life Sciences at North Carolina State University, sounding the familiar alarm: “We’ve got to find a way to feed the world, double the food supply,” he said. “And we all know if we don’t produce enough food, what the outcome is: it’s war, it’s competition.”

“How will we feed the world?” calls the preacher. “Increase our bounty,” responds the choir.
There is so much wrong with that answer. And even with the question, which is profoundly arrogant.

How will “we” feed “the world?” We know who we mean when we ask that question: rich countries, with high-yield seeds and industrial-scale agriculture. The United States thinks it’s feeding the world now. It is not.

Climate change: Arctic permafrost now melting at levels not expected until 2090 | The Independent

My comment: One of the tipping points I posted about earlier. Things are speeding up. 10-15 years may be too optimistic?

Series of 'anomalously warm summers' caused ground to thaw, researchers say

Permafrost hs begun thawing in the Canadian Arctic more than 70 years early because of climate change, according to new research.

A "series of anomalously warm summers” has dramatically accelerated melting rates at three sites despite average annual ground temperatures remaining low. Ponds and hillocks have formed as a result. 

It had been thought that the permafrost - ground that remains frozen for at least two years - would remain until at least 2090.

But the study found thawing levels were above 150 to 240 per cent above historic levels. 

Researchers called this a “truly remarkable amount".

Image result for permafrost thawing early

Mould Bay on Prince Patrick Island was the worst-affected site, according to the study, published on the journal Geophysical Research Letters

There, permafrost thawing levels were 240 per cent higher than historic levels and the ground sank 90cm over the course of the study which ran for over 12 years, between 2003 and 2016.

Researchers also recorded thawing at depths not expected until air temperatures rose to levels that the UN Intergovernmental Panel on Climate Change (IPCC) predicted it would reach in 2090...

It’s the End of the World as They Know It – Mother Jones

The distinct burden of being a climate scientist

STORY BY DAVID CORN; PHOTOS BY DEVIN YALKINJULY 8, 2019



On election night 2016, Kim Cobb, a professor at the School of Earth and Atmospheric Sciences at Georgia Tech, was on Christmas Island, the world’s largest ring-shaped coral reef atoll, about 1,300 miles south of Hawaii. A climate scientist, she was collecting coral skeletons to produce estimates of past ocean temperatures. She had been taking these sorts of research trips for two decades, and over recent years she had witnessed about 85 percent of the island’s reef system perish due to rising ocean temperatures. “I was diving with tears in my eyes,” she recalls.



In a row house made of cinder blocks on the tiny island in the middle of the Pacific Ocean, she monitored the American election results, using a satellite uplink that took several minutes to load a page. When she saw Donald Trump’s victory, she felt shock and soon descended into severe depression. “I had the firm belief that Washington would act on climate change and would be acting soon,” the 44-year-old Cobb says. “When Trump was elected, it came crashing down.”

PFAS Resources — The Endocrine Disruption Exchange

PFAS (per- and poly- fluorinated alkyl substances) comprise a group of over 5,000 chemicals, many of which are toxic to humans and wildlife and last so long in the environment they have been referred to as ‘forever chemicals’. PFAS are used in numerous consumer products to confer waterproof, greaseproof, stain-proof and non-stick properties. They are also used for industrial purposes such as fire fighting foam. It is now becoming clear that PFAS are in the food, water, air, and bodies of many people around the world. The few PFAS that have been thoroughly studied show adverse impacts on the endocrine, immune, and metabolic systems.

The Cure to the Tragedy of the Commons? Cooperation | Hakai Magazine

When fishers communicate openly, coral reefs win.



Fishers who keep their lines of communication open — even when they are competing for the same fish — end up with healthier fishing grounds. Researchers interviewed almost 650 fishers in Kenya and found that those who shared info about when and how they work had more fish and higher biodiversity in their waters. “The hardest thing in conservation is getting a bunch of disparate people to cooperate to ensure the perpetuation of a resource that they all depend on,” says ecologist Jack Kittinger. “When that happens, lo and behold, you’ve got better ecological success.”

July on course to be hottest month ever, say climate scientists | Environment | The Guardian

If global trends continue for another fortnight, it will beat previous two-year-old record

Record temperatures across much of the world over the past two weeks could make July the hottest month ever measured on Earth, according to climate scientists.
The past fortnight has seen freak heat in the Canadian Arctic, crippling droughts in Chennai and Harare and forest fires that forced thousands of holidaymakers to abandon campsites in southern France and prompted the air force in Indonesia to fly cloud-busting missions in the hope of inducing rain.
If the trends of the first half of this month continue, it will beat the previous record from July 2017 by about 0.025C, according to calculations by Karsten Haustein, a climate scientist at the University of Oxford, and others.

This follows the warmest-ever June, which was confirmed this week by data from the US space agency Nasa, following Europe’s Copernicus satellite monitoring system.
