Researchers Make Progress Toward High-Performing Water Desalination Membranes

http://www.sci-news.com/othersciences/materials/high-performing-water-desalination-membranes-09209.html

Biological membranes can achieve remarkably high permeabilities while maintaining ideal selectivities by relying on homogeneous internal structures in the form of membrane proteins. In new research, a team of scientists led by Penn State University and the University of Texas at Austin applied such design strategies to desalination polyamide membranes.

Dr. Enrique Gomez, Dr. Manish Kumar and their colleagues from Iowa State University, Penn State University, the University of Texas at Austin, DuPont Water Solutions, and Dow Chemical Co. found that creating a uniform membrane density down to the nanoscale of billionths of a meter is crucial for maximizing the performance of reverse-osmosis, water-filtration membranes.

Damage from whopper hurricanes rising for many reasons

 ...America and the world are getting more frequent and bigger multibillion dollar tropical catastrophes like Hurricane Laura, which is menacing the U.S. Gulf Coast, because of a combination of increased coastal development, natural climate cycles, reductions in air pollution and man-made climate change, experts say.

Study of Antarctic Sea Ice Collapse Warns of Potential 10-Foot Sea Rise

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.

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.

Higher Seas to Flood Dozens of US Cities, Study Says; Is Yours One of Them?

CLICK HERE - STUDY - Union of Concerned Scientists - When Rising Seas Hit Home: Hard Choices Ahead for Hundreds of US Coastal Communities (2017)

cnn.com - by Jennifer Gray - July 12, 2017

For the past several years, scientists have been trying to get people to wake up to the dangers that lie ahead in rising seas due to climate change. A comprehensive list now names hundreds of US cities, large and small, that may not make it through the next 20, 50 or 80 years due to sea level rise . . .

 . . . If you live along the coast, your city could be one of them -- meaning you could be part of the last generation to call it home.

"This research hones in on exactly how sea level rise is hitting us first. The number of people experiencing chronic floods will grow much more quickly than sea level itself," Benjamin Strauss, Vice President for Sea Level and Climate Impacts at Climate Central said in reaction to this study.

The Irish Pub near Atlantic City’s famed boardwalk doesn’t have any locks on the doors as it is open 24 hours a day. So when Hurricane Sandy crunched into what was once known as the Las Vegas of the east coast in 2012, some improvisation was needed.

Regular drinkers helped slot a cork board through the frame of the door, wedging it shut and keeping out the surging seawater.

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.

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

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.
