AAAS: "Oh, swell: Scientists identify a new way for your car to corrode," by Adrian Cho.

"Corrosion constantly destroys the integrity of metal objects ranging from bridges to cars, driving a global market for anti-corrosion coatings," which protect the metal from water, especially corrosive if it contains salt or acid. 

'Zhongyuan Ni + Hans-Jürgen Butt, interfacial physicists, now report that static electricity can breech such barriers. Polytetrafluoroethylene [PTFE]—commonly know as Teflon™—contains fluorine, carbon + hydrogen. "PTFE is inert to virtually all chemicals + considered the most slippery material in existence, making it one of the most valuable, versatile technologies invented." 

The physicists let droplets of slightly salty water fall from a syringe onto a copper surface coated with 60 nanometers [nm] of PTFE. Falling directly onto the surface, they rolled off harmlessly. But first running down a tilted insulating surface, the coated copper became pitted after a few thousand drops. 

"A trip down a few cm of window glass, a plastic building material, even a leaf from a potted plant was enough to make the droplets corrosive." Atomic force microscopy showed that some pits reached into the copper. "Fluorescence microscopy revealed that the copper exposed by the pits was reacting with the water." 

Electrodes revealed that neutral droplets gained up to 2 nanocoulombs before reaching the sample. When the droplets came within 10 micrometers of the surface, the tiny charge produced an electric field strong enough to cause PTFE to break down. "Engineers...may have missed the effect because they usually use coatings about 100 nm thick, too thick to be thus damaged." Coatings often include conductive layers, meant to prevent the buildup of static electricity + dust; those layers would short-circuit the corrosive effect.

Junwoo Park, a physical chemist at Sogang University, says “industry has effectively been operating in the safe zone without knowing it,” adding that the trend is to make coatings thinner. When coatings fail, experts typically blame pinholes, abrasion, or moisture ingress.

This new mechanism is death by a thousand cuts, as it were.

Earth has experienced major global warming events in the past. By studying molecular fossils preserved in rocks, scientists can reconstruct how climate, oxygen levels, and ecosystems changed during these periods. The evidence shows that Earth’s climate and ecosystems were eventually able to recover and rebalance, but this process could take a very long time. The key lesson is that while Earth has natural mechanisms for recovery, major climate changes can have long-lasting effects.

Will this country survive next decade because there are thousand of glacier up in the mountains of this country and that will only break,blast and cause flash flood in future.i might be wrong,what do you think.

President Donald Trump canceled the federal Solar for All program last August. EPA Administrator Lee Zeldin called the larger program it was a part of a ​“boondoggle.”

Indiana had been awarded a total of $117 million for solar, battery, and microgrid installations for marginalized communities under the program, which was created by the Inflation Reduction Act. Tens of millions of those dollars had been earmarked to pay for the Gary projects, which would have also brought 100 jobs to the once-thriving industrial city now notorious for disinvestment.

One of the community solar projects and about a dozen residential systems were planned for Gary, where poverty, crumbling infrastructure, unstable housing stock, and high rates of health problems exacerbate the damage and danger caused by power outages.

I’ve been listening to this podcast for awhile now but this one on the current state of our waterways has really got to me. If you genuinely want to understand what’s going on I highly suggest this podcast. It’s science based, factual and terrifying. It’s big big news that hasn’t yet made the mainstream news and I won’t be surprised if it ever does.

In 2016, the Silms River dried up, and the Kaskawalsh continued to retreat further. This rapid melting of glaciers is genuinely sad to see. And it brings a very real reality that if we continue to ignore climate change, drastic changes like this (the drying of the Silms River) will continue to happen. At only a faster rate.

What happened in Nepal this week is a brutal reminder of what climate injustice actually looks like.

A glacier collapse near the Nepal-Tibet border triggered a catastrophic flash flood. As of August 30, around 750 people have been reported dead and more than 3,000 are still missing. Entire communities, roads, bridges and power infrastructure have been swept away.

Scientists are still studying exactly how climate change contributed to this specific event, but there is a much bigger warning behind it: global warming is destabilising high-altitude environments, increasing the risks of glacier-related floods, landslides and other disasters in the Himalayas. Nepal has contributed almost nothing to the world's historical carbon emissions, yet it is facing consequences it had very little role in creating.

And Nepal isn't alone.

Pakistan has repeatedly faced devastating floods and extreme rainfall. Bangladesh faces cyclones, flooding and rising seas. Afghanistan faces drought and water stress. The Maldives faces sea-level rise. Across Africa, countries with tiny per-capita carbon footprints are dealing with floods, cyclones and droughts.

This is what climate injustice means.

And this is why the term “climate apartheid” is increasingly used.

By Global South, I don't simply mean China, or some abstract group of countries. I'm talking about millions of ordinary people in developing countries who are already struggling to afford basic necessities: food, housing, electricity, healthcare, education and clean water.

People who were already fighting an economic battle are now being forced to fight a climate battle they barely contributed to creating.

Someone in a wealthy country can often rebuild after a disaster, insure their home, move somewhere safer or afford air conditioning during extreme heat.

For millions in the Global South, there isn't even a safety net to begin with.

They didn't get the wealth created by centuries of carbon-intensive development.

But they're increasingly being asked to pay for its consequences.

The climate crisis is global.

The responsibility isn't equal.

And neither is the price.

In this episode we examine James Hansen’s analysis of a developing El Niño against the backdrop of a rapidly warming planet. We discuss Hansen’s warning that global warming may be accelerating as Earth absorbs more energy, and that an El Niño occurring on top of this elevated heat could help drive exceptionally high global temperatures in the years ahead.
