Scientists have been experimenting with "fog harps" in arid climates as an easy way to collect potable water from fog.
Via the paper:
Fog harvesting is a useful technique for obtaining fresh water in arid climates. The wire meshes currently utilized for fog harvesting suffer from dual constraints: coarse meshes cannot efficiently capture microscopic fog droplets, whereas fine meshes suffer from clogging issues. Here, we design and fabricate fog harvesters comprising an array of vertical wires, which we call “fog harps”. Under controlled laboratory conditions, the fog-harvesting rates for fog harps with three different wire diameters were compared to conventional meshes of equivalent dimensions. As expected for the mesh structures, the mid-sized wires exhibited the largest fog collection rate, with a drop-off in performance for the fine or coarse meshes. In contrast, the fog-harvesting rate continually increased with decreasing wire diameter for the fog harps due to efficient droplet shedding that prevented clogging. This resulted in a 3-fold enhancement in the fog-harvesting rate for the harp design compared to an equivalent mesh.
Storm Emma, a massive weather system that brought bitter cold and snow to the U.K. this past week did a lot of damage to power grids, forced the closure of schools and caused havoc for anyone looking to travel anywhere in Scotland, England, Wales and Northern Ireland (the Republic of Ireland took its share of knocks, too.) Perhaps worst of all, was the destructive effect the drastic drop in temperature had on sea life in the water surrounding the United Kingdom. This YouTube video shot at Ramsgate Beach in Kent, illustrates what a change in temperature can do to a delicate species of animal--if this isn't a prime example of why climate change is such an important issue, I don't know what is.

In Potentially dangerous consequences for biodiversity of solar geoengineering implementation and termination (published in Nature Ecology and Evolution, Sci-Hub mirror), a group of cross-institutional US climate scientists model what would happen if human embarked upon a solar geoengineering project to mitigate the greenhouse effect by aerosolizing reflective particles into the atmosphere, then gave up on the project after a mere half-century.

Written by Tennessee Mowrey and Kevin Goldberg, the song is a wake-up call to Trump and any other "fucking asshole" who doesn't believe that climate change exists.
It was co-produced by my pal Ampersand, who writes:
"I immediately felt that these spirited and pissed off millennials were giving voice not only to my feelings about our president and his policies around climate change, but potentially to millions of others as well, and that it was important that the song was out in the world."
Give it a watch. Be forewarned, it's (rightly) sprinkled with NSFW language.
NYMag's David Wallace-Wells breaks it to us ungently: the Paris Climate Accord, torn up by Trump, was already a compromise that likely condemned much of the equatorial belt to crippling heatwaves. Without it, climate change will only be worse.

Even if we meet the Paris goals of two degrees warming, cities like Karachi and Kolkata will become close to uninhabitable, annually encountering deadly heat waves like those that crippled them in 2015. At four degrees, the deadly European heat wave of 2003, which killed as many as 2,000 people a day, will be a normal summer. At six, according to an assessment focused only on effects within the U.S. from the National Oceanic and Atmospheric Administration, summer labor of any kind would become impossible in the lower Mississippi Valley, and everybody in the country east of the Rockies would be under more heat stress than anyone, anywhere, in the world today. As Joseph Romm has put it in his authoritative primer Climate Change: What Everyone Needs to Know, heat stress in New York City would exceed that of present-day Bahrain, one of the planet’s hottest spots, and the temperature in Bahrain “would induce hyperthermia in even sleeping humans.” The high-end IPCC estimate, remember, is two degrees warmer still.
Bruce Sterling's short story "The Beachcomber of Novi Kotor" is a monologue by a rogue Montenegran artist-roboticist, delivered at the 85th Venice Biennale, in a world where climate change has made venices out of all the world's low-lying cities, where Montenegro has been plunged into economic collapse by the precipitous departure of the neo-Czarist Russian oligarchs whose tourist trade it depended on.

Hurricane season officially began yesterday, but let's hope now more than ever that one doesn't hit the US anytime soon. Because guess what? No one is in charge of the National Oceanic and Atmospheric Administration (NOAA), the agency that predicts and forecasts hurricanes ahead of a storm. And for an extra thrill, no one is in charge of the Federal Emergency Management Agency (FEMA) either, the agency that responds to disasters and offers relief. Read the rest
Emmanuel Macron, the President of France, rewrote U.S. President Donald Trump's 'MAGA' campaign slogan today in protest of the administration's absurd withdrawal from the Paris climate accords. "Make Our Planet Great Again," says Macron. We're in alignment with Nicaragua and Syria, says Trump. Read the rest
Strategically placed to survive any natural disaster, this winter's rains flooded the arctic seed bank. The bank wasn't destroyed, but it shows how fast things are a changing.

It was designed as an impregnable deep-freeze to protect the world’s most precious seeds from any global disaster and ensure humanity’s food supply forever. But the Global Seed Vault, buried in a mountain deep inside the Arctic circle, has been breached after global warming produced extraordinary temperatures over the winter, sending meltwater gushing into the entrance tunnel.
The vault is on the Norwegian island of Spitsbergen and contains almost a million packets of seeds, each a variety of an important food crop. When it was opened in 2008, the deep permafrost through which the vault was sunk was expected to provide “failsafe” protection against “the challenge of natural or man-made disasters”.
But soaring temperatures in the Arctic at the end of the world’s hottest ever recorded year led to melting and heavy rain, when light snow should have been falling. “It was not in our plans to think that the permafrost would not be there and that it would experience extreme weather like that,” said Hege Njaa Aschim, from the Norwegian government, which owns the vault.
The Alabama Center for Rural Enterprise worked with Houston's National School of Tropical Medicine to sample "soil and water...blood and faecal samples" from Alabama's Lowndes County, a poor rural area. Read the rest
When inventor and MacArthur "genius grant" recipient Saul Griffith started reading papers about global warning that were written in 1974 (the same year he was born) he discovered that "all the problems we face today are familiar from 43 years ago. All the proposed solutions are similar. Merely the motivation was a little different." In this episode of For Future Reference, a new podcast from Institute for the Future, David Pescovitz and I talk with Griffith about how we need new mindsets as much as new technologies to alleviate climate change.
