"Amsterdam’s roofs have just been converted into a giant sponge that will make the city more climate resilient.
The Dutch have always been famous for their ability to control water, born out of the necessity of their homeland, much of which is below sea level.
Now, their expert water management skills are transforming the city skyline in the capital city of Amsterdam from one of terracotta tile, concrete, and shingles into green grass and brown earth.
It’s part of a new climate-resiliency trend in architecture and civic planning known as the ‘sponge city concept,’ in which a garden of water-loving plants, mosses, and soil absorbs excess rainwater before feeding it into the building for use in flushing toilets or watering plants on the ground.
If heavy rains are predicted, a smart valve system empties the stored rainwater into the municipal storm drains and sewers in advance of the weather, allowing the roof to soak up water and reduce flooding in the city.
In this way, the rooftops of buildings can be wrung out and filled up just like a sponge.
In Amsterdam, 45,000 square meters, or 11 acres of flat metropolitan rooftops have already been fitted with these systems, and the contracting firms behind the technology say they make sense in dry climates like Spain just as much as in wet climates like Amsterdam...
A 4-year project of different firms and organizations called Resilio, the resilient network for smart climate adaptive rooftops, rolled out thousands of square meters of sponge city technology into new buildings. As with many climate technologies, the costs are high upfront but tend to result in savings from several expenditures like water utilities and water damage, over a long-enough time horizon...
All together, Amsterdam’s sponge capacity is over 120,000 gallons.
“We think the concept is applicable to many urban areas around the world,” Kasper Spaan from Waternet, Amsterdam’s public water management organization, told Wired Magazine. “In the south of Europe–Italy and Spain–where there are really drought-stressed areas, there’s new attention for rainwater catchment.”
Indeed the sponge city concept comes into a different shade when installed in drought-prone regions. Waters absorbed by rooftops during heavy rains can be used for municipal purposes to reduce pressure on underground aquifers or rivers, or be sweated out under the Sun’s rays which cools the interior of the building naturally.
Additionally, if solar panels were added on top of the rooftop garden, the evaporation would keep the panels cooler, which has been shown in other projects to improve their energy generation.
“Our philosophy in the end is not that on every roof, everything is possible,” says Spaan, “but that on every roof, something is possible.”
Matt Simon, reporting on the Resilio project for Wired, said succinctly that perhaps science fiction authors have missed the mark when it came to envisioning the city of the future, and that rather than being a glittering metropolis of glass, metal, and marble as smooth as a pannacotta, it will look an awful lot more like an enormous sculpture garden."

This might be a hot take, but I actually like that Percy figured out Luke was the traitor at the last minute. There were A LOT of clues that would’ve been hard to ignore, and he ignored them for as long as he could. And it’s clear that even after accusing Luke, he’s still surprised and heartbroken at Luke’s confirmation of his suspicions. He was holding out hope, guys!!
Also, the Betrayal Scene flows better as an exchange of dialogue and a swordfight than it did, in the books, as a monologue and a scorpion sting. This also leaves a bigger impact on the viewers and characters because it’s more emotional.

Batman wearing a "Bruce Wayne's #1 H8r" shirt over his costume with a foam finger (but instead of a finger pointing up it's a thumbs down) that says the same thing and a matching baseball cap
The League desperately tries to defend Brucie Wayne
Batman does not care. He throws insults quicker than the league can make arguments. None of them know. Except one of them.
Superman knows. He stands in the back watching and he knows.
A singular tear runs down his cheek as he tries to keep his composure

"When a severe water shortage hit the Indian city of Kozhikode in the state of Kerala, a group of engineers turned to science fiction to keep the taps running.
Like everyone else in the city, engineering student Swapnil Shrivastav received a ration of two buckets of water a day collected from India’s arsenal of small water towers.
It was a ‘watershed’ moment for Shrivastav, who according to the BBC had won a student competition four years earlier on the subject of tackling water scarcity, and armed with a hypothetical template from the original Star Wars films, Shrivastav and two partners set to work harvesting water from the humid air.
“One element of inspiration was from Star Wars where there’s an air-to-water device. I thought why don’t we give it a try? It was more of a curiosity project,” he told the BBC.
According to ‘Wookiepedia’ a ‘moisture vaporator’ is a device used on moisture farms to capture water from a dry planet’s atmosphere, like Tatooine, where protagonist Luke Skywalker grew up.
This fictional device functions according to Star Wars lore by coaxing moisture from the air by means of refrigerated condensers, which generate low-energy ionization fields. Captured water is then pumped or gravity-directed into a storage cistern that adjusts its pH levels. Vaporators are capable of collecting 1.5 liters of water per day.

If science fiction authors could come up with the particulars of such a device, Shrivastav must have felt his had a good chance of succeeding. He and colleagues Govinda Balaji and Venkatesh Raja founded Uravu Labs, a Bangalore-based startup in 2019.
Their initial offering is a machine that converts air to water using a liquid desiccant. Absorbing moisture from the air, sunlight or renewable energy heats the desiccant to around 100°F which releases the captured moisture into a chamber where it’s condensed into drinking water.
The whole process takes 12 hours but can produce a staggering 2,000 liters, or about 500 gallons of drinking-quality water per day. [Note: that IS staggering! That's huge!!] Uravu has since had to adjust course due to the cost of manufacturing and running the machines—it’s just too high for civic use with current materials technology.
“We had to shift to commercial consumption applications as they were ready to pay us and it’s a sustainability driver for them,” Shrivastav explained. This pivot has so far been enough to keep the start-up afloat, and they produce water for 40 different hospitality clients.
Looking ahead, Shrivastav, Raja, and Balaji are planning to investigate whether the desiccant can be made more efficient; can it work at a lower temperature to reduce running costs, or is there another material altogether that might prove more cost-effective?
They’re also looking at running their device attached to data centers in a pilot project that would see them utilize the waste heat coming off the centers to heat the desiccant."

This is approximate since calculations vary, but somewhere in the neighborhood of 20% of carbon emissions since the Industrial Revolution have come from destruction of terrestrial ecosystems—wetland destruction, deforestation, degradation of grasslands and so on
Soil, soil communities, root systems, carbonate rock, wood, living plants, and peat in wetlands—all holds carbon
Now consider what plants do for you
The mere sight of plants and trees improves mental and physical health. I won't elaborate much more upon this, the positive effects are incredible and overwhelming.
Trees and vines that shade your home and outdoor areas: reduce the cost of cooling, meaning less electricity is used. Shade reduces the risk of death in extreme heat events.
(Trees also reduce light and noise pollution)
Edible plants (many wild plants and many plants you can grow): provide you with food reducing your dependence on industrial agriculture and cars to reach supermarkets
Community gardens and orchards: creates resilience and interdependence among small local communities, reducing the power of capitalism and increasing the ability of individuals to organize and create change. Makes more sustainable and plant based diets accessible to people for whom they would ordinarily be inaccessible
Compost piles for gardening: less greenhouse gas emissions than result from waste breaking down anaerobically in landfills
No more traditional lawns: much less use of gas powered lawn mowers, weed whackers etc. which are, by themselves, significant contributions to carbon emissions and urban pollution
Crafting and creating using plants: Locally available wild plant species can be used by local crafters and creators for baskets and containers, yarn, fabrics, dyes, and the like, resulting in less dependence on unsustainable and unethical global industries
More people growing and gathering edible and useful plants and using them = larger body of practical, scientific and technological insights to draw from in order to solve future problems
In conclusion: Plants
