My novel is set in the near future, and I used this nifty tool from IPCC/ NASA to see what their climate futures look like. The five sections on the right are different scenarios - bottom one is best case if we start taking massive action to decarbonize today. #clifi #scifi #author #greensky

Looking forward to reading @doctorvive.bsky.social 's new book. If you're in #NY, check out either of these event s- one with @eroston.bsky.social the other with David Wallace-Wells. #greensky #climatesky #publicationday #author
On July 10th, THE LANGUAGE OF CLIMATE POLITICS will be launched into the world! ✨ And I will be doing *two* events to celebrate! The first one will be a 1pm event at the UN with @eroston.bsky.social. 1/7

Core sediment samples show West Antarctica was likely river delta or estuary during Eocenephys.org By testing core samples, an international team of geoscientists and geologists has found evidence that much of what is now West Antarctica was a river delta or estuary 34 to 44 million years ago.

From 1978 to 2022, CEO pay grew by 1,209% while the typical worker's pay rose just 15%. This explosion in CEO pay relative to the pay of average workers isn’t because CEOs have become so much more valuable than before. They've just gamed the system to line their pockets.

Today in #Antarctic news... It's back.... the hole in the ozone layer: not gone, not forgotten. Although CFC phase-out helped, there's still a hole and critters are getting sunburned. Proposed climate-cooling geoengineering "would also deplete ozone." #iceicebaby 🐧🇦🇶 #cliamtesky #science #greensky

Great lessons from owls and maple seeds making wind turbines quieter and more efficient. I love biomimicry - so interesting to learn from nature. www.youtube.com/watch?v=3Vtb...
How Owls and Maple Seeds Are Revolutionizing Wind Turbineswww.youtube.com In this video, we delve into the world of renewable energy and the innovative ways in which companies like Biome Renewables are making less disruptive and more efficient wind turbines by using nature as their inspiration. Wind turbines have been a vital source of green energy for many years, providing power to millions of homes and businesses across the globe. However, even modern wind turbines can be made more efficient and environmentally friendly. Biome Renewables is one such company that is looking to nature for inspiration on how to achieve this goal. We’ll explore how Biome Renewables has developed its "FeatherEdge" technology, inspired by the silent flight of owls, to reduce noise levels by up to 80 percent. The specialized fringe along the trailing edge of the turbine blades forces air to mix at specific locations, muffling the sound of air flowing around them. This allows for more efficient wind turbines, as they can spin slightly faster in wind of the same speed, generating more power. In addition to the FeatherEdge technology, Biome Renewables has also developed the "PowerCone" device, which channels air back onto the blades, increasing efficiency and electricity-generating ability. This device is modeled after the falling maple seed, which redirects the wind along its slender length, accelerating flow towards the tip, and allowing it to remain aloft longer. By looking to nature, companies like Biome Renewables can find elegant solutions that maximize the power of the wind while minimizing any negative impacts on the environment.

Today in #Antarctic news... Got feedback? Yep. New study: "Our findings suggest a positive feedback loop: as the ice shelf melts more rapidly, more freshwater is produced, leading to a stronger undercurrent and more heat being transported toward the ice shelves." #iceicebaby 🐧🇦🇶 #greensky #science
Feedback loop that is melting ice shelves in West Antarctica revealedphys.org New research has uncovered a feedback loop that may be accelerating the melting of the floating portions of the West Antarctic Ice Sheet, pushing up global sea levels.

Today in #Antarctic news... "As the Antarctic desert gets less arid ... changing conditions would favour phototrophic microbes over chemotrophic ones. Chemotrophs play a role in carbon sequestration." Their loss may accelerate local climate warming. #iceicebaby 🐧🇦🇶. #science #climatesky #greensky

This is so cool: vacuum trash disposal network. Link in case the original doesn't post in your region: vimeo.com/256040766
In Bergen, Norway, there are no garbage trucks and no trash piling up on streets because all over town, there are receptacles that connect to an UNDERGROUND PNEUMATIC WASTE TRANSPORT SYSTEM. The waste collects for a bit, and then WHOOSH...it's off to the recycling center. 🤯
How Bergen solved its escalating waste problemvimeo.com Why did Bergen leave the waste bins behind and changed to Envac's automated waste collection system? Are the citizens happy? How is the project coming along?…
