Weekly Solarpunk, of 29 May: Climate Scenario Shift, Earth-Sheltered Housing, Underwater Biospheres, Private Nature Reserve

Weekly Solarpunk for 29 May follows 6 future-facing stories and member reactions, including Climate Scenario Shift, Earth-Sheltered Housing, Underwater Biospheres, Private Nature Reserve. 1. Climate Scenario Shift Scientists have pushed the worst-case climate scenario off the table, but the article argues that this is only a sign of partial progress, not safety. According to The Conversation, action has reduced the odds of the most extreme path, yet the next few years still determine whether the world lands in a much harsher future or something closer to the best case. Source link 2. Earth-Sheltered Housing The post highlights a concrete, partially buried home as a practical answer to tornadoes and extreme heat. According to Kirsten Dirksen's video, the design uses earth as insulation and protection while also lowering heating and cooling costs. Source link 3. Underwater Biospheres The post points to Italy's underwater biospheres, called Nemo Gardens, and asks how they might compare with liveaboard stories in fiction. According to the linked ScienceDirect paper, the concept has been around since 2012, which is part of why the idea feels more developed than a casual novelty. Source link 4. Private Nature Reserve An Australian billionaire technology investor and his partner are donating $10 million to buy 7,000 hectares of cattle and logging land in the Great Dividing Range and turn it into a nature reserve. According to the article, the plan would protect tall moist forest, rainforest-clad gorges, wild rivers, and threatened species, but commenters mostly treated it as a small good outcome wrapped in a larger problem. Source link 5. Renewables Beat Gas Wind and solar generated more electricity than gas worldwide in April 2026 for the first time, a milestone reported by Ember Energy. According to Ember Energy, the monthly crossover shows renewables briefly outpacing gas on a global basis, though the post itself does not add extra detail beyond the headline. Source link 6. Solar Water Recovery A sun-powered desalination system is being presented as a way to make fresh water while also recovering lithium from seawater or brine. According to Interesting Engineering, the device couples water production with mineral recovery, but the practical scale and economics are still the real test. Source link That's it for today.
