- 1Earth crosses seven of nine planetary boundaries, scientists warn●and the models behind climate plans may be too optimistic Land carbon uptake has stalled Changing energy and food comes
Earth has now crossed seven of the nine planetary boundaries that define a safe operating space for humanity, researchers say. New reporting points to stalled land carbon uptake, meaning forests and soils may be absorbing less CO2 than assumed, and warns that the models underpinning many national climate plans may be too optimistic. Commenters stress that changing energy and food systems must come first.
- 2New battery-based device captures CO2 using less energy●A new device captures CO2 by pumping it across a battery, requiring less energy than current carbon capture systems http
Researchers have developed a device that captures carbon dioxide by pumping the gas across a battery, an approach that requires less energy than existing carbon capture systems. The technology, reported by Ars Technica, could make direct air capture cheaper and more practical for tackling industrial emissions. Early coverage highlights it as a promising advance in climate and energy technology.

Researchers have developed a new device that captures carbon dioxide by pumping it across a battery, requiring less energy than existing carbon capture systems. The design, covered by Ars Technica, could make direct CO2 removal from air or emissions more efficient and cheaper, a key step for climate mitigation. Coverage is drawing interest from science and climate communities focused on energy costs of carbon capture technology.
- 4CO2 levels up nearly 40% in one lifetime, post notes●When I was born CO2 concentration was 311 ppm. Now it is ~430 ppm, around a 38% increase. And that's just CO2. # Climate
A widely shared observation points out that atmospheric carbon dioxide has risen from roughly 311 parts per million to about 430 ppm within one person's lifetime, an increase of around 38%. The comparison, framed through a personal lifespan, underscores how quickly greenhouse gas concentrations have climbed, and commenters are using the figure to highlight the scale of human-driven climate change.
- 5Lobbyists push EU to roll back regulations●Lobbyisten bedrängen die # EU , sie wollen Regulierungen wieder abbauen, um freie Hand zu haben. Ob # CO2 - Handel, # Li
Lobbyists are pressuring the European Union to weaken or dismantle existing regulations so companies can operate with fewer restrictions. Critics say targets include the CO2 emissions trading system, the supply chain law, consumer protection, data privacy rules, and pesticide restrictions, warning that pesticides could return to fields and food. Commentators argue this serves corporate profit at the expense of public health and environmental safeguards.
- 6Hemp promoted as sustainable building material●RE: https:// mastodon.social/@Karl_Theodor/ 117115878211084671 🌱 😀 👯 🧱 # Cannabis als nachhaltiges # Baumaterial : die #
A German-language post is arguing that cannabis, specifically hemp, could become the building material of the future for ecological construction. It opens with the striking claim that around 40 percent of global CO2 emissions come from the construction industry, presenting hemp-based materials as a way to cut that footprint. The post is being shared among users interested in green building and climate solutions, drawing modest engagement.
- 7EU car emissions targets contrast sharply with loosened US rules●The European Union has set a target for car emissions of 93.6g CO2/km (2025-2029), 49.5g CO2/km (2030-2034) and 0g CO2/k
The European Union has set fleet-wide car emissions targets of 93.6g CO2/km for 2025-2029, 49.5g CO2/km for 2030-2034, and zero from 2035 onwards. The United States under the Trump administration has moved in the opposite direction, loosening its rules to permit fleet averages of roughly 157g CO2/km. Commenters highlight the growing transatlantic divide on vehicle climate policy.
- 8EU auctions 2.792 million carbon permits at 84.87 euros▼European Union auctions 2.792 mln spot carbon permits at 84.87 eur/t
The European Union auctioned 2.792 million spot carbon permits under its emissions trading system at a clearing price of 84.87 euros per tonne. The sale is a routine weekly supply of allowances that power plants and industrial firms must hold to cover their CO2 emissions, and the price level is being watched as an indicator of carbon market conditions in Europe.
