Carbon emissions now more than double the planetary boundary, analysis finds
Earth is not infinite. Pollution beyond certain levels threatens the climate and ecosystems. To prevent this, scientists have proposed planetary boundaries, defining the safe operating limits of the Earth system. A KAIST research team recalculated climate change and nitrogen pollution using the same standard and found that current carbon emissions already exceed the planet's sustainable limit by more than double.

Sugarcane hits the sweet spot for sustainable carbon
When anyone talks about the future of sustainable aviation fuel, one question dominates: how do we replace fossil carbon without compromising food security or biodiversity? Experience leads some researchers to believe the answer is sugarcane.

Rising carbon dioxide levels now detected in human blood
Rising carbon dioxide levels are being detected within the human body, with new research warning a key blood marker for the gas could near its healthy limit within decades if current trends continue. The findings are especially relevant for children and adolescents, whose developing bodies will experience the longest cumulative exposure to rising atmospheric CO₂.

Keeping an eagle eye on carbon stored in the ocean
Geologic reservoirs that trapped petroleum for millions of years are now being repurposed to store the greenhouse gas carbon dioxide. New research is improving how we monitor this storage and verify how much CO2 these reservoirs have stored.

Mixing incentives and penalties found key to cutting carbon emissions long term
A study from a team of researchers that includes faculty from the University of California San Diego and Princeton University shows how a mix of subsidies for clean energy and taxes on pollution can significantly reduce greenhouse gas emissions that cause climate change.

Amid this news madness, I've thoroughly enjoyed being subscribed to the daily #CarbonBrief. Instead of compulsing the news, I try [and often fail] to focus on the most insightful items in my news feeds. This analysis of the latest UK auction for #WindPower was excellent:

Carney is a carbon industry plant.
nothing says environmental “blank cheque” to industry like: “voluntary certification program”.
"But operators have another compliance option, which some may find controversial because it could give industry players some more leeway. Operators can design their own approaches, providing a facility meets "methane intensity thresholds" that are on par with standards from "leading international voluntary certification programs.””
That's what private forest companies (Mosaic) on Vancouver Island use to claim they are following ‘best practices' as they clear cut whole sides of mountains and leave a 10m ‘riparian zone' around streams while falling trees right over them.
It's a license to make up their own rules and do whatever they want, wider impacts be damned.

University of Houston’s Carbon Capture Breakthrough Cuts Costs, but Scale Remains Uncertain | Happy Eco News
The University of Houston’s carbon capture researchers achieved 90% CO2 removal at $70 per ton using membraneless technology; however, scaling faces challenges related to cost, policy, and infrastructure.
