Planets in Alpha Centauri could be carbon-rich – if they exist

Physics World

Planets orbiting the Sun-like stars of Alpha Centauri could be carbon-rich worlds with diamonds and graphite littered across their surfaces, say astronomers. So far, astronomers have discovered one confirmed exoplanet (and two strong candidates) orbiting Proxima, but a 2012 “discovery” of a planet orbiting Centauri B was later disproven.

Something Stinks: California Must End Manure Biomethane Accounting Gimmicks in its Low Carbon Fuel Standard

Union of Concerned Scientists

Each credit one metric ton of carbon dioxide equivalent pollution below the standard. I’ve written recently about why a Cap on Vegetable Oil-Based Fuels Will Stabilize and Strengthen California’s Low Carbon Fuel Standard , which addresses the bio-based diesel credits.

The Real Cost of Food

Acoel

This land used to be vast wetlands, native grass-covered prairie, or forest — natural systems adept at storing carbon, producing abundant wildlife, and filtering polluted water but over time has been converted for agricultural use. For example, between 2007 and 2012, 7.8 Nitrous oxide is even more damaging to our atmosphere.

COP28: “The Methane COP”

Legal Planet

This shift is good news because tackling methane is crucial to the fight against climate change due to its significantly higher global warming potential than CO2, the disposal of relatively cheap methods of controlling emissions, and its short atmospheric lifespan. Notwithstanding, COP’s outcomes are still important.

Analysis: Moving the dial on ocean-based CO2 removal

A Greener Life

It’s now widely acknowledged that to avoid catastrophic climate change we’ll need to physically remove CO2 from the atmosphere. Yet the technologies needed to do this, collectively known as carbon dioxide removal (CDR), remains nascent, underfunded and largely unregulated.

The summary for policymakers of the Intergovernmental Panel on Climate Change sixth assessment reports synthesis

Real Climate

Nevertheless, the summary for policymakers states the need for “rapid and deep and, in most cases, immediate greenhouse gas emissions reductions in all sectors this decade” if we want global warming to keep below 1.5°C I had to look up the acronym “CDR” (Carbon dioxide removal). C or 2°C since preindustrial times (p.

AR6 of the best

Real Climate

Extremes : Back in 2012, the literature assessed by AR5 connecting changes in extremes to climate change was scant. As one example, the rate of warming over the past 15 years (1998–2012; 0.05 [–0.05 to 0.15] °C per decade), which begins with a strong El Niño, is smaller than the rate calculated since 1951 (1951–2012; 0.12 [0.08
