CMIP6: Not-so-sudden stratospheric cooling

Real Climate

So SSU me Like MSU trends, these records reflected a weighted average of atmospheric temperatures, and the three SSU channels progressively weight higher levels in the stratosphere, roughly centered on 30km, 40km and 45km above the surface but with quite a bit of overlap.

Antarctic extreme events: ‘All-time records are being shattered not from decades ago, but from the last few years and months’

Frontiers

Writing as part of Frontiers’ guest editorials series, the study’s lead author – Prof Martin Siegert, deputy vice chancellor of the University of Exeter (Cornwall) – discusses how without there being a rapid shift to net-zero greenhouse gas emissions by 2050, the Antarctic environment will experience ever more drastic changes.

Susannah Pierce: A Climate Villain Painting Big Oil Green

Enviromental Defense

Just days before the conference she was featured in an article where she attempted to shift blame away from the fossil fuel industry by saying that oil companies can only decarbonize as fast as the rest of the economy – a comment that completely ignores the fact that the oil and gas industry is Canada’s largest source of greenhouse gas emissions.

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

Union of Concerned Scientists

Under the LCFS each fuel pathway gets a unique carbon intensity (CI) based on a lifecycle analysis of the greenhouse gas emissions associated with the production and use of the fuel. dairy herds fell by more than half between 2002 and 2019, with an accelerating rate of decline in 2018 and 2019, even as milk production continued to grow.”

The Bottom Line: Are incentives enough to offset the costs of “carbon-smart” farming practices?
