Will UN Climate Talks in Azerbaijan Deliver on Finance and Emission Reductions? 

Union of Concerned Scientists

UCS is advocating for the US to commit to cutting its emissions at least 70% below 2005 levels by 2035, a level that can be met if we implement additional strong policies (beyond the Inflation Reduction Act and other existing federal and state policies) to accelerate the deployment of renewable energy and the phase out of fossil fuels.

since the 1850-1900 baseline is very clearly associated with the increases in greenhouse gases, slightly (and decreasingly) modulated by the changes in atmospheric pollution.

The CO2 problem in six easy steps (2022 Update)

Real Climate

The fact that there is a natural greenhouse effect (that the atmosphere restricts the passage of infra-red (IR) radiation from the Earth’s surface to space) is easily deducible from; i) the mean temperature of the surface (around 15ºC) and, ii) knowing that the planet is normally close to radiative equilibrium. in IPCC TAR).

New study suggests the Atlantic overturning circulation AMOC “is on tipping course”

Real Climate

The paper results from a major computational effort, based on running a state-of-the-art climate model (the CESM model with horizontal resolution 1° for the ocean/sea ice and 2° for the atmosphere/land component) for 4,400 model years.

Has Gasoline Use in California Peaked?

Union of Concerned Scientists

Despite adding six million more passenger cars, trucks, and SUVs to the roads over the last 10 years, California’s gasoline consumption has dropped over two billion gallons from its peak in 2005. Gasoline use per person has also fallen, from 445 gallons per year per person in 2005, to under 350 gallons per year per person in 2024.

What’s the Role of the Land Carbon Sink in Achieving US Climate Goals?

Union of Concerned Scientists

Without the considerable carbon absorption capacity of our lands (and oceans), we’d currently have much more CO 2 in the atmosphere and an accelerated timeline of warming. Both gradual and abrupt thaw can release huge amounts of methane and carbon dioxide into the atmosphere, further exacerbating warming.
