The CO2 problem in six easy steps (2022 Update)

Real Climate

Step 1: There is a natural greenhouse effect. Thus there must be a large amount of IR absorbed by the atmosphere (around 158 W/m 2 ) – a number that would be zero in the absence of any greenhouse substances. Step 2: Trace gases contribute to the natural greenhouse effect. The Earth’s Energy Budget (NASA).

Operationalizing Climate Science

Real Climate

Where, at the beginning, there was really only one input parameter (the CO 2 concentration) that needed to be coordinated, the inputs have now broadened to include myriad forcings related to other greenhouse gases, air pollution, land surface change, ozone, the sun, volcanoes, irrigation, meltwater etc. DeRepentigny, A. Jahn, and C.

CMIP6: Not-so-sudden stratospheric cooling

Real Climate

The dominant factors are changes in CO2 (a cooling), ozone depletion (a cooling), warming from big volcanoes, and oscillations related to the solar cycle. That means the greenhouse substances are basically just CO2 and ozone, and they absorb in quite different parts of the spectrum. The basic concept is easy to grasp though.

Congress Considers First-Ever Purchase Incentive for Commercial EVs

Union of Concerned Scientists

Last week, Senators Schumer and Manchin announced a compromise on a reconciliation bill, called the Inflation Reduction Act of 2022 , that includes significant climate and air quality progress and a goal to reduce greenhouse gas emissions nationwide by 40 percent by 2030. A key step towards addressing climate change and air quality.

Protecting Public Health Is Complicated. But Science Can Help, and the Time Is Now.

Union of Concerned Scientists

Incremental (step-by-step) approaches In 2022, the EPA published an Environmental Justice Legal Tools document and a Cumulative Impacts Addendum. Overburdened communities cannot wait any longer. The big question is how—and fortunately, we’re not starting from zero. Methods exist, and this body of work is growing.

Clauser-ology: Cloudy with a chance of meatballs

Real Climate

Some of you will have heard of John Clauser because he was an awardee of the 2022 Nobel Prize in Physics for his role in the experimental verification of quantum entanglement. Clauser however takes that number, removes 80 and 20 W/m 2 for atmospheric absorption by ozone (!!) John Clauser’s theory of climate explained. Schmidt, T.

Clean Fleets Rule Slated to Deliver Healthier Air for Californians

Union of Concerned Scientists

Trucks and buses on California’s roads and highways are responsible for the majority of lung-damaging fine particulate and ozone-forming nitrogen oxide emissions, and a sizable amount of climate-warming greenhouse gas emissions as well. Last November, the California Energy Commission approved $1.7
