The CO2 problem in six easy steps (2022 Update)

Real Climate

Step 1: There is a natural greenhouse effect. This means that there is an upward surface flux of IR around (~398 W/m 2 ), while the outward flux at the top of the atmosphere (TOA) is roughly equivalent to the net solar radiation absorbed (~240 W/m 2 ). Step 2: Trace gases contribute to the natural greenhouse effect.

A Quick Science Refresher on Greenhouse Gas

Greenbuilding Law

With the federal government and state of Maryland each having announced within days of each other, the mandated disclosure of greenhouse gas (GHG) emissions, we have received, maybe not surprising, many calls in the last two weeks inquiring “what are GHGs?” Simply put, gases that trap heat in the atmosphere (.

A distraction due to errors, misunderstanding and misguided Norwegian statistics

Real Climate

A friend asked me if a discussion paper published on Statistics Norway’s website, ‘ To what extent are temperature levels changing due to greenhouse gas emissions? ’, was purposely timed for the next climate summit ( COP28 ). I don’t know the answer to his question. But this discussion paper is problematic for sure.

New EPA Proposal to Augment Methane Regulations Would Help Achieve an 87% Reduction From the Oil and Gas Industry by 2030

Inside Climate News

Steep reductions in emissions of methane—which traps 81 times as much heat as carbon dioxide in the first 20 years in the atmosphere—are among the most important steps for slowing climate change in the short term. oil and gas sector by 87 percent below 2005 levels by the end of the decade, the agency said.

Soil carbon sequestration has to look beyond the field to be effective

HumanNature

Mechanisms of climate mitigation via soil carbon sequestration At the root of the excitement around soils is their ability to hold on to carbon, potentially drawing it out of the atmosphere and locking it away. They present a serious sink for atmospheric carbon to be stored. So why the hype around agricultural soils?

How not to science

I had reason to be reviewing the history of MSU satellite retrievals for atmospheric temperatures recently. McNider, "Satellite greenhouse signal", Nature , vol. A trip down memory lane and a lesson on scientific integrity. The version of the MSU2R product at the beginning of 2014 was version 5.5, and that had a raw trend of -0.01
