The definitive CO2/CH4 comparison post

Real Climate

, but it inevitably brings forth a mish-mash of half-remembered, inappropriate or out-of-date comparisons between the impacts of carbon dioxide and methane. So this is an attempt to put all of that in context and provide a hopefully comprehensive guide to how, when, and why to properly compare the two greenhouse gases.

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.

Deciphering the ‘SPM AR6 WG1’ code

Real Climate

I think in hindsight that my concerns from 2013 to some extent were supported by the fact that the IPCC organised an Expert Meeting on Communication, Oslo, Norway, 9–10 February 2016. The cause of our changing climate is the increase in atmospheric greenhouse gas concentrations that we have released into the air.

Why Energy Bills Will Be Even Higher This Winter

Union of Concerned Scientists

Oil and gas major ConocoPhillips’ website says gas is “one of the safest and cleanest fuels available” and that when it is burned, it “produces mostly carbon dioxide and water vapor—the same substances emitted when humans exhale.” Methane is also a fast-acting greenhouse gas in terms of its impact on the climate.
