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, but it inevitably brings forth a mish-mash of half-remembered, inappropriate or out-of-date comparisons between the impacts of carbon dioxide and methane.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. 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).

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.

The radiative forcing bar chart has gone full circle: Almost every IPCC report has a version of the radiative bar chart showing the contributions over the historical period of all the different forcings (greenhouse gases, aerosols, solar, etc.).

Repurposing Cropland Can Bring Environmental, Socioeconomic, and Water Justice to California

Union of Concerned Scientists

We estimated the potential of these buffer areas to contribute to reductions in water use, pesticide use, toxic nitrate leaching, and greenhouse gas emissions. Cropland repurposing that led to the reduction of fertilizer use and nitrate leaching would result in a reduction in greenhouse gas emissions (mostly nitrous oxide) equivalent to 2.2
