but it inevitably brings forth a mish-mash of half-remembered, inappropriate or out-of-date comparisons between the impacts of carbon dioxide and methane. Thus despite the smaller concentrations and changes in methane compared to carbon dioxide, the impacts are comparable. W/m 2 for CH 4. Stocks and flows.

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).

(Figure 1) These properties are a double-edged sword: while they are the root of the problems that black carbon causes, they also make mitigating black carbon one of the most actionable ways to fight climate change.
