The CO2 problem in six easy steps (2022 Update)

Real Climate

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.

New misguided interpretations of the greenhouse effect from William Kininmonth

Real Climate

He made some rather strange claims, such as that the Intergovernmental Panel on Climate Change (IPCC) allegedly should have forgotten that the earth is a sphere because “ most absorption of solar radiation takes place over the tropics, while there is excess emission of longwave radiation to space over higher latitudes ”. 679-688, 2016.

The definitive CO2/CH4 comparison post

The radiative forcing from these changes in concentrations can be easily calculated using standard formulas (from Etminan et al, 2016 which supersede the slightly simpler ones from IPCC TAR), as about 2 W/m 2 for the CO 2 change and 0.65 W/m 2 for CH 4. W/m<sup>2</sup> (to about 60% of the CO 2 effect since 1750). References.

are used all over the world, based on calculations that quantify the effects of physical mechanisms and the way different parts of the atmosphere are connected to each other. The physics-based models describe how energy flows through the atmosphere and ocean, as well as how the forces from different air masses push against each other.

Now however, the updates to the historical warming , the use of four datasets instead of one, and of course, the series of record breaking years subsequently (2014, 2015, 2016/2020), the issue of variability in decadal trends is no longer so salient. 1981) which can be seen here.
