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.

He, however, goes seriously off the rails when he estimates the impact of clouds on the radiation budget. We can measure directly how much solar radiation arrives at the Earth and once you spread it over the surface of the Earth, there is about 340 W/m 2.

Guest Post By Erin Boedicker , 2020-2021 Sustainability Leadership Fellow and Ph.D. When fuels are burned to create energy in a process called combustion, black carbon along with carbon monoxide and other compounds are created because there is not enough oxygen in the atmosphere for the reaction to go to completion.

“If I look at the next 50 years, next hundred years maybe, nobody will be able to set up a telescope that’s powerful enough to resolve surface features,” says Jonathan Jiang , an atmospheric scientist at NASA’s Jet Propulsion Laboratory in Pasadena, California, who uses Earth as a laboratory to model exoplanets.
