but it inevitably brings forth a mish-mash of half-remembered, inappropriate or out-of-date comparisons between the impacts of carbon dioxide and methane.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

In fact, in 1938 Sir George Simpson, a leading meteorologist, dismissed the link between rising carbon-dioxide (CO 2 ) concentration and temperature as “ rather a coincidence ”. The non-expert in question was Guy Callendar , a British steam engineer doing his own atmospheric research at home.

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.

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. Whenever there are combustion processes, of which there are many in our industrial society (e.g.,

There are other things that will get the headlines (the expected time before we get to 1.5ºC or 2ºC, the headline SLR numbers, the ‘unprecedented rate’ statement, constraints on climate sensitivity , carbon cycle feedbacks, the implications for the carbon budgets etc.), 1981) which can be seen here. 1, SPM, AR5.

not plants, animals, or bacteria), get their energy by breaking down organic molecules via a different chemical pathway than we air-breathers use to get our energy, which does not require oxygen and ends in methane instead of carbon dioxide and water.
