Sentences with phrase «radiative effect of carbon dioxide»

Humans are significantly altering the global climate, but in a variety of diverse ways beyond the radiative effect of carbon dioxide.

We both agree that the radiative effect of carbon dioxide, methane and sulphates are first order climate forcings.

Not exact matches

Four and a half billion years after its birth, the shrouded planet is much too hot to support the presence of liquid water on its surface because of its dense carbon dioxide atmosphere and sulfuric acid clouds, which retain too much radiative heat from the Sun through a runaway greenhouse effect.

Between 1990 and 2015, the bulletin says, there was a 37 percent increase in radiative forcing — the warming effect on the climate — because of long - lived greenhouse gases such as carbon dioxide, methane and nitrous oxide from industrial, agricultural and domestic activities.

The radiative forcing (IPCC 2007) is about 1.6 W m − 2 for both carbon dioxide increases alone and also the total with all other effects included (0.6 — 2.4 as 95 % confidence limits), and the net energy imbalance of the planet is estimated (Trenberth et al. 2009) to be 0.9 ± 0.5 W m − 2.

This unique feature of the Antarctic atmosphere has been shown to result in a negative greenhouse effect and a negative instantaneous radiative forcing at the top of the atmosphere (RFTOA: INST), when carbon dioxide (CO2) concentrations are increased, and it has been suggested that this effect might play some role in te recent cooling trends observed over East Antarctica.

It is because of these effects of partial saturation that the radiative forcing is not proportional to the increase in the carbon dioxide concentration but shows a logarithmic dependence.

As noted earlier, the IPCC's latest report indicates that the current radiative forcing of non-carbon dioxide greenhouse gases and aerosols effectively cancel each other, so that the net effect of all radiative forcing components is currently roughly equal to the effect of carbon dioxide alone.

For example, the direct radiative effect of a mass of methane is about 84 times stronger than the same mass of carbon dioxide over a 20 - year time frame [22] but it is present in much smaller concentrations so that its total direct radiative effect is smaller, in part due to its shorter atmospheric lifetime.

c The GWP, or the Global Warming Potential, is used to contrast the radiative effects of different greenhouse gases relative to carbon dioxide.
