Sentences with phrase «impact of water vapour»

If an increase of 5 % in CO2 results in an increase of 1 % in water vapour, and if water vapour has say 30x the influence of CO2 on heat trapping, then a 1 % increase in CO2 will result in an increase of 30/5 = 6 % in the heat trapping impact of water vapour.

This exclusion is ridiculous, not least because aircraft emissions have a particular role in heating the planet, due to the height at which they are released, and the multiplying impacts of the water vapour and other gases the planes produce.

Not exact matches

A new computer simulation suggests that the water vapour and sea salt thrown up by the impact could damage the Earth's protective ozone layer, leading to record levels of ultraviolet radiation that could threaten human civilisation.

Elisabetta Pierazzo of the Planetary Science Institute in Tucson, Arizona, and colleagues used a global climate model to study how water vapour and sea salt thrown up from an impact will affect ozone levels for years after the event.

Forster, P.M. de F., and K.P. Shine, 2002: Assessing the climate impact of trends in stratospheric water vapour.

The increase in water vapour as the surface warms is key, but so might be changes in boundary layer stability, rossby wave generation via longitudinally varying responses at the surface, impacts of the stratopshere on the steering of the jet, and the situation is completely different again for tropical storms.

To be sure, some of these effects (such as the impact of irrigation on surface water vapour, or land use changes on evapotranspiration) are not easily dealt with in terms of the tropospheric radiative forcing — a point that was well made in the National Academies report on radiative forcing (on which Dr. Pielke was an author).

However, the contributions of water vapour / lapse rate and surface albedo feedbacks to sensitivity spread are non-negligible, particularly since their impact is reinforced by the mean model cloud feedback being positive and quite strong.

With warm oceans releasing more water vapour, we saw floods of biblical proportions hit the agricultural regions of Queensland, killing 22 people and impacting an area larger than France and Germany.

As far as water vapor in the tropics, they even say» In the humid equatorial regions, where there is so much water vapour in the air that the greenhouse effect is very large, adding a small additional amount of CO2 or water vapour has only a small direct impact on downward infrared radiation.»

In the humid equatorial regions, where there is so much water vapour in the air that the greenhouse effect is very large, adding a small additional amount of CO2 or water vapour has only a small direct impact on downward infrared radiation.

As reported by the IPCC in the Physical Science Basis, «In the humid equatorial regions, where there is so much water vapour in the air that the greenhouse effect is very large, adding a small additional amount of CO2 or water vapour has only a small direct impact on downward infrared radiation.

â $ œEven doubling or tripling the amount of carbon dioxide will virtually have little impact, as water vapour and water condensed on particles as clouds dominate the worldwide scene and always will.â $ â $ ``.

Methane is an important part of the anthropogenic radiative forcing Methane emissions have a direct GHG effect, and they effect atmospheric chemistry and stratospheric water vapour which have additional impacts natural feedbacks involving methane likely to be important in future — via wetland response to temperature / rain change, atmospheric chemistry and, yes, arctic sources There are large stores of carbon in the Arctic, some stored as hydrates, some potentially convertible to CH4 by anaerobic resporation [from wikianswers: Without oxygen.

But it was cold this winter and C02 is plant food and only a trace gas and the greenhouse effect has been disproved anyway and even if the greenhouse effect does exist, C02 has negligible impact compared to water vapour and our only source of heat is the sun so it must be the sun, unless it is due to the C02 from volcanoes, but C02 follows warming so it can't be the C02 and the medieval warm period was warmer anyway and all the temperature reconstructions that show this not to be true are produced by corrupt scientists being paid by corrupt governments that have colluded to create an excuse to form a one world unelected social - ist government and even if the scientists are not that corrupt, although the e-mails prove they are, they have still got it wrong as the climate sensitivity is not as high as they think it is because it is basically the planets orbits and cosmic rays so we can say for a fact that the warming that probably does not exist is definatley not due to humans and even if it was the evidence is not sufficient to make drastic changes to the economy and increase taxes so that the politicians and scientists and business leaders get rich and leave us all poor — do they think we are stupid or something?

Tyndall's main interest was with water vapour and its impact on radiation, but he also dealt with the radiative forcing of other greenhouse gases including carbon dioxide.

There is next to nohing nothing in the TAR on precipitation modelling yet the cycle of evaporation > water vapour > clouds > precipitation is at the heart of quantifying the anthropogenic impact.
