Sentences with phrase «increase water vapour concentrations»

But, if global temperatures increase from man - made global warming, this could increase water vapour concentrations, potentially leading to more warming.

Not exact matches

Observational evidence indicates that the frequency of the heaviest rainfall events has likely increased within many land regions in general agreement with model simulations that indicate that rainfall in the heaviest events is likely to increase in line with atmospheric water vapour concentration.

Line - by - line computer code simulations show that a 10 % increase in CO2 concentration has the same effect as a uniform 1.80 % change in water vapour on the out - going longwave radiation.

The declining upper atmosphere water vapour allows heat to escape to space, offsetting the warming effect of increasing CO2 concentrations.

If CO2 concentration is increased and we assume no cloud or water vapour feedbacks (however evaporation is NOT a feedback — it is always a major determinant of surface temperature.)

Carbon dioxide differs from water vapour in that human activities can increase its atmospheric concentration.

Total water vapour in the atmosphere may increase as the temperature of the surface rises, but if at the same time the mid - to upper - level concentration decreases then water vapour feedback will be negative.

This is based on the increase in CO2 concentration needed to make the gas as effective as water vapour in absorbing LWIR ie based on equivalence:

This is based on the increase in CO2 concentration needed to make the gas as effective as water vapour in absorbing LWIR ie based on equivalence: For a product term PwL of 0.0231 * (4 * 3.281) ft.atm a water vapour absorptivity of o. 2 absorbs 84Wm - 2 of land LWIR in 4m.

Additionally, the Intergovernmental Panel on Climate Change's 2001 report notes that «global average water vapour concentration and precipitation are projected to increase during the 21st century.»
