A study which says that irrigation has caused 0.1 % of warming to be blunted by
increasing available moisture isn't telling the complete story unless it also includes warming increases due to draining of wetlands.
Not exact matches
Increasing heat is also warming up the ocean, and hotter air holds onto more moisture, increasing the available energy for h
Increasing heat is also warming up the ocean, and hotter air holds onto more
moisture,
increasing the available energy for h
increasing the
available energy for hurricanes.
New Zealand experienced an extreme two - day rainfall in December 2011; researchers said 1 to 5 percent more
moisture was
available for that event due to climate change, which is
increasing the amount of water vapor in the atmosphere.
In general, climate scientists expect heavy downpours to
increase over the U.S. and elsewhere, as a warmer atmosphere can hold more
moisture, making more of it
available to fall as rain.
Global warming had
increased the amount of atmospheric
moisture available to condense into rain, and La Niña, a circulation pattern that can produce heavy rains in Pakistan, was in progress.
But also keep in mind that Lambeck et al (2002) have suggested that loss of permanent ice over the Arctic Sea at the end of the last interglacial allowed for
increased accumulation of snow and ice at high latitudes because of the
increased amount of
moisture available.
The study said the changes in extreme wet and dry spell characteristics are supported by
increases in convective
available potential energy and low - level
moisture convergence.
So potentially you would have more
moisture available to this storm, just because the oceans are hotter because of global warming — and that could potentially
increase the impacts of a storm like this.
Global analyses show that the amount of water vapor in the atmosphere has in fact
increased due to human - caused warming.8, 9,10,11 This extra
moisture is
available to storm systems, resulting in heavier rainfalls.
Without a corresponding change (i.e.,
increase) in precipitation, this leads to a reduction of plant
available soil
moisture which
increases plant water stress through the growing season, thereby reducing GPP.
This is a logical result of the fact that a warmer Earth will have
increased evaporation from the oceans, and thus more
moisture will be
available for precipitation.
Using a simple physical model, O'Gorman suggests that this is due to the balance between two competing effects caused by the warming:
increasing moisture available for humidity and the decreases in the fraction of precipitation that falls as snow.
This, in turn,
increases the amount of atmospheric
moisture that is
available for storms to process into rainfall.
A consequence of
increased heating from the human - induced enhanced greenhouse effect is
increased evaporation, provided that adequate surface
moisture is
available (as it always is over the oceans and other wet surfaces).
In contrast,
increased thaw depth and
increased water - use efficiency under elevated CO2 will tend to
increase available soil
moisture, decreasing fire frequency and
increasing woody biomass.
