The phrase
"amount of water vapor in the atmosphere" means how much water is in the air around us.
Full definition
Trenberth notes that global warming has already increased the
average amount of water vapor in the atmosphere by about 4 %, «extra moisture flowing into the storms that produced the heavy rains and likely contributed to the strength of the storms through added energy.»
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.
That question was answered last year, when the United States and Cuba began operating a newly installed Global Positioning Satellite (GPS) system in Camagüey, Cuba, designed to measure
the amount of water vapor in the atmosphere above the region.
Of course,
the amount of water vapor in the atmosphere is also affected by another potent greenhouse gas — methane — which has unexpectedly failed to increase in recent years.
By analyzing global water vapor and temperature satellite data for the lower atmosphere, Texas A&M University atmospheric scientist Andrew Dessler and his colleagues found that warming driven by carbon dioxide and other gases allowed the air to hold more moisture, increasing
the amount of water vapor in the atmosphere.
They also found that the speed at which the sharp tips of snowflakes grow is directly proportional to
the amount of water vapor in the atmosphere.
For every 1 °C (1.8 °F) of warming,
the amount of water vapor in the atmosphere increases by about 7 percent.
Research shows that
the amount of water vapor in the atmosphere has already increased.
That's because reorganization likely wouldn't maintain the same average
amount of water vapor in the atmosphere (it's the most important «greenhouse gas,» not carbon dioxide or methane).
This lesson explores the relationship between
the amount of water vapor in the atmosphere available for precipitation and actual precipitation levels.
Global analyses show that
the amount of water vapor in the atmosphere has in fact increased over both land and oceans.10, 11,12,13 Climate change also alters dynamical characteristics of the atmosphere that in turn affect weather patterns and storms.
There has never been anything that has ever shown
the amount of water vapor in the atmosphere is dependent on the CO2 concentration.
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.
The amount of water vapor in the atmosphere exists in direct relation to the temperature.
If the earth is warmed by 1 degree Celsius, then
the amount of water vapor in the atmosphere increases by 7 percent.
This finding was supported by many other independent lines of evidence, such as the retreat of snow and sea - ice cover, the widespread melting and retreat of glaciers, the rise in sea - level, and the increase in
the amount of water vapor in the atmosphere.
For every 1 °C (1.8 °F) of warming,
the amount of water vapor in the atmosphere increases by about 7 percent.
The amount of water vapor in the atmosphere varies a lot with altitude and temperature.
Another is,
the amount of water vapor in the atmosphere is increasing because the atmosphere is getting warmer, and therefore the amount of water being dumped during these storms is larger because of the human, global - made — global warming, human - made global warming, which is now more than 1 degree Celsius.
They posit a «feedback loop» in which carbon dioxide increases temperatures, which increases
the amount of water vapor in the atmosphere, which increases temperatures even more.
Somehow weve got to reduce
the amount of water vapor in the atmosphere.
However, it should be obvious from the image where water vapor is about 90 % of the image width that doubling
the amount of water vapor in the atmosphere will not cause 180 % of the available energy to be absorbed.
If
the amount of water vapor in the atmosphere was increasing while the temps were increasing, IT WAS WORSE THAN WE THOUGHT!!
If
the amount of water vapor in the atmosphere declined slightly over the last 10 years while the temps were relatively flat, we actually LOST energy while CO2 was increasing.
The main reason for this is that warming enhances
the amount of water vapor in the atmosphere, which then snows - off in the dry and cold polar region where it releases energy and warms the atmosphere.
Water vapor is responsible for the major feedback, increasing sensitivity from 1 C to somewhere between 2 and 4.5 C. Water vapor is itself a powerful greenhouse gas, and
the amount of water vapor in the atmosphere is in part determined by the temperature of the air.
Depending on
the amount of water vapor in the atmosphere, this transmittance will reduce.
This varies with
the amount of water vapor in the atmosphere.
«Global analyses show that
the amount of water vapor in the atmosphere has in fact increased due to human - caused warming.
