So the rising trend in the lower curve is going to represent much
more water vapor added to the atmosphere than the declining top curve represents as leaving it.
Not exact matches
Prior to an eruption, gases —
water vapor, carbon dioxide, and sulfur dioxide — bubble out of the magma as it rises,
adding more pressure to the volcanic system, she explains.
I ask this because, theoretically, given a relatively closed system, with heat energy being
added, thermal expansion and contraction of gas and
water vapor,
more wind speed,
more shouldn't this also mean
more extreme weather?
Words only have meaning in context and while it may be true that
water vapor is a greenhouse gas in the sense that
more of it in the atmosphere will absorb
more infrared radiation and warm the climate, it is not a greenhouse gas in the sense that it is a gas we need to seriously worry about
adding directly to the atmosphere.
(PS regarding Venus — as I have understood it, a runaway
water vapor feedback would have occured when solar heating increasing to become greater than a limiting OLR value (Simpson - Kombayashi - Ingersoll limit — see http://chriscolose.wordpress.com/2010/08/23/climate-feedbacks-part-1/ — although I should
add that at
more «moderate» temperatures (warmer than today), stratospheric H2O increases to a point where H escape to space becomes a significant H2O sink — if that stage worked fast enough relative to solar brightening, a runaway H2O case could be prevented, and it would be a dry (er) heat.
You know the science behind it's called the green house effect when the sun beams down on the earth to provide energy to plants after that it reflects out to space but CO2, H2O (
Water Vapor), and AO2 capture these particles and keep them in the earth
adding more heat to the earth.
Even arbitrary scenarios could be constructed, built on reanalyses; for instance,
adding 10 %
more water vapor on the lateral boundaries of a Type 2 downscaling run.
This snowpack accumulation near the poles, which gets its
water via the Arctic and Antarctic oceans, that in turn rob it from equatorial latitudes of our oceans, also results in a reduction in the earth's spin axis moment of inertia and causes the spin rate to increase as evidenced in the recent history of the rate at which Leap Seconds are
added to our calendar (see Wysmuller's Toucan Equation for
more on this evidence that during this warm time with much greater polar humidity, earlier seasonal, later seasonal and heavier snows are beginning to move
water vapor from the oceans to the poles to re-build the polar ice caps and lead us into a global cooling, while man - made CO2 continues to increase http://www.colderside.com/faq.htm).
You can then
add in
water vapor and so on with my complete blessing, as long as you do not assert that gravity can do any net, continuous work even in the dynamic case in an atmosphere with a
more or less static density profile.
Later as the ocean warms to remove the leftover imbalance,
more water vapor is
added (which Lewis and Curry don't include in their calculation of ECS thus lowballing it).
In my opinion, these images clearly show that
adding more CO2 to the atmosphere is totally insignificant, mainly because the natural variation in
water vapor is so much larger than the amount of CO2
added by humans.
You are probably also aware already that
water vapor is as much if not
more of a so called greenhouse gas than carbon dioxide is and there is a lot of evaporating ocean
water on the planet not to mention clouds and high tropical humidity because hot air provides
added space in the atmosphere for
water vapor gas to become a major component of air.
Lindzens» idea requires reduced cirrus formation in the tropics, which in turn requires a reduction in
water vapor in the upper troposphere as heat is
added, the idea being that some sort of balance point is quickly reached where
more forcing from additional greenhouse gases will cease to have much of an effect.
32 Human Impact on Climate Change The Greenhouse Effect Is a natural warming of both Earth's lower atmosphere and surface Makes life as we know it possible Major Gases:
Water Vapor and Carbon Dioxide Humans have
added more greenhouse gases to the atmosphere in the past 200 years by burning fossil fuels
If the CO2 only eats red MM's while
water vapor eats all colors, once the total number of MM's is gone,
adding more of either gas will have no effect.
As I understand AGW, the theory goes that
added CO2 combines with an energy photon (ie the greenhouse effect) to warm the world, & heat the air which results in
more water vapor which absorbs
more photons which results in Man caused warming feedback.
Or put another way, if there is so much
water vapor around (3 % vs only 390ppm for CO2), and
more GHGs means
more warming, why does the GHE stop at 33C instead of continuing until all the
water vapor absorbs a photon OR asked another way, who says that all the
water vapor caused by the
added CO2 will absorb a photon to cause
more GHE warming?
Doesn't that then mean that there are no
more photons to be absorbed by the
added water vapor produced as a result of the
added heat from the CO2 associated warming?
As the temperature rises,
more water vapor enters the atmosphere and multiplies CO2's greenhouse effect; the Intergovernmental Panel on Climate Change notes that
water vapor may «approximately double the increase in the greenhouse effect due to the
added CO2 alone.»
Adding more Co2 will either increase this process slightly (the Walker circulation) or limit
water vapor's presence in the upper troposphere by radiational cooling.
