The mass
of frozen
water also
contributes to the global climate, which is changing as Earth's
temperature rises.
Rising Seas: Warmer ocean
water temperatures, the pumping
of ground
water, and melting
of the polar ice sheets have added
water to the oceans,
contributing to sea level rise.
The relative contribution
of each trace GHG to increased Eocene and Cretaceous land
temperatures at 4 × CO2, assessed with multiple separate coupled - ocean atmosphere HadCM3L model simulations, revealed methane and associated increases in stratospheric
water vapor dominate, with nitrous oxide and tropospheric ozone
contributing approximately equally to the remainder.
Re 9 wili — I know
of a paper suggesting, as I recall, that enhanced «backradiation» (downward radiation reaching the surface emitted by the air / clouds)
contributed more to Arctic amplification specifically in the cold part
of the year (just to be clear, backradiation should generally increase with any warming (aside from greenhouse feedbacks) and more so with a warming due to an increase in the greenhouse effect (including feedbacks like
water vapor and, if positive, clouds, though regional changes in
water vapor and clouds can go against the global trend); otherwise it was always my understanding that the albedo feedback was key (while sea ice decreases so far have been more a summer phenomenon (when it would be warmer to begin with), the heat capacity
of the sea prevents much
temperature response, but there is a greater build up
of heat from the albedo feedback, and this is released in the cold part
of the year when ice forms later or would have formed or would have been thicker; the seasonal effect
of reduced winter snow cover decreasing at those latitudes which still recieve sunlight in the winter would not be so delayed).
If C02 is the largest single
contributing factor to the Greenhouse Effect (because supposedly
water vapor is only involved as a feedback to primary chemistry involving C02 itself), and C02 lags
temperature increases (as has been stated on this very blog), how has the Earth ever returned to colder glacial conditions following periods
of warming?
Warmer
water contributes to hurricanes, well and good, but I never see mentioned what the effects
of the different air
temperatures and humidity from global warming are expected to have on hurricanes.
However, to support the assertion that global warming is responsible for a great deal
of damage from such events, it is sufficient to show that such events have the «signature»
of global warming — for example, that specific global warming - related factors such as abnormally high sea surface
temperatures, elevated
water vapor levels, and altered jet stream patterns
contributed to making Hurricane Sandy what it was — even if those factors can not be precisely quantified.
«As a coastal city located on the tip
of a peninsula, San Francisco is vulnerable to sea level rise, and human activities releasing greenhouse gases into the atmosphere cause increases in worldwide average
temperature, which
contribute to melting
of glaciers and thermal expansion
of ocean
water — resulting in rising sea levels,» the ordinance reads.
Because the new precise observations agree with existing assessments
of water vapor's impact, researchers are more confident than ever in model predictions that Earth's leading greenhouse gas will
contribute to a
temperature rise
of a few degrees by the end
of the century.
Changing concentrations
of CO2 will impact the
temperature and if it is an increase the positive feedback
of drawing out more
water vapor will
contribute to the average climate getting warmer.
Agricultural runoff, in combination with increased
water temperatures, has caused considerable non-point source pollution problems in recent years, with increased phosphorus and nitrogen loadings from farms
contributing to more frequent and prolonged occurrences
of anoxic «dead zones» and harmful, dense algae growth for long periods.
Algae blooms
of this type are totally natural and occurring repeatedly everywhere, surely they
contribute something to the slight localised increase in
water temperature.
The location
of Iceland with respect to the North Atlantic Drift, which carries warm
water from the tropics towards the poles, may also
contribute to the
temperature series being mismatched with records from Greenland or Scotland.
Since
water vapor
contributes 95 %
of the wrongly named «greenhouse effect» and since the increase in atmospheric carbon dioxide has a logarithmic and declining effect, the variation in
temperature at the surface must be vanishingly small.
AGW is a hypothesis that makes sense, namely: — GHGs absorb outgoing radiation, thereby
contributing to warming (GH theory)-- CO2 is a GHG (as is
water vapor plus some minor GHGs)-- CO2 concentrations have risen (mostly since measurements started in Mauna Loa in 1959)-- global
temperature has risen since 1850 (in ~ 30 - year warming cycles with ~ 30 - year cycles
of slight cooling in between)-- humans emit CO2 and other GHGs — ergo, human GHG emissions have very likely been a major contributor to higher GHG concentrations, very likely
contributing to the observed warming
«The dramatic changes in lake ice may also
contribute to further warming
of the entire region, because open
water on lakes
contributes to warmer air
temperatures, albeit to a lesser extent than open seawater,» Surdu said.
If all Joules
contribute equally, then each
of the 240 W / m ^ 2
of accumulated forcing must also
contributes 4.3 W / m ^ 2 to surface emissions adding up to over 1000 W / m ^ 2 corresponding to an average surface
temperature close to the boiling point
of water.
Since the ocean
temperature affects the air above the
water and movements
of air in the atmosphere
contribute to our weather, El Niño can influence weather patterns.

Enhanced CO2
contributes to plant growth in greenhouses as does the control
of fertilizer,
watering, humidity, and
temperature, which operators try to keep at optimum levels.
In the short run, our choices for what kind
of power plants we build can
contribute to freshwater supply stress — by committing an imbalanced share
of the available
water to power plant use — and can affect
water quality, by increasing
water temperatures to levels that harm local ecosystems, for example.
Rising atmospheric carbon dioxide not only
contributes to
temperature increase but, as some
of that carbon dioxide dissolves in the ocean, pH
of ocean
water declines.
One
of the most well - known effects
of global warming is an intensification
of the
water cycle, with higher air
temperatures leading to increased evaporation from the seas and soils, and more atmospheric
water vapor
contributing to more frequent heavy precipitation events.
«The corresponding reduction
of natural vegetation and
water bodies results in higher
temperatures in urban areas which may seem to be localized effect but in long - term it may
contribute to the global heat.»
Thus, the static stability
of the near - surface
water increases and the convective mixing
of cold surface
water with the relatively warm subsurface
water is reduced, thereby
contributing to the reduction
of sea surface
temperature in the Circumpolar Ocean.
