Lead author, Dr Michael Singer from School of Earth and Ocean Sciences at Cardiff University, said: «In drylands, convective (or short, intense) rainfall controls water supply, flood risk and soil moisture but we have had little information on how atmospheric warming will affect the characteristics of such rainstorms, given the limited moisture in these areas.»
--- ignorance about atmospheric chemistry really shows here...... snip --- «Moreover, the CO2 that is supposedly causing «catastrophic» warming represents only 0.00035 of all the gases in the atmosphere (1.25 inches out of a 100 - yard football field), and proposals to control this vital plant nutrient ignore a far more critical greenhouse gas: water vapor.»
He was also interested in controlling environmental damage, but he was mostly thinking about atmospheric and water pollution by power plants and strip mining — including effects of acid rain.
Yet atmospheric water is one of the most important greenhouse gases controlling the radiation and heat balance of the earth, Dr. Parkinson said.
Here are just some of the many benefits that these systems provide all at once: green infrastructure absorbs and sequesters atmospheric carbon dioxide (C02); filters air and water pollutants; stabilizes soil to prevent or reduce erosion; provides wildlife habitat; decreases solar heat gain; lowers the public cost of stormwater management infrastructure and provides flood control; and reduces energy usage through passive heating and cooling.
Within about two - weeks time, the atmospheric water vapor distribution had essentially returned back to control run levels.
The big unrecognized sleeper in ozone control is atmospheric water vapour.
The oceans are the main control of atmospheric CO2 as one of the atmospheric gases in constant flux between the water and the atmosphere.
Humans have no direct control over atmospheric concentrations of water vapour, although it can act as an enhancer for any global warming.
Based on the understanding of both the physical processes that control key climate feedbacks (see Section 8.6.3), and also the origin of inter-model differences in the simulation of feedbacks (see Section 8.6.2), the following climate characteristics appear to be particularly important: (i) for the water vapour and lapse rate feedbacks, the response of upper - tropospheric RH and lapse rate to interannual or decadal changes in climate; (ii) for cloud feedbacks, the response of boundary - layer clouds and anvil clouds to a change in surface or atmospheric conditions and the change in cloud radiative properties associated with a change in extratropical synoptic weather systems; (iii) for snow albedo feedbacks, the relationship between surface air temperature and snow melt over northern land areas during spring and (iv) for sea ice feedbacks, the simulation of sea ice thickness.
The basic results of this climate model analysis are that: (1) it is increase in atmospheric CO2 (and the other minor non-condensing greenhouse gases) that control the greenhouse warming of the climate system; (2) water vapor and clouds are feedback effects that magnify the strength of the greenhouse effect due to the non-condensing greenhouse gases by about a factor of three; (3) the large heat capacity of the ocean and the rate of heat transport into the ocean sets the time scale for the climate system to approach energy balance equilibrium.
Steven, doesn't that calculation require that you ignore the Milankovich effect on global temperature fluctuations on 10 ^ 4 years timescale (i.e. on the development of glacial maxima and interglacials) and the well - established long - term (c. 10 ^ 3 years) control of atmospheric CO2 level by ocean water temperature?
Isn't it obvious that the atmospheric water cycle (ground state water - > evaporation - > water vapor - > clouds - > precipitation - > ground state water) is the thermostat controlling the planet's energy balance and ultimately the surface temperature?
