Abstract
The Cloud Reduction Global Warming, CRGW, theory is a cascading natural process that only since about 1970 has become significant in Climate Change. The basic elements of CRGW theory have been around forever, it is the size (% of the earth affected) that has increased to the point that this natural process can be seen. The CRGW theory starts on land with the concept of a Special Parcel, SP, that has been changed from its virgin state such that less water is evaporated than the original virgin land. (SP examples: UHIs, forest to crop, or surface mining) The lower water evaporation (as indicated by lower surface air specific humidity, SH) creates higher temp and lower relative humid, RH, than the original land. How much a SP has changed the evaporation is not known since the original evaporation is not known, but if the land surrounding the SP is unchanged it can be used as a reference (the zero) for how much the SP has changed. The changed vs virgin land difference in SH remains relatively constant as the size of the SP increases with time. The SP’s lower humidity hotter air rises in a plume about 2 to 4 time larger than the land area it came from to cloud level: thus, amplifying the cloud level effect. The cloud cover is related to the Vapor Pressure Deficit, VPD, (the difference between the saturated water vapor pressure and the actual water vapor pressure). Higher VPD less clouds. The less clouds more Sun (lower global albedo). More Sun more atmospheric enthalpy, higher temperatures, and more evaporation of water (SH rising). This cascading series of natural events increase with the size of the earth’s total SPs. Simply put: if less water is put into the atmosphere from land (relative to what was evaporated previously) the global cloud fraction will decrease, and it will get HOTter.
The atmosphere fingerprint supports the CRGW theory: Since 1970 temperatures, specific humidity, enthalpy, and VPD have been rising while relative humidity and cloud cover have been declining. The lower evapotranspiration, ET, (proportional to SH) in over 1500 cities has been confirmed by Mazroonei et al (8). The existence of Urban Heat Island plumes has been modeled and weather balloons have confirmed their existence.
Reasonable estimates of global SP ET (or SH) change in a mathematical models suggest that CRGW could be a significant contributor to global warming and is reversable.
