Teleconference will attempt to explain huge snowstorms are due to global warming
The fact that there has in fact been no global warming is a mere bagatelle!
In an apparent bid to counter skepticism of the specious claim that global warming caused the string of heavy snowfalls in the US and Europe this winter, a media teleconference with "two leading climate and weather experts" has been scheduled for Tuesday, March 1, 2011. Mark "death spiral" Serreze and Jeff Masters will "discuss how a rise in the number of snowfalls of 6 inches or more may be related to an increase in moisture in the atmosphere," allegedly due to global warming.
Major problems with this argument include weather balloon and satellite data showing that 1) tropospheric relative and specific humidity has significantly declined since the 'safe CO2 levels' of 1948, 2) atmospheric water vapor has declined since satellite measurements began in 1983, 3) there has been no statistically significant global warming since 1995, and 4) the IPCC predicted milder winters and that the "milder winter temperatures will decrease heavy snowstorms."
Most climate models assume that as an increasing amount of atmospheric CO2 induces slightly increasing atmospheric temperatures, the overall evaporation will increase from the planet surface, and thereby the specific humidity of the lower part of the atmosphere (the Troposphere) will increase as well. As water vapour is the most important greenhouse gas, additional warming will come about, resulting in a much larger temperature increase than that induced from CO2 alone. Climate models therefore, in general, assume the relative Tropospheric humidity to remain more or less stable, as increasing air temperatures are compensated by increasing specific humidity.
The above diagrams indicate that none of this has been the case since 1948. Only near the planet surface, the relative humidity has remained roughly constant (although with variations), but in the remaining part of the Troposphere below the Tropopause the relative humidity has been decreasing. Even for the specific humidity, this appears to be the case.
