fluctuations in forcing
causing large changes
in temperature, a recipe for instability.
The
temperature of the troposphere is constantly being affected by variations
in the rate of energy flow from the oceans driven by internal ocean variability, possibly
caused by
temperature fluctuations along the horizontal route of the thermohaline circulation and by variations
in energy flow from the sun that affect the size (and thus density) of the atmosphere and the rate of energy loss to space.
Any expansion, or contraction

«We evaluate to what extent the
temperature rise
in the past 100 years was a trend or a natural
fluctuation and analyze 2249 worldwide monthly
temperature records from GISS (NASA) with the 100 - year period covering 1906 - 2005 and the two 50 - year periods from 1906 to 1955 and 1956 to 2005... The data document a strong urban heat island eff ect (UHI) and a warming with increasing station elevation... About a quarter of all the records for the 100 - year period show a fall
in temperatures... that the observed
temperature records are a combination of long - term correlated records with an additional trend, which is
caused for instance by anthropogenic CO2, the UHI or other forcings... As a result, the probabilities that the observed
temperature series are natural have values roughly between 40 % and 90 %, depending on the stations characteristics and the periods considered.»

The IPCC * itself * acknowledges that there has been no such warming now for the last 16 - 17 years; that no dramatic imminent change is seen to that for the next couple of years at least; that the previous spell of 15 years or so was precisely the duration of warming that underlay so much of the evidence cited for its alarms of the long and terrible global trend if forecast; that not a single model the IPCC had or has seems to have come even close to predicting what we've now seen; that the IPCC can only suggest possible explanations for all this so logically meaning it can have no reason to believe that whatever is
causing it isn't going to continue forever; that more and more studies are coming
in attributing global
temperatures not to CO2 but instead other things such as solar
fluctuations; that a number of predictions are now coming
in that

in for a lengthy period of * cooling.
