Those who think the political war on carbon will lower Earth’s temperature or keep climate stable need to study climate history.

Temperatures on Earth dance to a cyclic rhythm every hour, every day, every month, every season, every year, and to every beat of the sun-spot and glacial cycles.

The daily solar cycle causes continual changes in temperature for every spot on Earth. It produces the frosts at dawn, the mid-day heat and the cooling at sunset. It is regulated by rotation of the Earth.

Superimposed on the daily solar cycle is the monthly lunar cycle, driven by the orbit of the Moon around the Earth. These two cycles interact to produce variations in atmospheric pressure and tides, and currents in the oceans and the atmosphere. These are the daily weather makers.

The yearly seasonal cycle is caused as the tilted axis of Earth’s rotation affects the intensity of solar energy received by each hemisphere. This produces spring, summer, autumn and winter for every spot on Earth.

Then there is the 22 year sun-spot cycle, which correlates with cycles of floods and droughts. Sunspot

John Christy's testimony. More bad news for the Alarmists.


"When a theory contradicts the facts, you need to change the theory."


John Christy testified before the U.S. House Committee on Science, Space & Technology on  2 Feb 2016 (LINK -pdf)

Fig. 1: Five-year averaged values of annual mean (1979-2015) global bulk (termed
“midtropospheric” or “MT”) temperature as depicted by the average of 102 IPCC CMIP5
climate models (red), the average of 3 satellite datasets (green - UAH, RSS, NOAA)
and 4 balloon datasets (blue, NOAA, UKMet, RICH, RAOBCORE).


I shall begin with a discussion that was precipitated by an increasingly active campaign of negative assertions made against the observations, i.e. the data, of upper air temperatures. Figure 1 in particular has drawn considerable attention from those who view the climate system as undergoing a rapid, human-caused transformation into a climate to which people would have great difficulty adapting. This simple chart tells the story that the average model projection, on which their fears (or hopes?) are based, does poorly for the fundamental temperature metric that is allegedly the most responsive to extra greenhouse gases - the bulk atmospheric temperature of the layer from the surface to 50,000ft. 

As with all who show where the Warmists' greenhouse gas theory falls apart, John describes being
tossed into a world more closely associated with character assassination and
