COP15: Milankovic versus the Carbon Theorists

Almost all serious studies into climate change begin with words to the effect: 
"The Planet's eco- and climate systems are extremely complex". The more one 
reads, the more contradictory arguments one finds. In 1920, the Serbian 
geophysicist Milutin Milankovic was already presenting a plausible cosmic cause 
for temperature variation and climate change. So what is really at stake in 
Copenhagen, the need to save the planet or to serve the interests of the 
lobbies behind the "Carbon Theory"? 

Before El Niño and La Niña warped out of the Oceans and morphed into the Carbon 
Theory, it was not necessary to be a rocket scientist to understand that 
climate has changed over the years. The Ice Age came and went, wine-making used 
to be common in Northern England. 

This is where everybody agrees. An examination of the data over the last 
400,000 years indicates a direct correlation between temperature rises and 
increased natural emissions of CO2, with peaks and troughs occurring roughly 
every 50,000 years, the high and low Carbon Dioxide concentrations in ppmv 
corresponding directly to temperature rises and falls. If we accept the methods 
used to measure these fluctuations, there seems little room for doubt. 

Where the Carbon Theorists now step in, is the presentation of an alarming 
trend over the last decade, namely an exponential increase in Carbon DiOxide 
emissions accompanied by a corresponding spike in temperatures - the last 
decade has been the warmest on record. However, there was an enormous increase 
in CO2 levels 240,000 years ago, 130,000 years ago and 15,000 years ago. 

Milutin Milankovic (1879 - 1958) dedicated his scientific study to the effects 
of cosmic cycles, ocean currents and plate tectonics on climate change and his 
closer examination of the fact pointed towards the existence of changes in the 
cycle of the Earth's tilt every 41,000 years, which enabled him to predict 
changes in temperature (and climate) with remarkable accuracy. 

Other studies indicate a correlation between peaks in temperature and 11-year 
solar flare cycles and their corresponding knock-on effect on ocean currents 
and thermal flows; the effect of water vapour as being far more significant 
that CO2; the fact that the Arctic ice cap has melted before; the emissions of 
methane gases from animals being far more voluminous than human GEG. 

So Carbon emissions by humans are not the sole cause of climate change, since 
such fluctuations have occurred cyclically for hundreds of thousands of years 
and because there are other candidates to which to attribute the blame. 

Certainly, this does not mean that mankind is not polluting the planet and for 
sure does not negate the excellent work being done by the Green Parties and 
ecologists across the globe. However, is it not more dangerous to latch onto 
one supposed cause (which may be a factor but not THE factor behind climate 
change) than the many other causes with an equally valid weighting in the 
equation? 

If the world is coming together in Copenhagen to discuss global problems, then 
it would make sense to start with an approach which respects global issues 
equally and not concentrate too much on the points raised by the Carbon Theory 
lobbyists, without disrespecting the science that supports their point.
