I could develop a theory that the world is cooling. If my theory includes evidence of the record lows recorded in parts of the world and adds that this will also lead to record highs in some areas then no matter what happens my ‘cooling world' theory has been proved. Such are the tactics of the ‘Global Warming' brigade.
There is little doubt that the world is warming, but to claim that 98% of scientists believe this is due to increased CO2 is untrue. The world has had periods with massively higher CO2 levels than today but with lower, similar and higher temperatures. Less than 1000 years ago it was warmer with much lower CO2. It is clear that current CO2 levels are increasing but no one really understands where this will lead.
Given that even the most rabid Warmers acknowledge that the overwhelming majority of CO2 production is natural, the real issue appears to be the loss of the earth's ability to reabsorb it. The most likely reason is the destruction of forests. The UN carbon credit scheme will do nothing to genuinely create greater CO2 absorption. It is a rort by an alliance of corporates and socialists. I would suggest this is what most people are concerned about.
