"Why I would rather be called a heretic on global warming"

You should read the entire article by UK environmental campaigner David Bellamy here.

One excerpt:

There is no escaping the fact that the concentration of carbon dioxide in the atmosphere has been rising for 150 years – and very uniformly since the 1950s. Yet the temperature has not increased in step with CO2. Not only have there been long periods of little change in temperature, but also the year-to-year oscillations are totally unrelated to CO2 change. What is more, the trend lines of glacial shortening and rise in sea level have shown no marked change since the big increase in the use of fossil fuels since 1950.

How can this be explained unless there are other factors at work overriding the greenhouse effect of CO2? There are, of course, many to be found in the peer-reviewed literature: solar cycles, cosmic rays, cloud control and those little rascals, such as El Niño and La Niña, all of which are played down or even ignored by the global-warming brigade.
