TEN ARGUMENTS EXAMINED - PART ONE

The BBC website has listed ten ARGUMENTS against the CO2 theory and then tried to counter them. Do their arguments add up? Over the next few days I am going to look at each one and evaluate it.

1. EVIDENCE THAT THE EARTH'S TEMPERATURE IS GETTING WARMER IS UNCLEAR
The BBC does not attempt to argue against two fundamental points;
one is that the surface temperature record is very incomplete, and the other is that attempts to reconstruct past temperatures using proxies, such as tree rings are not proven to be accurate. The fact that we have had warming of 0.4C in the last 40 years is not disputed.

2. IF THE AVERAGE TEMPERATURE WAS RISING, IT HAS NOW STOPPED
I would not argue that we know it has stopped. What is interesting though is why an El Nino event should raise the average global temperature. Surely the ocean movements can only move heat from one place to another?
