Not 97% but .3% of Climatologists agree.

As I understand it, gwb's position is that the Earth is warming, but it's only because of a natural cycle, and that Man has nothing to do with it.

 

Very close. My actual position is that the earth is naturally warming since the 1970s. Soon the short term cycle will turn around and the earth will be cooling. Man has a very minor effect on the warming or cooling of the planet from a global perspective.

 

So what's causing the earth to naturally warm?

 

Good question. I was reading about orbital forcing and apparently we should be cooling now.

 

What has caused the earth to naturally warm and cool for thousands of years before mankind even showed up on the planet? Changes in axial tilt, sun cycles, and a host of factors. Better to spend research money on understanding these natural factors and not the fake AGW nonsense... and then spend further research money on how to adapt to natural these climate cycles.

 

What's causing CO2 to be 30% higher than it has been for hundreds of thousands of years?

 

As shown in many peer reviewed studies, CO2 leads global temperature by 800 years. The CO2 levels you are seeing now are reflective of the temperature at the end of the Medieval Warming period.

 

But the CO2 level we're seeing now is significantly unprecedented for a very long time. It's outside the bounds, why?

 

So it's initiated by changes in solar input right? Because all the other cosmological factors like axial tilt just serve to change solar input. Would you agree?

 

The CO2 levels we are seeing now are very much inside the bounds; well within two standard deviations of CO2 levels on earth over a long period of time.
