Someone Stop These Eco Idiots!!!

If the first 800 years of warming is not CO2 related, you can NOT possibly say that CO2 accounts for the other 5/6 ths - that is one hell of an amplification!

They aren't, they are saying it's likely. However we do see a direct correlation between the CO2 emitted by us and the temperature rise during the industrial revolution, without  any of the natural causes of temperature rise being present.

That is making facts fit theory again.

That’s misinterpreting the statement; again, they are not claiming to know for certain only pointing out the logical possibilities based on the research.

What caused the first 800 years of warming??? Where did the heat energy come from in the first 800 years that CO2 was not around to amplify? Where did the heat energy come from that the CO2 is allegedly amplifying after the 800 year period?

You’ve already been told...

It comes as no surprise that other factors besides CO2 affect climate. Changes in the amount of summer sunshine, due to changes in the Earth’s orbit around the sun that happen every 21,000 years, have long been known to affect the comings and goings of ice ages. Atlantic ocean circulation slowdowns are thought to warm Antarctica, also.

Solar activity etc, etc.

Actually there are many factors other than CO2 that can increase temperature, and the inevitable result is release of locked up CO2 after a lag.

How do we know the rate of change is bad?

Because human beings and other species will suffer the consequences sooner.

And we know we are to blame because the rise in temperature is in step with our CO2 emissions since the industrial revolution.

As I said previously - how do we know the rate of change we call "normal" is actually abnormally slow, and this "fast" rate of change is actually the true normal?

Because we have a historical record. Not just from ice cores, but from other sources.

Whether the rate the temperature is changing is the norm or not, we are to blame. If it was changing slowly, we would still be to blame if the temperature rise kept pace with our emissions.

We can look back into the earths history and see the same correlation between CO2 increase and temperature increase, as a result of 'natural' emissions' therefore, it doesn't take a genius to appreciate that if human beings now emit the same quantity of CO2 into the atmosphere, then the consequence will be global warming. We also have a reasonably good idea as to what the consequences will be, again, because we know the consequences of the natural release of CO2 in the earth’s early history.

It's a simple concept, as Magic Man pointed out, mankind is releasing all the carbon, that was locked up deep under ground in the form of coal and oil, it therefore makes perfect sense that we will experience the same, or similar temperatures to when that carbon was in the atmosphere previously in history, and we have a pretty good idea what that will mean.

We have been 'messing with it' since the industrial revolution.
