Doesn't the chart say that periods of warming / cooling are normal? We just happen to live at a time of natural warming.
Right it is true that the earth does undergo periods of warming and cooling over vast periods of time. From what i have heard from Scientists though they say that the current rate of warming even if slow is just not in the same range as the earth natural warming and cooling cycles.

The Earth natural cycles happen over vast periods of time, the kind of warming we are seeing currently is happening much faster, even if it is still slow.

What i would like to know though is why do you believe that so many scientists (and there really is a large number from a large number of different countries) are misinforming everyone ? or do you just think they are all wrong ?

Also i take it you understand the main premise of man made global warming argument -

- that we can prove in test after test that air with a high C02 content heats up more when in it comes in contact with light, then air with a lower C02 content in fact significantly more,

- and secondly we can measure the levels of C02 in the atmosphere and show that they are increasing, and not only increasing but increasing at a rate that cant be explained by natural causes

- and finally it is a fact that we are burning more stuff then ever before which releases C02 into the atmosphere.

Do you believe any of these 3 statement to be false or dubious ?
