Now let us review the basic arguments against the global warming hypothesis. For the global warming hypothesis, namely that human-produced carbon dioxide is causing significant global warming, to be valid the alarmists must demonstrate that all of the following are true:
1. That temperatures today are at high levels compared to the last 5000 years and that significant global warming is occurring.
2. That carbon dioxide concentrations today are higher than the last 5000 years and longer, and that human-produced CO2 might cause global warming.
3. That the underlying physics of the so-called greenhouse effect is valid and doubling carbon dioxide concentrations will result in a temperature increase of at least about 4 degrees F.
4. That climate models can accurately predict future climate and the effect of doubling CO2.
In fact, none of the above four requirements is true. All are false and only one is needed to be false in order to negate the global warming hypothesis.
Another mini-science lesson is necessary here.
Question: Why is it necessary to follow the scientific method? Why can’t I just use my feelings? Can’t I conclude global warming is true even though the scientific method says otherwise? Maybe the scientific method is making a mistake this time.
Answer: The scientific method was developed over 2300 years ago by some really smart guys named Plato, Socrates and Aristotle. The method has proven itself over the last 2300 years to be the best way to arrive at the truth. If we throw it out, we do so at our peril. If we follow the scientific method, we will get the right answers. If we follow our feelings when they contradict the findings of the scientific method, then we will be wrong.
