Most HS and College teachers do not allow Wiki as a source. Plus, the emails do not say “we must get rid of the Medieval Warm Period”.
Otherwise, a good example of what the article is claiming.
I was just reading “Eating in America,” a good book written apparently by Lefties (because of their constant “Indians were superior to Europeans” stuff). Nevertheless, they dedicate quite a bit of space to the appearance of warm-weather foods (including grapes) as far north as Greenland when the Vikings were sailing in the western Atlantic. Hmmm. Are they all gonna have to change, too?
What is "Global Warming"?
It is the theory that the mean temperature of the earth is increasing due to the greenhouse effect, caused by greenhouse gases such as CO2, which is produced by humans burning of fossil or carbon based fuels for energy. The solution to this is the reduction of the use of carbon based fuels.
OK, now that we agree on that, let's step through this.
1st, what is the "right" mean temperature of the earth?
Has it ever changed without man's influence?
2nd, the greenhouse effect in and of itself is not a bad thing, it is a good thing - we'd freeze to death at night or in the winter without it.
3rd, What is the most abundant, and also the most contributory "greenhouse gas"?
CO2?
No, it's water vapor, comprising 95% of the greenhouse effect. Man's contribution to the amount of water vapor is less than .001%, so we can ignore it.
Back to CO2. CO2 contributes around 3.6% to the greenhouse effect.
But what percentage of CO2 is natural and how much man-made? 97% of CO2 is naturally occurring, 3% due to man's actions.
This amounts to a 0.117% man-caused contribution to the greenhouse effect due to carbon emissions.
So, even if we ELIMINATED the use of carbon based fuels for energy production, thus destroying our lifestyle and civilization, we'd have less than a .117% effect on "global warming".
Now, I know that leftists are married to these "solutions" and will want to implement them anyway, regardless of their ineffectiveness. Now, can we discuss why? (topic for another post)
