IT IS BAD USE OF GOOD SCIENCE AND TOTALLY FAKE!

WE CAN'T DISPROVE GLOBAL WARMING BEING CAUSED BY CO2.

You can go back and forth like this for a very long time.
Here is what I know:
1. It is cold today.
2. It is raining today.
3. It was nice last week.
4. Al Gore is not a scientist.
5. It is pretty easy to accurately predict what the weather will be tomorrow.
6. It is a little more difficult to accurately predict the weather next week.
7. It is very difficult to accurately predict the weather in a month.
8. It is almost impossible to predict the weather in a year.
9. Global warming pundits try to predict the weather in a 100 years.
10. 50 (+/-) scientists agreed on the global warming statements from the UN.
11. 652 scientists said the UN analaysis was wrong.
12. Nobody discusses with much impact the differences between precise scientifc models and accurate ones.
13. Nobody seems to agree on the margin of error in climate predictions many, many years from now. Except to say that the margin of error is anyhwhere from 50% to 300%.
So--taking the position that it is a bunch of nonsense is ok.
and taking the position that it is a problem is ok too.
We do know that global warming is occuring--we don't know why.
We really don't know.
But one thing we DO KNOW is:
The North Pole and the South Pole on Mars are melting (
Mars Melt Hints at Solar, Not Human, Cause for Warming, Scientist Says)
This indicates that either 1) global warming is not caused by man or 2) global warming is caused by man and the two Mars rovers was all it took to "tip the scale" on Mars. Personally I go for number 1. It just seems more reasonable to me.
