We continue to ignore the obvious.
It is wrapped in a single question
What will convince you that man made global warming is happening.
Until a denier puts forth the answer to this very simple question, there will continue to be debate on a question that the majority of the learned folk, those who have made themselves aware of the situation, have already made clear.
We are in the midst of yet another scientific question rendered political by those who's interests have made it so.
Answer the main question you just passed by, like science is just leap frog games..
SHOW ANY WARMING AT ALL that raises (pun) from the background of NORMAL.
You got shot down with that one, IPCC is failing you. Now you want to leapfrog with the word games.
First is was warming then, just change, First is was prove warming, Now, since there is no evidence at all, you gloss past that and pretend that step is done. No way is that proved
. Now you want to say, any change you prove is proof of man made.
So, the challenge to us, seems simple minded. You want us to give you ideas on how to prove man made climate change. HA Haaaa.
We say, if we see any change at all, it is normal climate cycles.
So, the question is base Sophistry, Mr Canndo.
No leapfrogs in Science. You don't have a foundation to use our ideas to help you goof about AGW.
You got no GW.
