One of the best ways to debate climate science is to ignore if its happening and ask the real question - what is to be done.You could spend hours tossing data back and forth and both sides have a lot of pre-rehersed arguments. There are sites with every statement and a prerehearsed reply. The debate is a waste of time.Here is the reply to any climate change debator
"If you think climate change is occuring then by all means use any voluntary, non-forceful, cooperative, agoristic means at your disposal to fight it. Good luck with that."
Don't ever let someone mug you in their alley, mug them in yours.
