Global warming is an observed phenomenon.

The causes are being debated.
One camp says it's man made.
One camp says it's a natural phenomenon..
One camp says it natural but man is accelerating it.

The end effect is being debated.
One camp predicts terrible consequences.
One camp predicts changes, but not disastrous effects.

What we can do about it is being debated.
One camp says we must act decisively and swiftly to avoid disaster.
One camp says it's too late, the die is cast.
One camp says we can only affect the outcome slightly.

If you label any of the aforementioned camps, as conservative or liberal... you fail.
