I think it should be said, scientific method does not prove anything, it can only disprove.
Thus anyone (politician, talking head, PhD, or Druid for that matter) claiming Climate change has been proven, I would view very critically, because it has not.
The American Physical Society as flipped-flopped over the years on what their official statement has been.. Here is some
a good rundown of the data so far:
"In the final analysis, the difference between CAGW alarmists and CAGW skeptics is that an alarmists believes the climate system has a gain of 1 and 11% positive feedback, while the skeptics believe that the climate system has a gain of about 1.4 and about 18% negative feedback."
So climate change is hardly "proven" - (but it has not been disproved!). So... what do do in the meantime? How bout we spend our time, money and energy to help balance things we know are out of balance, such as smog, polution and helping yourself and others live in more tune with Earth *gasp* locally?
Just a thought.
What do I think? I think climate change is a result of change in axial tilt, and had a divination that the magnetic field of Earth cycles (it has been proven already), and after so many cycles the Earth will give birth to another moon and look something like Mars in around 20,000 years, (And Mars will look like the Asteroid belt).
