My problem with this:
They say global warming is something we can't change, something we'll just "have to live with."
Isn't it a bit pessimistic and hypocritical to say we can have a negative effect, but not a positive one, on the climate? And furthermore, if global warming will continue with or without our input, how do we know it's our fault, and not just a climate shift that would have happened anyway?
Climate is a complex issue. I don't presume to be so arrogant to say that I could understand it, and I wonder, can anyone?
