Yes, global warming is part of a traceable natural cycle. What difference does that make? Human activities have shown signs of speeding up that cycle--not causing it. The problem is that this is a natural disaster on an unprecedented scale. Slowing it down may give people (and wildlife) just a bit more time to deal with it.
Some of the ways wildlife is coping is fascinating. Polar bears aren't going to survive this, but they have a 'plan'--they're hybridizing with the grizzly bears they were believed to have evolved from in the first place. These 'grolers' will be able to survive the warming as they lose their reflective fur coat, and are able to eat a wider variety of available foods. Since we now understand that natural hybridization is part of evolution, it's really a wonder to see it in action.
What gets me is that they are promoting the fiction that we can stop the global warming cycle. They're expecting us to forget what scientists already said when they first REALLY identified it--it's too late to stop it, if it was ever possible.
