When I wrote a long story about the retreat of sea ice, I made clear it could go the other way for a while, and that doesn't mean we don't know that a warmer world will have less sea ice. It just means there's a lot of variability and people can pay too much attention to the big swings in one direction or the other.

We're an amazingly adaptive and resilient species. Once we put our mind to global warming, I have no doubt we'll figure a way through here that won't lead to utter calamity.

Every time someone reads a story about the politics poisoning the global warming stuff it makes it feel like a political story, meaning it's Us and Them, instead of what it is: this profound challenge we face given our energy norms right now, the fuels of convenience toward something new. No matter what the politics are, it's still an enormous transformation that has to take place.

I'm trying mostly to ask questions. And not just trying to stake out a position on something, but also trying to define the stuff we agree on. I'm having battles with comment posters trying to insert a little sense of order so it's not just a long pissing match between the edges, which is what I think a lot of the blogosphere is tending to do.

The aspects of global warming that matter most to people - how rapidly will the seas rise? Are hurricanes already getting stronger? How strong will they get as a result of warming? Those are still immersed in complexity. So in those realms that catch people's attention most, or that get used as symbols by environmental campaigners, those facets really do come with significant back-and-forthing.

There are still people who essentially live in intellectual silos and either read Mother Jones or watch Fox News, based on their worldview. And they pick information out that reinforces it rather than keeping an open mind.

The responsibility of the scientist or journalist is to convey the context. If you're talking about the Arctic Sea ice, you have to embrace the reality that there's a huge number of other things that influence that on a year-to-year basis.
