Climate change is crap.

Climate change is, in my view, long term, the single biggest issue that we face,

We're not going to negotiate some new treaty on climate change ... What this is about is seeing whether it will be possible in the future to bring people back into consensus together. Can we do that? I don't know, but it's important that we at least begin a process of dialogue that allows us to make progress on this.

The measurements show long-term trends. Glaciers react to climate change, and warmer temperatures in the Alps are reflected in the results.

If we let climate change run its course, this could be a fairly typical winter 30 or 40 years from now.

We're vulnerable to begin with, and climate change exacerbates the vulnerability.
