We don't have a lot more time to deal with climate change, ... We need the right balance between regulation and market-based approaches.

What we're seeing right now in global climate temperature is a signature of climate change. The large bulk of the scientific community say what we are seeing now is linked directly to greenhouse gases.

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.

The hurricanes we are seeing are indeed a direct result of climate change and it's no longer something we'll see in the future, it's happening now.
