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 blunt truth about the politics of climate change is that no country will want to sacrifice its economy in order to meet this challenge, ... But all economies know that the only sensible, long-term way to develop is to do it on a sustainable basis.

He is right. The storm should be a warning to President Bush about the consequences of his climate change policies.

Aviation is a rogue sector and its environmental impact is out of control. Climate change is the most urgent challenge facing humanity and yet aviation policy is doing the opposite of what is needed.

You couldn't necessarily say, 'That hurricane, that storm, that flood only happened because of climate change,' (but) you're starting to see a pattern of extreme weather events.
