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.

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.

It is time that President Bush undertakes a radical review of the proper position on climate change and the consequences of the energy policy of the United States.

Understanding climate change and its consequences is critical to protect lives and assets upon which India's economy is dependent.
