David Cameron Ready For Change, Full Conservative Conference Speech

The dangers of climate change are stark and very real. If we don't act now, and act quickly, we could face disaster.

Yes, we need to change the way we live. But is that such a bad thing? The insatiable consumption and materialism of the past decade, has it made us happier or more fulfilled?

Yes, we have to put our faith in technologies. But that is not a giant leap. Just around the corner are new green technologies, unimaginable a decade ago, that can change the way we live, travel, work.

And yes, we need global co-operation. But that shouldn't be difficult. It just takes leadership, and that's what we need at the Copenhagen summit this December.
