We can look back through ice-core data and see over 800,000 years, relationships between carbon dioxide and the temperature of the world. So those people who deny the importance of climate change are just wasting their time. They're also being diversionary because if we don't act the risks are enormous.
Nicholas SternThe scientific evidence is now overwhelming: climate change presents very serious global risks, and it demands an urgent global response.
Nicholas SternThere is still time to avoid the worst impacts of climate change, if we take strong action now.
Nicholas SternAs an undergraduate, I did maths and physics. That doesn't make me a scientist. So I try to read and understand and talk to scientists.
