Interview: America turns red, white and green

The US’s stance on climate change has shifted beyond recognition. President Barack Obama’s science adviser John Holdren tells Graham Lawton how the US will put its house in order, secure a deal at the make-or-break summit in Copenhagen, and lead the world’s fight against dangerous climate change

How will you persuade the American people that climate change is a problem and win support for policies to tackle it?

The polls show that 70 to 75 per cent of the American public accepts that climate change is real, that humans are largely responsible, and that we need to do something about it. But it doesn’t rank particularly high on their concerns: the top concern tends to be the economy. So it’s recognised as a problem but needs to move up.
