The dangerous effects of climate change are becoming increasingly apparent.

Climate policy is characterised by the habituation of low expectations and a culture of failure. There is an urgent need to understand global warming and the tipping points for dangerous impacts that we have already crossed as a sustainability emergency, that takes us beyond the politics of failure-inducing compromise. We are now in a race between climate tipping points and political tipping points.

The North Pole sea ice

There could be a brief time this summer when there is no ice on the North Pole, a US scientist Mark Serreze stated in June 2008, blaming global warming that has melted the Arctic ice sheet over decades.

"We could have no ice at the North Pole at the end of this summer" National Snow and Ice Data Centre scientist Mark Serreze said.

He put the chances of there being no ice at one point at 50 per cent, saying it could see "ships sail from Alaska to the North Pole, that's possible".

"Clearly if you look over what we have seen in the past three years and where we were headed, we are in ... this long-term decline and we may have no ice at all in the Arctic Ocean in summer by 2030 or so."[1]
