There's no doubt that Arctic sea ice is melting at record rates, with rising temperatures in the region outpacing the global average increase, but a new article in Science questions whether there will ever be a tipping point in Arctic ice melting.Looking at the historical record, report author Dr Svend Funder says, quoted by BBC News:
I think we can say that with 50% of the current ice, the tipping wasn't reached. I don't say that our current worries are not justified, but I think that there are factors which will work to delay the action in relation to some of the models that have been in the media. I think the effect of temperature and global warming may cause a change in the general wind systems which maybe will delay the effects of the rapidly rising temperatures a little bit.
