Also, the Arctic sea ice melt over the last two years was about 40 percent greater than the last forecast.
Professor England said that the observed rate of summer ice melt is now running faster than any climate model can predict.
"The Arctic sea ice was thought to be something we saw that we would continue to see during summer time right through to the end of this century, and possibly even beyond," he said.
"At the moment we may have an Arctic that is ice-free in summer as early as about 2030 and that really is bringing forward that ice melt much closer to now than we had previously thought," he added.
The scientists say that global warming could reach as high as 7 degree Celsius by the turn of the century if emissions are not curbed.
With that in mind, the scientists say that global emissions must peak, then decline rapidly within a decade if the worst of climate change is to be avoided.
