The Arctic has warmed as much in the last decade as the rest of the planet has in 137 years.
With 2019 set to be one of the warmest years on record, scientists found that the Arctic has warmed by 0.75 C in the last 10 years alone.
The Earth as a whole has warmed by 0.8C over the past 137 years, findings published in the journal Science Advances reveal.
Study co-author Professor Michael Mann, of America’s Penn State University, added: “What happens in the Arctic doesn’t stay in the Arctic.”
He said the impact of the sea level rises resulting from rapid melting of land ice would reach beyond the polar regions.
This would increase risk deadly heat waves and wildfires in the Northern Hemisphere.
They said reducing carbon emissions was “crucial” to slowing the warming process.
Earlier this year other research revealed that global temperatures soared to 1.1°C above levels seen before the industrial revolution .
The World Meteorological Organisation has highlighted some of the impacts of rising temperatures in 2019, and is appealing for urgent climate action.
Mr Antonio Guterres, UN Secretary-General, said: “The last five years have been the hottest ever recorded. The consequences are already making themselves felt in the form of more extreme weather events and associated disasters, from hurricanes to drought to floods to wildfires.
"Ice caps are melting. In Greenland alone, 179 billion tonnes of ice melted in July. Permafrost in the Arctic is thawing 70 years ahead of projections. Antarctica is melting three times as fast as a decade ago.
"Ocean levels are rising quicker than expected, putting some of our biggest and most economically important cities at risk."
