Mr. Gifford Miller, a researcher at the University of Colorado, Boulder told Geography magazine: 'We have never witnessed the Arctic - especially the ice near Canada, warming up like that. This study shows that whether warming is due to natural changes or an increase in greenhouse gases in the atmosphere. "

This study also points to the important problem, the current Arctic temperature has exceeded the highest temperature mark ever in the early Holocene geological period about 11,700 years ago.

Miller and his colleagues measured Arctic temperatures by observing air bubbles trapped in the ice core in the region. Then combine them with the radioactive carbon from the moss from the ice cap melting on the island of Baffin, Canada.

Scientists conclude that the Arctic is heating up within about a century. Specifically, the warming of the Arctic began in 1970, but there was no sign of danger until the last 20 years.
