The rate of Arctic climate change was now faster than ecosystems and traditional Arctic societies could adapt to. WA-based scientists have warned of "dire consequences" to the human race after detecting the first signs of dangerous climate change in the Arctic.

The scientists, from the University of WA, claim the region is fast approaching a series of imminent "tipping points" which could trigger a domino effect of large-scale climate change across the entire planet. In a paper published in the Royal Swedish Academy of Sciences' journal AMBIO and Nature Climate Change, the lead author and director of UWA's Oceans Institute, Winthrop Professor Carlos Duarte, said the Arctic region contained arguably the greatest concentration of potential tipping elements for global climate change.

"If set in motion, they can generate profound climate change which places the Arctic not at the periphery but at the core of the Earth system," Professor Duarte said.  "There is evidence that these forces are starting to be set in motion."
