February in Europe was colder than in living memory with snowball fights in front of the Colosseum in Rome and people dying of exposure in Poland and several other countries.
In the high Arctic, winter ice hit record lows and temperatures were 30 to 40 degrees Celsius warmer than average for late February. Satellite images showed “a wedge of open water” north of the Norwegian archipelago of Svalbard and out into the Arctic Ocean.
“It’s just crazy, crazy stuff," said Mark Serreze, director of the National Snow and Ice Data Center in Boulder, Colorado, who has been studying the Arctic since 1982. "These heat waves – I’ve never seen anything like this.”
In 2004, the Arctic Climate Impact Assessment (ACIA) was released. Among its key findings, two ring especially true today: (1) “The Arctic climate is now warming rapidly and much larger changes are predicted,” and (2) “Arctic warming and its consequences have worldwide implications.”
Over the last few years, we have seen massive changes in the Arctic and it’s clear that these have worldwide implications. The only difference from 13 years ago is that the change is coming much faster than the ACIA predicted.
Besides altering the physical environment, climate change is changing the geopolitical calculus as well. A major sign of this is the recent release of China’s Arctic Policy, the first comprehensive official statement of the country’s Arctic perspective and intentions. The policy says there are two sides to the picture of Arctic change:
“On the one hand, melting ice in the Arctic has led to changes in the natural environment, or possibly can result in accelerated global warming, rising sea levels, increased extreme weather events, damaged biodiversity, and other global problems.” But, “[o]n the other, with the ice melted, conditions for the development of the Arctic may be gradually changed, offering opportunities for the commercial use of sea routes and development of resources in the region.”
Change in the Arctic is no longer just a matter for states in the region, the policy says. “It is an issue with global implications and international impacts.”
