Arctic report card: Update for 2010
The Arctic Report Card tracks recent environmental changes throughout the Arctic, and is updated annually. In 2010, it is clear that the Arctic is experiencing the impacts of a prolonged and amplified warming trend, highlighted with many record-setting events. Not surprisingly, the impact of this warming is most evident in the dramatic losses that have been observed in the ice covers that define the region. Since the loss of these ice covers serves to further feed the warming trend, the expectation is that warming will continue. This makes it increasingly unlikely (at least for the foreseeable future) that the Arctic will return to conditions that were considered normal in the later part of the 20th century. Instead, it is very likely that Arctic climate warming will continue and we will continue to see records set in years to come.
