(CNN) This week, an iceberg the size of Atlanta broke off a glacier. Researchers discovered a dramatic decline in Antarctic penguin colonies. And Antarctica may have just registered its hottest temperature ever.

In case all of that was not enough to make you at least a little concerned, yet another unusually high temperature was logged in the Antarctic Peninsula on February 9, when a weather station on Seymour Island produced a reading of almost 70 degrees. The World Meteorological Association is trying to verify it as a new record.

Though the WMO has not yet determined whether this reading breaks any sort of record, it certainly provides additional evidence of warming in the Antarctic region and around the world, according to Randall Cerveny, a meteorologist at Arizona State University and a climate extremes expert at the World Meteorological Organization.

According to the organization's website , these events are all consistent with trends seen in Antarctica over the past few years. The Antarctic Peninsula, where the potentially record-breaking February temperatures were logged, is one of the fastest-warming regions on the planet.

"Our polar regions are kind of the canary in the mine," said Cerveny, "They are a more sensitive environment, so they are a warning system to other areas of the world."
