Global Warming: Fact or Fiction?

WRITTEN BY: Robert Woodard
Argentina's Esperanza Base on the northern tip of the Antarctic Peninsula: the hottest place in Antarctica.A new all-time temperature record for an entire continent is a rare event. But that may have happened for the continent of Antarctica last Tuesday for the second time in a week. As reported on the Weather Underground website, the mercury shot up to 63.5°F (17.5°C) at Argentina's Esperanza Base on the northern tip of the Antarctic Peninsula. The previous hottest temperature recorded in Antarctica was 63.3°F (17.4°C) set the day before at Argentina's Marambio Base, on a small islet just off the coast of the Antarctic Peninsula. Until then, the hottest known temperature in Antarctica was the 62.8°F (17.1°C) recorded at Esperanza Base on April 24, 1961.

The World Meteorological Organization (WMO) has not yet certified that this week's temperatures are all-time weather records for Antarctica, though the Argentinian weather service has verified that the temperatures measured at Esperanza Base and Marambio Base were the highest ever measured at each site.

The Antarctic Peninsula is one of the fastest warming spots on Earth. A 2012 Climate Central post by Michael Lemonick on documented how while the Earth as a whole warmed up by 1.3°F between 1900 and 2011, the Antarctic Peninsula warmed by 5°, forcing massive ice shelves to disintegrate and penguin colonies to collapse.

A 2012 study published in the journal Nature found that the recent warming is faster than 99.7% of any other given 100-year period in the last 2000 years.
