The South Pole has warmed three times faster than the rest of the planet in the last 30 years due to warmer tropical ocean temperatures, new research showed Monday.<\/p>\n

Antarctica’s temperature varies widely according to season and region, and for years it had been thought that the South Pole had stayed cool even as the continent heated up. <\/p>\n

Researchers in New Zealand, Britain and the United States analyzed 60 years of weather station data and used computer modeling to show what was causing the accelerated warming.
\nThey found that warmer ocean temperatures in the western Pacific had over the decades lowered atmospheric pressure over the Weddell Sea in the southern Atlantic.
\nThis in turn had increased the flow of warm air directly over the South Pole\u2014warming it by more than 1.83C (about 3.3F) since 1989.
\nAuthors of the research said the natural warming trend was likely boosted by manmade greenhouse gas emissions and could be masking the heating effect of carbon pollution over the South Pole.
\n“While temperatures were known to be warming across West Antarctica and the Antarctic Peninsula during the 20th century, the South Pole was cooling,” said Kyle Clem, a researcher at Victoria University of Wellington, and lead study author.
\n“It was suspected that this part of Antarctica… might be immune to\/isolated from warming. We found this is not the case any more,” he told AFP.
\nThe data showed that the South Pole\u2014the most remote spot on Earth\u2014was now warming at a rate of around 0.6C (1.1F) a decade, compared with around 0.2C (1.4F) for the rest of the planet.
\nThe authors of the study, published in the Nature Climate Change<\/i> journal, attributed the change to a phenomenon known as the Interdecadal Pacific Oscillation (IPO).
\nThe IPO cycle lasts roughly 15-30 years, and alternates between a “positive” state\u2014in which the tropical Pacific is hotter and the northern Pacific is colder than average\u2014and a “negative” state where the temperature anomaly is reversed.
\nThe IPO flipped to a negative cycle at the start of the century, driving greater convection and more pressure extremes at high latitudes, leading to a strong flow of warmer air right over the South Pole.
\nClem said that the 1.83C (3.3F) level of warming exceeded 99.99 percent of all modeled 30-year warming trends.
\n“While the warming was just within the natural variability of climate models, it was highly likely human activity had contributed,” he said.<\/p>\n
