New ice core research from the Antarctic Peninsula shows that the rapid warming of this region over the last 100 years has been unusual.
The research team, lead by Dr Robert Mulvaney OBE, from British Antarctic Survey (BAS) showed that a slower, natural warming event began in this region about 600 years ago followed by an accelerated warming over the last 100 years.
This is the first comprehensive reconstruction of a 15,000 year climate history from an ice core retrieved from James Ross Island in the Antarctic Peninsula region, according to the Eurekalert story.
This particular region on Earth has warmed nearly 2 degrees C. in the past 50 years, making the Antarctic Peninsula one of the fastest warming places on the planet.
The rapid warming in this region over the past 50-100 years coincides with present-day disintegration of ice shelves and glacier retreat, according to Dr. Mulvaney.

"This is a really interesting result. One of the key questions that scientists are attempting to answer is how much of the Earth's recently observed warming is due to natural climate variation and how much can be attributed to human activity since the industrial revolution."
"......if this rapid warming that we are now seeing continues, we can expect that ice shelves further south along the Peninsula that have been stable for thousands of years will also become vulnerable," says Co-Author Dr Nerilie Abram formerly from British Antarctic Survey and now with the Research School of Earth Sciences, at The Australian National University.

Climate change indicators continue to show the impacts from a warming world.
Despite the rapid warming trend and resulting loss of permafrost, methane levels along Alaska's Arctic slope have been fairly stable over the past 29 years.
This year could challenge 2012 for the lowest sea ice extent minimum in the satellite record for the Arctic region.
Large portions of northern North America have experienced a greening trend over the past three decades.
New research explains why the Southern ocean surrounding Antarctica has not warmed like the rest of the world's oceans.
The warming influence of carbon dioxide has increased by 50 percent above pre-industrial levels during the past 25 years, according to NOAA.
