Antarctic peninsula likely to warm over next two decades

A new study by Dr. David Bromwich, Byrd Center researcher and head of the Polar Meteorology Research Group, shows that the Antarctic peninsula will likely experience increases in temperature and precipitation due to climate change.

An analysis of historic and projected simulations from 19 global climate models shows that, because of climate change, the temperature in the Antarctic peninsula will increase by 0.5 to 1.5 degrees Celsius by 2044.

The projections also showed that precipitation – a threat to ice if it manifests as rain – will likely increase on the peninsula by about 5% to 10% over that same time period.

The estimates were published recently in the journal Climate Dynamics.

“We are concerned about these findings. We’ve been seeing overall quite big changes on the peninsula, generally getting warmer and ice shelves and glaciers discharging into the ocean,” said David Bromwich, a leading author of the study and a research professor at The Ohio State University Byrd Polar and Climate Research Center and department of geography.

The peninsula sticks up like a tail off the northwest side of Antarctica, curving near the southernmost part of South America and Chile.
