Antarctica is warming overall

Some recent studies suggested how Antarctica isn't feeling the heat of global warming like the other continents but the latest study published in the journal Nature showed how Antarctica is overall warming, and not just the critical Antarctic Peninsula. Many scientists believed how warming only affects Antarctic Peninsula while other parts of the Antarctica are stable, or even cooling.

Overall, Antarctica is warming. Only eastern areas of continent have experienced cooling in the last 30 years.

However collected data that was gathered with the help of a complex model that combines weather station and satellite data showed that surface temperatures rose an average of 0.12 degrees Celsius per decade during the last half century, or about 0.5 degrees total. Western portions experienced the highest rate of warming, unlike the eastern areas that have experienced cooling trend in the last 50 years, but overall pictures hows that temperatures were still rising on average across the continent.

This is the first study that included area of West Antarctica as most of recent studies were oriented primarily on Antarctic Peninsula. This is mostly because Antarctic Peninsula is well equipped with lots of different weather stations collecting data, and analyzing it.
