New Climate Study Indicates Hottest Decade in 1,300 Years

The new study uses a variety of evidence including ice cores, the result of painstaking data collection by NOAA and other research organizations. These data points provide a far more accurate picture than previous efforts derived from tree ring data. (Source: NOAA)

More research supporting a warming climate continues to pile on

Despite record lows in solar magnetic activity, thought to influence the climate, trends continue to point to a clear rise in temperatures worldwide. This is reflected by increased melting and other significant changes.

Now one of the more cohesive studies to date, published by Penn State's Earth System Science Center, has offered up a factual analysis of exactly how much warming is occurring. Rather than focus on creative modeling often considered a refuge of global warming skeptics and alarmists alike, Penn state instead analyzed historic and contemporary data.

It found that the last 10 years for the Northern Hemisphere were the hottest in 1,300 years. They also asserted that if more controversial tree ring data were used, this range could be extended to 1,700 years, but the tree ring data is for the first time unnecessary, eliminating much controversy.
