Scientists have pieced together a 1200-year-long record of water availability, rainfall and drought across Europe, North Asia and North America.
The research, published today in the journal Nature, is the first time scientists have been able to accurately see how rainfall patterns have changed during the twentieth century compared with the last twelve centuries.
This contribution to the PAGES 2k Network, led by Fredrik Charpentier Ljungqvist, shows that climate models overestimate the increase in wet and dry extremes as temperatures increased during the twentieth century, and may have limited ability to realistically predict future hydroclimate changes under global warming.

A new study recently published in Quaternary Science Reviews takes a comprehensive look at the fall of Constantinople, and if climate change contributed to the collapse.
The paper, written by Elena Xoplaki et. al., is the product of a PAGES-supported meeting held in Greece in 2014. It examines ancient texts, excavated materials, lake sediments and climate models in an effort to understand what happened 800 years ago.
It was a prosperous time between AD 1081 to 1180 in the Byzantium society, but climate models show this period had less rainfall, overall warmer temperatures and colder winters. Scientists call this the “Medieval Climate Anomaly,” which was followed by a “Little Ice Age.”
In this blog article published today, PAGES' parent organization Future Earth takes an in-depth look at the QSR paper and current global instability.
