Francis 's research focuses on climate change in the Arctic , and has published over 40 scientific papers on the topic . It is also her opinion that warming in the Arctic may be changing the jet stream , which , in turn , may be leading to abnormal weather patterns such as an unusually long winter in the United Kingdom , the 2013 Colorado floods , and the unusually cold conditions across much of the southern United States in early 2014 . Specifically , Francis argues that the heating and cooling of Arctic seawater ( the Arctic is warming much faster than the rest of the world ) has slowed down the jet stream , resulting in weather conditions persisting for longer than they usually would . That the warming in the Arctic is linked to extreme weather elsewhere in the world is a view supported by some of Francis 's research , such as a study published in Geophysical Research Letters in 2012
