Human-caused warming likely led to recent streak of record-breaking temperatures

Dr. Michael Mann and others have published a paper in Geophysical Research Letters stating that it is "extremely unlikely" that 2014, 2015, and 2016 would not have been the warmest consecutive years on record without anthropogenic climate change.

Figure from paper showing normal and extreme jet stream Extreme weather events linked to climate change impact on the jet stream

Dr. Michael Mann and others have published a study in Nature Scientific Reports looking at increasing frequency of extreme weather events and the connection to climate change through changes in the jet stream. Through a combination of observations and model output, researchers were able to identify specific events that were linked to stationary peaks in the waves of the jet stream.

Global climate models do not easily downscale for regional predictions

Dr. Fuqing Zhang, professor of meteorology and director of the Center for Advanced Data Assimilation and Predictablity Techniques at Penn State, and Dr. Mann, director of the ESSC at Penn State, conducted research on global climate models after expressing concern that the use of these models on a regional scale could produce inaccurage information.

Odds are overwhelming that record heat due to climate change

ESSC director Dr. Michael E. Mann and others have recently published a study in Nature Scientific Reports showing that the recent record-breaking warm temperatures would have been extremely unlikely without human-caused climate change.

NYC risks future flooding during hurricanes

Mann Research Group graduate student Andra Reed has a new article in the Proceedings of the National Acadamies of Sciences about the impact of climate change on coastal flooding due the combined effect of storm surges from stronger hurricanes and sea level rise. Dr. Michael Mann was a co-author on the paper.
