"A Grande Seca": El Niño and Brazil’s First Rubber Boom. February 7, 2017.
People care about climate change when it affects them. That is why Pacific islanders fear rising sea levels more than the average American, and why many who live in coastal cities fear a projected increase in tropical cyclones more than those further inland. Yet the idea that an environmental change “over there” will not affect communities “here” makes little sense. More
Climate History Network Statement on U.S. Executive Order and Climate Policy. February 2, 2017.

Teaching Climate Change by Combining the Humanities and Sciences. January 3, 2017.
Most students at Brown University know Professor Kathleen Hess from the two-semester challenge of organic chemistry. But in a class that debuted this fall, “Exploration of the Chemistry of Renewable Energy,” Dr. Hess blended the tools of her discipline with questions of human impacts on the climate, renewable energy technologies, and the social impact of how energy is generated and used.

Volcanoes, Comet Crashes, and Changes in the Sun: How Cooling Transformed the World. December 3, 2016.
The world is warming, and it is warming fast. According to satellites and weather stations, Earth's average annual temperature will smash the instrumental record this year, likely by around 0.1° C. Last year, global temperatures broke the record by around the same amount. That may not seem impressive, but consider this: temperatures have climbed by about 0.1° C per decade since the 1980s. In just two years, therefore, our planet catapulted two decades into a hotter future. More
Towards a Messy History of Dearth and Climate in Carolingian Europe. November 14, 2016.
Will climate change trigger widespread food shortages and result in huge excess mortality in our future? Many historians have argued that it has before. Anomalous weather, abrupt climate change, and extreme dearth often work together in articles and books on early medieval demography, economy and environment. Few historians of early medieval Europe would now doubt that severe winters, droughts and other weather extremes led to harvest failures and, through those failures, food shortages and mortality events.

A Conversation with Bruce Campbell. October 31, 2016.
Bruce Campbell is a highly respected historian of medieval economic history. In his long and distinguished career at Queen's University, Belfast, he has belonged to the Departments of Geography, Economic History, History, and the School of Geography, Archaeology and Palaeoecology. Recently, he published a major new book: The Great Transition: Climate, Disease and Society in the Late-Medieval World. The book transforms how historians have understood the quintessential crisis of Western society - its apparent collapse in the fourteenth century - by rooting it in environmental forces. More
A Conversation with J. R. McNeill. September 30, 2016.
For the fourth episode of the Climate History Podcast, Dr. Dagomar Degroot interviews one of the world's leading environmental historians: Dr. John R. McNeill of Georgetown University. Professor McNeill has authored or co-authored six books, and edited or co-edited twelve. He is perhaps best known for Something New Under the Sun: An Environmental History of the Twentieth-Century World. More
What Made the Thule Move? Climate and Culture in the High Arctic. September 13, 2016.
In the year 1001 CE, Leif Erikson made landfall in Greenland, and traded with people who “in their purchases preferred red cloth; in exchange they had furs to give.” The Vikings called these people Skraelings. Present-day archeologists and historians call them the Thule. More
The “Dantean Anomaly” Project: Rapid Climate Change in Late Medieval Europe. August 27, 2016.
In the last years of his life, Dante Alighieri (1265-1321) was an unsuspecting witness to a rapid shift in climatic conditions that led to cooler and wetter weather all over the continent. Perhaps it was not by chance that in his Inferno, finished in 1314, the sinners guilty of gluttony and sent to the third circle of hell were punished by incessant cold rain, hail and snow, while squirming through foul-smelling mud that reminded contemporaries of the crops rotting on their fields.
