The Global Cooling Event of the Sixth Century. Mystery No Longer?

Dr. Tim Newfield, Princeton University. 

The June 1991 Pinatubo eruption in the Philippines was one of the largest volcanic eruptions of the twentieth century. It is well documented. There are living witnesses, newspaper articles, detailed surveys of the mountain before and after it blew its top, and satellite maps of the ejecta. The eruption was photographed from the ground and the air, and today you can even YouTube it. Pinatubo released up to 20 megatons of sulphur dioxide as many as 35 kilometers into the sky. It turned into fine sulphuric acid aerosol, and, within weeks, enveloped much of the Earth. The aerosols were suspended in the atmosphere for around two years. While there, they "veiled" the sun by absorbing or "backscattering" solar radiation. That heated the stratosphere but cooled Earth's surface. Read more

NASA’s Role in Climate History

The National Aeronautics and Space Administration (NASA) was created in 1958. The agency’s initial purpose was to develop aerospace technologies that would help the U.S. compete with the Soviet Union in the Space Race. However, NASA’s programs soon expanded into other areas. As the agency’s programs evolved in the latter half of the twentieth century, NASA became more involved in Earth Sciences. In 1984 Congress revised the Space Act to be more inclusive of research on Earth’s climate. Today NASA satellites play an important role in collecting data that scientist use to study climate change. A brief article on NASA’s website explores the agency’s initial expansion into Earth Sciences and its growing role in providing the technological means to document changes in the Earth's climate.

Contextualizing Western Drought

Dr. Ruth Morgan, National Centre for Australian Studies, Monash University

At the 2016 American Society of Environmental History conference in Seattle, I joined Linda Nash(University of Washington), Char Miller (Pomona College), and Libby Robin (The Australian National University) to contextualize Western drought in environmental, historical and cultural terms. ‘Western drought’ in this instance referred to the region that the US Drought Monitor classifies as ‘West’, where some areas are still experiencing ‘exceptional’ drought conditions. Our discussion drew this Western experience into transnational conversation with histories of drought in Australia, further west across the Pacific. By providing a humanistic perspective of drought, the lens of environmental history complements the scientific study of climate conditions and offers valuable insights into how droughts have been understood and experienced over time.

Climate Change and History Initiative Workshop

The Climate Change and History Research Initiative (CCHRI) of Princeton University is holding a workshop on palaeoclimatology and palynology from September 12 to 14, 2016. This workshop is geared towards younger scholars, such as junior faculty members and graduate students, from the humanities and social sciences. The focus of the workshop is on the reconstruction of past climates using natural archives such as sediments. Neil Roberts, of Plymouth University, and Warren Eastwood, of the University of Birmingham, will lead the workshop. Those interested should submit a statement of interest (up to 500 words), a CV, and a letter of recommendation to Jayne Bialkowski (jayne@princeton.edu) with the subject line titled“Application for Palynology Workshop.” The deadline is June 1, 2016 and successful applicants will be notified in early July.

CHN Spring Newsletter Published

Nicholas Cunigan, our newsletter editor, has just published the Winter 2016 issue of our quarterly Climate History Newsletter. This issue contains some good news from our founders, an article that weighs the case for anthropogenic climate change that long predates industrialization, and an extensive list of recent publications in climate history.

CHN Lunch on March 31 in Seattle

We are organizing an informal climate history lunch for next week's American Society for Environmental History conference in Seattle. We will meet on Thursday at 11:30 at Icon Grill, which is just a three-minute walk from the Westin Seattle. This will be a good chance to chat about some of our accomplishments over the past year, and to plan the future of our network and discipline.
