Heading North for the Arctic Winter. April 20, 2015.
By Benoit S. Lecavalier.
In early February, I had the opportunity to gather with fellow scientists in Longyearbyen, the most northerly permanent village in the world. The town is in the Norwegian Archipelago of Svalbard at approximately 80°N latitude, slightly over a 1,000 km from the North Pole. For that reason, it is the perfect place to explore the key issues currently facing the glaciological community. The most important: how do glaciers and large ice sheets respond to climate change, and affect global sea levels? This question can only be answered by unravelling complex relationships with potentially dire consequences for our civilization. More
Towards a Climate History of the Solar System. March 6, 2015.
Climate historians explore how climate change influenced human history. Until now, their research has investigated environmental changes on Earth, and with good reason. Many examine how climate change affected human beings in centuries when space travel could scarcely be imagined. Others are too concerned with contextualizing global warming to consider environments beyond Earth. However, recent breakthroughs in scientific understandings of Mars’s watery past suggest that climate history can, and should, expand into the Solar System. More
Climate Change Scepticism: Interdisciplinarity Gone Wrong? February 12, 2015.
This site explores interdisciplinary research into climate changes past, present, and future. Its articles express my conviction that diverse approaches, methodologies, and findings can yield the most accurate perspectives on complex problems. To contextualize modern warming, for example, we can reconstruct past climate change using models developed by computer scientists; tree rings or ice cores examined by climatologists; and documents interpreted by historians.

Is Arctic Sea Ice Recovering? January 10, 2015.
Last year might have been the hottest year ever recorded by our instruments. Average global temperatures were at least 0.27° C warmer than the average between 1981 and 2010, which was in turn up from the preindustrial norm. Overall, the past 17 years have been very warm, and since 2002 temperatures have been consistently well above the 1981-2010 average. However, that consistency is not clearly reflected in Arctic sea ice trends. In fact, the winter extent of Arctic sea ice has expanded in the last two years, seemingly defying projections of its imminent collapse. More
Climate, Crisis, and Causality in the Bronze Age. December 4, 2014.
In Europe, the “Bronze Age” lasted nearly 2,000 years, from approximately 3200 BCE to roughly 600 BCE. In this period, bronze tools were forged for the first time, revolutionizing how Europeans manipulated their world and competed for resources. The first trading networks connected the continent, as navigational knowledge reached heights that Europeans would not exceed until the fifteenth century. Centralized “palace economies” flourished throughout Europe and the Middle East, in ancient civilizations we remember today: on Minoan Crete, in Mycenaean Greece, in the Mesopotamian conquests of the Hittites and Akkadians, and of course in Egypt.
