Past climate change and the 2 °C Limit. October 11, 2014.
Last month, world leaders met at UN Headquarters in New York City for Climate Summit 2014. As protests raged across the globe, diplomats established the framework for a major agreement next year. The aim will be to limit anthropogenic warming to no more than 2 °C, a threshold established by scientists and policymakers, beyond which climate change is increasingly dangerous and unpredictable.

A scientific expedition to Southeast Greenland. September 9, 2014.
The Greenland ice sheet is melting fast, and it contains enough water to raise global sea levels by over seven meters if it were to disappear entirely. However, thousands of years ago the ice sheet was much larger, with a total of 12 metres ice-equivalent sea-level. There are many questions that remain unanswered about how Greenland lost all this ice from past to present. For example: how and where did the Greenland ice sheet lose mass? What climate history resulted in such a drastic change in the ice sheet? More
Understanding the culture of climate change. August 4, 2014.
Note: a reflection piece originally posted on The Otter.
Like the research that inspired it, this article is a cultural consequence of climate change. Seven years ago, I was on a bus, reading a book about ancient climates. I looked out the window at a sunset so brilliant, it seemed to ignite Toronto's skyscrapers. More
How climate scholars can shape climate policy. July 3, 2014.
In order to keep global warming below 2° C, there is desperate need for urgency in curbing greenhouse gas emissions. However, national and international policymakers have yet to take major action. In the most recent issue of Nature Climate Change, Cambridge University geographer David Christian Rose explains why even the governments that have publicly acknowledged the threat of climate change have been so slow to address it.

University loans vast archive relevant to climate history. May 25, 2014.
Many articles on this site outline the role of documentary evidence for testing, refining, and expanding reconstructions of past climates developed using scientific “proxy” sources and computer simulations. Documents that record past weather were written in literate societies. Hence, reconstructions of ancient climates cannot benefit from documentary refinement, and the same holds true for reconstructions of regions settled by non-literate societies. More
