By burning fossil fuels for heating, electricity, transportation and other purposes, humans add CO2 to the atmosphere. Yet, by comparing ways in which the Earth’s temperature, CO2 concentration, sea level and ice sheets have changed in the past, we are able to learn valuable lessons about the climate system of today and tomorrow.

The Sustainable Development Goals, to be set by the United Nations in September 2015, will outline the international development priorities for the coming decades. What will the goals look like? How can we measure progress effectively? Where will the funding to implement these goals come from? Can an international climate agreement be reached in Paris next year, and what might it look like? Columbia’s Sustainability Media Lab will present “Road to 2015: A Pivotal Year for Sustainable Development,” a panel discussion, on Monday, Nov. 17.

President Obama addresses the 2014 UN Climate Summit.

President Obama this week announced a set of actions designed to help populations here and abroad develop better resilience against drought, sea level rise and other consequences of a changing climate. At The Earth Institute, the International Research Institute for Climate and Society has been working on these issues for years — making regular climate forecasts, insuring farmers against bad weather, and using data to better anticipate outbreaks of disease, manage water resources and improve forest management, among other programs.

It seemed to me unseemly for a scientist to be vocal on a political issue related, even indirectly, to his own research. Wouldn’t that be an indication of bias, of a lack of scientific impartiality? But I have changed my mind.
