    What motivates people to accept or reject climate change? What do personal and political values have to do with it? How can you best get your message across? A new guide to climate change communication offers some of the answers.

  • Why are Past Surface Temperatures and CO2 Concentrations Important?

    Why are Past Surface Temperatures and CO2 Concentrations Important?

    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.

    Road to 2015: A Pivotal Year for Sustainable Development

    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…

  • The Greening of China

    The Greening of China

    China became the world’s largest carbon polluter in 2006, surpassing the U.S. But it is also rapidly going green through cutting coal use, investing heavily in renewable energy and launching the world’s largest carbon trading system.
