  • Climate Change Could Drive Vast Human Migrations

    Displacements Already Underway, Says Report

  • Adaptive Strategies in Managing Climate Change Risk

    With the threat of rising sea level due to thermal expansion (water increases volume as it gets warmer) and melting of land-based ice (such as glaciers and polar ice sheets), coastal cities are planning ways to minimize the impacts of flooding on city infrastructure. The Thames Barrier (pictured) is one such engineering solution. It is…

    Be sure to check out the launch of Climate Change: Picturing the Science, to be hosted by the Columbia Climate Center tomorrow. The book, which the Earth Institute’s Kevin Krajick blogged about recently, features essays addressing the different aspects of climate change alongside stunning climate-related photographs. Here are the event details: Columbia Climate Center: Book…

  • Picturing Climate Change

    Intense public interest in changing climate has led to a wave of books. Among the entries,  one upcoming standout is Climate Change: Picturing the Science, from W.W. Norton in April. The book is a  journey around the globe via essays and images from top-flight scientists and photographers. The visuals and narration range from field research in remote polar regions to the giant gates now being erected in European…
