    Where Trees Meet Tundra, Decoding Signals of Climate Change

    In northern Alaska’s Brooks Range, the earth as most of us know it comes to an end. The northern tree line-a boundary that circles all of earth’s northern landmasses for more than 8,300 miles, and forms the planet’s biggest ecological transition zone–runs through here. Scientists from Columbia University’s Lamont-Doherty Earth Observatory are studying how climate…

    2015 Indonesia Fires Killed 100,000 People, Says Study

    In fall 2015, smoke from agricultural fires in Indonesia blanketed much of equatorial Asia. Schools and businesses closed, planes were grounded and tens of thousands of people sought treatment for respiratory illnesses. In a new study, researchers estimate that the smoke caused upward of 100,000 deaths across Indonesia, Malaysia, and Singapore.

    Drought and Fire Activity: What’s Climate Change Got to Do with It?

    Lamont-Doherty Earth Observatory scientist Park Williams, recipient of a Center for Climate and Life Fellowship, is investigating the influence of climate change on droughts and wildfires.

    Attributing Extreme Weather to Causes—Including Climate Change

    New research and more powerful computer models are advancing scientists’ ability to tease apart the forces that can worsen extreme weather. In a new report, a committee of the National Academy of Sciences that includes Columbia’s Adam Sobel assesses the young field of attribution studies.

    Peat Fires Choking Southeast Asia Pose a New Threat to Global Climate

    The Indonesian peat fires that have been choking cities across Southeast Asia with a yellow haze are creating more than a local menace—burning peat releases immense stores of CO2, contributing to global warming.

    As Los Angeles Heats Up, Fog Fades

    A new study has found that urbanization around coastal Southern California is driving fog away and causing the low clouds, crucial for providing shade and moderating temperatures in summer, to rise. This trend has important implications for ecosystems and cities.

  • What Do Wildfires Have to Do with Climate Change?

    What Do Wildfires Have to Do with Climate Change?

    “Climate change has been making the fire season in the United States longer and on average more intense,” said John Holdren, President Obama’s science advisor. And, wildfires are not only intensified by climate change, they also exacerbate it.

Recent record-breaking heat waves have affected communities across the world. The Extreme Heat Workshop will bring together researchers and practitioners to advance the state of knowledge, identify community needs, and develop a framework for evaluating risks with a focus on climate justice.
