    What the Vikings Can Teach Us About Adapting to Climate Change

    The rise of the Vikings was not a sudden event, but part of a long continuum of human development in the harsh conditions of northern Scandinavia. How did the Vikings make a living over the long term, and what might have influenced their brief florescence? Today, their experiences may provide a kind of object lesson…

    Climate May Quickly Drive Forest-Eating Beetles North, Says Study

    Over the next few decades, global warming-related rises in winter temperatures could significantly extend the range of the southern pine beetle, one of the world’s most aggressive tree-killing insects, through much of the northern United States and southern Canada, says a new study.

    Hannah Nissan: Forecasting Climate to Help Save Lives

    Hannah Nissan, a postdoctoral research scientist at the International Research Institute for Climate and Society, studies how better climate forecasting might help reduce the number of deaths from heat waves and improve agriculture and child nutrition.

    Eavesdropping on the Ocean’s Mighty Microorganisms

    Now, nearing the end of our three-week cruise of the North Pacific off Hawaii, we are working to understand how these tiny bacteria connect and communicate with one another.

    Surging Heat May Limit Aircraft Takeoffs Globally

    Rising temperatures due to global warming will make it harder for many aircraft around the world to take off in coming decades, says a new study. During the hottest parts of the day, 10 to 30 percent of fully loaded planes may have to remove some fuel, cargo or passengers, or else wait for cooler…

    Warming Climate Could Abruptly Increase Rain in Africa’s Sahel

    Climate change could turn one of Africa’s driest regions wet, according to a new study. Scientists have found evidence in computer simulations for a possible abrupt change in the Sahel, a region long characterized by aridity and political instability. In the study, just published in the journal Earth System Dynamics, the authors detected a self-amplifying…

    Fueled by Melting Glaciers, Algae Bloom Off Greenland

    Iron particles catching a ride on glacial meltwater washed out to sea are likely fueling a recently discovered summer algal bloom off the southern coast of Greenland, according to a new study. Microalgae, also known as phytoplankton, are plant-like marine microorganisms that form the base of the food web in many parts of the ocean.…
