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.

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 hours to fly.

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… read more

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…. read more

As Climate Stirs Arctic Sea Ice Faster, Pollution Tags Along

A warming climate is not just melting the Arctic’s sea ice; it is stirring the remaining ice faster, increasing the odds that ice-rafted pollution will foul a neighboring country’s waters, says a new study.

Christine McCarthy: A Cheerleader for the Physics of Ice

Christine McCarthy, a geophysicist at the Lamont-Doherty Earth Observatory, scrunches blocks of ice between hunks of rock to study how ice behaves under pressure. Her work provides an important piece of the puzzle of how glaciers move, what makes them speed up, and how they are contributing to sea level rise as the climate warms.

Could Climate Change Shut Down the Gulf Stream?

In the 2004 disaster movie “The Day After Tomorrow,”, global warming accelerated the melting of polar ice, disrupting circulation in the North Atlantic Ocean and triggering violent changes in the weather. Could climate change shut down the Gulf Stream?
