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…

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.

Understanding Today’s Climate Politics
The climate problem will be made less bad by technological, cultural, social and economic change that will force political change. Waiting for policy to be the change agent is an exercise in futility.

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.

Malaria Risk Increases in Ethiopian Highlands as Temperatures Climb
The highlands of Ethiopia are home to the majority of the country’s population, the cooler climate serving as a natural buffer against malaria transmission. New data now show that increasing temperatures over the past 35 years are eroding this buffer, allowing conditions more favorable for malaria to begin climbing into highland areas.
