For six centuries, the ancient Maya flourished, with more than a hundred city-states scattered across what is now southern Mexico and northern Central America. Then, in A.D. 695, the collapse of several cities in present day Guatemala marked the start of the Classic Maya’s slow decline. Prolonged drought is thought to have played a role, but a study published this week in the journal Geophysical Research Letters adds a new twist: The Maya may have made the droughts worse by clearing away forests for cities and crops, making a naturally drying climate drier.

Daehyun Kim, a climate scientist at Lamont-Doherty Earth Observatory, has been recognized for early-career achievement in the atmospheric sciences by the American Geophysical Union, the world’s largest earth-sciences organization. Kim, 32, came to Lamont as a postdoctoral researcher in 2010, where he has focused on investigating the Madden-Julian Oscillation, a little-understood weather pattern that typically forms in the Indian Ocean and brings heavy rains and hurricanes to many parts of the globe.

In an effort to understand how plants around the world will act in a warming climate, researchers have relied increasingly on experiments that measure how they respond to artificial warming. But a new study says that such experiments are underestimating potential advances in the timing of flowering and leafing four to eightfold, when compared with natural observations. As a result, species could change far more quickly than the experiments suggest, with major implications for water supplies, pollination of crops and ecosystems. The comparison, done by an interdisciplinary team from some 20 institutions in North America and Europe, appears this week in the leading journal Nature.
