Climate Change Dramatically Increases Rainfall in the Tropics
Posted by Laboratory Equipment: None Given on September 18th, 2012
Laboratory Equipment: Extreme precipitation in the tropics comes in many forms: thunderstorm complexes, flood-inducing monsoons and wide-sweeping cyclones like the recent Hurricane Isaac.
Global warming is expected to intensify extreme precipitation, but the rate at which it does so in the tropics has remained unclear. Now an MIT study has given an estimate based on model simulations and observations: with every 1 C rise in temperature, the study finds, tropical regions will see 10 percent heavier rainfall extremes,...

Laboratory Equipment: Ancient pollen and charcoal preserved in deeply buried sediments in Egypt's Nile Delta document the region's ancient droughts and fires, including a huge drought 4,200 years ago associated with the demise of Egypt's Old Kingdom, the era known as the pyramid-building time.
"Humans have a long history of having to deal with climate change," says Christopher Bernhardt, a researcher with the U.S. Geological Survey. "Along with other research, this study geologically reveals that the evolution of societies...
