Deep groundwater aquifers respond rapidly to climate variability

2/9/2017

UNIVERSITY PARK, Pa. — Changes in climate can rapidly impact even the deepest freshwater aquifers according to Penn State and Columbia University hydrologists.The researchers found that responses to climate variations can be detected in deep groundwater aquifers faster than expected — in many cases within a year.

Because rain water may take years to reach deep aquifers through natural infiltration, the findings suggest another factor is involved, such as pumping of aquifers done by agricultural industries.

Right after an asteroid killed the dinosaurs, life returned to the scene of the crime

12/13/2016

 Some 66 million years ago, a giant space rock smashed into the Gulf of Mexico and brought the age of the dinosaurs — along with 75 percent of all organisms on Earth — to an abrupt and fiery end. Tsunamis roiled the oceans, superhot shrapnel from the impact rained down from the skies, dust swirled into the atmosphere and blocked the sun, and minerals from the asteroid turned the surrounding water toxic.
