Odds of storm waters flooding Manhattan up 20-fold, new study finds Maximum water levels in New York harbor during major storms have risen by nearly two and a half feet since the mid-1800s, making the chances of water overtopping the Manhattan seawall now at least 20 times greater than they were 170 years ago, according to a new study.
Lava source may not be as deep as previously thought History is littered with evidence of events where vast lava outpourings originated deep in the Earth. However, new research at Michigan State University shows that the source of some of these epic outpourings, however, may not be as deep as once thought. The results, published in the Journal Geology, show that some of these lavas originated near the surface rather than deep within the mantle.
Are Large Dams Economical? A study of 245 large dams carried out at Oxford University shows that big hydropower is uneconomic. Actual costs are typically double pre-construction estimates - and have not improved over 70 years. Researchers at Oxford University have found that planners and policymakers systematically underestimate the costs and time required to implement large dam projects.

The Andes' pulsating rise New research by Carmala Garzione, Earth and Environmental Sciences professor from the University of Rochester suggests that the Antiplano plateau in the central Andes Mountains along with the entire mountain range likely arose in a series of periodic rapid pulses instead of a more continuous gradual surface uplift. According to Garzione, "In geologic terms, rapid means rising one kilometer or more over several millions of years, which is very impressive."
