High-Tech Maps of Tropical Forest Diversity Identify New Conservation Targets

and has no comments yet.
New remote sensing maps of the forest canopy in Peru test the strength of current forest protections and identify new regions for conservation effort, according to a report led by Carnegie’s Greg Asner published in Science.Asner and his Carnegie Airborne Observatory team used their signature technique, called airborne laser-guided imaging spectroscopy, to identify preservation targets by undertaking a new approach to study global ecology—one that links a forest’s variety of species to the strategies for survival and growth employed by canopy trees and other plants. Or, to put it in scientist-speak, their approach connects biodiversity and functional diversity.

Will more use of natural gas minimize or exacerbate climate change?

and has no comments yet.
Natural gas power plants produce substantial amounts of gases that lead to global warming. Replacing old coal-fired power plants with new natural gas plants could cause climate damage to increase over the next decades, unless their methane leakage rates are very low and the new power plants are very efficient.These are the principal findings of new research from Carnegie’s Ken Caldeira and Xiaochun Zhang, and Nathan Myhrvold of Intellectual Ventures that compares the temperature increases caused by different kinds of coal and natural gas power plants. Their work is published in Environmental Research Letters.
