Un nuevo estudio dice que el cambio climático inducido por el hombre ha duplicado la superficie afectada por los incendios forestales en el oeste de Estados Unidos durante los últimos 30 años. Según el estudio, desde 1984, las temperaturas aumentadas y la aridez resultantes han provocado incendios que se extienden a través de un área adicional de 16.000 millas cuadradas, un área mayor que los estados de Massachusetts y Connecticut combinados

Climate Change Has Doubled Western U.S. Forest Fires
A new study says that human-induced climate change has doubled the area affected by forest fires in the U.S. West over the last 30 years. According to the study, since 1984 heightened temperatures and resulting aridity have caused fires to spread across an additional 16,000 square miles than they otherwise would have—an area larger than the states of Massachusetts and Connecticut combined. The authors warn that further warming will increase fire exponentially in coming decades.
Scotland to Generate Some of World's First Kite-Driven Power in 2017
The United Kingdom will begin harnessing energy from kites flying 450 meters above ground as early as next year. Developed by UK-based Kite Power Solutions, the system is composed of two 40-meter wide kites that rise and fall in tandem, spooling a tether line to turn a turbine.
Ferry de pasajeros con motor de hidrógeno en la bahÃa de San Francisco
Hace casi dos años, los investigadores Joe Pratt y Lennie Klebanoff de Laboratorios Nacionales de Sandia, se dispusieron a responder a una pregunta no tan simple: ¿Es factible construir y operar un ferry de pasajeros de alta velocidad únicamente propulsado con combustible de hidrógeno? La respuesta es sí.
Bees Are Declared Endangered for the First Time in the U.S.
For the first time in history, a group of bees in the U.S. will be protected under the Endangered Species Act, following a recent announcement from wildlife officials.
The group of bees, who are commonly known as yellow-faced bees because of the markings on their faces, are endemic only to the Hawaiian islands. While there are dozens of species, scientists identified several of them who are at risk of extinction and have been calling for their protection for years.
To Help Bees, Skip Herbicides and Pesticides, Keep Lawns Naturally Diverse
Declining populations of pollinators is a major concern to ecologists because bees, butterflies and other insects play a critical role in supporting healthy ecosystems. Now a new study from urban ecologists at the University of Massachusetts Amherst suggests that when urban and suburban lawns are left untreated with herbicides, they provide a diversity of “spontaneous” flowers such as dandelions and clover that offer nectar and pollen to bees and other pollinators.
