Restoration of wetlands can reduce greenhouse gas emissions. This is shown in a report that has been written in part by researchers from the University of Gothenburg. Former wetlands that have been drained and which are currently used for forestry and agriculture give off 11.4 million tons of carbon dioxide equivalents. That can be compared with Sweden's total emissions of 57.6 million tons (when the land use sector is not included). But in Sweden's report to the Climate Convention, emissions from drained peatland are not visible since they are included with forest growth.

A new study suggests that increases in atmospheric CO2 could intensify extreme droughts in tropical and subtropical regions -- such as Australia, the southwest and central United States, and southern Amazonia -- at much a faster rate than previously anticipated, explains University of Texas at Austin professor Rong Fu in a commentary in the March 9 edition of Proceedings of the National Academy of Sciences.

What inspires people to support conservation? As concerns grow about the sustainability of our modern society, this question becomes more important. A new study by researchers at Cornell University provides one simple answer: bird watching and hunting.

This survey of conservation activity among rural landowners in Upstate New York considered a range of possible predictors such as gender, age, education, political ideology, and beliefs about the environment. All other factors being equal, bird watchers are about five times as likely, and hunters about four times as likely, as non-recreationists to engage in wildlife and habitat conservation. Both bird watchers and hunters were more likely than non-recreationists to enhance land for wildlife, donate to conservation organizations, and advocate for wildlife-all actions that significantly impact conservation success.

Perdimos una hora esta mañana, despertando ya a un cielo soleado. Algunos pueden sentir que les han robado una hora de su día. ¿Entonces, por qué tenemos el horario de verano?

Hasta cierto punto, es posible que tengamos que agradecer a Benjamín Franklin.

Franklin, quien escribió el proverbio "Temprano a la cama y levantarse temprano, hace a un hombre sano, rico y sabio", fue uno de los primeros en sugerir la idea. En un ensayo de 1784, escribió que el ajuste de los relojes en la primavera podría ser una buena manera de ahorrar en velas.

After 13 years of planning, the Solar Impulse SI2 took off last night from Al-Bateen Executive Airport in Abu Dhabi at 7:12 a.m. local time. This initiated the first leg of its historic attempt to be the first solar-powered airplane to fly around the world. If all goes well, the plane will return to Al-Bateen in June or July. As reported here in January, the first leg was a short 12-hour “shakedown cruise” to Muscat, Oman, piloted by Andre Borschberg. The plane landed safely in Muscat, more or less on schedule, at 12:14 p.m. Eastern time.

Of the two pilots who will take turns behind the wheel, Borschberg is the engineer and former fighter pilot who is intimately familiar with every detail of the plane’s design and construction.
