We all know that the earth and all upon it face a growing crisis. Global climate change is rapidly advancing, melting glaciers, eroding soil, causing freak and increasingly wild storms, and displacing untold millions from rural communities to live in desperate poverty in peri-urban slums. Almost every human victim lives in the global South, in communities not responsible for greenhouse gas emissions. The atmosphere has already warmed up almost a full degree in the last several decades and a new Canadian study reports that we may be on course to add another 6 degrees Celsius (10.8 degrees Fahrenheit) by 2100.

A new study says the seas are acidifying ten times faster today than 55 million years ago when a mass extinction of marine species occurred. And, the study concludes, current changes in ocean chemistry due to the burning of fossil fuels may portend a new wave of die-offs. [...more]
The Earth has nine biophysical thresholds beyond which it cannot be pushed without disastrous consequences, the authors of a new paper in the journal Nature report. Ominously, these scientists say, we have already moved past three of these tipping points. [...more]
One way to maximize the eco-friendly factor of a structure is to include a green roof-and this doesn't refer to the paint color. "Greening" a roof, or covering a roof with vegetation, is gaining popularity in North America, where the number of green roofs increased 30% from 2006 to 2007. Benefits of green roofs include improved storm water management, energy conservation, reduced noise and air pollution, improved biodiversity, and even a better return on investment than traditional roofing.

Clearing the Amazon rainforest increases Brazilian communities' wealth and quality of life, but these improvements are short-lived, according to new research published today (12 June) in Science. The study, by an international team including researchers at the University of Cambridge and Imperial College London, shows that levels of development revert back to well below national average levels when the loggers and land clearers move on.

In the era of global warming, when many scientists say we are experiencing a human-caused mass extinction to rival the one that killed off the dinosaurs, one might think that the discovery of a host of new species would be cause for joy. Not entirely so, says Paul Ehrlich, co-author of an analysis of the 408 new mammalian species discovered since 1993. [...more]
Keeping tropical rain forests intact is a better way to combat climate change than replacing them with biofuel plantations, a study in the journal Conservation Biology finds. [...more]
The global economy is losing more money from the disappearance of forests than through the current banking crisis, according to an EU-commissioned study. [...more]
Large areas of forests could succumb to climate change; scientists urge local adaptation responses to avoid disaster for environment, forest-dependent people in new report [...more]
Devastating declines of amphibian species around the world are a sign of a biodiversity disaster larger than just frogs, salamanders and their ilk, according to researchers from the University of California, Berkeley. [...more]
