The balance of biodiversity within North American small-mammal communities is so out of whack from the last episode of global warming about 12,000 years ago that the current climate change could push them past a tipping point, with repercussions up and down the food chain, say Stanford biologists. The evidence lies in fossils spanning the […]

While Western countries are increasingly aware of the need to protect endangered species, the developing world’s appetite for raw materials is destroying vulnerable ecosystems, the report’s […]
WASHINGTON, DC, April 29, 2010 (ENS) – World leaders have failed to fulfill their commitments to reduce the global rate of biodiversity loss by 2010, and have instead overseen “alarming” biodiversity declines, finds the first assessment of how the targets expressed in the 2002 Convention on Biological Diversity have not been met. Since 1970, human […]

BY GWYNETH DICKEY New evidence gleaned by analyzing calcium embedded in Chinese limestone suggests that volcanoes, which spewed massive amounts of carbon dioxide into the atmosphere for a million years, caused the biggest mass extinction on Earth. In a paper published April 26 in the Proceedings of the National Academy of Sciences, a team of […]
By Jeremy Hance, www.mongabay.com April 22, 201 The biodiversity crisis, the climate crisis, the deforestation crisis: we are living in an age when environmental issues have moved from regional problems to global ones. A generation or two before ours and one might speak of saving the beauty of Northern California; conserving a single species—say the […]
