After a series of embarrassing predictions and wild factual errors damaged global-warming alarmists’ credibility — possibly beyond repair — the United Nations is again warning of impending doom: localized floods and droughts caused by climate change theoretically linked to human activity. But skeptics are still not buying.

To celebrate America Recycles Day, the Tellus Institute published a study showing the benefits of increased recycling, by force if necessary. The Tellus Institute’s mission is “to advance the transition to a sustainable, equitable, and humane global civilization,” and has published 3,500 studies, analyses, and reports on everything from energy, water, sustainable communities, corporate social responsibility, and climate change.

United Nations Secretary General Ban Ki-moon (left) called on world leaders Monday to collaborate in financing a multibillion-dollar fund to combat global warming. Speaking at a conference in Bangladesh’s capital, Mr. Ban said global efforts must be taken to establish a $100 billion Green Climate Fund dedicated to taming the "damaging" effects of climate change, and that the global economic crisis should not hinder such efforts.

TransCanada’s much anticipated Keystone XL oil pipeline will endure further delay as the State Department announced Thursday a plan to reroute the pipeline away from certain areas that critics claim are "environmentally sensitive."

The recent release of the Berkeley Earth Surface Temperature (BEST) study, which showed a worldwide temperature increase of about 1°C since 1950, was heralded by many as proof of global warming. Some skeptics, however, noted that the BEST data also showed that temperatures had remained unchanged for the past decade, suggesting that any warming trend had ended around the turn of the century.
