Is a green energy revolution on the global agenda?

A week after the most powerful “super typhoon” ever recorded pummeled the Philippines, killing thousands in a single province, and three weeks after the northern Chinese city of Harbin suffered a devastating “airpocalypse,” suffocating the city with coal-plant pollution, government leaders beware! Although individual events like these cannot be attributed with absolute certainty to increased fossil fuel use and climate change, they are the type of disasters that, scientists tell us, will become a pervasive part of life on a planet being transformed by the massive consumption of carbon-based fuels. If, as is now the case, governments across the planet back an extension of the carbon age and ever increasing reliance on “unconventional” fossil fuels like tar sands and shale gas, we should all expect trouble. In fact, we should expect mass upheavals leading to a green energy revolution.

Can Geoengineering Slow Climate Change?

The 1991 explosion of the Mount Pinatubo volcano in the Philippines. "Aerosoles in the stratosphere reduce the rate of climate change," says David Keith.

Interview by Johann Grolle

Canadian environmental scientist David Keith wants to change the world's climate by creating a type of sun filter in the sky to halt global warming. In an interview, he argues the technology is effective and inexpensive, but critics liken it to a nuclear bomb.

How Supercomputers Will Yield a Golden Age of Materials Science

The Materials Genome

The modern world is built on the success of materials science. The advent of transparent, conductive glass led to the touch screens on our smartphones. The reason those phones can beam information around the world at the speed of light is that materials scientists found a way to make glass free of impurity ions, enabling fiber-optic communications. And the reason those phones last a full day on a charge is because in the 1970s and 1980s, materials scientists developed novel lithium-storing oxide materials—the basis for the lithium-ion battery.

Just 90 companies caused two-thirds of man-made global warming emissions

The climate crisis of the 21st century has been caused largely by just 90 companies, which between them produced nearly two-thirds of the greenhouse gas emissions generated since the dawning of the industrial age, new research suggests.

U.S.-Israel Divergence Goes Beyond Obama, Netanyahu

Today the U.S.-Israeli relationship, long a bedrock alliance for both nations, is rancorous and tense. Americans on the political right attribute this to the weakness or even incompetence of President Barack Obama, particularly concerning Iran. Portraying the problem as one of personalities or political inclinations may keep pundits employed, but it misses the bigger and more important picture. The United States is, in fact, "pursuing a policy agenda in the Middle East that is increasingly divergent from Israeli interests," but this reflects more than just a predilection of the Obama administration. The divergence between the two old allies reflects deep changes in the way the United States sees its role in the world and a mounting sensitivity to the costs of national security. Because of this, the split between the United States and Israel is likely to grow.

Amsterdam's Plan to Pay Alcoholics in Beer is Just 'Dutch Pragmatism'

An unusual Dutch initiative aims to put an end to one of Amsterdam's worst nuisances -- those bawdy, loitering alcoholics -- by employing them in a kind of street cleaning corps. The problem, though, is that the state-financed Rainbow Foundation behind the project pays the self-professed chronic alcoholics in beer for their labor. 

Spy Copters, Lasers, and Break-In Teams help the FBI watch on foreign diplomats.

Between 2006 and 2009, surveillance helicopters conducted daily flights over northwest Washington, D.C., taking high-resolution photographs of the new Chinese Embassy being constructed on Van Ness Street. The aircraft belonged to the Federal Bureau of Investigation, which wanted to determine where the embassy's communications center was being located. But the Chinese construction crews hid their work on this part of the building by pulling tarpaulins over the site as it was being constructed.

Why Hezbollah Loves the U.S.-Iran Nuke Deal

BEIRUT -- American allies such as Israel and Saudi Arabia haven't been shy about criticizing the proposed deal over Iran's nuclear program. But one surprising party has come out in favor of a diplomatic solution: America's foe, the Lebanese paramilitary group Hezbollah.
