Population: Is the World Ready for 7 Billion People?

Some time late in 2011—at least according to the people-crunchers at the U.N. Population Reference Bureau—humanity will reach a new demographic milestone with the birth of the 7th billion living person. (As a measure of just how fast global population is growing, the 6th billionth living person—Bosnian Adnan Nevic—is only 11.) You can expect the [...]

Weather: How the Troubled Response to the Blizzard Is Just the Beginning for a Warmer World

Yesterday afternoon, as we were closing this week’s issue of Time, I ended up in a debate with one of my editors over how the air travel system had responded to a December of terrible weather. I’d written a short piece coming out in the magazine describing the travel Armageddon the storm had created for [...]

Update: China Tainted Milk Activist Released?

The AP is reporting that Zhao Lianhai, the father arrested for protesting China’s tainted milk scandal after his son fell ill with kidney stones, may have been released on medical parole. If it’s true, however, it’s unclear what the conditions of his release are; his lawyer told the news wire that he had been unable [...]

Energy: Can We Run Out of Oil and Other Natural Resources?

Over at the New York Times, resident libertarian-contrarian John Tierney has a column about a bet he took in 2005 with the late energy analyst Matthew Simmons. Simmons—the author of Twilight in the Desert: The Coming Saudi Oil Shock and the World Economy—was a prominent believer in peak oil, the theory that we’ve reached the [...]

Politics: Celebrating the Passage of a Science Bill

For all the complaints about government gridlock, the 111th Congress proved to be incredibly productive, passing health care legislation, an unprecedented stimulus, major tax cuts, allowing gays in the military and vindicating a landmark arms control treaty. When President Obama addressed the press before Christmas, he celebrated those achievements, many of which came in the [...]

What Australia’s Floods Mean for the Great Barrier Reef

As New York shovels out of the snow and LA digs out of the mud, Australians are facing their own onslaught of extreme weather. The worst floods in half a century have hit the central and southern parts of Queensland, forcing at least 1000 residents to evacuate their homes with warnings that the worst may [...]

Global Warming: Farmers Will Need to Adapt to Changing Climates—But They’ve Done So in the Past

Of all the projected impacts of climate change, the scariest one in a world is the effect warming could have on our ability to feed ourselves. Scientists have looked at the impact of major heat waves in the past, and have found that such abnormally hot weather tends to hurt agriculture, with maize productivity levels [...]

Oil Spill: Providing Clean Energy for the Victims of Deepwater Horizon

Last week I wrote a column asking the question: whatever happened to the Gulf oil spill? Thanks to presidential commissions and great investigative reporting, we know a great deal about why the spill happened and what impact it might have on the land and the water of the Gulf. In the news, though, the spill [...]

Climate: The EPA Begins the Process of Regulating Greenhouse Gases

With the failure of carbon cap-and-trade legislation this year, and a passel of Republicans taking over the House who seem to doubt that global warming exists, Congress has become a dead-end for fighting greenhouse gas emissions. But the Supreme Court has given the Environmental Protection Agency (EPA) the power to regulate greenhouse gases as a [...]

Food: Why the Just Passed Food Safety Bill Is Only a First Step

The troubled but important food safety bill finally passed Congress yesterday, and should be signed by President Obama today. I have a post over at Healthland explaining why the bill may not be worth much without more funding.
