Down to Earth With: Glaciologist Richard Alley

If you don’t know who Richard Alley is, stop reading for a minute and search for him on YouTube. Go on, this can wait. Back? What you likely saw was Alley singing his rendition of Johnny Cash’s “Ring of Fire,” in which he explains subduction zones, or another similar song. In addition to being something of an Internet sensation for his energetic lectures and songs about geologic processes, Alley is a glaciologist who studies the effects of climate change.

Charting a course correction: A review of Earth: The Operators' Manual

"Earth: The Operators' Manual" achieves its goal, which is to prepare us to change course and relace fossil fuels with alternative sources to blunt the impacts of global warming.

Voices: Climate change and civil conflict: New clues from El Nino

In 2007, 11 retired admirals and generals from the U.S. armed forces published a report arguing that global climate changes represented a major threat to global security. That same year, U.N. Secretary-General Ban Ki-moon argued in a Washington Post op-ed that the ongoing Sudanese civil conflict was, in part, attributable to climatic changes. By combining new techniques from climate physics and econometrics, my colleagues and I have found evidence that there is some truth in these statements. Indeed, the global climate can influence the outbreak of civil wars.

A day without Glory

On a warm afternoon in early March, the Taurus XL rocket that was prepped for launch at Vandenberg Air Force Base in Southern California looked more like a giant chopstick standing on end than a potential game changer in the debate over climate change science. The barrel-shaped satellite that the rocket carried — named Glory — was designed to deliver critical information about small airborne particles called aerosols.

Endangered snow: how climate change threatens West Coast water supplies

If you turn the tap on in Seattle, the water flowing from the faucet likely originated as a clump of snow. In winter, snowflakes fall in the Cascades, accumulating in thick snowpack. The snowpack stores water in winter and slowly releases it in spring and summer as temperatures warm and snow melts. As snowmelt flows down the mountains, some of it is diverted and collected in reservoirs — destined to arrive in the homes of more than 1 million people.

Still in a haze: What we don't know about black carbon

Black carbon — fine particles of soot in the atmosphere produced from the burning of fossil fuels or biomass — has been known to be a health hazard for decades, a major contributor to the thick hazes of pollution hovering over cities around the world.

Reconsidering the economic implications of climate change

How much will it cost to implement plans to mitigate climate change? And if we don’t implement changes, what will the cost of climate change be?

Highlights of 2010: Definitive statements: a new trend?

“This is the way it was.” Or: “This is what is happening.” Hmmm. Scientists don’t usually make such definitive statements, given that in science, there are almost always caveats. Yet in the last year, such statements have been issued by several large groups of scientists who have come together to support a certain point of view. Are scientists feeling the need to dig in their heels because of public pressures? Or are we actually reaching some consensus?

Blogging on EARTH: Climate change threatens Virginia's vacation spots

Each year, millions of visitors flock to Virginia’s natural wonders, such as Shenandoah National Park, and to historical landmarks, like Jamestown, one of America’s earliest colonies. But a new report by the National Resources Defense Council (NRDC) states that many of Virginia’s landmarks are jeopardized by climate change.
