Geologic Column: By train or pipeline: That is the question

Transporting hazardous materials like oil on North America’s aging rail networks is risky. But pipelines are also risky. So what’s the best option, given that we must choose one?

Energy 360: Moving energy - No easy feat, but a vital conversation

Trucks, trains, planes and boats move food, clothing, cars, wood, steel, medical products, smartphones, bicycles, organic milk, free-range chickens—basically all consumer goods. And energy is no exception. Coal is mined and then carried to where it is burned. Oil and natural gas are moved from where they are produced to where they can be refined into transportation fuels and myriad other products, and then moved again. Uranium is mined and transported to create fuel rods for nuclear power plants or nuclear-powered ships.

Carbon and the city: Tracking emissions from megacities

Sometime in the first century A.D., Rome’s population passed 1 million. It took more than 18 centuries for a city to surpass the 10 million mark, which both New York City and Tokyo did by 1950. Just six decades later, the world now has about 20 such “megacities” with populations of 10 million or more, including the largest, Tokyo, with a population of 35 million.

Geologic Column: Saving the World? Or Just Saving Money?

It all started with a reporter.

I had just signed the American College and University Presidents’ Climate Commitment, which pledges that my university will try to decrease its carbon footprint and develop a plan to become carbon neutral, when a reporter from the local newspaper challenged my personal credentials, my knowledge of and commitment to the environment. Forget my background as an earth scientist, the many years I taught environmental geology, the summers I worked at a conservation-education camp. He wanted to know what kind of car I drove.

GSA meeting: Biofuels vs. food - developing countries suffer most

HOUSTON – Perhaps it’s because the Geological Society of America’s annual meeting is being held in conjunction with the Soil Science Society of America, the American Society of Agronomy and the Crop Science Society of America, or perhaps it’s because it has been a much-discussed topic this year, but biofuels are big at this meeting.
