Climate: Stop Global Warming with a New Computer Game

The world’s politicians have, so far, done a perfectly crap job of dealing with climate change. The bold promises of the 1992 Earth Summit in Rio de Janeiro, which led to the creation of the United Nations Framework Convention on Climate Change (UNFCCC), have yet to be fulfilled. Kyoto Protocol or no Kyoto Protocol, global carbon …

Vacationing in Space? The Planet Could Pay

To hear Richard Branson tell it, your next vacation will be in space. On Friday, Branson, the swashbuckling CEO of Virgin Airlines and the newer Virgin Galactic, cut the ribbon on a 2-mi. (3.2 km) runway in La Cruces, N.M., which will be used in as little as 18 months, he promises, to begin carrying paying tourists into suborbital …

Climate: Why CO2 Is the “Control Knob” for Global Climate Change

Not to use an overly technical term here, but there’s a neat paper in this week’s Science that explains clearly why carbon dioxide (CO2) is the main agent behind changes in the Earth’s climate—now and in the geologic past. First a bit of background: one argument you might hear from skeptics of manmade climate change is that CO2 is much …

Is the Arctic Headed for Another Cold War?

Arctic security wonks are gathering in Cambridge this week for a workshop on the challenges ahead for environmental security in the Arctic. Sound familiar? It should: When Russia planted a flag on a seabed in Russia’s Arctic waters in the summer of 2007, the specter of a circumpolar military race hung over the globe as other nations with …

Oil Spill Report Hits White House. Is it Fair?

Sometimes a President can’t catch a break—a lesson the current, beleaguered resident of the Oval Office keeps learning. The latest bit of bad news came from a commission the President himself appointed back in the spring to study the BP oil spill in the Gulf of Mexico. President Obama announced the creation of the study group on May …

Energy: Reducing CO2 Emissions Will Be Harder Than You Think

A little good news/bad news on the climate and energy front. In the Sept. 10 Science, Steven Davis and Ken Caldeira of Stanford University have a study that estimates what future carbon emissions—and consequent global warming—would be from existing energy and transportation infrastructure. (In other words, what would happen if we …

Climate Change: Are the Polar Ice Caps Melting Slower Than We Thought?

It’s one of the most pressing questions facing climate scientists today: how vulnerable are the vast ice caps on Greenland and Antarctica to rising temperatures? An unfathomable amount of ice is stored on those two land masses, and as that ice melts and flows into the oceans, global sea levels rise—if all the ice on Greenland …
