A new system for mapping carbon dioxide emissions in the U.S. will help regulators figure out exactly where these emissions are coming from and how best to reduce them. Among human-produced gases that contribute to climate change, carbon dioxide is public enemy number one.
It is increasingly accepted that rising levels of greenhouse gases are
contributing to changes in the world's climate. One of the main culprits is carbon dioxide. We exhale carbon dioxide when we breathe. Our cars, homes, factories, and the power plants that light our streets, all release carbon dioxide into the air. It's also emitted when fossil fuels are burned for energy. But that's about to change.
David Keith never expected to get a summons from the White House. But in September 2001, officials with the President's Climate Change Technology Program invited him and more than two dozen other scientists to participate in a roundtable discussion called "Response Options to Rapid or Severe Climate Change." While administration officials were insisting in public that there was no firm proof that the planet was warming, they were quietly exploring potential ways to turn down the heat.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
