...pollution and wildlife issues, while the new Ministry of Climate and Energy was formed to focus specifically on global warming and alternative energy, with an eye toward preparing the way for Denmark's leadership on climate change - at the UN summit and at home, by further reducing its own carbon footprint. "We know we have a responsibility for Copenhagen," says Connie Hedegaard, the Danish Minister for Climate and Energy. "We'll live...
...those twisty carbon fluorescent lightbulbs. We can unplug our televisions, computers and phone chargers when we're not using them. We can seal our windows, install more insulation and adjust our thermostats so that we waste less heat and air-conditioning. We can use more-efficient appliances, build more-efficient homes and drive more-efficient cars, preferably with government assistance. And, yes, we can inflate our tires and tune our engines, as Republican governors Arnold Schwarzenegger of California and Charlie Crist of Florida have urged, apparently without consulting the RNC. While we're at it, we can cut down...
...other ways to reduce demand for oil - more public transportation, more carpooling, more telecommuting, more recycling, less exurban sprawl, fewer unnecessary car trips, buying less stuff and eating less meat - that would require at least some lifestyle changes. But things like tire gauges can reduce gas bills and carbon emissions now, with little pain and at little cost and without the ecological problems and oil-addiction problems associated with offshore drilling. These are the proverbial win-win-win solutions, reducing the pain of $100 trips to the gas station by reducing trips to the gas station. And Americans are already...
...climatic history. At this depth what they bring back is not solid ice, but a half-snow, half-ice substance called firn. It's solid but porous, so it can trap some of the gas present in the atmosphere when it accumulated as snow. They can tell how much carbon dioxide was in the air during a given time period (roughly seven years with each layer, because in the porous firn - unlike the frozen ice below - air from different years can mix over time), and by analyzing oxygen isotopes inside the firn, they can tell the temperature as well. Johnsen...
...bottom, you can read the climatic history of the island as if you were counting tree rings going back tens of thousands of years. Oxygen isotopes trapped in the ice core can tell you what the temperature was in a given year; trapped air bubbles can reveal how much carbon dioxide and other gases were in the atmosphere at a particular time. You can even trace impurities that were in the air during the Roman Empire to a specific lead mine in Spain, according to J.P. Steffensen, one of NEEM's field leaders...
