Pepsi, to me, was the perfect beverage. Coke was a bit too dry, and Dr. Pepper had too heavy a taste. Its delightful carbon dioxide bubbles tickled the nose and the throat as you sipped it. The mild after taste was just acrid enough to make the next taste that much more pleasant...
That kind of derision doesn't faze the feisty Guidon. On the charcoal deposits, she argues, "If they had been left by forest fires, carbon deposits would have been found scattered across a wide area." They are not. In many cases, the charcoal is ringed by stones, says Guidon, which is strong supporting evidence that these were man-made hearths, not natural formations. Besides, the area was a humid, tropical rain forest 30,000 years ago, and natural fires would have had a hard time getting started...
...year's Earth Summit in Rio, Clinton declared that the U.S. would sign an international treaty to protect the diversity of living species. And the President followed through on a pledge that briefly seemed in jeopardy: he committed the U.S. to a specific timetable for curbing the release of carbon dioxide and other so-called greenhouse gases believed to be causing a long- term rise in temperatures around the globe...
That will not be easy. America was built on cheap and seemingly unlimited supplies of carbon-based fuels -- wood, coal, oil and natural gas. With only 5% of the world's population, the U.S. today produces nearly 25% of global carbon emissions. If nothing is done, the country will be pouring 100 million more tons into the atmosphere by the turn of the century...

Clinton has already proposed a tax on various forms of energy that would take the country about a quarter of the way to the target for carbon dioxide reduction. But even this modest proposal is running into opposition, and it is hard to imagine a more ambitious tax getting anywhere on Capitol Hill...
