When it comes to global warming and the environment, everything seemed to change in 2006 -- at least in terms of public awareness. Here's an A-to-Z accounting of just some of those changes:
A is for An Inconvenient Truth, Al Gore's scientific but surprisingly human documentary on the threat of climate change, which was expected to take in at most $6-7 million at the box office but went on to gross over $45 million, the biggest documentary of the year and the third-largest of all time.
B is for biofuels, which went from becoming a hippies-only fringe product to a highlight of the State of the Union address. To date, Washington has been focused mostly on ethanol, but other fuels requiring much less fossil energy to produce are coming to the fore and proving surprisingly popular. Or as the bumper sticker says: "Biodiesel: No war required."
C is for California, which set a new standard for pollution control by passing a bipartisan package of bills designed to cut tailpipe greenhouse-gas emissions by 30 percent by 2016 (and many other measures). For this, Iain Murray, a fossil fuel-funded think tank writer for the far-right National Review, declared: "It is hard to escape the conclusion ... that what California has done is to decide to join the Third World."
