Unfortunately, the Kyoto emission cuts didn’t go into force until 2008; Canada, one of the world’s biggest oil producers, wouldn’t sign it; the U.S. didn’t ratify it, nor did Australia, one of the world’s top coal producers; China, India and the rest of the developing world weren’t covered by it; and its limits lasted only until 2012.  The result of the treaty was that 20 percent of the growth of atmospheric carbon dioxide since people lived in caves occurred between 2000 and 2011.

The words global warming used to mean something. When the term became popular in the early 1990s, it sounded like something out of a science-fiction movie. Today, however, it is thrown around casually and most people seem to have forgotten its implications. (Similarly lost is the significance of April 22 — Earth Day; don’t pretend like you remember.) Of course, there are those dutiful citizens who are doing their best to combat global warming: refusing plastic bags at the bodega; driving under 60 mph with the windows up and the air-conditioner off; and buying recycled paper towels. But the actions of a few have next to no impact on global climate change.
