2. That's one kind of hot. Here's another. 1998 set a record for the highest average global temperature. British meteorologists think that 2007 is likely to match, or beat, that record. Greenhouse gases contribute to global warming, and in Canada they're still on the rise. By 2004 greenhouse gas emissions had increased by 159 million metric tonnes over what they were in 1990. About one quarter of that increase came from road transportation. So what do you know about greenhouse gases and transportation? Let's find out!
