So, what does Wagoner think about global warming? Wagoner says "the data is pretty clear that the temperature on the earth is rising." Saying the globe is warming is quite different than saying humans are a significant contributer to that warming. The "non-confrontational" Wagoner, as the Journal describes him, has never said he believes in global warming or not (see 37 minutes into the video below the fold).
What's GM doing about global warming? Wagoner says "it makes sense for us to put the business in a place where can respond productively." Wagoner also says that "a lot of things need to be done to address CO2" and that GM is investing "a huge amount of money" to fulfill the company's responsibility as a big player in society. In the past Wagoner has said electric cars don't look like the answer but GM has come around to the idea.
