On Monday morning President Obama headed to Alaska—the front lines of climate change—for a trip the White House is calling "a spotlight on what Alaskans in particular have come to know: Climate change is one of the biggest threats we face, it is being driven by human activity, and it is disrupting Americans' lives right now."Problem is, those words fall flat when compared with Obama's mixed record on climate. The widely publicized trip comes at a delicate moment for the president. Barely two weeks ago, his administration gave Royal Dutch Shell final approval to drill for oil offshore from Alaska's northwest Arctic coast—not exactly the sort of thing you'd expect from someone who professes to be "leading by example."
