Sarah Palin, climate scientist

[marmar]

Sarah Palin says man isn’t to blame for climate change, citing the fact that some glaciers in Alaska are expanding. But an individual glacier’s growth does not disprove the existence or causes of global warming. In fact, the vast majority of glaciers in Alaska and around the world are losing ice rapidly.

Palin, the former Alaska governor and 2008 vice presidential nominee, appeared on CNN’s “State of the Union” (at the 2:25 mark). Host Jake Tapper asked if she takes climate change seriously, and Palin responded:

[font size="4"]"I take changes in the weather, the cyclical changes that the globe has undergone for — since the beginning of time, I take it seriously, but I’m not going to blame these changes in the weather on man’s footprint. Obama was up here looking at, say, the glaciers and pointing out a glacier that was receding. Well, there are other glaciers, though, that are growing up here. And he didn’t highlight that, but he used glaciers as an example."[/font]

Palin may not blame climate change on humans, but science does; we have covered before how scientists say it’s extremely likely that most of the observed temperature rise has been caused by human emissions. Her claim that some glaciers are growing in Alaska is true, but this isn’t a reason to question human-caused climate change. Regional variations in precipitation patterns may cause some glaciers to grow, but most glaciers around the world are losing ice as the climate warms. ................(more)
