Rubio's positions on global warming have shifted with political winds. As a member of the Florida legislature, Rubio acknowledged global warming, but during his Senate campaign in 2010, when his opponent Gov. Charlie Crist demonstrated his belief in global warming, the Tampa Tribune quoted Rubio saying of climate change, "I don't think there's the scientific evidence to justify it."
Since Rubio is under consideration by Mitt Romney to be VP candidate for the GOP slate in November, it is time for Rubio to clear the air. Why won't he meet with climate change scientists? But even if Rubio is not selected, as US senator for Florida, he should be agreeable to meet with climate change scientists. Why is Marco Rubio hiding?
