Florida Democrat Bill Nelson used the annual Senate vote-a-rama to dis Republican Gov. Rick Scott’s alleged ban on the terms “climate change” and “global warming.”

Nelson has an amendment pending aimed at blocking federal agencies from censoring speech related to climate change. It would set up a procedural hurdle to Senate consideration of any future legislation that censors a federal agency’s use of climate change science.

Nelson called it “common sense” to protect those terms during a Thursday morning speech. “But we have all read news reports at the state level, at the local level, maybe even at the federal level that, indeed, some folks are trying to muzzle scientists from speaking about the science involving the oceans, the atmosphere, climate and the weather.”
