A seemingly innocuous Twitter post from scientist Bill Nye linking historic flooding in Texas to climate change sent conservatives into a frenzy this week. According to Scientific American, Houston saw 10 inches of rain within 24 hours on Monday, causing what Republican Gov. Greg Abbott called the "the biggest flood this area of Texas has ever seen." For climate scientists like Brenda Ekwurzel of the Union of Concerned Scientists, the link to a warming planet was obvious. “When you have a warmer atmosphere, then you have the capability to hold more water vapor," Ekwurzel explained.
