It's a big image so I'm sorry if it's too big for the monitor.
But anyway, the point is, they think Burmese pythons can live in ALL of the green areas, RIGHT NOW! They don't see this cold snap as an issue. They truly believe this "science", and that's sad.
Just for the sake of reference, here's the map with a global warming scenario in the year 2100 included:
This "science" is why these legislators believe this bill is needed. They believe in it. It's our job to change their beliefs.
