No one is denying science except the left. We're either born with XX or XY chromosomes. The left thinks the rest of the alphabet also exists.
Since 1997 the earth has not warmed so the left changed their prognostication from global warming to climate change. The problem is the left blames EVERYTHING on climate change including an asteroid passing closer than projected. And if we do not stop climate change in 9 years the some unknown thing will happen that scares Democrats and socialists to death.
Then Obama buys a mansion right on the edge of the ocean. Apparently he's not too concerned with the rising sea levels after preaching climate change was the most serious crisis facing the earth for 8 years.
