Pretty much anything they want will be used as a cause for global warming...haven't you figured this out yet? They think everything causes global warming.
Also, every weather abnormality that has come along in the past 10 years or so is also...surprise!...blamed on global warming. Too hot? Too cold? Too wet? Too dry? Tornados....hurricaines...hailstorms...yep...all blamed on global warming.
Do you detect a pattern....yet?
