The hottest global warming burn we've ever seen

An astrophysicist had the best comeback when a climate change skeptic questioned her credentials.

Dr Catherine J Mack, a theoretical astrophysicist, whose Twitter handle is @AstroKatie, proved that snarky climate change deniers had better back off, right now.

One in particular, 'Gary P Jackson' (or @gary4205) felt the wrath of doctor Mack when he engaged with her on the topic of global warming.

@Gary4205:

Maybe you should learn some actual SCIENCE then, and stop listening to criminals pushing the #GlobalWarming SCAM.

@AstroKatie:

I dunno, man, I already went and got a PhD in astrophysics. Seems like more than that would be overkill at this point

BOOM.

The brilliant exchange was sparked when Mark tweeted about 'Q&A', an Australian current affairs program which was discussing climate change. Mark showed the world not to mess with scientists, especially when it comes to their credentials.
