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.
Maybe you should learn some actual SCIENCE then, and stop listening to criminals pushing the #GlobalWarming SCAM.
I dunno, man, I already went and got a PhD in astrophysics. Seems like more than that would be overkill at this point
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.
