No it's real , but it's not caused by man. That's just a scare tactic used by democrats and phony bologna scientists. They were just recently busted faking their data. The earth has cycles and there's just nothing we can do about it. Like above said look at the snow we had in Texas this year. More than I've ever seen in my life.
This Librarian recommends you research your answer in professional, peer-reviewed literature (serials/periodicals/books) written by formally trained experts. These scientists do not write their literature alone but collaborate, debate, and mark trends in climatology and more specifically, forensic climatology and inter-disciplinarily with geological records. It has been my personal experience that the majority of respected, reputable, professional climatologists and geologists agree we are experiencing global warming.
It is the CAUSE of this global warming that has been a political football of recent: in other words, determining if man has contributed to what may already be normal fluctuations in climate by his burning of carbon fuels, propellant aerosols, the increase of meat animals producing gases, the elimination of rain forests by the populaces eeking out their survival through the selling of the resources and clearing to raise food animals and raise crops, to name a few, all contributing to the green house gases/effect which can affect global climate.
