bring it on! you should read about how warming in north pole causes polar vortex to push further south. pretty amazing stuff. humans have no control over what happens to Earth, it does what it wants to do when it wants and external factors can also have huge impacts (no pun intended) the sun is a huge player in global warming just as volcanic eruptions. one volcanic eruption in the 1990's actually caused global earth temps to dip for about two years.
