And now for the 2nd question: Does the massive cold air outbreak blanketing much of the U.S. disprove global warming?
Same word: no.
The media are mostly in stupid mode over this one.
Cliff Mass provides a good overview, the punch lines:
The bottom line: the claims that greenhouse warming causes more cold waves like we have seen this week really seems to be without any basis in observational evidence or in theory. The media needs to stop pushing this unsupported argument.
It is SO frustrating that every major weather event causes such claims and counterclaims to be aired, with many media outlets unable to do the minimal research that would allow them to give the public more dependable information. All this bogus reporting has done substantial damage, with many American’s believing that global warming is already causing our winter weather to become more extreme, while the observational evidence suggests no such thing. One day some sociologists will study this situation and the psychological elements that drove it.
The arguments in favor of an AGW impact on the cold air in the U.S. come from Jennifer Francis (see this previous post).

I am currently sitting in Atlanta Hartfield Airport, trying to get to New York City tonite, flights are still messed up. The more interesting challenge may be getting out of NYC tomorrow nite. In any event, in a few weeks I will be able to discuss what promises to be an EXTREMELY interesting meeting in NYC." via Climate Depot

"Climate Etc. provides a forum for climate researchers, academics and technical experts from other fields, citizen scientists, and the interested public to engage in a discussion on topics related to climate science and the science-policy interface....Climate Etc. is hosted by Judith Curry.
I am Professor and Chair of the School of Earth and Atmospheric Sciences at the Georgia Institute of Technology and President (co-owner) of Climate Forecast Applications Network (CFAN). I received a Ph.D. in Geophysical Sciences from the University of Chicago in 1982. Prior to joining the faculty at Georgia Tech, I held faculty positions at the University of Colorado, Penn State University and Purdue University. I currently serve on the NASA Advisory Council Earth Science Subcommittee and the DOE Biological and Environmental Science Advisory Committee, and have recently served on the National Academies Climate Research Committee and the Space Studies Board, and the NOAA Climate Working Group. I am a Fellow of the American Meteorological Society, the American Association for the Advancement of Science, and the American Geophysical Union. My views on climate change are best summarized by my recent Congressional Testimony:
