Cold weather in USA in no way refutes climate change

A Response For People Using Record Cold U.S. Weather To Refute Climate Change, Forbes, 

Marshall Shepherd , 28 Dec 17
 “……..Weekly or daily weather patterns tell you nothing about longer-term climate change (and that goes for the warm days too). Climate is defined as the statistical properties of the atmosphere: averages, extremes, frequency of occurrence, deviations from normal, and so forth. The clothes that you have on today do not describe what you have in your closet but rather how you dressed for today’s weather. ……
our weather is governed by a series of undulations or wave patterns. The “valleys” (troughs) in those waves allow cold, dense air to ooze into the U.S. The “hills” (ridges) in the waves are typically associated with warm conditions. If you search Arctic Amplification on the Internet, there is some evidence that climate change is causing more wavy, high amplitude “valleys” and “hills” in the jet stream pattern. This could be associated with more extreme cold events and more extreme heat/drought events. The science is still emerging on this process, but it should be monitored and not dismissed.

The other thing to point out is that because one part of the world is cold (in that valley), there is likely another part of the world experiencing abnormally warm conditions (in the hill part of the wave pattern). In the temperature map tweeted by long-time weather observer Joe Stepansky, it is clear that on December 28th the United States and parts of Canada are experiencing the anomalously cold weather. …..

there are some studies that suggest that a warming climate (because more water vapor is available to a warmer atmosphere) may fuel bigger blizzards or snowstorms. That science is also emerging…….https://www.forbes.com/sites/marshallshepherd/2017/12/28/a-response-for-people-using-record-cold-u-s-weather-to-refute-climate-change/#4a0c5c6a5680
