UPSIDE DOWN WEATHER

It appears that the world's weather has flipped upside down. For two winters running, an Arctic chill has descended on Europe, and in the United States, historic blizzards afflict the mid-Atlantic region. The Deep South in the United States has endured unusual snowstorms and severe cold.  The jet stream is descending, possibily because of melting sea ice.  Climate change is affecting us.  Tell us your opinons.
