Climate scientists base future climate outlooks on current patterns in the ocean and atmosphere. They examine projections from climate and weather models and consider recent trends. They also check hi ...

the polar vortex doesn't come and go. It's not "here" because it's always there in our atmosphere, spinning around the winter hemispheres (Footnote #1). Look up as you walk. Way up. In scientific pape ...
