"Week" in review: fracking, droughts, coldness, Kelvin-Helmholtz Instability clouds

Dec 23: Is natural gas fracking fracking up the ozone? Please donate to this UW researcher so she can investigate.

Dec 25: There's only 25-50% of the average snowfall in the mountains this year, due to lower-than-predicted precipitation.

Dec 27: Snow makes it cold, by reflecting sunlight away and keeping the earth's warmth underground.

Dec 29: Today we got beautiful breaking wave clouds (aptly named "Kelvin-Helmholtz Instability clouds"). They're caused by vertical wind shear: just the precise amount change in horizontal winds, relatively quickly in the vertical.
