THE OMEGA BLOCK CAUSED THE HEATWAVE NOT CO2! "Omega blocks get their name because they resemble the Greek uppercase letter omega, Ω. The contour lines resemble the Ω shape due to an enormous high-pressure ridge in the mid-troposphere that is sandwiched between two low-pressure systems to its east and west. Hot Saharan air has been advected—that is, horizontally transported—northward into western Europe due to anticyclonic (clockwise) airflow, and as that air mass moves north, it is compressed adiabatically beneath the ridge where air is sinking. This process is natural and has nothing whatsoever to do with climate change or greenhouse gas emissions." Chris Martz, Meteorologist
