Temperature changes do NOT track CO2 levels (which have been rising steadily) but they DO track oscillations in ocean currents
ENSO stands for the El Niño-Southern Oscillation, a huge current in the vast Pacific ocean. And that El Niño sure is powerful. I live in a city where it has just caused billions of dollars worth of flood damage -- JR
The graph above plots the five year running mean of ENSO (red/blue) vs. HadCRUT in green.
Temperatures rise when ENSO is positive, and they don’t rise when ENSO is negative. Sea ice increases when ENSO is negative, and it falls when ENSO is positive.
But there is a $2.5 billion industry built up around CO2 – so we can expect the stupidity to go on at least until January 20, 2013.
