"So why are some scientists now beginning to question the buoys'
findings? Because in five years the little blighters have failed to
detect any global warming. They are not reinforcing the scientific
orthodoxy of the day, namely that man is causing the planet to warm
dangerously. They are not proving the predetermined conclusions of
their human masters. Therefore they, and not their masters'
hypotheses, must be wrong."

Read a little further - the "cooling effect" is actually a sign of
"global warming".

Typical.
