Re: Calculating your carbon footprint - a load of bollocks

If that page 25 graph is correct Monckton's claim that a pronounced
downward trend dates from late 2001 is patently false.

Right to be cautious wasn't he given that just a few months later the
summer limit was setting a new record low.

Logic doesn't seem to be your strong point either or you wouldn't quote
in support of a claim that "In the cold winter of 2007/8, record sea-ice
extents were observed at both Poles." an article that clearly refutes
it.
