It correlates strongly with the increasing CO2 levels and no other
corresponding natural variation of the solar flux can be found to
explain away the most recent temperature rises. It is constrained by
satellite observations so you cannot just magic the sun to be brighter
and keep on trashing the environment for fun and profit.

The temperatures were increasing *before* we started putting CO2 into
the atmosphere in any quantity, and indeed have increased many, many
times before man even evolved.

After about 1970 even the sceptics cannot balance the global energy
budget to explain the observed warming without including the effects of
GHG forcing. Changes in the past four decades mostly due to AGW are
roughly at the same magnitude as 140 years of natural climate change and
we are still pumping ever more CO2 into the atmosphere.

On the evidence to hand, anthropogenic CO2 is clearly *not* the cause of
global warming.

Logic was never one of your strong points was it?

It's so tiring to see people still use that "X can not cause Y
because Y happened before X" fallacy/rationalisation.

They apparently can't see their "rule" implies junk like "murder
was impossible before the gun was invented".

But at least sometimes you can get a LOL from the professional knuckle-draggers.

I once had a guy seriously argue that humans can't be the cause
of something that can't be reversed by human agency.

Apparently he never though of "I can not be the murderer, M'Lord,
because it's impossible for me to reantimate the corpse".
