There are claims even among Global Warming supporting

the Central Asian landmass to the East.

Oh, God, not cyclemania again :-( As with most other areas where
people have claimed to discover cycles (and the reason is not
obvious), there is damn-all evidence for them. Most of the time
the series is almost certainly an ARIMA model of sorts (think of
that as a correlated random walk).

Any extrapolation of climate change based only on around 100 years
worth of hard data of varying quality and reliabilty will
of necessity require a fair amount of conjecture.

If you're of the opinion that your conjecture is superior to that
of the meteorologists whose opinion I quoted then good for you.

All else is hand waving IMHO.

There is one thing for sure - it's going to get a whole lot hotter around
here in 6 billion years or so.
