First the disclaimer: None of what I say here is meant
to imply that I know exactly what is actually going to
happen. My whole point is that complex(chaotic)
systems are extremely difficult to predict which makes
me suspicious of anyone who claims to know exactly
what is going to happen.
One of the underlying assumptions in the global
warming case is that the recent trend of increased
global temperature will continue into the future. Here
is another interesting feedback loop that could throw
a wrench into that assumption:
The Atlantic heat conveyor could slow or even shut
One theory suggests that this mechanism may be
responsible for periodic rapid reversals of heating
trends in the past. Those past rapid coolings resulted
in drops of as much as 8 degrees in as little as a few
decades in the northern hemisphere. Such a large drop
in temperature could halt the melting of the northern
ice sheets and even cause them to grow.
In my previous post it was pointed out that increasing
energy prices caused demand destruction and
substitution. What should also be pointed out is that
falling prices causes demand to increase. In the past
few weeks the price of crude oil, as well as gasoline
has fallen more that 20%. During that same time, year
over year U.S. gasoline demand increases has gone from
1.4% to 3.1%. That is, growth in demand has more than
doubled with the fall in prices. That level of demand
growth is unsustainable, since the growth in world
production is only around 2% per year. And that
neglects the fact that car use in China looks be
growing at around 20% per year! So sooner or later,
energy prices may make yet another sharp reversal to
continue their long term trend higher.
In summary, both weather and energy markets are
complex systems, with feedback loops that cause them
to be volatile and highly unpredictable.
