Explain this graph:

http://www.koshland-science-museum.org/exhibitgcc/historical02.jsp

It looks to me like there is a 100,000 year cycle of warming and
cooling.

Did you notice how current CO2 levels are higher than at any other point
in that graph?

So what is the current "crisis" all about?

Oh, so did you finally pull your head out of the sand?

The looming crisis is that CO2 traps heat in the atmosphere and that
with all that extra CO2, temperatures will become higher than is good
for us.

How high is "higher than is good for us"? Looking at the graph, our
ancestors must have survived similar changes in climate. It has been
both hotter and colder than it is now, and humans have survived just
fine. Current conditions are not necessarily 'perfect' for humans, they
are just what we are used to. Doesn't it make more sense to learn to
adapt to changing conditions than to make drastic changes to our way of
life in an effort to stop what may actually be a partially or even
entirely a 'natural' process?


What an incredibly stupid argument: "Our ancestors must have survived,
therefore why worry?"

While human beings in general will almost certainly survive, a major
change in average temperature (and a few degrees *is* a major change)
will result in hardship for many, many people in *specific*.



Apparently we need do
nothing and it will reverse by itself, right? We're not even at the
highpoint from the past!

You only have three "cycles"; that's not enough to determine whether
we've peaked yet or not. And then there's all that extra CO2 that's not
usually there.

So why is the current cycle "man made"? What caused the previous
cycles?

No, the cycle is not man made; the realy high level of CO2 is.

You sort of sidestepped his question - the graph shows that this cycle
of increased CO2 and higher temperature has happened before, without any
help from humans. So how much of the current bump in CO2 is due to
humans? The graph makes it look like there was going to be an increase
with or without human help. Even if we stopped producing CO2 today, the
graph makes it look like the current cycle would continue. So the
question you sidestepped - if CO2 levels have repeatedly increased in
the past without human intervention, what caused that to happen, and how
are we sure that isn't happening again now? - is pretty important.

Look more closely at the graph:

The previous highs for CO2 have never been more than about 300ppm.
Today, we're at 380ppm; more than 25% higher than at any time in the
past 300,000 years.



Like I said, it's all about politics.

Not for the environmental scientists who see these data and, because
they know more than you do, draw alarming conclusions. The politics
comes in because many rich and powerful people are heavily invested in
the causes of unusually elevated CO2 levels.
