Yes there is, but not about its cause. There is not a consensus that it
is CO2 caused. Many think that CO2 increases are simply an effect (which
would jive with the fact that studies of increases in coal burning (i.e
CO2 production) FOLLOWED increases in average temperatures.

There is good evidence that at least 1/10th to possibly as much as 1/6th
of the CO2 content is human produced. There is no evidence to account
for changes in nature's ability to absorb CO2. If warming caused by
solar action reduces natures ability to absorb CO2, then no amount of
measures by humans can prevent CO2 from rising. Moreover, the curve of
CO2's ability to function as a greenhouse gas is one of diminishing
returns as content rises. Right now, we are at an almost flat point in
the curve: more pollution will do little to increase warming, while the
sky-is-falling types are treating it like it is a linear relationship.
> There is good evidence that some of it is solar bases.
Yes, even the greens acknowledge that at least 1/3 of the warming is
solar caused. There is no consensus about whether the solar caused
component has influenced obsorption rates, etc, which would drastically
alter this estimate. Some think that direct and indirect solar action
has caused at least 3/4 of it, part of which is a matter of our use of
CFC's in aerosols: solar UV levels rising kills more plankton that would
normally be absorbing CO2, thus CO2 absorption is reduced. This can be,
and has been, directly measured in krill populations in the southern
ocean. The greens refuse to acknowledge this mechanism as 'solar
caused'. While our CFC use is also directly implicated in this
phenomenon, our complicity is over and CFC content is waning, while the
greens continue to count this impact with CO2 production...

Yes, the three Malenkovich cycles, for instance, correctly predict the
current warming trend...

However, the as the models get more sophisticated, they continuously
are downgrading the severity of the projected temperature change. At
present, it is already far below the level that would have enough impact
on the poles to melt the above sea level ice sheets. This means the
'flood' warnings are boving excrement, to say the least.

What I do know is that every degree of removal from direct impact always
results in reduced impact.
The fact is that the caribou populations have soared and crashed back
and forth in the past. There are now many times more than there were a
century ago. Polar bears may not be able to go out to sea as much to
hunt seals, they will be limited to caribou and those seals that come up
on the beach. None of this impacts humans in any way, Anne. We've seen
far more severe environmental changes in the historic and pre-historic
past than are currently projected, without any significant impact on
humans. The sky is not falling.

We dont' live in a monoculture. What experiments do say that ecosystems
can do just fine with a limited number of species. Any more than a dozen
and you are back on top of that diminishing returns curve again. Mild
diversity is just about as good as broad diversity.

Actually, several of us have flown 747 simulators a number of times.
I've got mine configured with x-plane, I've even got several different
747 models to choose from (and skin designs). Flying a plane is not that
tough. Most of the 'training' in a formal setting is training one to
deal with wacko situations without freaking out. Those situations aside,
driving a 747 is like driving a bus.
What is important is situation awareness. Most of the people freaking
out about 'global warming' are NOT any sort of scientists, and those
that are are doing so because they find that this is a means to an end:
the institution of their socialist agenda. Its like I'm flying the
plane, but the passengers are freaking out that we're gonna crash
because one guy is claiming to be a pilot and says we are gonna crash,
when in actuality he's just a terrorist.

That's one way of looking at it, and properly balanced.
Then there is the 'fast rise' contingent: we, like any fetus, have no
use for its placenta once it's born. If Earth is as inconsequential in
the universe as many claim, there are boundless other ones out there.
Boundless resources are not worth using with a conservation mindset.
