If you look at the population change and carbon emissions over the
history of mankind on the planet, to not ascribe a significant amount of
atmospheric warming to human emissions over the past 2 centuries is
nothing short of willful ignorance.

Not only has the industrial age allowed economies to flourish, but also
enabled the population to explode. The same 200 years of emissions
output correspond to human population exploding from less than 1B to
over 7B. All while using carbon emitting fuels like there was no
tomorrow. (oops).

The naysayers desperately search for those warm periods in the past
while ignoring rate-of-change over short periods as we've experienced
over the last century as CO2 and other gases buildup. Now with
permafrost failure in the north, massive amounts of methane are leaking
and it is a far worse GH gas than CO2 - the feedback effect will simply
accelerate things. Of course those deniers will point to that as a
"natural cause" while ignoring the system that exposed all that
permafrost locked gas in the first place. Such is human folly.

No, by what they have published over the last 20 years.

That's why they did not at first sign up to the Kyoto protocol - until
they were bribed to do so.

Not a joke but :-) anyway.

The idiot gets it wrong yet again, preserving his perfect record. We
have ways of measuring the rate of warming and the rate since we began
pouring large quantities of particulates and CO2 into the atmosphere at
the beginning of the Industrial Revolution is unprecedented in geologic
time. The curves, warming vs. emission rates, match to an amazing
degree, pointing to one conclusion: human-caused global climate change.


1. Correspondence is not causation.

2. Apart for the last 60 years or so, atmospheric CO2 follows
temperatu CO2 fluctuations are not the cause of temperature
fluctuations.

Yet all but a blink in the geological time line. [Regardless of causation.]


Maybe so but CO2 following temperature seems to have gone on as long
as the ice records.

The fact that the temperature of the upper atmosphere of Venus is lower than
expected would be cold comfort to anyone trying to survive on the planet's
surface.The surface is where the greenhouse effect is felt, and the
temperature of its upper atmosphere is irrelevant to Venus's ability to
support life.

No argument there, but it's of no direct relevance to this planet.

The glaciation cycle may have been broken for the "near term" by AGW.
So whether the current 50ka prediction holds or is much shorter or
longer is in question.

They certainly try to ignore their existence. You should also read Dr
David Demings statement to a US Senate Committee:

"I received an astonishing email from a major researcher in the area
of climate change. He said, "We have to get rid of the Medieval
Warm Period."


Yes, I'm sure you can find all sorts of samples of one. These denier
nuggets are fodder for fools.


If you look at the population change and carbon emissions over the
history of mankind on the planet, to not ascribe a significant amount of
atmospheric warming to human emissions over the past 2 centuries is
nothing short of willful ignorance.


Atmospheric warming started well before mankind's contribution to
atmospheric CO2 became noticeable. I agree you can draw a parallel
between the current rise in atmospheric CO2 and global temperature but
correlation is not causation. In fact, when you examine the historical
record everything from the Vostok cores to the current detailed daily
records shows that the atmospheric CO2 concentration lags behind
temperature which surely demonstrates temperature changes cause CO2
changes and not vice versa (unless the source of the temperature
chages is telepathic).


While the factual nugget may be true for past, non-human driven, cycles,
the current change in temperature is driven by the massive amounts of
CO2 (etc.) that we pour into the atmosphere.

It is "convenient" to compare the past to the present. Until the
inconvenience that it is no longer the same laboratory - we have changed
the atmosphere considerably and so such comparisons are not valid.



Not only has the industrial age allowed economies to flourish, but also
enabled the population to explode. The same 200 years of emissions
output correspond to human population exploding from less than 1B to
over 7B. All while using carbon emitting fuels like there was no
tomorrow. (oops).


I agree with you (I think). The rate of population increase is a major
factor in the rate at which we are currently adding CO2 to the
atmosphere. Even though I am not convinced that CO2 is the cause of
the present temperature rise, I do not believe that we can go on
pouring CO2 into the atmosphere indefinitely. Both China and India are
planning to add a large number of coal fired plants and China may even
be planning to supply Europe with power by overland power lines.

The naysayers desperately search for those warm periods in the past
while ignoring rate-of-change over short periods as we've experienced

There is far more methane locked in, in submarine hydrates.


Which is irrelevant hand waving as long as they remain locked in. The
problem is the massive amount of methane that is being unlocked in the
north presently - not that that is still locked up under the seabed.
And that has been triggered by the rapid warming over the last half
century or so.

It was not I who introduced the temperature of Venus's upper atmosphere into
this discussion. I agree that it's irrelevant. Indeed, I thought I just said
so.

My point, which you haven't challenged in any meaningful way, was that since
most scientists ascribe the high surface temperature of Venus to a runaway
greenhouse effect, it behooves us to be careful not to inadvertently bring
about such an occurrence here on Earth. Venus,is, after all, about the same
size as we are and not much closer to the sun. Could we bring about such an
effect? Probably not, but I don't know that. And with all respect, neither do
you.

It was not I who introduced the temperature of Venus's upper atmosphere into
this discussion. I agree that it's irrelevant. Indeed, I thought I just said
so.

My point, which you haven't challenged in any meaningful way, was that since
most scientists ascribe the high surface temperature of Venus to a runaway
greenhouse effect, it behooves us to be careful not to inadvertently bring
about such an occurrence here on Earth. Venus,is, after all, about the same
size as we are and not much closer to the sun. Could we bring about such an
effect? Probably not, but I don't know that. And with all respect, neither do
you.

We would all be dead from lack of oxygen long before we got to that
point.

that's more than killed in automobile collisions.

it's time to ban cold weather.
