Re: The REAL point is ...
And I even pointed out that the term that can be used in different meanings, however since the discussion was about whether or not the cause of warming was relevant, that that referred to that discussion.

But the fact is that that discussion is still irrelevant and simply another attempt to palm the pea, move the goal post, find a way to not address THAT issue.

Re: The REAL point is ...
Apparently, I am leaving the wrong impression. I believe that we are already well passed the point where action should be taken, and have in fact reached the point where our failure to act has had negative consequence.

So we agree that it's >75% human caused.

I am taking issue with the claim that the relative size of the human contribution is of no importance. That's simply incorrect.

Allow me to come from a different angle: what can we do ...

What action can we take that gives the most "bang for the buck" in reducing climate change?

reduce atmospheric CO2 emissions (fossil fuel use)?
reduce volcanic action?
reduce solar radiation?
change the earth's orbit?
enhance natural CO2 take-up systems (trees, algae, etc)?
other _______?

What action can we take as individuals to assist reducing climate change?

reduce motor-vehicle use?
reduce plastic use?
utilize solar panels?
utilize wind power?
campaign for political change?
educate others?

Does the relative size of human caused climate change affect these answers?

Enjoy

I think we'd be better off if we had never figured out that the globe was warming. We could be reducing our use of fossil fuels because they pollute the air we breathe.

"I think we'd be better off if we had never figured out the the globe was warming".

Maybe you are right. I personally think that the politics behind clean air is at an even higher level of denial than is that of global warming. People are willing to argue that not having a job is just as harmful to your health as smog. Of course that turns out to be true only because of our equally dicked up health care system which denies care to folks without lots of money.

Re: Climate Is Warming And Humans Are The Cause

Sigh. I have addressed this question a number of times, including in the post you are responding to. Yes, CO2 is a greenhouse gas. If you believe that to be the only factor that needs to be considered, then you have an overly simple idea of the science behind AGW.

I never said that it is the only thing that needs to be considered. I said that it is the OBVIOUS part. It is OBVIOUS that no matter what contribution humans are making to warming, we are still making a contribution because we are increasing the concentration of greenhouse gases in the atmosphere.

Again, CO2 is pumped into the atmosphere by humans, and it is also removed by a number of mechanisms. Things other than people also put CO2 and other greenhouse gases into the atmosphere. There are also things like water vapor, methane, etc. Some of which have man-made and natural variation each having its own "half-life" within the atmosphere.

The previous 400,000 years has seen several ice ages and interglacials that bounce between 200 and 300 ppm CO2. The graph suddenly jumps to 400 ppm, an increase of 30%, and it does so during the time when we are burning gigatons of CO2. I think it is rather obvious that humans are increasing CO2 well above natural levels.

The argument that this is a natural level of CO2 just doesn't stack up. On top of that, the half life of water in the atmosphere is about 2 weeks. People know this as rain, which they should be familiar with. They can watch weather radar where water evaporates off the oceans, sweeps inland, and then dumps rain. All this happens in a matter of weeks.

We know the conclusion of those processes only because they fit of complex models that most of us don't understand fully, and the tracking of those models of the atmosphere, ocean, etc with temperatures we've measured along with other analysis that rules out the idea that what we understand to be the human contribution is either attributable to non-humans or to errors in measurement.

You don't need models or anything complicated to show that humans are causing more heat to be trapped in the atmosphere. Again, we are talking about the OBVIOUS parts, not the complicated parts.

Re: Climate Is Warming And Humans Are The Cause
Unless you want to argue that it is irrelevant whether we have 2 degrees or 0.2 degrees increase (due to human contribution of course) in temps over the next 50 years, then modeling does matter. It is not possible to make reasonable policy decisions on human activity without such information.

Edited by NoNukes, : clarify meaning.

I think you need to go back one step. Your standard AGW denier out in the public may not even understand what the greenhouse effect is, how it works, or what makes CO2 a greenhouse gas. They may very well deny that pumping CO2 into the atmosphere traps heat. Once you convince them that CO2 is a greenhouse gas, the rest of the conversation may go a lot easier.

Edited by Taq, : No reason given.
