Global Warming on Free Republic
Posted on 10/24/2009 1:11:23 PM PDT by reaganaut1
Campaigners against global warming have drawn on an arsenal of visually startling tactics over the years, from posing nude on a Swiss glacier to scaling smokestacks at coal-fired power plants.
On Saturday, they tried something new with the goal of prodding countries to get serious about reaching an international climate accord: a synchronized burst of more than 4,300 demonstrations, from the Himalayas to the Great Barrier Reef, all centered on the number 350.
For some prominent climate scientists, that is the upper limit for heat-trapping carbon dioxide in the atmosphere, measured in parts per million. If the gas concentration exceeds that for long, they warn, the world can expect decades of disrupted climate patterns, rising sea levels, drought and famine.
The current concentration of carbon dioxide is 387 parts per million.
Organizers said their goal, in the prelude to global climate talks in Copenhagen in December, was to illustrate the urgent need to cut emissions by pointing out that the world passed the 350 mark two decades ago.
Yet while agreeing that unabated emissions pose serious risks, some prominent scientists and economists focusing on climate policy said the 350 target was so unrealistic that the campaign risked not being taken seriously — or could even convey the wrong message.
“Three-fifty is so impossible to achieve that to make it the goal risks the reaction that if we are already over the cliff, then let’s just enjoy the ride until it’s over,” said John M. Reilly, an economist at M.I.T.
“The message needs to be that there are risks at the current level, and those risks increase the further we push the system,” he said.

350 is about the number left who buy into global warming.
Let's give it a try, eh?
Inclusive of those who have passed on do to natural causes.
Strange, my detailed amalysis indicates an optimum CO2 concentration of 411.38 ppm, meaning we better start just burning oil and gas even if no energy is extracted.I sure would like to see their detailed analysis. They must have an error somewhere (which I’ll happily point out to them).

Never mind that, geologically speaking, the CO2 levels are at their lowest ever, and that levels used to be more than 10-fold what they are now. The levels of CO2 have plummetted over the last 500k years.
I’d be more worried about the geologically low levels of CO2 than the minor reverses humans may or may not have contributed to in the last couple of decades.
Without CO2, there can be no life.
Except that even when humans dramatically reduce the burning of fossil fuels, the atmospheric CO2 content rises inexorably on:

And where in the instruction manual did we find this magic 350 number?
If the increase is caused by humans, this number will be impossible to achieve. We will have to live with no heat, electricity, industry, or cars.
If the increase is NOT caused by humans, it will also be impossible to achieve.
I just hope to stay warm this winter without breaking the budget. The first 19 days of this month here, every day’s low was below normal.
We can do this!
Just discharge MORE METHANE into the atmosphere (any way you can) and we'll get that number down to 350!
387 ppm - 350 ppm = 37 ppm
37 ppm in 1.794x10^18 kg of atmosphere (roughly) gives excess CO2 of 66.3 billion metric tons.
If I remember correctly, the world wide consumption of crude oil is ~80 million bbl/day. 1 bbl of crude =~248.8 lbs Carbon. or 19.9 billion pounds a day. I don't have the numbers for natural gas, coal, peat, wood, but it seems to me that if we just took an energy holiday, about 3 days a year would do it to close the gap without spending trillions of dollars.
(Of course the real point is population control, they could care less about the planet)

You first.
Oh, I forgot: CO2 is only 27% carbon, so reduce the excess above accordingly.
How did they get 350 ppm, throw darts at a board? Oh, wait, I could’ve guessed... Something less than we have now, thus providing some impetus for action. Not just a little less, or there might not be a sense of urgency. Not a lot less, or there may be no hope. No, “just right” less than we have now in order to try to spark action - redistribution of wealth and power.
350 is the classic Chevy engine.
I think some of them have been celebrating 420.
its a shame that carbon dioxide has nothing to do with global warming. Its also too bad there is no global warming.
