Looks like it probably originated from some rubbish anti-science blog that just made stuff up, not the DOE. (not surprising, as it was complete nonsense)

Edited to add: The 'data' looks like it originated from Monte Heib's pseudoscience blog 'geocraft'. No wonder it was nonsense.

Honestly, no. First it was trapped heat but now the conversation seams to be shifting towards "enhanced" heat.....exactly like the shifting from "global warming" to "climate change".


So when did 'they' 'shift from global warming to climate change'?

Bearing in mind that the 'CC' in IPCC stands for climate change and that the IPCC was formed in 1988.

If you look at the history of the development of the science behind climate change/global warming you will see that both terms are used. Global warming causes climate change. Pretty obvious.

Don't be stupid. You know this whole crock is about the narrative. "Global warming" wasn't selling for 20 years. Not enough people bought it. I was taught global warming in grade school in 1980. I bought it for a while. But then 20-30 years later no predictions of disaster came true. New York was dry!! You guys had to change the narrative to something a little more sexy. It may have always been climate change, but it was global warming till about ten years ago.

You are advocating anti environment policy and are being deceptive in order to do that. As far as I can tell you have no concern about objective truth and see this all as a game against your perceived opponents. You aren't alone in this. Why people want to do this I have no idea, perhaps your mother did not hug you enough when you were a baby or something.

How? I've told no lies. However I have put up stories about 5 million dead every year due to global warming. That is not deceptive?

It was only after it was pointed out to you that it wasn't from the DOE that you changed your story and admitted that it wasn't. But you added some conspiratorial nonsense as well about it 'mysteriously disappearing'.

It was obvious it came from some junkscience conspiracy blog and you were gullibly fooled into believing it came from the DOE. You just forgot which conspiracy blog you got it from.

As Ceist said that was not your first post on the graph the first one was;

"but I have a Dept Of Energy graph(which is now nowhere to be found online,I suspect they were told to obliterate it) saying it's as high as 96%, which would put mans contribution to total greenhouse gas at 1 tenth of one percent."

You would have us believe that the DOE are making a ridiculous claim and forces unnamed are suppressing it.

Why go through the bother of proving how you are being and are continue to be deceptive when anyone interested could read the thread all the way through?

OK, here's what I have gotten from the original subject "So is the feedback positive or negative", both through posts to this thread other searches:

The predominant opinion is that feedback on global temperature rise due to CO2 increase is that it is positive. This is primarily due to water vapor greenhouse effect. Because of this effect, the moderate temperature increase due to CO2 alone is leveraged to harmful levels. Ice core studies indicate that this phenomena accompanied past recoveries from ice ages. There is no doubt that CO2 concentration in the atmosphere is increasing and some (most?) of this is caused by mankind. Why this phenomenon also occurred after ice ages, without help from mankind is not clear to me.

There still remains a body of evidence that the feedback is negative, and/or that the present warming is caused by forcings unrelated to CO2. Some of this is the UAH satellite measurement of radiation entering and leaving the planet, the Milankovitch Cycles, and the "Reduction of Climate Sensitivity to Solar Forcing due to Stratospheric Ozone Feedback".

I guess this, in a nutshell, is why there still is a climate debate.

No, you're not sceptical at all. You gullibly and un-sceptically swallow whatever you want to believe from crap junkscience conspiracy sources, yet flat out deny/reject evidence-based facts and science.

With respect to the recent floods and droughts, these are examples of weather, not climate. The difference between weather and climate is a measure of time. Weather is what conditions of the atmosphere are over a short period of time, and climate is how the atmosphere "behaves" over relatively long periods of time.

Why do you keep parroting this idiotic claim that only 3.2% of the CO2 in the atmosphere is man-made? What possible justification can there be for this?

You did see the graph from the DOE right?

We know that CO2 levels had been roughly constant at about 280 ppm over the past 10,000 years, we know that they started to rise at an increasing rate with the start of the industrial revolution, and know that human emissions have been more than sufficient to account for the rise to, currently, 405 ppm.

That's why I quoted you and your claim of 30%. Did you just get too pissed off to read?

It is utterly illogical to claim that the increase in CO2 from 280 ppm to 405 ppm is due to some other unidentified cause, when the very obvious fact of human CO2 emissions easily accounts for it.

Maybe, but it also seems quite illogical to think we can change the climate when we are responsible for less 1% (your figure of 30%) of all greenhouse gasses.

If the temp has risen 1 degree in 100 years, you could also say man has raised the temp 1 100th of a degree in 100 years, or 1 1000th of a degree in the last decade.....but 5 million people are dead every year due to the global furnace.


As usual we get the BS crowd ready willing and able to spread disinformation.

https://en.wikipedia.org/wiki/Carbon_dioxide_in_Earth's_atmosphere

CO2 comprises (at present) 0.04% of the gases in the atmosphere.

The reaction has been:

https://www.skepticalscience.com/co2-levels-airborne-fraction-increasing.htm

If you observe the chart in this article you will see that CO2 has been increasing at a linear rate from 1850 to 1950. It then increased it's growth but again at a linear rate from 1960 to present.

However, the growth in CO2 generated by man hasn't been completely linear: the use of fossil fuels since 1775 has been exponential.

https://www.eia.gov/todayinenergy/detail.php?id=10

So there appears to be NO direct connection between the growth of CO2 and the generation of that gas by man.

Also - we know that there are other sources that are supposedly increasing the CO2 in the atmosphere quickly:

https://www.scientificamerican.com/article/melting-tundra-releases-carbon-dioxide-quickly/

https://www.newscientist.com/article/dn20413-warmer-oceans-release-co2-faster-than-thought/

What all of this means is that there is FAR more CO2 released than man produces and the levels of CO2 in the atmosphere does NOT respond to the release in any manner that we can understand.

So the very fact that the True Believers are addressing this as some sort of man-made global warming makes one wonder why they would do so? This is pretty obviously some sort of mental problem in which they MUST find reasons and it MUST be someone's problem (other than their own of course.)

Planck's law says that energy in equals energy out. So the feedback is ALWAYS negative. The more energy inserted, the more is released.

But with a catch - the mechanism in which the energy is both received and released can change so that the atmosphere in between can APPEAR to be a positive feedback mechanism.

For instance: There is a hypothesis that a warmer atmosphere will cause more evaporative cooling at the surface and that this water can form more low level clouds trapping heat so that it causes yet more heating in the lower atmosphere. H2O does this by having a very high latent heat content and it requiring a lot of energy before it will radiate.

In practice this isn't a problem because most of the heat in the lower atmosphere is not carried via radiation but rather conduction. The transfer of energy from molecule to molecule by each mechanically bumping into another as they vibrate from the energy they are carrying. Conduction and radiation operate in 360 degrees but that which goes up is eventually lost to space via radiation.

CO2 has a lower latent heat content than other gases. This means that it takes LESS heat to cause a CO2 molecule to RADIATE. And again although this operates 360 degrees and radiates a large portion back towards the earth - that which is radiated into space is lost forever. Remember that CO2 is a minority gas and that ALL of the other gases operate in the same manner but require slightly higher amounts of heat to trigger radiation.

Planck's law says that energy in equals energy out. So the feedback is ALWAYS negative. The more energy inserted, the more is released.

But with a catch - the mechanism in which the energy is both received and released can change so that the atmosphere in between can APPEAR to be a positive feedback mechanism.

For instance: There is a hypothesis that a warmer atmosphere will cause more evaporative cooling at the surface and that this water can form more low level clouds trapping heat so that it causes yet more heating in the lower atmosphere. H2O does this by having a very high latent heat content and it requiring a lot of energy before it will radiate.

In practice this isn't a problem because most of the heat in the lower atmosphere is not carried via radiation but rather conduction. The transfer of energy from molecule to molecule by each mechanically bumping into another as they vibrate from the energy they are carrying. Conduction and radiation operate in 360 degrees but that which goes up is eventually lost to space via radiation.

CO2 has a lower latent heat content than other gases. This means that it takes LESS heat to cause a CO2 molecule to RADIATE. And again although this operates 360 degrees and radiates a large portion back towards the earth - that which is radiated into space is lost forever. Remember that CO2 is a minority gas and that ALL of the other gases operate in the same manner but require slightly higher amounts of heat to trigger radiation.



And,I believe that there is a delta t in the radiation equation, so, since outer space is colder than the earth, more energy radiates to space than to the earth.

The reason why CO2 levels have increased from about 280 ppm to over 400 ppm since the industrial revolution is entirely due to mans influence, the bulk of that increase is due to fossil fuels but there is some evidence that land use changes and melting permafrost also have an impact.

As for the residence time of an individual molecule in the air that's a complex question and requires work on my part to find a sensible answer so I ask what do you expect to learn from me?

And a Star Destroyer is equipped with lasers so it wouldn't even penetrate the Enterprise's navigation shields.

The real question is just how much good will actually come from the increased CO2. CO2 is not pollution. Too many of us have allowed the warmies to create and dominate the narrative, therefore we hear CO2 and automatically think...oh crap that's bad. CO2 in fact has multiple life sustaining qualities. I'm not going to write a book here but google the benefits of increased CO2.

Oh no no no!!! Do NOT ask Sput to look anything up!

Starship Enterprise is outdated. Doesn't even have WiFi.


Radiation will not penetrate a perfect insulator, thus as I said space is not a perfect insulator.- Swan

The question is what is the total effects of a change is not just the good effects and ignoring the bad, that's dishonest. sure there seem to be a load of sites telling me how great CO2 is with pictures of trees but they all seem to be anti-environmentalist sites and not science sites like ;

http://www.plantsneedco2.org/default.aspx/MenuItemID/294/MenuGroup/BenefitsToHumans.htm

And taking a pedagogical tone telling me that something is not a pollutant is not productive. I know it has an effect thank you and changing the legal definition of a substance in a different country for the convenience of the current Junta in that country won't change that.

Well I think your sites are agenda driven also. So, that's a stalemate. What does some common sense tell you?

CO2 is plant food.

More vegetation good or bad?

More vegetation feeds more humans(crops, vegetables etc.) and animals.

More humans eat more animals. Warmies will tell you co2 and warmer will cause food shortages. Laughable.

I love steak.

How is this bad?

Don't blow off about upsetting the balance. God forbid then no one should ever plant a flower or vegetable garden. The only thing constant about the history of our earth is that it is always changing. We are simply a blip in history and to think we can change the climate is arrogance on display.

By the way, you have avoided my question all day. Don't want to talk about it?

WHAT IS MAN CONTRIBUTION TO TOTAL CO2 AND WHAT IS YOUR SOURCE?

The current episode of global warming is attributed to increasing emissions of CO2 and other greenhouse gases into Earth's atmosphere. The global annual mean concentration of CO2 in the atmosphere has increased by more than 40% since the start of the Industrial Revolution, from 280 ppm, the level it had for the last 10,000 years leading up to the mid-18th century

Why do you find it so hard to do three seconds of googling?

I try and use science websites who's agenda is science. For some breaking stories I use the media that breaks science news. your agenda seems to be to mislead.

I think that the increase in CO2 concentration cannot be totally due to man since evidently during the recovery from the last big ice age, the CO2 increased by itself.

Recovery from the ice age took thousands of years. man-made C02 power-up took 200+ years. & that is why AGW is dangerous. It is much more rapid that "natural" climate change, which is NOT weather.

Just wanted a number you think is good. So, is the above report a little "deceptive"?

You talk as if the "man-made CO2 power-up" has already happened. It has barely begun and we are just guessing with models where it is going and if it is dangerous.
