Not to mention the fact that it would probably accelerate plant growth rates (and in fact such acceleration would prevent the levels from ever getting that high). I remember reading a study somewhere that plant growth doesn't accelerate that much with increasing CO2 concentration. It is a factor that can slow down global warming slightly, but not much. I don't have references. Also, 1-3.5 degrees C is equal to 150 to 550 kilometers of distance towards the equator - trees can have trouble adjusting and might get massive disease outbreaks. This has happened somewhat in northern areas when some parasites' larvae don't die anymore since the winters tend to be warmer than before. Actually, I've read that human activity is causing the sixth mass extinction as we speak. |

Not to mention the fact that it would probably accelerate plant growth rates (and in fact such acceleration would prevent the levels from ever getting that high). Valid point. I read somewhere that the equalization point is around 600 ppm. Still not a good number though. Another interesting poing is that I keep seeing people whine about methane. They say that it is something stupid like 40x as potent a ghg. Methane in the atmosphere has a 5 year half-life. so in order to keep the levels high, you have to continually release. Methane has a shorter lifespan in the atmosphere, but is more potent at retaining heat in the atmosphere than is CO2. In addition, it breaks down to CO2, and so increases the CO2 levels as well.

Don't listen to the borg, get the facts : "Methane has an atmospheric lifetime of 12 +/- 3 years and a GWP of 62 over 20 years, 23 over 100 years and 7 over 500 years. The decrease in GWP associated with longer times is associated with the fact that the methane is degraded to water and CO2 by chemical reactions in the atmosphere." http://cosmic.lifeform.org Okay, I was wrong by a small amount in my half-life statement, I read it last year. However, Your citation is also wrong. the proportion of the methane which degrades to co2 remains in the atmosphere for milennia, correct, but the water vapor precipitates out. And then evaporates back into the atmosphere. The call it the hydrologic cycle. It is a continuous cycle. George |

It's no coincidence that AGW'er and eco-nut Coby Beck is apparently a
racist ("All the general depictions of poor black people as dangerous animals were wrong" [trying ironically to be sarcastic, but exposing his racism). It's no coincidence because AGW'ers, like CB and NobodyYouKnow, are in fact camouflaged racists, intent on stopping human growth, for such trivial things as keeping their property values high (as if letting it a little colour into their neighborhood would diminish property values--it would not in fact), and maintaining their uncongested views. Yep, this is the ugly face of the GW agenda. RL |

Well said Bill. I live and travel in Europe as well as the US, and
they are definitely more energy efficient. Increasing the price of fossil fuels will indeed stimulate alternative fuels and help balance the federal budget deficit. But I am against caving in to the Eco-Nuts and to signing hapless Kyoto treaty. RL |

Oh, I think the plants and 100,000 head of cattle that have just dies in the Texas wildfires would complain. You forgot to mention 11 humans. The plant life will naturally recover, and the life of cattle is usually cut short anyway and seen as t-bones, rump roasts or on special occasions, as cow tongue. Naturally, there could also be a loose association with many of the meteorological disasters over the past 20 years, but still it's a small price to pay compared to the benefits. More obvious would be a temporary increase in cost of beef due to the sheer loss. Harsher weather than we've already seen is inevitable, but it's temporary and will settle into calmer weather once temperatures stabilize from north to south. -- Listed?

Hello,
These high levels may be survivable but the "escape" reflex occurs at a much much lower level. A feeling of suffocation and the desire to escape to "fresh air" occus at around 400 ppm and I feel like that all the time and there is no fresh air. My respiration frequency has increased to double previously and I feel I cannot get my breath, I've noticed quite a lot of older people are having the same difficulty. I have not been diagnosed with lung disease or reduced lung area. Some days are better than others, today it is like that, called "oppressive". I think the whole human race is close to suffocation. My own opinion is that government agencies need to build nuclear powered carbon dioxide splitters to take in atmospheric carbon dioxide and spit out soot and oxygen. We must all give up burning carbon based fuels and transfer to other forms of power and a business must develop fusion power as quickly as posible. My suggestion is in my web site at http://www.newelectricity.co.uk/ Recently a friend announced success of her fusion reactor and was quickly captured and within a week or two she was publicly "executed" by removal of her frontal lobe. She had plenty of capital and was already running a succesful business and I cannot understand why she was assaulted it seems the world is mad. The psychiatrists said her ideas were "Sky High" and had no understanding of her machines although she had a PhD. I mean, what has happened to the world, don't the people in power want the stuff? She also had a plan for a "thinking" computer (they just said "computers can't think!"). Now she just sits and stares. -- Chris |
