CO2 Level at Least 800,000-Year High!
According to the Earth System Research Laboratory of the US National Oceanic & Atmospheric Administration, the May monthly mean CO2 concentration measured at Mauna Loa was 389.47 ppmv. This is a new maximum for this data set, the longest term and most frequently referenced CO2 data. Also, according to the IPCC WG1 AR4 list of robust findings: "Current atmospheric concentrations of CO2 and CH4, and their associated positive radiative forcing, far exceed those determined from ice core measurements spanning the last 650,000 years." The EPICA Dome C record extends this to 800,000 years. Please see data from Lüthi, D et al. (2008) at http://doi.pangaea.de/10.1594/PANGAE...01?format=html For a graph and curve fit of data taken at Mauna Loa, please see: http://members.cox.net/rcoppock/CO2-6DegreesFreedom.jpg Clearly, the atmospheric CO2 concentration is rising exponentially. To see this, compare the trend of the red colored points on the graph I have provided with a straight line. =-=-=-=-=-=-=-=-= These data may be found at: ftp://ftp.cmdl.noaa.gov/ccg/co2/trends/co2_mm_mlo.txt The yearly means of the 607 points of monthly data follow: YEAR CO2_ppmv 1958 315.33 8 months of data 1959 315.98 1960 316.91 1961 317.64 1962 318.45 1963 318.99 1964 319.20 9 months of data 1965 320.04 1966 321.38 1967 322.16 1968 323.04 1969 324.62 1970 325.68 1971 326.32 1972 327.45 1973 329.68 1974 330.17 1975 331.13 11 months of data 1976 332.05 1977 333.78 1978 335.41 1979 336.78 1980 338.68 1981 340.11 1982 341.22 1983 342.84 1984 344.22 11 months of data 1985 345.87 1986 347.19 1987 348.98 1988 351.45 1989 352.90 1990 354.16 1991 355.48 1992 356.27 1993 356.95 1994 358.64 1995 360.63 1996 362.37 1997 363.47 1998 366.50 1999 368.14 2000 369.40 2001 371.07 2002 373.17 2003 375.78 2004 377.52 2005 379.76 2006 381.85 2007 383.71 2008 385.57 2009 388.15 4 months of data [Watch the fossil fools dust off an ancient archive of pseudo-science and arcane mathematics in a lame attempt to challenge these basic facts.

But even then, 800,000 years ago the levels were higher then today. This chart is based on "GEOCARB III (Berner and Kothavala 2001), COPSE (Bergmann et al. 2004) and Rothman (2001).

We are about 30% higher then about 100 - 150 years ago, but it has been almost 600 % higher then now about 110 million years ago. More then 2000 ppmv, compared to about 385 today. And even much higher then that 500 million years ago. On that scale, CO2 level today is at the bottom of the chart... I guess that is why some people say that the Earth today is CO2 starved. Nope, I won't lose any sleep. This is just more Gorebull Warming "Let's Scare The People" Alarmism |

Your maths is wrong. 2000ppmv is only 415% higher than now not 600%. But why is this relevant? 110 mya is way before the first humans or even the first apes. It's 55mya prior to the PETM which is 55mya earlier than today, which episode wiped out much of life on Earth. Nobody was affected because nobody existed. And even much higher then that 500 million years ago. And even less relevant. This was before the carboniferous era. What is your point? On that scale, CO2 level today is at the bottom of the chart... Why is this relevant to pronouncing on the pertinence of CO2 to human wellbeing. There were not 6.5 billion humans 500 million or 110 million years ago. I guess that is why some people say that the Earth today is CO2 starved. I rarely hear people saying this, and those who do are either dissembling or are ignorant and unthinking. Fran |

So far neither IPCC nor has anyone else provide one iota of valid data for global warming nor have they provided data that climate change is being effected by commerce and industry, and not by natural phenomena. Yes, atmosphereic CO2 is indeed monitored from the largest active volcanoe in the world. Not what I would think to be the brightest idea. What they say they try to do, is to make adjustments for out- gassing of CO2 from the volcanoe. How well they are able to do that, how they do it, and how precise their adjusments are, I'm not sure. There should certainly be questions asked and answered. In my opinion, there are far better places in the world to measure atmospheric CO2 then the top of an active volcanoe which belches that very gas from the crater and several vents and cones and the occasional lava flow. What bright mind came up with that location ? And who were the bright minds that agreed to it? |

Higher than that could be scary. Let's not shoot for it, ay? Lee |

I don't know how we could do that and don't see any reason for trying. *No or very little life on Earth... *it's vital... And some people are now labelling it pollution... False dichotomy. The fact that it is vital to life on Earth doesn't mean it can't also be a pollutant. Years ago a small (trace amount) of copper and zinc used to leach into urban water supplies from pipes. Copper and zinc are micronutrients. In extreme cases you can die from lack of zinc and copper so it's essential to life and certainly to health, so this 'pollution' was a good thing. OTOH if a lot more had got into the water lots of people would have become quite ill and some would have died. So copper and zinc are essential to life and also pollutants. Likewise going out into the sun for 20 minutes each day and exposing your arms, legs and face is a good way of avoiding rickets because your body builds vitamin D from fats. Over exposure can cause melanoma however. What a crazy world we live in where we have to see components of our environment much as goldilocks saw hers. * *CO2 is almost as low as it ever has been to the best of our knowledge.... * so I see no cause for alarm at all. Non sequitur. You're assuming ceteris paribus -- that all else is equal, but all else is not. There are now 6.5 billion people on the planet rather than zero. We depend on the ecosystem not changing very much because even a small change in the avalable arable or industrial land or its distribution or its yields or the availability of residential land would cause massive dislocation and misery. The continents weren't then where they are now and sea levels were far higher then than now and as we know each of these periods of high CO2 marked one of the five major extinction events recorded in the record. The End Permian event wiped out pretty much all higher order life on the planet. The fact is though that each of the past events was marked by slower rises in CO2 concentration than today's (although the PETM was fairly close). The other problem with your claim is that we are not now at the ceiling. Thwere is simply no basis for thinking that absent human intervention, CO2 concentrations will stabilise. We are entitled to think that if your side get their way the planet will have concentratuions of 1000-1200 ppmv by the end of the 21st century which would be a much faster rise than in the PETM. How do you suppose that will affect biodiversity? What would such concentrations do to the pH of the sea? The stability of the permafrost and its trapped CH4? The health of marine phytoplankton which are themselves a major CO2 sink? How will the humans of 2200 onwards cope with that, do you suppose? This is one of the problems with your crowd. You are thinking about your creature comforts NOW but are indifferent to the mess you will leave those who follow us and so speak as if our obligation is at most to the next 5-10 years. That's simply reckless. * *I would like to make another point if I may,,, *that in the original post by our dear friend Roger Coppock, the statement that the level of CO2 in the atmosphere now reaching the level that it was 800,000 years ago is very badly in error, if it is not an outright lie. You can make that point, but until you come up with some evidence nobody serious will believe you. Fran |
