Claims about CO2 

 What are the CO2 arguments? 

 CO2 emissions do not correlate with CO2 concentration 

 That humans are causing the rise in atmospheric CO2 is confirmed by multiple isotopic analyses. 

 http://www.skepticalscience.com/CO2-emissions-correlation-with-CO2-concentration.htm 

 It is easily demonstrated that there is no correlation between CO2 emissions and atmospheric CO2 concentration.

 There's no correlation between CO2 and temperature 

 With 32 years of rapidly increasing global temperatures and only a minor increase in global CO2 emissions, followed by 33 years of slowly cooling global temperatures with rapid increases in global CO2 emissions, it was deceitful for the IPCC to claim that CO2 emissions were primarily responsible for 20th century warming

 There is long-term correlation between CO2 and global temperature; other effects are short-term

 CO2 has a short residence time 

 overwhelming majority of peer-reviewed studies (and corroborating empirical measurements) finding that CO2 in the atmosphere remained there a short time

 Excess CO2 from human emissions has a long residence time of over 100 years

 CO2 measurements are suspect 

 Mauna Loa is a volcano and it doesn’t seem to me that a volcano is the best place to be taking CO2 measurements 

 http://disinter.wordpress.com/2007/08/01/more-on-the-global-warming-hoax/ 

 CO2 levels are measured by hundreds of stations across the globe, all reporting the same trend.

 CO2 is coming from the ocean 

 The rising values of atmospheric carbon dioxide during the time of the Mouna Loa measurements could clearly be a function of reduced solubility of CO2 in the oceans of the Planet. 

 http://wattsupwiththat.com/2007/11/04/guest-weblog-co2-variation-by-jim-goodridge-former-california-state-climatologist/ 

 The ocean is absorbing massive amounts of CO2, and is becoming more acidic as a result.

 CO2 was higher in the late Ordovician 

  the Late Ordovician Period was also an Ice Age while at the same time CO2 concentrations then were nearly 12 times higher than today

 The sun was much cooler during the Ordovician

 CO2 is not a pollutant 

 To suddenly label CO2 as a "pollutant" is a disservice to a gas that has played an enormous role in the development and sustainability of all life on this wonderful Earth. Mother Earth has clearly ruled that CO2 is not a pollutant. 

 http://www.populartechnology.net/2008/11/carbon-dioxide-co2-is-not-pollution.html 

 Excess CO2 emissions will lead to hotter conditions that will stress and even kill crops

 CO2 effect is weak 

 The strong CO2 effect has been observed by many different measurements 

 http://www.skepticalscience.com/empirical-evidence-for-co2-enhanced-greenhouse-effect.htm 

 minor green house gases such as CO2 have little effect 

 http://www.oism.org/pproject/s33p36.htm 

 Warming causes CO2 rise 

 Differentiating the CO2 measurements over the last thirty years produces a pattern that matches the temperature anomaly measured by satellites in extreme detail. 

 http://wattsupwiththat.com/2010/06/09/a-study-the-temperature-rise-has-caused-the-co2-increase-not-the-other-way-around/ 

 Recent warming is due to rising CO2. 

 http://www.skepticalscience.com/warming-co2-rise.htm 

 CO2 was higher in the past 

  If the IPCC theory is correct there should have been runaway greenhouse induced global warming during the Ordovician-Silurian and Jurassic-Cretaceous periods but instead there was glaciation.

 When CO2 was higher in the past, the sun was cooler 

 http://www.skepticalscience.com/co2-higher-in-past.htm 

 CO2 effect is saturated 

 Each unit of CO2 you put into the atmosphere has less and less of a warming impact. Once the atmosphere reaches a saturation point, additional input of CO2 will not really have any major impact.  

 http://viewhigh.blogspot.com/2007/08/is-earth-really-warming-part-2.html 

 Direct measurements find that rising CO2 is trapping more heat

 CO2 is not increasing 

 CO2 is increasing rapidly, and is reaching levels not seen on the earth for millions of years 

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

  carbon dioxide levels in the atmosphere are about where they were 160 years ago

 CO2 lags temperature 

 An article in Science magazine illustrated that a rise in carbon dioxide did not precede a rise in temperatures, but actually lagged behind temperature rises by 200 to 1000 years.  

 http://joebarton.house.gov/Issues.aspx?Section=52 

 Recent CO2 increase has caused recent warming without any time lag.
