http://scifun.chem.wisc.edu/chemweek...bonDioxide.pdf Prof. Shakhashiri Science Is Fun in the Lab of Shakhashiri General Chemistry CARBON DIOXIDE, CO2 Carbon dioxide, CO2, is one of the gases in our atmosphere, being uniformly distributed over the earth's surface at a concentration of about 0.033% or 330 ppm. Commercially, CO2 finds uses as a refrigerant (dry ice is solid CO2), in beverage carbonation, and in fire extinguishers. Because the concentration of carbon dioxide in the atmosphere is low, it is not practical to obtain the gas by extracting it from air. Most commercial carbon dioxide is recovered as a by-product of other processes, such as the production of ethanol by fermentation and the manufacture of ammonia. Some CO2 is obtained from the combustion of coke or other carbon-containing fuels. C(coke) + O2(g) xxv CO2(g) Carbon dioxide is released into our atmosphere when carbon-containing fossil fuels such as oil, natural gas, and coal are burned in air. As a result of the tremendous world-wide consumption of such fossil fuels, the amount of CO2 in the atmosphere has increased over the past century, now rising at a rate of about 1 ppm per year. Major changes in global climate could result from a continued increase in CO2 concentration. In addition to being a component of the atmosphere, carbon dioxide also dissolves in the water of the oceans. At room temperature, the solubility of carbon dioxide is about 90 cm3 of CO2 per 100 mL of water. In aqueous solution, carbon dioxide exists in many forms. First, it simply dissolves. CO2(g) xxv CO2(aq) Then, an equilibrium is established between the dissolved CO2 and H2CO3, carbonic acid. CO2(aq) + H2O(l) øôõ H2CO3(aq) Only about 1% of the dissolved CO2 exists as H2CO3. Carbonic acid is a weak acid which dissociates in two steps. H2CO3 øôõ H+ + HCO3G Ka1 = 4.2 × 10G7 HCO3G øôõ H+ + CO3 2G Ka2 = 4.8 × 10G11 As carbon dioxide dissolves in sea water, an equilibrium is established involving the carbonate ion, CO3 2G. The carbonate anion interacts with cations in seawater. According to the solubility rules, “all carbonates are insoluble except those of ammonium and Group IA elements.” Therefore, the carbonate ions cause the precipitation of certain ions. For example, Ca2+ and Mg2+ ions precipitate from large bodies of water as carbonates. For CaCO3, the value of Ksp is 5 × 10G9, and for MgCO3, Ksp is 2 × 10G3. Extensive deposits of limestone (CaCO3) and dolomite (mixed CaCO3 and MgCO3) have been formed in this way. Calcium carbonate is also the main constituent of marble, chalk, pearls, coral reefs, and clam shells. Although “insoluble” in water, calcium carbonate dissolves in acidic solutions. The carbonate ion behaves as a Brønsted base. CaCO3(s) + 2 H+(aq) xxv Ca2+(aq) + H2CO3(aq) The aqueous carbonic acid dissociates, producing carbon dioxide gas. H2CO3(aq) xxv H2O(l) + CO2(g) In nature, surface water often becomes acidic because atmospheric CO2 dissolves in it. This acidic water can dissolve limestone: |

Using just the beginning of this which continues up to 2004.
TRENDS: ATMOSPHERIC CARBON DIOXIDE Atmospheric carbon dioxide record from Mauna Loa Graphics Digital Data C.D. Keeling and T.P. Whorf Carbon Dioxide Research Group, Scripps Institution of Oceanography, University of California, La Jolla, California 92093-0444, U.S.A. Period of Record 1958-2004 Methods Air samples at Mauna Loa are collected continuously from air intakes at the top of four 7-m towers and one 27-m tower. Four air samples are collected each hour for the purpose of determining the CO2 concentration. Determinations of CO2 are made by using a Siemens Ultramat 3 nondispersive infrared gas analyzer with a water vapor freeze trap. This analyzer registers the concentration of CO2 in a stream of air flowing at ~0.5 L/min. Every 30 minutes, the flow is replaced by a stream of calibrating gas or "working reference gas". In December 1983, CO2-in-N2 calibration gases were replaced with the currently used CO2-in-air calibration gases. These calibration gases and other reference gases are compared periodically to determine the instrument sensitivity and to check for possible contamination in the air-handling system. These reference gases are themselves calibrated against specific standard gases whose CO2 concentrations are determined manometrically. Greater details about the sampling methods at Mauna Loa are given in Keeling et al. (1982) and Keeling et al. (2002). Hourly averages of atmospheric CO2 concentration, wind speed, and wind direction are plotted as a basis for selecting data for further processing. Data are selected for periods of steady hourly data to within ~0.5 parts per million by volume (ppmv); at least six consecutive hours of steady data are required to form a daily average. Greater details about the data selection criteria used at Mauna Loa are given in Bacastow et al. (1985). And from the Energy Companies themselves, it covers from 2000 to 2008: CO2 Capture Project Trying to present both sides. |

Gosh I guess later come quicker than I thought. Using Climate Change as the search I found this, only 13 hours ago.
Climate change threatens human rights: UN - ABC News (Australian Broadcasting Corporation) Climate change threatens human rights: UN Posted Sat Mar 29, 2008 8:28pm AEDT The United Nations has officially declared that climate change is a threat to the human rights of people living in small island states. The UN Secretary-General Ban Ki-moon has said that tackling climate change is one of his top priorities, and now the UN Human Rights Council has made it official. I rest my point with the above....... If you would like to disagree I will still refute you. It is happening and that is the main fact... The resolution, which was passed unanimously in Geneva, recognises that climate change is not just a threat to the global environment and economy, but to life itself. Environmental experts say rising sea levels, violent storms, droughts and floods could all become more common because of global warming, and if they do, millions of people could be deprived of their homes, food and clean water.

The professor continued: "I am not denying global warming. For instance, Greenland, in the northern hemisphere, does seem to be going. But Greenland's ice cap - Greeland is quite far south - is a last survivor from the ice age and only its height protects it. The more that cap melts, the more it will continue to melt as it gets lower and warmer. But Antarctica is different. Even in the Arctic I am sceptical of some claims that 40 per cent of the sea ice has already vanished, and that what remains is drastically thinning.

This just in. And I remind each poster I don't care if humans or the period of time is the cause, but after several thousands of years of human activity one has to asume we have an effect,
Did anyone know of the little ice ages in the late 800 Ad or in 1450's AD. I might have the dates a bit off but the black plauge was during one of these periods. And this just in....... I am not looking at the reason to blame that is why I have presented both sides of the story. But this is real and affeting people right now........ Thai temple fights off encroaching tide as world sea levels rise by Charlie McDonald-Gibson Sun Mar 30, 12:47 PM ET Thai temple fights off encroaching tide as world sea levels rise - Yahoo! News KHUN SAMUT CHIN, Thailand (AFP) - Crabs scuttle across the wet floor of the near-deserted Khun Samut temple, the only building left in a Thai village that has disappeared beneath the rising and advancing sea. Waging a battle against an encroaching tide that has sent all the villagers fleeing inland, a monk in orange robes and faded tattoos meant to ward off evil spirits stalks the newly-built sea wall, planting mangrove shoots. Somnuek Atipanya points 20 metres (65 feet) out to sea, where electricity pylons poke out of the water, now useful only for resting marine birds. "The waves attacked here and they will destroy everything," says Somnuek, chief abbot of this Buddhist temple south of Bangkok which is surrounded by water and accessible only by a concrete walkway. "I don't know what happened, but when the experts came they told me it was global warning and melting ice in the North Pole." Over 30 years, the sea around Khun Samut Chin village has engulfed more than one kilometre (0.6 miles) of land, World Bank figures show, mostly because fishermen have cut down mangrove forests -- the Earth's natural sea barrier. Tourism development, sand mining and damming rivers upstream have also taken their toll in an area naturally prone to coastal erosion. The community have realised their errors and are trying to replant the mangroves, but the situation may soon be out of their hands as global warming sends sea levels rising and powerful storms lashing the coast. "The process has been occurring over some time and accelerating with land use changes and local human activity," says Jitendra Shah, the World Bank's environmental coordinator in Thailand. "Climate change impacts are likely to accelerate the pace and make things worse in the future." Coastal erosion of varying degrees affects 21 percent of Thailand's coastline, says Greenpeace climate campaigner Tara Buakamsri, citing figures from Bangkok's Chulalongkorn University. Along the Gulf of Thailand, seaside areas seriously affected by erosion are receding at a rate of five to 20 metres per year. Climate scientists say that as global warming heats the Earth up, glaciers and polar ice caps will melt and sea waters will expand, sending oceans rising by at least 18 centimetres (7.2 inches), or possibly a great deal more by 2100. World sea levels rose 3.1 millimetres per year from 1993 to 2003, the Nobel-winning Intergovernmental Panel on Climate Change (IPCC) says. This is not good news for the five monks who remain at Khun Samut temple. Despite their best efforts, they may not be able to save the site from the same fate that befell Khun Samut Chin's sunken school and homes. Visanu Kengsamut, 26, has already moved three times in his life, while his mother -- the village chief -- has fled the crumbling coast and rebuilt her home eight times, and each time the village has paid for its own relocation. Khun Samut Chin now sits about one kilometre inland from the temple. "We know that the cause of this is the effects of global warming," says Visanu. "This problem, everybody should take responsibility and the government should help. If possible, the international community should come to help because they started the problem." As the world tries to work out a new pact to battle the threat posed by global warming, poorer countries -- who the IPCC says will suffer the most from climate change -- are battling to have their voices heard. They argue that because the industrialised world was historically most responsible for global warming, they should contribute generously to a fund to help poor countries adapt to the changing world. The so-called adaptation and mitigation fund will likely be discussed at key United Nations climate change talks in Bangkok from March 31 to April 4. "Whether or not it is a small contribution or major contribution related to climate change in the past, this community needs to be taken into account when they discuss about the mitigation measure or adaptation fund," says Greenpeace's Tara. "Because they are facing the impact -- they are one of the first groups in Thailand that is facing the impact." |

One can't refute the truth when it is plainly placed in their face, right.
The issue isn't why but what the **** do we do now that it is happening! To debate that man hasn't a hand in it isn't wise. It is how do we stop the expanding economies and our selves from making the train go faster. Well that is IMHO..........:-) And besides the poll is double for man has a hand in it. So twice as many believe we have something to do with it. Just like the science on the topic. And I tried to present both sides. Just there wasn't much to say we aren't part of the problem. I put each page and all the searchs I used for each post. I don't care to bother reading over 2 million pages when if I say man had nothing to do with it only 50,000 or less would support that idea. I do thank each for their thoughts and expressing themselves. I never started to defeat any person. I just believe in posting the truth in all topics. And being an old warrior I can't give up on anything, period. I only know one way forward, fix bayonets and forward. lol Last edited by mlurp; 04-01-2008 at 09:20 PM. |

I'v seen things on History, HGC or some other channel, the same kind of reports and let downs as we discover so much these days. But the war gets it's almighy inflated dollar... lol
