Kittens too!

Uhhh, no. But show me a Republican candidate that isn't also a corporatist...HEARTLESS wrote: So Obama is just another lying corporatist and that is reason to vote for his lies and failures again. Brilliant!

The primary contributor to the atmosphere is absolutely not volcanic sources. Take one look at the graph of CO2 measurements estimated from ice cores compared to direct measurements (1st graph), and taken directly at Mauna Loa by itself (2nd graph, sorry I can't blow it up anymore than it is) for the last 40+ years (the Keeling curve), and correlate that to volcanic eruptions - doesn't compute. As to other natural sources, yes they are adding as well, but when you consider that land use is one of them, and how we've re-shaped the land (clear-cutting, building cities, farms, etc), then that makes us the cause, not really the land.HEARTLESS wrote: SC, did you watch the videos on page 42 (Doctors for Disaster Preparedness 2010 conference) from the Severe trouble ahead... thread? If not, please do as the speakers give good reason to not believe in AGW. If carbon is even a cause of the warming, the primary contributor to it in our atmosphere is volcanic and other naturally occurring sources, not mankind. The videos are long at one hour each but give sound reasoning for their stance.
Vulcanism
Emissions of CO2 due to volcanic activity, though sometimes large on a local scale, are relatively minor on a global scale, accounting for between 0.02 and 0.05 Pg C per year.
Land-use Change
Current estimates suggest land-use changes lead to the emission of 1.7 Pg C per year in the tropics, mainly as a result of deforestation, and to a small amount of uptake (about 0.1 Pg C) in temperate and boreal areas - so producing a net source of around 1.6 Pg C per year.
Energy - Stationary Sources
Of the carbon dioxide emissions arising from fossil fuel combustion—up to 6.5 Pg C each year—around 40% is a result of electricity generation, with coal-fired generation being the leading sector. Other stationary sources include industrial (particularly iron and steel manufacture), emissions resulting from oil extraction, refinement and transportation, and domestic and commercial fossil fuel use.
Energy - Mobile Sources
They currently consitute around 24% of anthropogenic CO2 emissions. Road transport dominates these emissions, though off-road, air and marine transport emissions are aslo significant. The use of petroleum as a fossil fuel for transportation dominates carbon dioxide emissions from this source. In 1999, in the U. S., more than 30 percent of fossil fuel-related carbon dioxide emissions were a direct result of transportation. With about two-thirds of this being from gasoline consumption by motor vehicles and the remainder coming from diesel and jet fuel use in lorries and aircraft, respectively.
Industry (non-energy-related)
The final amount of CO2 produced varies depending the type of cement being made. Globally, this source is estimated to amount to 0.2 Pg C emission to the atmosphere each year. Significant carbon dioxide emissions (around 0.25 PgC per year) also result from its use in chemical feedstocks.
Biomass Burning
Though responsible for large CO2 emissions over short time-scales, the net CO2 emissions due to biomass burning are difficult to quantify due to the subsequent uptake of CO2 through regrowth of vegetation. An unsustainable (i.e., not off-set by regrowth) fraction equivalent to about 10% of total emissions is generally assumed biomass used in energy-generation, with this figure being incorporated into the total emissions resulting from land-use change.
Yes, it is, unequivocably, and the paper that established that was published in 1896 - before computers, calculators, and AGW confusion and delay campaign being waged by vested interests and being used as a political hot potato. The link to his paper is in the Wikipedia reference if you care to read it yourself. http://www.aip.org/history/climate/co2.htm and http://en.wikipedia.org/wiki/History_of ... ge_scienceIf carbon is even a cause of the warming
