Henry, I suggest you learn about it instead of listening to morons pretending to know about CO2's effects. http://www.am.ub.es/~jmiralda/fsgw/lect3.html The radiative forcing from each greenhouse gas The importance of each greenhouse gas for climate is measured by its contribution to the radiative forcing . What is radiative forcing? Radiative forcing is the amount by which a variation in the abundance of a greenhouse gas, compared to its abundance in pre-industrial times, changes the radiation energy budget of the Earth, if we change the abundance of the greenhouse gas but we do not alter the temperature and other properties of the surface and the troposphere. For example, we know from our energy budget diagram in page 17 that the surface emits 114% of the incoming solar energy. This is 342x1.14 = 390 Watts per square meter. But because the atmosphere absorbs some infrared radiation, only 69%, or 342x0.69 = 237 Watts per square meter are actually emitted to space. If we now increase the abundance of carbon dioxide, the atmosphere becomes more opaque and even less infrared energy is emitted to space. For the case of the increase of carbon dioxide from 270 ppmv in pre-industrial times to 370 ppmv today, the outgoing infrared energy is reduced by 1.5 Watts per square. So the change in carbon dioxide has produced a radiative forcing of 1.5 Watts per square meter. The radiative forcings have been calculated for all the greenhouse gases as a function of their abundance. These calculations are done by computing the way the radiation at each wavelength is absorbed and reradiated at different layers in the atmosphere, until it escapes to space. The present radiative forcings of each greenhouse gas (compared to their greenhouse effects in pre-industrial times) a Carbon dioxide: 1.5 Watts per square meter. Methane: 0.5 Watts per square meter. Nitrous oxide: 0.2 Watts per square meter. Halocarbons: 0.2 Watts per square meter. Total from all greenhouse gases: 2.4 Watts per square meter. Hence, at present carbon dioxide is responsible for 60% of the anthropogenic greenhouse effect, methane is responsible for 20%, nitrous oxide for 10%, and halocarbons for 10%. The total radiative forcing of 2.4 Watts per square meter is equivalent to 1% of all the energy absorbed from sunlight in the surface and atmosphere of the Earth, at present, and it will increase as greenhouse gas abundances increase in the future. In more popular physical units, the total radiative forcing is 10000 Watts for every acre of land or ocean in the Earth. This means that, if you take an acre of land or ocean anywhere in the Earth, the present anthropogenic greenhouse effect results in warming that is equivalent to what we would get if we had an electric heater of 10000 Watts turned on all the time, warming the surface and the air near the surface. The calculations of the total radiative forcing from anthropogenic greenhouse gas has been determined to be accurate to 10%. Any errors in our knowledge of the absorption properties of the molecules or their distribution in the atmosphere could change the total radiative forcing only in the range between 2.2 and 2.7 Watts per square meter. |

Got the short shrift very quickly when the farmers got ****y http://www.scoop.co.nz/stories/HL0309/S00040.htm The question is - what result did that have? the legislation never got passed, no tax = happy farmers but man, do we (as a country) produce a lot of greenhouse gases!
