The conclusions in this statement reflect the scientific consensus represented by, for example, the Intergovernmental Panel on Climate Change, and the joint National Academies' statement. For more information, see the AAAS Global Climate-Change Resources page. American Association for the Advancement of Science AAAS Board Releases New Statement on Climate Change --------------------------------------------------- - 18 February 2007 - The scientific evidence is clear: global climate change caused by human activities is occurring now, and it is a growing threat to society. Accumulating data from across the globe reveal a wide array of effects: rapidly melting glaciers, destabilization of major ice sheets, increases in extreme weather, rising sea level, shifts in species ranges, and more. The pace of change and the evidence of harm have increased markedly over the last five years. The time to control greenhouse gas emissions is now. The atmospheric concentration of carbon dioxide, a critical greenhouse gas, is higher than it has been for at least 650,000 years. The average temperature of the Earth is heading for levels not experienced for millions of years. Scientific predictions of the impacts of increasing atmospheric concentrations of greenhouse gases from fossil fuels and deforestation match observed changes. As expected, intensification of droughts, heat waves, floods, wildfires, and severe storms is occurring, with a mounting toll on vulnerable ecosystems and societies. These events are early warning signs of even more devastating damage to come, some of which will be irreversible. Delaying action to address climate change will increase the environmental and societal consequences as well as the costs. The longer we wait to tackle climate change, the harder and more expensive the task will be. History provides many examples of society confronting grave threats by mobilizing knowledge and promoting innovation. We need an aggressive research, development and deployment effort to transform the existing and future energy systems of the world away from technologies that emit greenhouse gases. Developing clean energy technologies will provide economic opportunities and ensure future energy supplies. In addition to rapidly reducing greenhouse gas emissions, it is essential that we develop strategies to adapt to ongoing changes and make communities more resilient to future changes. The growing torrent of information presents a clear message: we are already experiencing global climate change. It is time to muster the political will for concerted action. Stronger leadership at all levels is needed. The time is now. We must rise to the challenge. We owe this to future generations. -- The American Association for the Advancement of Science, "Triple A-S" (AAAS), is an international non-profit organization dedicated to advancing science around the world by serving as an educator, leader, spokesperson and professional association. In addition to organizing membership activities, AAAS publishes the journal Science, as well as many scientific newsletters, books and reports, and spearheads programs that raise the bar of understanding for science worldwide. |

![]() "Retief" wrote Liar. CO2 was up substantially by this time. Well, 6 percent. Now up an additional 28% since 1900 "Retief" wrote Curiously it failed to produce any measurable warming until about 1920. Actually it failed to produce any attributable warming until the early to mid 1980's. But you are quite correct. The globe is warming as a result of the higher levels of CO2 in the atmosphere. Did you actually intend to admit that? |

![]() "Retief" wrote in message The CO2 IR bands were saturated at pre-industrial concentrations. Which is another lie on your part. As the atmosphere thins with altitude, it necessarily becomes more transparent to IR and all other forms of light. Hence your claim that the "bands are saturated" only has meaning at a specific altitude, since at higher altitudes the bands can not be saturated. Further, saturation is also thickness dependent. Is the band saturated over 1 cm of air the air column, or 2 cm or 3 cm? 1 mile? Through the entire atmosphere? Ahahahah Stupid.. Stupid.. Retief. If there is saturation over a thickness of 1 cm then one can expect 100% absorption over a depth of 1 cm. and a mean free path of X cm. However if there is saturation over a thickness of 2 cm then the mean free path is 2X cm, and on average the light will travel twice the distance as before, before it has a 50% chance of being scattered in a downward direction. If the bands are saturated and the mean free path is 2X cm then heat will leak out of a given thickness twice as fast as it would if the bands were saturated and the mean free path were X cm. So having the absorption bands saturated means little to nothing, but it probably does impress the Scientifically illiterate such as yourself, and those who know better and continue to lie about the ramifications - like those from whom you got your little snippit of propanda. The more CO2 you have, the more backscatter you have and the more backscatter you have. the longer it takes for the heat to radiate to higher altitudes, and therefore the greater the heating at lower altitudes. Stupid... Dishonest Retief.... Can't fathom even basic high school science. Moron... Further, water competes CO2 over the IR spectra -- to the point that in an atmosphere containing water, doubling of CO2 results in negligible absorption increase... Did you actually intend to admit that? Scott Nudds, as usual, promotes his lies and strawmen. Retief |
