http://www.jpl.nasa.gov/news/news.cfm?release=2008-189 This is an interesting map that shows how different parts of the earth can have different CO2 concentrations. They did say: "The zonal flow of the southern hemisphere mid-latitude jet stream results in a belt of enhanced carbon dioxide girdling the globe, fed by biogenesis activity in South America, forest fires in both South America and Central Africa, and the clusters of gasification plants in South Africa and power generation in southeastern Australia." No mention of automobiles and CO2. It would be nice if they could identify additional sources or have a daily map for each day of the year. Add in other green house gases and we would certainly get a better understanding of climate change. |

Replying to: gagrice (Oct 15, 2008 7:58 pm) As the evidence for global warming and a man made influence grows your argument or your words do not look all that logical or rational. Attacking these people is of little value and will likely backfire. Saying that scientists have little integrity is just false. I am a scientist and I have worked with a lot of scientists and engineers. They are people just like a business man or an artist. Maybe you have been watching to many science fiction movies with mad scientists in them. And just for the record, I have never falsified data. I work at a place where we can tell it like it is. Vehicles do contribute to global warming. How much and what we should do about it is another story. I suspect that China, India and the Middle Eastern countries will decide how high CO2 levels go. Maybe you should go to a conference on GW and meet the scientists. I doubt you would ever do that because then you would find there is logic to their research and that they do have a great deal of integrity.

Replying to: avalon02wh (Oct 17, 2008 3:45 am)  . If you want to list a real case, where all the most "treasured" institutions let the CA taxpayer down: we need only go to the CA state process of certifiying MTBE and the ultimate and continuing fiasco. Many, many, many, scientists (among the other interested/disinterested, etc parties that Gagrice refers to) gave what is ultimately called a "neg dec," aka negative declaration. This is all in the CA state public record, (as most other states proceedings are). You can verify/discredit easily what I have been saying.

Replying to: avalon02wh (Oct 17, 2008 3:45 am) Do you mean like the UN conference in Bali, where scientists with opposing viewpoints were not invited or blocked from attending? I have no doubt that much of the science surrounding the GW/CC is legitimate. When the politicians take it and pull out what they want to use, then claim a consensus, all that scientific evidence becomes suspect. Vehicles do contribute to global warming. How much and what we should do about it is another story Possibly so. Livestock, volcanoes, burning of land to grow corn, sugar and soybeans all emit GHG. And I believe the SUN may play a part in all this climate change. Maybe you have been watching to many science fiction movies with mad scientists in them. I did not see "An Inconvenient Truth".

Replying to: gagrice (Oct 17, 2008 6:48 am) If it bears out I think we can probably forget worrying about CO2 emissions from cars. We're - possibly - doomed regardless. Will the Earth miss us ? Not even slightly. Enjoy.  METHANE AS GHG

Replying to: alltorque (Oct 17, 2008 7:57 am) We work hard to dis- acknowledge GOD, yet attribute god like powers to an ICE.!!!????  Bas ackwards if you axe me, but that is my unscientific .02 cents. Scientifically? Well... ya got to play the game if you want to remain in the career!!???

Someone better find out what is causing this or the Polar Bear, reindeer, and caribou are doomed..........: Arctic Glowing Red Arctic air temperatures climb to record levels Thu Oct 16, 2008 6:01pm EDT WASHINGTON (Reuters) - Fall air temperatures have climbed to record levels in the Arctic due to major losses of sea ice as the region suffers more effects from a warming trend dating back decades, a report released on Thursday showed. The annual report issued by researchers at the U.S. National Oceanic and Atmospheric Administration and other experts is the latest to paint a dire picture of the impact of climate change in the Arctic. It found that fall air temperatures are at a record 9 degrees Fahrenheit (5 degrees C) above normal in the Arctic because of the major loss of sea ice in recent years that allows more solar heating of the ocean. That warming of the air and ocean impacts land and marine life and cuts the amount of winter sea ice that lasts into the following summer, according to the report. In addition, wild reindeer and caribou herds appear to be declining in numbers, according to the report. The report also noted melting of surface ice in Greenland. "Changes in the Arctic show a domino effect from multiple causes more clearly than in other regions," James Overland, an oceanographer at NOAA's Pacific Marine Environmental Laboratory in Seattle one of the authors of the report, said in a statement. "It's a sensitive system and often reflects changes in relatively fast and dramatic ways." Researchers at the National Snow and Ice Data Center, part of the University of Colorado, reported last month that Arctic sea ice melted to its second-lowest level this summer. The 2008 season, those researchers said, strongly reinforces a 30-year downward trend in Arctic ice extent -- 34 percent below the long-term average from 1979 to 2000, but 9 percent above the record low set in 2007.
