Will the real John Christy please stand up??
--------------------------------------------------------------------- From the Himalayas to the South Pacific, 'Climate Witnesses' Testify About Global Warming The Associated Press Dec. 10, 2004 - A Nepalese Sherpa fears his mountain valley will be flooded by melting glacier runoff high in the Himalayas. A Fiji islander frets about rising sea levels, while villagers cope with the destruction of mangrove swamps in India. As scientists debate whether global warming is affecting Earth, "climate witnesses" told a U.N. environmental conference Friday they are already feeling the heat of the changing weather patterns they say are drastically affecting the way of life from the Himalayas to the South Pacific. "In the past we just accepted it was the will of God," said Penina Moce, a woman from Udu, a fishing village in Fiji. "But now we believe there could be other reasons." Moce spoke as delegates from nearly 200 countries sat down in Buenos Aires for an annual gathering by government officials, scientists, and environmentalists aimed at trying to reduce "greenhouse" emissions believed by many to be causing a rise in Earth's temperatures. The 44-year-year-old mother of five said many on her South Pacific island of 400 people are alarmed by recent signs of altering climate: shortened rainy seasons, eroding coastlines and dwindling fish stocks. Water, already in short supply, has become even harder to come by, she said. "When it rains, everyone will leave whatever they're doing and rush outside to try and save as much water as possible," she said. "We are lucky if it rains for two days straight." Environmentalists say her testimony exemplifies what is occurring in some areas affected by global warming and climate change issues the world has tried to address through the Kyoto Protocol, an agreement requiring initial cuts in "greenhouse gas" emissions by 2012 that comes into force in February. With only a few months remaining before Kyoto takes effect, the science over global warming remains divided. The United States the largest industrialized country not to join the treaty has cited scientific uncertainties as one of the reasons. Debate has dragged on for decades over the causes of climate change and whether it is already being felt. Many scientists believe carbon dioxide and other greenhouse gases released by factories, vehicles and coal-burning power plants seriously threaten life on Earth by causing a gradual rise in the planet's temperature. Global warming has been blamed for more violent storms, rising sea levels and shrinking animal habitats. Caspar Ammann, a scientist and climatologist with the National Center for Atmospheric Research in Boulder, Colo., said changes are apparent around the world. "You see the massive changes in the mountain ranges around the world. Where you see the glaciers disappearing very rapidly, you see changes in vegetation and changes in the whole seasonal cycles. The sea ice that is going back ... these are indications." A study by Tom Wigley and Sarah Raper of the Climatic Research Unit in Britain found a 90 percent probability global temperatures will rise 3.1 to 8.9 degrees between 1990 and 2100 as a result of human influences if greenhouse gas emissions continue unchecked. Other experts disagree, saying Earth's temperatures have varied greatly over time, and little is known about how the atmosphere copes with temperature change. "If you look at the long-term records of temperatures, you will see periods warmer than today and periods colder than today," said John Cristy, a climatologist at the University of Alabama. "We don't see the same warming in the deep atmosphere," he said. "If it were man-made, that's where you would see the warming." ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ^^^^^^^^^^^^^^^^^^^^^^^^^^ But Anil Krishna Mistry, a 37-year-old rice farmer living in mangrove swamps along India's border with Bangladesh, said he is worried by what he sees as changing climate patterns. He said the region is under constant threat of flooding from heavy rains and that rising sea levels have washed away huge tracts of land and made others too salty for rice growing. "There were 64 types of mangrove plants in the region, but now half of those species are dying out," said Krishna Mistry. "The mangrove stands act as a barrier against high tides from the oceans," he said, but rising sea levels and high tides are making the freshwater salty. He said subsistence farmers are losing rice paddies and freshwater drinking supplies to the rising sal****er tides and that many try to survive by poaching and by overfishing in the 104 islands in the region. "We are surrounded by water, but don't have a single drop to drink," Krishna Mistry said. "The changes in monsoon patterns are leading to more unpredictable weather. Many people are living on the edge, with no other place to go." Norbu Sherpa, an expedition guide in the Himalayas, also warned of a changing landscape in the Everest region. "In the years that I have worked as a trekking expedition guide, I have seen snow lines and glaciers go back higher and higher, he said. "Meanwhile, new lakes are forming, others are growing larger and larger." Copyright 2004 The Associated Press.

Christy has spoken at coal confabs for years now. See Gelbspan's books. Of course Christy is not going to testify that the vertical distribution problems were solved this year by Fu, et al. That would displease the coal lobby. |

Your view implies that as life on earth increases its activity, it's more likely to cause the climate changes to occur faster and to one or the other extreme. I don't see it that way, climate changes will occur faster, but to oscillate around the middle not to an extreme. Life and our climate coevolve, and as life grows more pervasive the system will become more adaptive and resilient since that is a universal characteristic of systems driven far from equilibrium. As they approach the edge, systems spontaneously organize and tend to enter a self sustaining cycle. So it would find the optimum faster and stay near it. This would require that life on earth operate within principles that mimic natural ones, being adaptive, open and civilized. Which means spreading free democracies and markets that have all those mysterious and unique properties of life. They find the best solutions all by themselves. The Great Mistake of the last century is to think humans can micromanage or out-design nature. Socialism, dictatorships, oligarchies and all kinds of rigid structures imposed upon the many, by the few, gave us most if not all of our horrors. To restore nature into the affairs of humanity the power structure must be reversed. Greater connectivity among people, so that the many control the few, is the path. Just such a scenario is unfolding before our eyes...internet...new democracies and technologies. As turning points go, we live in the middle of the Big One! Jonathan s s Cheers, Alastair. |

I was only illustrating examples of states of the planet where life went on, but mankind would find it impossible with populations levels as they are at present. Moreover we cannot expect to have time to adjust. Geology shows us that the climate changes abruptly. There are very few beds of rocks which show a slow transition from one regime to another. Almost by definition bed changes are abrupt. Life and our climate coevolve, and as life grows more pervasive the system will become more adaptive and resilient since that is a universal characteristic of systems driven far from equilibrium. As they approach the edge, systems spontaneously organize and tend to enter a self sustaining cycle. So it would find the optimum faster and stay near it. I do not agree that they coevolve. That is the Gaia Theory as yet unproven. As I see it the climate is driven by physical processes such as changes in greenhouse gas concentration i.e. the PETM. Life adjust to the climate, but that can take geological time rather than that of the human time span. This would require that life on earth operate within principles that mimic natural ones, being adaptive, open and civilized. Which means spreading free democracies and markets that have all those mysterious and unique properties of life. They find the best solutions all by themselves. You seem to be arguing for laissez faire economics which brought us the General Slump, and the fishing out of the Grand Banks. There is no guarantee that systems will evolve to maximise utility. The Great Mistake of the last century is to think humans can micromanage or out-design nature. Socialism, dictatorships, oligarchies and all kinds of rigid structures imposed upon the many, by the few, gave us most if not all of our horrors. Socialism gave us the polluted Lake Baikal and a dried up Aral Sea. Capitalism led to the polluted Great Lakes, and a wasteland in the Florida Everglades. To restore nature into the affairs of humanity the power structure must be reversed. Greater connectivity among people, so that the many control the few, is the path. Just such a scenario is unfolding before our eyes...internet...new democracies and technologies. As turning points go, we live in the middle of the Big One! If we do not do something about climate change, what you say will prove only too true. It is the USA not Russia which is opposing any action. Victory in the cold war for the US does mean it can stay neutral in the hot war against global warming. Cheers, Alastair. |
