Today here in upstate NY we are expecting a foot of snow. What's up with that? Where is all that wonderful GW I've been hearing about? Would all you SUV owners please drive up here and rev your engines until spring returns? Come quick, I'm getting chilly.

The 25 years I spent in the Prudhoe Bay Oilfield there were 100s of scientists studying everything from tundra grass to ice crystals in the upper atmosphere. Many if not most of the studies were paid for by BP and the other oil companies. They came from Universities all over the World to further their knowledge of the Arctic and the impact of oil exploration and production.

Replying to: gagrice (Oct 28, 2008 5:53 am) It would be curious to see how many weather records have been broken this decade vs the previous one. I'm sure a computer model could compensate for the difference in the length of time. Then we could find another computer modeler to compare weather to climate. |

Replying to: oldfarmer50 (Oct 28, 2008 5:27 am)  You would think by now significant portions of NYC would be under water due to the artic melting ... I am now in shorts and short sleeve polo shirt (not in upstate NY). But then it was that way before I left for upstate NY, and by all indications 34 years later is pretty much the same. I might have to put on socks to break this global warming cloud cover that is fixing to burn off, and go to 77 degrees. |

Replying to: avalon02wh (Oct 28, 2008 4:26 am) The Earth only has a molten core because the sun keeps it relatively warm on the outside. The Earth - in the cold of space, absent the sun, would be frozen solid fairly early in its 4 billion year history. There would be no daily rotation, and no magnetic fields generated in the core. There is a relatively minor amount of radioactive materials that might provide a degree or 2 of heat. The Sun thru its gravity provides the rotational energy, and the bathing radiation and light, and warmth to keep the core molten, the ocean's unfrozen and the magnetic fields around and in the Earth. The Sun is the original source of all energy that has, is and will be used on Earth. http://www.astronomynotes.com/starsun/s3.htm "The first basic question about the Sun is how bright is it? It puts out A LOT of energy every second. How much? The answer from our measurements is 4 × 10(X26) watts. Such a large number is beyond most of our comprehension, so let's put the Sun's total energy output (ie., its luminosity) in more familiar units. It is equal to 8 × 10(X16) of the largest power plants (nuclear or hydroelectric) on the Earth. Our largest power plants now can produce around 5,000 Megawatts of power. Another way to look at this is that the sun puts out every second the same amount of energy as 2.5 × 10(X9) of those large power plants would put out every year---that's over two billion!"

Replying to: avalon02wh (Oct 28, 2008 3:54 am) One other point though: many people don't understand the difference between correlation and causality. Just because humans may have increased CO2 output and global temperatures may have risen doesn't mean there's any relationship between the two. We have a correlation. Yes CO2 is a greenhouse gas, but the percentage increase of CO2 presently in the atmosphere is tiny. Some studies suggest that elevated temperatures cause CO2 release trapped in ocean waters... I'm all for research, but determining causality with absolute certainty requires control of all other factors. I'm skeptical humans are even remotely close to having this capability for a system so large as the earth. The primary reason there are so many conflicts for what is the best "diet" is failure to be able to control for all factors. |

Replying to: avalon02wh (Oct 28, 2008 3:54 am) This generation is tired of the nonsense and "dirty stick" that our ancestors have left for us and people like you that don't want to help clean up the mess and prevent future messes. |

Replying to: mediapusher (Oct 28, 2008 8:59 pm) Thats not quite the same topic. I'm all for non polluting clean electric vehicles and a "clean" environment. I just got back from a national park and love nothing better than a pristine environment. I'm talking about Global Warming! I never said I advocate pollution. I'm just tired of all those brainwashed by the media to think that GW caused by humans is a fact. I agree totally about past generations causing future generations problems, but sadly this is nothing new. The people like me comment is putting me in a category without any merit. The fact that I'm not convinced humans are the primary cause of GW or may not even be able to influence it does not mean in any way that I advocate trashing the planet. Also humankind's impact on global temperatures is the the topic at hand. if you don't care why read the forum? |
