As others have noted, 1850 was around the time of something called the "Industrial Revolution", when the steam engine had just been invented, and so people started burning coal to do many different things to a much greater extent than before. Of course, energy consumption then wasn't what it is now, so the effect was weaker. While back then, people did have thermometers and record the weather, things like tree rings and isotope ratios have been used in modern studies of past climate as well, and this helps to avoid errors due to any limitations on older means of measurement. John Savard Not many trees in the oceans--70% of the Earth's surface. And tree rings can't give you 1 degree C precision anyway. Deserts and icecaps are short on trees as well. Ever heard the term "procrustean bed" ? You Greens give it new meaning. Got a way for you to make an easy $500,000: http://www.junkscience.com/ |

Ah, here we a http://en.wikipedia.org/wiki/Temperature_record discusses the matter quite well. Apparently they don't need to use stuff like tree rings except for times before 1850, so I wasn't quite right. John Savard one small quote from your cite which you apparently didn't read: "The uncertainty in annual measurements of the global average temperature (95% range) is estimated to be ~0.05°C since 1950 and as much as ~0.15°C in the earliest portions of the instrumental record. The error in recent years is dominated by the incomplete coverage of existing temperature records. Early records also have a substantial uncertainty driven by systematic concerns over the accuracy of sea surface temperature measurements.[23][24] Station densities are highest in the northern hemisphere, providing more confidence in climate trends in this region. Station densities are far lower in other regions such as the tropics, northern Asia and the former Soviet Union. This results in less confidence in the robustness of climate trends in these areas. If a region with few stations includes a poor quality station, the impact on global temperature would be greater than in a grid with many weather stations.[25]" So many global warming assumptions are forced as to make predictions useless--it is a religion, not science. And, again, I know you true believers don't like this focus but "global warming" and "global warming is caused primarily by man-made CO2" are two very different concepts--even you can't be that stupid. We may well be in a natural cyclical warming cycle--it is the ultimate arrogance to assume we can turn it off if we just spend enough money. I agree we should go nuclear as our primary source of electricity-- just as Europe does-- but Greens don't like that option even given the fact that the number of nuclear power plant fatalities in the US is........zero. Wind doesn't blow evenly anywhere; solar doesn't work well at night; ac doesn't store too well in a battery, etc, etc But go ahead and make Boone Pickens richer as he plays off your fears. The government can pay for it right? No cost to the taxpayer, right? Bet you don't pay taxes but "Rolando" is not going to like Obama's socialism very much. |

You're right, they did not use electricity to light their homes, but they did light their homes with kerosine. Rolando |

Ah, so the Chinese are indeed coming after you; contrary to your argument of a year ago, it seems electricity costs are not a significant factor in your--or the Chinese--glass costs. I know, consistency is the hobgoblin of small minds, right? Or perhaps you can't remember your past posts--check the archives. The Chinese coming after me? hahahaha. How funny. They're actually buying products from us. How about that, eh? Betcha I know what i'm doing in this market better than you. Doesn't that just frost your shorts! The Chinese are coming after the wounded, not those who have a good business going. They came after Celestron, who was just about on their last legs and got rescued by Synta. Celestron, who got into several cat fights with Meade. A real shame because the only winners were the lawyers, and look where Meade is today. Stock which was at $50 not too many years ago is now worth two dimes and a few pennies. Does that indicate good management? Wonder which Chinese company will buy them out at that price? A real shame if you ask me. On the other hand, the RC makers are doing terriffic, even in this lousy market. Unca Rollo |

You continually display your ignorance of warming and cooling cycles that took place long before they could have been driven by human activities. Human were around for the last major ice age that covered most of what is now Europe with ice. Did they warm up the planet with their campfires? Or just, possibly, are natural cycles at work? |

Since the launch of the Hipparcos satellite, the trigonometric parallax of Sirius can be measured with an accuracy of a fraction of a percent. Perhaps you know that the trigonometric parallax yields the distance directly, and is not sensitive to interstellar extinction. The "mutual closing rate" (i.e. the radial velocity) is measured through shifts in the wavelength of spectral lines, and that method too is insensitive to interstellar extinction.

You asked if people drove cars in the 1800's, and I said no, they burned coal. That does not make me an expert on global climate change. Nowadays we burn oil. Both put CO2 into the atmosphere. I don't think anyone will argue that it doesn't. Unca Rollo |

You continually display your ignorance of warming and cooling cycles that took place long before they could have been driven by human activities. I haven't seen a single person disagree that there are natural climate cycles. Yet you bring the straw man up time and again. BTW, it isn't established that a sunspot minimum "produced" the Little Ice Age. It is widely believed, however, that a very small decrease in solar output acted as a trigger to a positive feedback mechanism that caused far more cooling than the loss of solar energy alone can explain. This provides a strong warning: small changes can knock us from one metastable state to another. A couple of degrees global temperature rise may quickly cascade to much more. Every indication is that the Earth's climate is not terribly stable. _________________________________________________ Chris L Peterson Cloudbait Observatory http://www.cloudbait.com |
