These globally averaged temperature data come from NASA:
http://www.giss.nasa.gov/data/update/gistemp/GLB.Ts.txt They represent the results of tens of millions of readings taken at thousands of stations covering all the lands of the Earth over the last 125 years. Yes, the data are corrected for the urban heat island effect. Unlike other weather and climate data currently coming from the United States, no government censors added 'spin' to this report. The Mean January temperature over the last 126 years is 13.997 C. The Variance is 0.13566. The Standard Deviation, or SIGMA, is 0.3683. Rxy 0.654638 Rxy^2 0.428551 TEMP = 13.575548 + (0.006629 * (YEAR-1879)) Degrees of Freedom = 124 F = 92.992086 Confidence of nonzero correlation = approximately 0.9999999999999999 (16 nines) The month of January in the year 2005, is linearly projected to be 14.411, yet it was 14.85. -- 1.2 SIGMA above the linear projection! The sum of the residuals is 25.788452 Exponential least squares fit: TEMP = 13.575858 * e^(.0004751 * (YEAR-1879)) The sum of the residuals is 25.716902 (Those who have followed this item both closely and with an open mind will note that an important trend continues here. The rest needn't waste bandwidth with their trolling) Rank of the months of January Year Temp C Anomaly Z score 2005 14.85 0.853 2.32 -- 2002 14.81 0.813 2.21 2003 14.80 0.803 2.18 1882 14.79 0.793 2.15 1998 14.64 0.643 1.75 1988 14.61 0.613 1.67 2004 14.58 0.583 1.58 1981 14.57 0.573 1.56 2001 14.57 0.573 1.56 1999 14.55 0.553 1.50 1932 14.52 0.523 1.42 1990 14.46 0.463 1.26 1992 14.45 0.453 1.23 MEAN 13.997 0.000 0.00 1900 13.54 -0.457 -1.24 1917 13.52 -0.477 -1.29 1892 13.49 -0.507 -1.38 1895 13.48 -0.517 -1.40 1911 13.48 -0.517 -1.40 1881 13.47 -0.527 -1.43 1918 13.47 -0.527 -1.43 1887 13.46 -0.537 -1.46 1904 13.45 -0.547 -1.48 1885 13.43 -0.567 -1.54 1894 13.38 -0.617 -1.67 1909 13.30 -0.697 -1.89 1891 13.22 -0.777 -2.11 1893 12.47 -1.527 -4.14 The most recent 146 continuous months, or 12 years and 2 months, on this GLB.Ts.txt data set are all above the 1951-1980 data set norm of 14 C. There are 1501 months of data on this data set: -- 716 of them are at or above the norm. -- 785 of them are below the norm. This run of 146 months above the norm is the result of a warming world. It is too large to occur by chance at any reasonable level of confidence. A major volcano eruption, thermonuclear war, or meteor impact could stop this warming trend for a couple of years, otherwise expect it to continue. |

So, you provide not one item of data or even a
single reference. Yet more fossil fool bluster and blessed ignorance. I'll stick with mainstream science and 0.9999999999999999 (16 nines) confidences of nonzero correlations, which are, approximately, facts. That is a vastly superior world view. |

You're the fool, especially if you think the industrialized world is going to shut down on the basis of what are probably minor fluctuation that may or may not be be partly influenced by manmade emissions. If you think climatological theories of any kind have "0.9999999999999999 " levels of confidence - YOU ARE AN INCOMPETENT. Now, go learn about paleoclimate as derived from CO2 from ice cores and O2 from seafloor seds. We're in an interglacial warming period. It's better to be warming than dropping out of it into an ice age. |

Shuffling between paleotemperature and paleoclimate is invalid. Ice cores are good, but too much conclusion from too little evidence can be a beartrap. Imagine someone investigating summer earth samples from the Great Plains. Would he guess that Europe was going through massive floods at the same time. Same with the deal about inter-glacial warming period. That's a suggestion from the climate record ... but we may have just completed our exit from glaciation periods, right? |

However, paleotemperature data show things don't stay the same for very long, and it's better if things are getting warmer than if they were getting colder. The observation from the data is accurate. The data makes itself makes no conclusion so it's nonconlusive not inconclusive. To jump from there to a reliance on paleotemperature data is fiction. There is no such thing as paleotemperature data - there are indirect interpretations that relate to climate and change. The same paleo data and strata has, over the years, been borrowed for a variety, and sometimes contradictory, conlcusions:- extinctions, ice-ages, extra-terrestrial impacts, and atmospheric poison catastrophes. It's interesting and useful to see if interpreted paleo data can offer additional possibilities, but it is dangerous science to say fragmented pieces of the earth's jigsaw puzzle represent detailed weather measurement or conclusive evidence of global environmental conditions. |

Yes, the data are corrected for the urban heat island effect. Unlike other weather and climate data currently coming from the United States, no government censors added 'spin' to this report. Satellites to measure temperature evenly across the Earth's surface have been operational since 1979. Data prior to 1979 relies on surface weather stations and weather balloons, which are not evenly spread around the world. Good records exist for North America and Europe over a period of about 100 years, but there have never been many stations for the 70 per cent of the Earth covered by water, or the 38 per cent of the rest that is desert or mountains. This means that scientists cannot say for sure what the average temperature of the Earth was in 1900 - and the problem gets worse the further back we go. If the starting point data for a model is wrong, even slightly wrong, it could have a major impact on the outcome. Worse, it is impossible to test the model. If you want to see how good a model is, perhaps the best way to test it is to start it from as long ago as possible, and see if the results match what really happened. This doesn't work if we don't know what really happened more than two or three decades back. As Tim Ball, Kenneth Green and Steven Scroeder, three North American climate researchers, note: 'Surface temperature records for the world are inadequate to determine the average annual temperature of the earth. The uncertainty in the global "normal" surface temperature - estimated to be 13.9 degrees Celsius...a decrease from an earlier estimate of 15 degrees Celsius... is almost twice as large as the estimated global warming in the last 100 years.' (3) Perhaps these models provide us with insights into what we don't know, but they can't predict the future of our climate - at least, not yet. When we have more powerful computers, greater understanding of the physical processes involved and a longer history of good data, it's likely that models will provide better predictions. http://www.spiked-online.com/Printable/0000000CA8CF.htm The UHI effect is cobbled together with a half assed formula based on population. Not an accurate picture. |
