Global Warming – Just Facts* Instruments located on satellites can measure certain properties of oxygen that vary with temperature. Antares Auto Tune 4 Hack . Data from these instruments is used to calculate the average temperatures of different layers of the Earth’s atmosphere.[4.The lowermost layer of the atmosphere, which is called the “lower troposphere,” ranges from ground level to about five miles (8 km) high.[4.According to satellite data correlated and adjusted by the National Space Science and Technology Center at the University of Alabama Huntsville, the average temperature of the lower troposphere increased by 0. F (0. 3. 3ºC) between the 1. For reference, a temperature analysis of a borehole drilled on a glacier in Greenland found that the location was about 2. F (1. 2ºC) colder during the last ice age than it is now.[5. Sources of uncertainty in satellite- derived temperatures involve variations in satellite orbits, variations in measuring instruments, and variations in the calculations used to translate raw data into temperatures.[5. A 2. 01. 1 paper in the International Journal of Remote Sensing estimates that the accuracy of satellite- derived temperatures for the lower troposphere is “approaching” ±0. ![]() ![]() Retrouvez toutes les discothèque Marseille et se retrouver dans les plus grandes soirées en discothèque à Marseille. Rugged PC Review covers all aspects of rugged computing, including reviews of rugged and semi-rugged notebooks, Tablet PCs, tablets, slates, pen computers, industrial. ![]() F (0. 0. 3ºC) per decade, or ±0. F (0. 1ºC) over 3. According to temperature measurements taken near the Earth’s surface that are correlated and adjusted by NASA’s Goddard Institute for Space Studies, the Earth’s average temperature warmed by 1. F (0. 8ºC) between the 1. According to temperature measurements taken near the Earth’s surface that are correlated and adjusted by the Climatic Research Unit of the University of East Anglia in the U. K., the Earth’s average temperature warmed by 1. F (0. 8ºC) between the 1. Fort jackson Table of Contents 6WELCOME TO FORT JACKSON. 6 7ARRIVAL.Sources of uncertainty in surface temperature data involve “very incomplete” temperature records in the earlier years,[5. A 2. 00. 6 paper in the Journal of Geophysical Research that calculates uncertainties in surface temperature data states that a. Oceans constitute about 7. Earth’s surface.[7. Changes in air temperature over the world’s oceans are typically based on measurements of water temperature at depths varying from less than 3 feet to more than 4. This data is combined with changes in air temperature over land areas to produce global averages.[7. A 2. 00. 1 paper in Geophysical Research Letters contrasted water and air temperature changes in the tropical Pacific Ocean using three sources of measurements. One of these was a series of buoys, each containing thermometers located ten feet above the water and at one foot below the water. The study found that water temperatures increased on average by 0. F (0. 1. 3ºC) per decade between 1. F (0. 0. 1 to 0. 0. C) per decade during the same period.[7. A 2. 01. 1 paper in the Journal of Geophysical Research examined the locations of 1,0. United States. The paper found that 9. F (1ºC) or more.[7. For example, some stations are located over asphalt (making them hotter at certain times), and others are located in partial shade (making them cooler at certain times). By comparing data from poorly positioned stations with other stations that are properly positioned, the study determined that the temperature irregularities in the poorly positioned stations cancel one another so that their average temperature trends are “statistically indistinguishable” from the properly positioned stations. As of July 2. 01. From 1. 97. 9–2. 01. F (0. 0. 7ºC). The largest gap between any of the datasets in any year was 0. F (0. 2. 1ºC), and the smallest gap was 0ºF/C: [8. To reconstruct global average temperatures in the era before instrumental measurements were made on a global scale, scientists use proxies that respond to changes in climate, such as the widths of tree rings and certain elements of the geological record, to estimate temperature variations in the past.[8. The Intergovernmental Panel on Climate Change (IPCC) is a scientific body established in 1. United Nations and World Meteorological Organization. It is the “leading international body for the assessment of climate change,”and its “work serves as the key basis for climate policy decisions made by governments throughout the world….”[8. The IPCC states. To determine whether 2. The first IPCC report (1. It shows a “Medieval warm period” that was warmer than the present era and a “Little Ice Age” that was cooler. The report states that. Little Ice Age rather than a direct result of human activities. So it is important to recognize that natural variations of climate are appreciable and will modulate any future changes induced by man. The second IPCC report (1. Earth’s Northern Hemisphere from 1. The third IPCC report (2. Little Ice Age’ and ‘Medieval Warm Period’ appear to have limited utility in describing … global mean temperature changes in past centuries.” The report contains the following graph of average temperature changes in Earth’s Northern Hemisphere, showing higher temperatures at present than at any time in the past 1,0. This graph is called the “hockey stick graph” because the curve looks like a hockey stick laid on its side (click on the footnote for a graphic illustration).[9. The red part of the curve represents modern instrument- measured surface temperatures, the blue represents proxy data, the black line is a smoothed average of the proxy data, and the gray represents the margin of error with 9. The IPCC’s hockey stick graph was adapted from a 1. Geophysical Research Letters authored by climatologist Michael Mann and others. This paper was based upon a 1. Nature.[9. 5][9. 6] Multiple versions of this graph appear in different sections of the IPCC report, including the “Scientific” section,[9. Synthesis,”[9. 8] and twice in the “Summary for Policymakers.”[9. This graph has been the subject of disputes in scientific journals,[1. Freedom of Information Act lawsuit.[1. Just Facts presently does not have the resources to conclusively assess all the competing claims on this issue, but the facts we have verified are as follows. The visual accord between the red instrument- measured surface temperatures and the blue proxy- derived temperatures is the result of statistical operations, not concurring data.[1.The authors used a statistical operation to generate the graph that does not yield a simple average of the proxy data but emphasizes any data with a hockey stick shape, placing up to 3.

This graph, which is called a “spaghetti graph,” is constructed with data from 1. Click here for facts about the IPCC’s practice of splicing proxy studies with instrument- measured surface temperatures.* The fifth IPCC report (2. This report contains the following spaghetti graphs of proxy studies spliced with instrument- measured surface temperatures (the black lines): [1. The following are sources of uncertainty in proxy- derived temperatures. V]ery few” proxy “series are truly independent: There is a degree of common input to virtually every one, because there are still only a small number of long, well- dated, high- resolution proxy records.”[1. A 2. 01. 1 paper in the Annals of Applied Statistics found that “the most comprehensive publicly available database” of “proxies do not predict temperature significantly better than random series generated independently of temperature.”[1. T]he raw data are generally subjected to some form of statistical manipulation, through which only part of the original climate information can be retrieved (typically less than 5. M]ost” proxies respond to “seasonally specific” temperatures, not to average annual temperatures.[1. The margins of error depicted in graphs “do not reflect all of the uncertainties inherent in large- scale surface temperature reconstructions based on proxy data.”[1. The authors of the IPCC report and the papers cited in it select which proxy data to include,[1. University of East Anglia’s Climatic Research Unit (CRU). The materials were authored by some of the world’s leading climate scientists and accompanied by the following note. We feel that climate science is too important to be kept under wraps.
