The issue of global warming was revitalized for me when I made a statement that the current global temperature is 58 degrees Fahrenheit and this has only risen by half a degree in the past century. This stimulated a wonderful friend of mine to challenge me to provide the data . The two of us together discussed and investigated the data.
What I concluded is that the thermometer data which goes back at least a hundred fifty years is not very reliable because it probably covered less than 15 percent of the globe and was derived from a changing sample of thermometers.
It didn't include oceans, the poles and most of the uninhabited world of Russia, China and Africa as well as mountain ranges. Furthermore there is strong evidence of changing and backdating numbers for different stations. This was evident in the disclosures about the Hadley Center at East Anglia University and my own records of the data. (It was a Russian computer college that publicly disclosed the email evidence of the fraud.)
Fortunately, at the very same time that a rise in global temperature was occurring according to thermometer data, it was the first year the United States put a satellite in orbit to measure global temperatures.
Since that time we have gathered 34 years of satellite data from at least five different satellites. There are two extraordinary advantages of the new data.
The first is that we do not have to deal with selecting thermometer stations to be added or subtracted from the data . The satellites circle the globe roughly every 90 minutes and they cover the entire planet so that the number they come up with after each circumnavigation is a reliable number. We have data now from 12,400 days.
The second thing that we have is observations of the most rapid increase in temperature for the globe, that occurred between the beginning of 1996 and late Spring of 1998. We know that that rapid rise occurred and was accurately measured.
Now that we have the data you can manipulate it by going to our Google Documents page here, and take the data to use for your own purposes.
This is important because the conclusions you come to are your own. They probably won’t match many other people’s observations of the same data.
My personal conclusion on the basis of this 34 years of reliable data is that if you take the full 34 years we will see a roughly 1.2 degree centigrade increase in global temperature for a century if it continues exactly as it did for the 34 years. That is considerably lower than the IPCC’s lowest estimate.
However I see two different global temperature patterns in the satellite data. One period was stable from 1979 to 1996. Then there was a global disruption between 1996 and 1998 that set the new global temperature level .3 degrees centigrade higher. It has been stable again for the period 1998 to 2014. If we project the pattern from the past 16 years forward we see virtually no increase in global temperature for the rest of the century.
I need not make any strong statements about global warming. If you want to take the full 34 years of reliable satellite data you will get a 1.2 degrees centigrade warming over the next century. If you want to take the most recent (roughly) half that amount of data, you will find virtually no global warming trend.
Its up to you. You have the data.
