Global Warming is Happening!

Satellite measurements of infrared radiation pertaining to sea surface temperature have only been collected since 1967... And BTW, sea surface temperature is not an indicator of man-made warming because of the periodic churning of colder or warmer water to the surface in cycles. Even Global Warming advocates will tell you that... That's one of the causes they credit for the actual cooling that has been happening for over a decade... "Well, we would be measuring warming if the cold water hadn't been churning to the surface".Since 1978 Microwave sounding units (MSUs) on National Oceanic and Atmospheric Administration polar orbiting satellites have measured the intensity of upwelling microwave radiation from atmospheric oxygen, which is proportional to the temperature of broad vertical layers of the atmosphere.Satellites do not measure temperature. They measure radiances in various wavelength bands, which must then be mathematically inverted to obtain indirect inferences of temperature. The resulting temperature profiles depend on details of the methods that are used to obtain temperatures from radiances. As a result, different groups that have analyzed the satellite data have produced differing temperature datasets... The satellite series is not fully homogeneous - it is constructed from a series of satellites with similar but not identical instrumentation. The sensors deteriorate over time, and corrections are necessary for orbital drift and decay. Particularly large differences between reconstructed temperature series occur at the few times when there is little temporal overlap between successive satellites, making intercalibration difficult. [1]In other words, you can make the data say whatever you want depending on the scam you're running...The collection of surface temperature data is more complicated than looking at a thermometer and recording a temperature... Intellectually honest people understand this.The claims for or against "Global Warming" (or is it "Climate Change"???) each require very complex man-made models of interpretation and forecasting based on data collected from widely disparate sources and simulations of data to fill the gaps where information is lacking.Again, based on the VERY SELECTIVE inclusion/exclusion of data used by any given model, the data can "say" whatever you want it to "say".Read for yourself regarding instrument decay, etc... Also, NASA and NOAA admit this when you dig deep enough.Lastly, your claims that we have been warming in the last decade are false. You pick two years (a relatively cold one from the 70's and a relatively warm one like 2012) and then extrapolate a trend. However, if you take all of the data from all of the years, averaged, you find that there is no upward trend. We are actually cooling! [2]Moreover, when you take into account urban encroachment upon land-based temperature sensors, you find that focused, local bias of these temperatures (which averaged in with the measurements from the rest of the country) throw the results way off (giving the appearance of higher global temperatures). According to NASA:"Development produces heat islands by replacing vegetation, particularly forests, with pavement and other urban infrastructure. This limits plant transpiration, an evaporative process that helps cool plant leaves and also cools air temperatures, explained Robert Wolfe of Goddard, one of the scientists who developed the method. Dark city infrastructure, such as black roofs, also makes urban areas more apt to absorb and retain heat. Heat generated by motor vehicles, factories, and homes also contributes to the development of urban heat islands." [3]"As has been well documented, global warming has gone AWOL and in some regions of the world, global cooling trends have materialized, which scientists across the world are starting to express concern with. In the key crop regions of the U.S., there has been an extended cooling trend that persists despite the immense human CO2 emissions released over the last two decades. [The four] NOAA charts (below) depict those cooling trends across the a wide swath of American agricultural production. These charts represent the main American corn, soybean, spring and winter wheat growing areas.What the huge U.S. breadbasket needs at this point is a few years of some good old fashioned global warming that will reverse the potential devastation a mass cooling would deliver to crop yields."
