Global warming exists

Introduction: There are many data sets one has to look into to determine whether global warming is real. There are three main ways of determining global temperatures, 1) Surface Scanners, 2) Satellites, 3) Air Balloons. Balloons and Satellites are considered the most accurate measurements, surface scanners pick up the same trends but to larger degrees. Many people blame this on the urban heat island effect, though using corrected data (i.e. only sea and rural scanners) you still get the warming trend. All three major USA sensor groups all find global warming, and I will discuss this later. My points revolve mainly around data, if not on all data, from the three main stations. They will be discussed in order of accuracy, the most accuracy in question first. ===Surface Scanner Data=== Now there are three major governmental organizations that are considered "warmest" organizations, in other words their data shows warming and they therefore adopt the global warming hypothesis. 1. NOAA data[1] We see consistent warming, like all temperature there is temporary flat lines/decreases but the overall trend is up. 2. British data Using graphs, we see similar data. Except the warming trend from 2000 on is a slight decrease, the overall trend (which is my BOP to prove) is still upward. It is almost a carbon copy.[2] 3. NASA data The NASA data is the most cited as its graphs look like the most warming has occurred (because of the 15 degree format they use). Their data states “[…]global cooling after 1940 was small, and there was net global warming of about 0.4°C between the 1880s and 1970s.”[3] Their graphs look like this: About a .4 degree increase since 1900, based on NASA. Objection: Urban heat island effect This is the most common objection for the surface scanner data, that’s why its “accuracy” is in controversy. So in order to end the controversy scientists followed these steps: Using only data gained from buoys or ships Instead of using individual data average it together to smooth over the “bumps” Smooth the data to account for the urban heat island effect Now the data gathered after these regressions where preformed got the same trend. In other words, the accuracy is not in question as the urban heat island effect failed to affect the overall trend. Here is a graph so you know I am not lying:[4] As we can see from surface scanners, global warming likely exists. ===Balloon data=== The main type of balloon data is upper air, which is what I will look into. Upper air The upper air data has lead most scientists to believe global warming is ”undoubtedly” real. The NOAA states, “Data collected and averaged between the 850–300 mb levels (approximately 5,000 to 30,000 feet above the surface) indicate that 1958–2011 global temperature trends in the middle troposphere are similar to trends in surface temperature; 0.13°C/decade (0.23°F/decade) for surface and 0.15°C/decade (0.27°F/decade) for mid-troposphere. Since 1976, mid-troposphere temperatures have increased at a rate of 0.17°C/decade (0.31°F/decade). For 2011, global mid-troposphere temperatures were 0.34°C (0.61°F) above the 1971–2000 mean—the ninth warmest on record.”[5] The graphs tell the same story: Now this cannot have any little urban heat island effect, using the black line (surface scanners) and the red line (upper air data) we see the same trend and a little more warming from the upper air. ===Satellites=== Although balloons and surface scanners are good measurements’, satellite data is still considered the most reliable data with over 80% accuracy in a 0.1-degree range. Satellites can quickly gather global data whereas the balloons target specific areas and are averaged together, and surface data is stationary.[6] The most recent data shows the whole earth is warming. Satellite data, also, shows similar patterns of surface and upper-air data. A few works often cited by skeptics claiming satellites show cooling have been debunked by scientists as most data shows the satellites get similar trends to surface data. Also note this measurement cover 80% of the world, and within a few days’ gets data from 100%.
