It is related to the cognitive bias of illusory superiority and comes from the inability of people to recognize their lack of ability.en.wikipedia.org › wiki › Dunning–Kruger_effectWell koan thats where you logic falls apart. You keep tossing about numbers of scientists that say global warming is true, which proves nothing to be honest as all people used to think the world was flat. If so how much has the earth warmed in the past 100 years? I will answer that for you, as near as we can tell less than 1C. Over 2/3 of the earth is ocean so no temp measurements there. 100 years ago, heck even 20 years ago there are very few actual measuring points on the earth so this is very difficult to accurately determine. How much has the ocean gone up due to glacial melt? I will also answer that for you, near as we can tell 10cm in the past 100 years however those figures are highly inaccurate as sea levels were measured with logs on the shoreline until the 1990s. If you consider plate tectonics, orbit shifts etc. the figure is likely closer to 0. Now what is the minimum CO2 to sustain life on earth? Let me tell you again, 300 ppm is required for healthy plant growth. During the last ice age CO2 was as low as 120ppm. CO2 is now at a level of 420 ppm. That is an increase of 0.00012% above what healthy plants require. If as you say may scientists are absolutely positive about global warming based on the above facts, I think you lost your argument. In addition if people are now graduating from Universities basing science on such sketchy figures I also rest my case on the quality of education.
