Ice Ages versus Man Made Climate Change.
"In the previous graph which covers 450,000 years, we see the exact same relationship between Co2 and temperature" This statement is false. In the graph of graph of 450000 years and the graph of 1850-present the relationship between CO2 is different. What's different is that CO2 and temperature start rising simultaneously when before they didn't. It's also interesting to note that the"unimportant" perfluorotributylamine gas started to be produced in the Mid-20th century is only a decade or two off of the time when global temperatures started rising more drastically. The last peak is actually quite different. It shows that the temperature started to rise less rapidly and then it suddenly started rising at a much higher rate when you look at it closer up in the 2nd graph. "The final graph provided by Con shows a speculative difference between our current measured temperature and then the "blue line" shows what would have happened with "NO HUMAN INFLUENCE". This is pure speculation and has zero bearing on reality. Unless the creators of this graph have somehow managed to visit a parallel universe where Earth has no human inhabitants, this graph should be disregarded entirely because it is pure fiction. This is a big part of the problem with Global warming science, many of these exaggerated claims like this last graph are based on nothing but speculation." Actually this graph is not pure speculation. This graph was created from data taken from a supercomputer which modeled the climate using all available knowledge. So it should be taken quite seriously. In addition the red line so closely following the actual temperature is good evidence that it is not pure fiction or speculation and is actually likely to be quite reliable.
