Scientists?
Dammit guys, don't make me be the resident hippie just because I'm a right-leaning moderate, which makes me the farthest left here.
Nobody's making you do anything.
The point here is that global warming is not caused by man. This is why we see it as “Glow-Bull” warming. Nobody really refutes the idea that the earth is warming slightly, but logic and reason suggests that natural occurrences would be a better explanation for this phenomenon. Are we not still recovering from the last ice age? Has the planet not undergone several warming and cooling trends prior to the existence of man and their EVIL Industrial Age?
Where did your chart come from? NASA revised their warming estimates a while back which showed the trend to fall off resulting in a correction to the “hottest year on record.” Algore, Newsweek and every other Liberal media rag and outlet claimed that it was 1998. After the NASA correction, 1934 became the “hottest year on record.” Your chart doesn’t show this, which leads me to believe that you have false, pre-correction information. By the way, the global alarmists had also claimed that 5 of the 10 hottest years occurred in the last 10 years, but the NASA correction revised that number down to 3.
Finally, look at your own chart. If the rate of rise in global temperatures increased around the time of the Industrial Age, you and Algore might have a point by blaming man for the relatively insignificant rise in global temperatures, but there is no acceleration or even a notable increase in temperature rise as a reasonable person would expect. I mean seriously, if more people are driving cars every year, and more cars are being produced every year, and more energy is being generated every year, and more stuff is being created every year, and so on, wouldn’t a logical reflection of this increased activity be evident in an accelerated slope or gentle parabolic curve upward?
