The man-made global warming argument is furthered by liberals attempting to extract guilt and money from nations and businesses that produce, and transfer the funds to a select few that will "know better" and will "protect". The rest of us. This is an example of corruption at it's highest level. (Any money being extracted from producers goes into the pockets of greedy politicians and so called businessmen including monies diverted to poorer countries.
It is basically organized where you pay protection money so that you can be protected from the recipients of the remuneration.
No it was not warmer 7 to 800 years ago. Did not read any further. No need to. Try again. Like jerm, you are very confused. Too much right wing propaganda and too little science. and the right side of that chart is even higher now.
I mean, the pschology of you is interesting. I wonder if at this point, your lawyer-lies have actually turned against your own sense of what is true. You have argued in defense for the murderer so much that you have now brainwashed yourself into thinking that he is actually innocent. Or perhaps you just enjoy lying. Because at this point saying there is no science is either breathtakingly ignorant and irrational or you are simply lying. It does come so easily to lawyers. You remind me of the team that got OJ off.
We are currently around 2.5 degrees cooler than 1250 to 1300 AD and roughly 4.8 degrees cooler than 3000 years ago. We basically oscillate around a mean temperature with an overall gradual declining average temperature. We have been about 4 degrees cooler than now during the past 5 to 600 years so I can see why folks looking short term like you do, believe the sky is falling. It's this short sighted vision by some that gives rise to this inaccuracy known as man made global warming. There of course is no such thing.
Your chart is false by the way. The mini ice age that occurred after 1300 was a much bigger temperature anomaly than the .8 degree suggestion that this chart indicates. Absolutely corrupt and inaccurate chart here.
