question is there is evidence why you dont simply accept it ?
Because there is a great deal of evidence to say it isn't so.
I never simply accept anything until it is proven. I am naturally inquisitive and naturally sceptical.I suggest you believe things you read because they fit in with what you WANT to believe. I doubt if even the most credible evidence will make you change your mind. 'Cognitive dissonance', it's called.
The man-made global warming theory is currently as credible as the Mayan calendar. Mind you, lots of unquestioning dopes fell for that one, didn't they?

Cem, you keep repeating the point of the "evidence". My previous post highlighted what is wrong about this so called evidence. It is flawed.
1. That last 50,000 years of the graph is compressed to exaggerate NASA's argument. It goes from 50,000 years ago to 1950 in one quick compressed leap. The graph showing C02 parts per million if read correctly shows it leap to a high about 1,000 year ago before man could have had any affect.
2. The "evidence" produced by NASA themselves in this graph shows three distinct peaks of C02 near on 300 ppm every 100,000 years, with the latest fourth peak about 100 thousand years after the last one.
3. The last peak is in 1950 - why is nothing shown for a more recent date? That is not empirical, comprehensive evidence.
4. Nick's link to
Business Insider has the revealing paragraph:
"49 former NASA scientists and astronauts sent a letter to NASA Administrator Charles Bolden last week admonishing
the agency for its role in advocating a high degree of certainty that man-made CO2 is a major cause of climate change while neglecting empirical evidence that calls the theory into question."5. So why should we believe a graph that produces more questions than answers, when NASA's own stance on how to read the graph and the understanding of it, when so many from the NASA fold appear to be questioning how that organisation is "neglecting empirical evidence that calls the theory [of C02 and it's true effects] into question"?
6. If I produced work at Canterbury Christ Church university that ignored empirical evidence I would receive a definite "fail" mark. So why grant so much creditability to NASA for their work?
7. I, and I am sure Nick, is not backing the capitalist system. I for one am a strong critic of that system when necessary. No as Nick states it is about science and the correct evaluation of ALL available evidence. So far NASA, and all others, have failed to convince me of their argument about C02, and especially when it seems to contradict their beliefs! Put simply man was not able to affect the C02 levels when previous peaks were recorded at 100,000 year intervals, and even the latest peak is doubtful if the true timing of it STARTING is taken into account, but due to a dodgy graph segment the casual observer could miss what I believe is a manipulation by a party who want to prove their argument at any cost.
8. Give me a graph, properly laid out, with a reading for the year 2000 approx., and an explanation as to how previous peaks of C02 occurred and then I may start to listen to NASA's argument.
