Climate change/global warming due to man's activities is a sad reality. End of. Depsite all the smokescreens and chess games funded by vested interests etc, and occasional examples of some shakey pro-data at times, the reality of the fact is easily discernible with oppen minded patience and research. The conclusion you reach speaks for itself. Anything else is convenient denial.
So, you disagree with the IPCC's recent report for policymakers? Cool, show us the man-made signal in climate change then, coz they can't. Despite the CO2 rises, we've had 2 years of falling sea temperatures and levels which doesn't fit with the scaremongering...but you know better than NASA. The global temps are observed lower than the IPCC's last high, medium AND low predictions which is WHY they CANNOT spearate the human signal.
Try something, just have a read at those e-mails from our climatologists as you can see exactly what they are doing by ignoring anything that doesn't fit with the religion. The problem is, you won't. Just like the IPCC will not entertain dissenting views at all. Again, as shown clearly in the e-mails. So, that'll be robust science then.
