No that is not right sprint, you are falling for the confusion trick these conmen pull.
They are professional liars, the whole denialist campaign was the brainchild of the same company that tobacco companies used to ty and stall any facts about the harm from smoking getting out.
They had doctors on the payroll telling people that smoking was actually good for you.
Then when that become untenable, due to the weight of scientific evidence, they looked to minor disagreements, on non-crucial points, to try and portray the image that even scientists disagree about it, so nobody really knows.

Sound familiar??

That scientist(his specialty is actually economics, but as it relates to climate change policies) has not voiced any opinion that climate change is not real, or that it is a scam, or anything of that ilk, as far as I can see, but he has raised relevant issues about the specific policy issues relatung to Emmission Trading Schemes, and that is good enough for the denialist PR machinr to trumpet him as a dissenting scientist who disagrees with the whole climate change issue, just to try and add further confusion, where no confusion actually exists.

All reputable scientists acept that climate change is real, and they put a statistical probability of 99% that humans activity is making it worse, that is the simple fact, and all the other bull you hear is just that, total bull to try and portray an image of scientific debate, and discord, when the science is very well understood, and agreed upon by all reliable climate scientists.

The scientists like Monckton, are very strange people, who make ridiculous claims, and utter absolutely false statements, for reasons we can only speculate on, but the simple fact is it is they who cannot be trusted, not the many thousands of reputable scientists they disagree with.

So, do not let these professional liars fool you sprint, like I said, never take their word for it, in fact go to a reputable site like realclimate.org and see the individual scientific debunking of all the denialkist lies, and then see who you really believe.
