Oh, I forgot to add, here is a rebuttal of your 'questions' ....

Have fun disproving that little lot.

You cannot answer the simple questions, can you, donkey? Not only are you too ignorant of the science on which you have the gall to comment, but you refer us to the lies of a failed cartoonist, who runs a lying unscientific, fraud promotion site deceptively named Skeptical Science. It denies the truth, and has no science, and is the donkey’s reference.
Cook is not only a failed cartoonist, he has failed any attempt he has made at science, starting with his peer reviewed paper asserting the support of 97% of climate scientists for the climate fraud. The paper was disproved using the contents of the paper itself.
Pursuant to a lie by the IPCC about a “hotspot” in the troposphere, he made a fool of himself preparing a failed paper on the non-existent “hot spot”:
"How John Cook unskeptically believes in a hotspot (that thermometers can’t find)"
http://joannenova.com.au/2010/06/how-john-cook-unskeptically-believes-in-a-hotspot-that-thermometers-cant-find/
Amusingly, Cook attempted to prove the hotspot, because the IPCC had said it was the “signature” for human caused global warming. After his well publicized failure, he said:” finding the hot spot doesn't prove that humans are causing global warming. “

Besides being a failure, he seems to be mentally lacking, but he is the donkey’s scientific reference. The donkey cannot answer simple questions on science, and neither can Cook.
You have proved without doubt that you have no understanding of science, and only seek advice from liars and incompetents.
There is no science to show a measurable human effect on climate.
I have posted science, which you ignore. You can refer to no science because there is none to support your lies.

Just a reminder of the science which the donkey ignores:
“Given that carbon dioxide is indeed a greenhouse gas (albeit a mild and diminishingly effective one at currently increasing levels of atmospheric concentration), and that some human-caused emissions accrue in the atmosphere, the question of dangerous warming was a good one to raise back in the late 1980s. Since then, with the formation of the IPCC, and a parallel huge expansion of research and consultancy money into climate studies, energy studies and climate policy, an intensive effort has been made to identify and measure the human signature in the global temperature record at a cost that probably exceeds $100 billion. And, as Kevin Rudd might put it, “You know what? No such signature has been able to be isolated and measured.”
That, of course, doesn’t mean that humans have no effect on global temperature, because we know that carbon dioxide is a mild greenhouse gas, and we can also measure the local temperature effects of human activity, which are both warming (from the urban heat island effect) and cooling (due to other land-use change, including irrigation). Sum these effects all over the world and obviously there must be a global signal; that we can’t identify and measure it indicates that the signal is so small that it is lost in the noise of natural climate variation."

Not surprising when you consider that CO2 from human sources is 3% against natures 97%.
This is what the donkey ignores, and refers us to incompetent liars likeCook at Skeptical Science.

Still defending your sacked geologist Leo? It's hilarious how you persist in defending this man, long after everything he has ever said about climate, a subject he has no credibility in, has been proven wrong. He was fired for trying to brainwash students with bad science, lies and unproven suppositions, it was the students at JCU who first objected to him.

And you laughingly push his book .....

"This book is a curious read, full of misinformation, straw-man arguments, and poorly-documented assertions"

It seems unfair to criticise the dearly departed, as he can't defend himself, but then again, he failed to defend himself in life either, so WTF.

You assert that some students were corrupted into supporting the disgraceful behaviour of James Cook University towards Dr.Robert Carter, a leading climate scientist who refused to be corrupted. Did you make that up yourself, donkey?
“Dr. Carter was one of the world’s leading authorities on the science of climate change. He was the author of two books on the subject, Climate: The Counter Consensus (2010) and Taxing Air: Facts and Fallacies about Climate Change (2013) and coauthor of several more, including three volumes in the Climate Change Reconsidered series produced by the Nongovernmental International Panel on Climate Change (NIPCC) and published by The Heartland Institute. Shortly before his death he coauthored Why Scientists Disagree About Global Warming (2015).
Dr. Carter’s public commentaries drew on his knowledge of the scientific literature and a personal publication list of more than 100 papers in international science journals. His research on climate change, sea-level change and stratigraphy was based on field studies of Cenozoic sediments (last 65 million years) from the Southwest Pacific region, especially the Great Barrier Reef and New Zealand.
Dr. Carter acted as an expert witness on climate change before the U.S. Senate Committee of Environment & Public Works, the Australian and New Zealand parliamentary Select Committees into emissions trading, and in a meeting in parliament house, Stockholm, Sweden. He was also a primary science witness in the Hayes Windfarm Environment Court case in New Zealand, and in the U.K. High Court case of Dimmock v. H.M.’s Secretary of State for Education, the 2007 judgment which identified nine major scientific errors in Mr. Al Gore’s film An Inconvenient Truth.

What can you say about the liars and failures from which you source your unscientific disingenuous nonsense, donkey?
Your lies about Carter are baseless and pathetic. Your support of the climate fraud is baseless and scurrilous. You have no science to show any human caused measurable effect on climate. I have posted the science on this. You have no science, have you, donkey?

Carter was NOT a climate scientist, he had NO qualifications to call himself a climate scientist, any more than you do. I know students from JCU Townsville as I was often there during my time at JCU in Cairns, and I can assure you geology students, or Earth science students as they are now known, often complained about his off topic ramblings, finally leading to his being released.

To be fair to the man, when he stuck to his field of expertise he was very well respected, but he used his position to push his nonsense into a sphere he was not qualified to comment on, and which has ALL been comprehensively debunked.
