a) A lot of it! Science has proven climate change is significantly affected by human activity.
b) Some of it, but other, natural, factors contribute significantly.
c) Human activity contributes, but climate change is mostly not caused by people.
d) Very little climate change is man-made, this stuff would happen with or without people.
e) Man-made climate change is an unproven theory and basically a hoax.

Your possible answers don't really make sense, in that you can't "prove" a scientific theory. Proofs are for mathematics, not science.

Leaving that aside for the moment, the general scientific consensus is, I think, that man-made global warming is responsible for about 110% of the currently observed warming. That is, if it were not for human emissions of greenhouse gasses, the Earth would have naturally cooled by about 0.1 C rather than warming by about 1 C over the last 150 years or so.

Well, it is a theory, in the same sense that gravity, evolution and quantum mechanics are theories. That is, they are well-founded explanations for observed phenomena.

You're thinking of theory in the colloquial sense. In the scientific sense, a theory is a well-founded explanation for some physical phenomenon (e.g. quantum theory, theory of gravity). Strictly speaking, there's no such thing as a proven scientific fact.

Hey...great demonstration of your mathematical skills, dude.

There is not only no such thing as a scientific proof, there is no such thing as a scientific consensus.

Gravity is not a theory. Gravitation is a theory. One is an observed force. The other is a description of the strength of that force against distance and mass. It is a mathematical formula that was changed by the application of the theory of relativity.

Quantum mechanics is not a theory. It is a branch of science, containing many theories.

Newton's theory of gravity (or, if you prefer, gravitation - that really is nit-picking) is indeed a theory. And I'm fairly sure that, unlike his laws of motion, Newton's Law of Gravity remained unchanged with the advent of Einstein's mechanics. Is F = Gm1m2/r^2 not still correct in an Einsteinian universe?

Quantum mechanics is indeed a theory, albeit a highly evidenced and many-faceted theory.

Facts are facts. There is no such thing as a "scientific fact" unless you are Climate Scientist who desperately needs to put the word "science" or "scientific" in front of anything pertaining to his religion.

Under Newton, "gravity" was a force of nature. Einstein changed the paradigm from a force of nature to one of masses emitting graviton particles that travel at the speed of light, and if things were light-years apart then their gravity should take years to take effect..

Einstein had a problem with the infinite speed of the force of gravity. According to Newton's theory, two masses that were light-years apart nonetheless began attracting each other instantaneously. Einstein had this idea that the speed of light was kind of like a limitation on how things could operate.

Newton never had a theory called the theory of gravity. He called it the Theory of Gravitation. I was never used to define why gravity occurs, it is used to describe how the force changes with distance and mass.

No. It must be corrected for the change in mass as you approach the speed of light.

Sorry, but that's simply wrong. Gravitons are a feature of the quantum field description of gravity, which was proposed far later and not by Einstein. Einstein's description of gravity in terms of his theory of general relativity is based on classical mechanics, not quantum mechanics.

Einstein wasn't the only one who had a problem with Newton's instant propagation of gravity. Others, notably Laplace and Poincaré, had also wrestled with the problem before him. However, the propagation of gravity at the speed of light follows directly from his theory of general relativity, which does indeed assume that the speed of light in a vacuum is constant within all frames of reference.

Quantum mechanics (aka quantum theory) is not a "portfolio of falsifiable models"; it is a branch of physics based on the fundamental assumption that energy is exchanged in discrete packets, or quanta.

Reasonable question but the better view, I think, is this;

If we do get the temperature rise as predicted how bad is that likely to be?

Firstly I think that we can surely now discount the top end of the predictions after the last 19 years of no significant temperature change. So that leaves a small, less that 2c increase by 2100, change. As a maximum.

What will that do?

1, Increased area of land for cultivation, especially in the north of the Canadian Praries and the Stepps.

2, Increased agricultural fertility due to CO2 in the tropics.

3, Increased rainfall especially in the dry and semi-desert areas. This is what has happened in previous warm periods at least.

4, A sea level rise, perhaps, of maybe 0.5m. Knee high.

If you think that that is bad, well, I don't. I think it's over all good.

Why the need to fear-monger? What are you trying scare people into doing?

Didn't you write a book explaining how it's already too late? How much time do you claim that planet earth has left? 60 years roughly, 80 years tops? Are you claiming that people with differing viewpoints are going to somehow cut into the time we have left?

It must really suck to be you, living in a constant state of panic without any hope for the future, desperately needing to control the expression on the internet and living to eradicate dissenting opinions. Wow. One would think that you would have better things to do with the remaining years of planet earth than to spam this particular website.

Yes, "gravitons" specifically came later, but Einstein facilitated the paradigm shift away from Newton's "invisible force" of infinite speed by describing gravity as emanating waves which adhered to the "speed of light" limitations. Gravity waves later became represented as gravity particles.

Correct, he was not.

Unless you are quibbling over the use of the word "portfolio" I think you agree that quantum mechanics is a branch of physics which has a collection of models (and there are quite a few) that all ride on common axioms, e.g. discrete quanta, Planck's constant, et. al. Please pardon my occasional use of "portfolio," e.g. "QM portfolio." I just like that word.

I agree. Too much of this is ignored in favor of the various catastrophic scenarios. The bigger question is will the good outweigh the bad. From what I have seen, I would say yes.

Einstein did not create the concept of a graviton, but the concept was created in 1930. That is not long after Einstein. You are quite right. The Theory of Relativity was based on classical mechanics, Maxwell's equations, Lorentz's work, and the failure of the Michelson-Morley experiment.

Irrelevant. We are discussing why Newton's law of gravitation had to be modified by Einstein's work.

By that definition, there must be a Theory of Classical Mechanics, a Theory of Astronomy, and a Theory of Biology. I began to see how you can come up with a belief in a Theory of Climate Change.
