  49.  @jojoboko6990 , your questions are vague and hardly scratch the surface of the issue. Does man play a role a climate change? Yes. But how much we don't know. You can't make a hard conclusion on that. A bigger issue is if current climate change is even a threat. I bring up photosynthesis because very little is known about that. Greg Engel talked at my university (I had lunch with him) and in the presentation he showed a picture of photosynthesis from a 7th grade textbook. It is a basic concept but when you get to the quantum level so little is known about it. I have a friend who does theoretical work on it and he tells me that the process should be as low as 30% efficient and no more than 50% efficient. But in nature it is 90% efficient. We don't know why. People like Engel and Flemming have done work with non-linear, ultra fast visible spectroscopy to gather experimental information to determine why, but that is limited as biological materials are difficult to study. My line of work studies biological materials at different temperatures and pH levels to study the folding and dynamics of them. So far we have gone to a 4 residue peptide and others have gone as large as 6 to 8. Peptides are much larger but there are difficulties doing experimental work on them. We are progressing but we are not there yet. My point in all of this is that we have very limited knowledge in biological systems. We can't make a hard conclusion that the current climate change will be bad or is a major threat as we don't know how the ecosystem will evolve or react. This is why I say the science is not settled and there is so much we don't know. You are hardly scratching the surface of the issue. When you dig deeper you end up with less answers and more questions.
