From a discussion on two dimensional carbon sheets called graphenes:
This thoughtful if somewhat innumerate rumination
First I would like to say that Graphene is a exciting new material. The possibilities are endless and I see that in the future that carbon products will out number all others materials. Looking forward 500 years or so it’s possible that carbon can become in short supply. Right now we are faced with an abundance of carbon in our atmosphere it is not that we have too much carbon on our planet it’s that carbon is just in the wrong places. What if a new products start to deplete the carbon resources? What if instead of global warming we are heading towards an ice ball earth? I know this is unlikely not impossible we have always been known to overdo. We should take advantage of these new technologies and keep in mind everything has a price. I see products like Graphene and other nanotechnologies saving lives and improving our way of life. It’s up to us how we proceed and keep in mind for everything we take there must be something that we give.

you have touched on a very touchy subject. The politically correct statement is not global warming, but global climate change. That way when the weather warms up we can take blame for it as well as when it cools. Okay, I’m being a little facetious here. The last interview that I heard from Professor Kaku is that he believes in man-made global warming and that interview was right after the climate gate scandal. Even though I’m a big fan of Professor Kaku, I don’t think we can say with absolute certainty that it is man caused. The evidence on both sides is mostly circumstantial that can point to either a natural or man caused phenomenon. What we do know is that Carbon Dioxide is higher on Venus where there is a runaway global warming, but is that a cause, effect, or because there are no plants on the surface to absorb it like there is on Earth. The evidence is very shaky on Carbon Dioxide’s role in global climate change. What one group that supports man caused global climate change is saying that it is caused more by the sulfuric acid in the atmosphere which used to come out of our manufacturing plants very heavily, but no longer does due to environmental regulations in the United States. Many countries in the world don’t have these regulations so sulfuric acid is still coming from their manufacturing plants. This fits with the model of Venus as well as it has several layers of Sulfuric Acid clouds caused by the much higher volcanic activity on that planet than on Earth. So now the question is, if this is the cause, does the manufacturing of Graphene and other nanotechnologies produce sulfuric acid byproduct into the air as untreated gasses from coal burning plants and other manufacturing plants do. If it doesn’t, great, I hope we can move the rest of the world to manufacturing with Graphene as quickly as possible. On the other hand, if it still does can we convince the other countries to use the same scrubbers to lessen man’s most probbable impact on global climate change. China has already firmly said no the last time I’ve heard them mention anything about using scrubbers.
I like the big think site, but its comment sections have the usual problems…
