I scanned through and didn't see it mentioned anywhere, but has anyone else heard about this problem?
The entire global warming problem is contingent on the concept that an increase in CO2 leads to higher temperatures, and this is based on the data compiled into the nice chart that Al Gore displays and comments, "They look like the belong together." Or something like that.
The problem is that CO2 amounts don't precede the increase in temperature, they actually lag behind the temperature changes by about 800 years. This can be explained by the idea that as the world heats up, the oceans heat as well. As the oceans heat, they release carbon dioxide into the atmosphere. Of course this leaves the question, "Why does the planet heat up?" to be answered, and while the data is much more limited, there seems to be a very strong correlation between solar activity and global temperature.
Has anyone else come across this line of research? Or have anything that builds on or refutes this?
