[quote]QUOTE: Originally posted by tomtrain Okay, daring to be dumb here. Some questions. This report talks about surface temperatures. What about temperatures higher up in the atmosphere? Is there no way to determine their past nature compared with today? And do they have more of an impact on overall climate? This whole existence we're part of is dynamic. We can't hold time still. In terms of eras of time, carbon moves back and forth from solid states to gaseous states. How are we to know what is "liveable"? As far as we can predict, the Earth will use up its core heat eventually, and turn into a cold rock like our neighboring planets. To aspire into the future, should we as humans focus more on developing ways of existing that are not tied to living conditions on Earth? [/quote] Good questions. I once asked a scientist why the earth is hot inside. I'll bet you can't guess what he told me. The weather changes all the time. The seasons change. It would not be improbable, and evidence suggests, that the climate changes as well. It is not clear that the change will cause significant damage, and it is certainly not clear that man's burning of fossil fuels is causing it. And yet we are barraged by this shrill crisis mongering that is blowing this up to near Biblical proportions as though it is nature's revenge for the material sins of mankind and especially the developed world.
