Anyone who says that climate isn't changing has their head in the dry dirt of the Oklahoma Dust Bowl. Recorded history shows clearly that there is climate changes over time. Indeed, climate shifts have influenced man's history more than any other single event source. Scientific evidence shows that climate changes constantly. The problem I have is the intensity which climate cultists point to humans as the cause.
Given that the magnetic poles have been shifting regularly, if slowly, means that the solar wind's interaction with the Earth will change as the magnetic field moves. ("Settled science"? I haven't heard any nay-sayers.) How about the argument that carbon dioxide has been "building up"? Yet one study I finally found, that looks at wider time periods than a century (http://www.biocab.org/carbon_dioxide_geological_timescale.html) suggests that (1) temperature has no significant correlation with CO-2 content, and that we are coming out of a period of low CO-2 concentrations.
Does this mean that man is completely blameless? No. Temperature is a function of released energy, and the Earth had stored sunlight for millions of years. We are releasing that stored sunlight at an increasing pace, which eventually ends up in the atmosphere, one way or another, as heat. How much is due to technology, and how much is a by-product of man's actions such as the clear-cutting of Amazon rain forests and covering the land masses with asphalt and concrete, and how much is caused by other, non-man-made changes? So the question is whether the existing natural system for expelling heat are up to the task. More importantly, details are important. How much heat does technology dump into the atmosphere? Clear-cutting (and clear-burning) of land? Other sources? Without numbers, everything is just opinion. And when it comes to such "science", one option is equally as good as another, absent accurate and provable forecasts -- I believe that is why the climage deniers hold to their beliefs. Cultists haven't proven their case, or even shown their case has merit.
Are there other solutions than those proposed by the client cultists? One way to keep heat out of the atmosphere, if that is the goal, is to keep sunlight reaching ground level from being converted to heat in the atmosphere. Photovoltaics can help, although the energy would be released -- just perhaps in a different spot or a different time; the benefit would that such energy would displace energy released from fossil fuels -- current sunlight instead of ancient sunlight. Ditto solar thermal power plants -- using today's energy instead of million-year-old energy.
Sunlight that never reaches the ground can't contribute much to the heat load. How about reflection and dispersion? Some of the energy would be converted to heat by the air itself, but the rest would escape into space in the form of radiation (light, infrared). Another way to trap sunlight so it doesn't contribute heat is to increase the surface area of leaves, to increase photosynthesis -- and that has the benefit of eating up CO-2 as well as keeping heat out of the air. (Cultists: when did you re-roof your homes with grass? It would lower your air-conditioning bills, too, by keeping the heat out of your attic.)
But is that all there is? There is considerable heat trapped in the core of our planet. Further, there are energy sources in the ground that contribute to the atmospheric heat load...but I never see that heat source mentioned in the Climate Cultist literature. What is the effect of volcanos on the solar balance sheet? We know that ash can bring down airplanes, but what is the effect of that ash in the air? It could well be that geothermal power generation, replacing fossil-fuel generation, would be an excellent way to keep the atmosphere in thermal balance. Don't hear much about geothermal from climage cultists, do you...
I was part of the generation that "grew up with the Bomb" -- and I remember all those discussions about "nuclear winter" that would be brought on by The Ultimate War. Block enough sunlight, and you drop world temperature. But you won't like the side effects.
And so I come to the end of my thoughts on the subject. If you have faith that we "need to do something" about the problem, show us your work, your accurate predictions of change, your proofs. Instead of trying to make us "believers" by trying to evangelize your faith, show something that can be vetted by the scientific method.
