Stages of Denial: ‘Geological history does not support CO2′s importance’–Just not true

Objection: Over the last 600 million years, there hasn’t been much correlation between temperatures and CO2 levels. Clearly CO2 is not a climate driver.

Answer: While there are poorly understood ancient climates and controversial climate changes in earth’s long geological history, there are no clear contradictions to greenhouse theory to be found.

What we do have is an unfortunate lack of comprehensive and well-resolved data. There is always the chance that new data will turn up shortcomings in the models and unforeseen new aspects to climate theory. Scientists in the field are working hard to uncover such things — every scientist relishes the thought of uncovering new data that overturns current understanding. But it makes no sense to reject CO2 as a primary driver of climate change today because it looks, through the foggy glasses of time, like CO2 has not always completely controlled climate changes in the past.

The climate system is complicated — even the configuration of the continents has a big effect — so one can not expect complete correlation on all timescales between temperatures and any single factor.

    True, but for the same reasons there is no sense to demonize CO2, call it a threat to the future of all life on the planet, create a world government to manage all societies through the control of carbon, build enormous uneconomical wind and solar farms, scare the b’jeesus out of children with stories of CO2 caused climate apocolypse, etc. etc..

    I’ve never heard anyone demonize CO2, as a matter of fact, plants and animals have a symbiotic relationship between Co2 and O2 (Oxygen). We breathe it every day. I’ve also never heard anyone call it a threat to all life on the planet, since most life does very well surviving an ice age (except for humans). Co2 is just one thing that can become a pollutant if it get’s out of control, as it is right now.

    Nor do I imagine that the general public has any way to create a world government that will thwart the existing fossil fuel driven political systems, at least until the blood money in politicians pockets dries up when those fuels run out.

    And, sorry, wind and solar farms are not uneconomical. We have millions of acres of unused land in the southwest alone that could produce enough solar energy to power the country a hundred times over if connected to the grid. Experimental farms in the U.K., and elsewhere are doing very well as photo voltaic cells continue to get cheaper. The cost of making both silicon-based and thin-film panels have dropped rapidly in recent years. Thin film panels can be made for about $1 per watt while various silicon models are manufactured for between $1.10 and $1.80. And that’s just for home array’s at around 5kW. If you build larger systems for big kW production, prices decrease even more. Soon it will be affordable for people to build array’s into new homes, and reduce the cost of energy by %80 of what it is now. I have builder friends that are building 2.5 thousand feet two level homes that use only around $80 in energy monthly because of new technology in insulation, hot water heaters on demand, etc. What people don’t seem to understand is that it’s not just stopping coal production, etc., but a NEW ENERGY POLICY that is inclusive of all these technologies that will make a big difference in how energy is produced in this country. What we are demonizing here is the kind of thinking that ignores these issues in lieu of making a buck on current technology at the cost of others health and welfare.

    And lastly, my kids are more scared of heavy metals, sulphur dioxide, cyanide, and all the other poisons that fossil fuels and the use of them pump into the atmosphere, and our clean water. That indeed scares the B’Jeezus out of them, me, and ought to scare you as well.
