As for lakes in Africa being too high in CO2, I don’t know. I do know that crops in water like duck weed can fix nitrogen and release oxygen while fixing some carbon and support fish in the lake, and attract ducks. Growing Cattails around the lake perimeter should also fix carbon and the tubers would be a wonderful source of 19% protein, after a fermentation distillation cycle to make local fuel for cooking or transportation. Stripping out the cattails as soon as they are grown and allowing regrowth would remove carbon from the lake.

Commercial farming of kelp can also add to oxygen production and alcohol fuel as a by product, while trapping CO2 as a result of man’s intelligent action with nature. The profit motive of people awakening to health concerns will drive more expansion of Permaculture and Organic farming. The death of the FRN will reduce the use of commercial fertilizer. More jobs in the fields, less around DC.

I also fail to understand why it is not discussed that the people who promote a tax on Carbon are almost all socialists grasping for more control over everyone’s lives, and a CO2 Tax is a very sensible vehicle for draining our lives of even more of our labor.

Arctic fluctuations are also real. NASA said that wind shifts were responsible for the massive decline of the ice sheet during the normal reduction period in the summer. The winds blew ice into warmer waters increasing melting. NASA said this has been going on for around 8 years. On the other hand the ice flow in the Antarctic reached new record highs. Or is global warming not global?

Pointing to thinning ice in some places is cherry picking if one also ignores growing ice sheets in other places. Ice is melting in some parts of Iceland and growing in other parts. Glaciers around the world are often in retreat while a short distance away another glacier is growing. One cause of glacial melt is pressure. If ice builds up the increased pressure melts off ice underneath it quicker.

The CO2 argument is relatively simplistic because Mr. Karlan looks at water vapor, clouds and CO2. His argument is simplistically naive. If water vapor and clouds are not increasing then only CO2 can be responsible by process of elimination. That argument assumes that all other factors which were excluded from the list are not worth mentioning including the impact of solar fluctuations.

It would seem that with massive and rapid climate change having occurred frequently in the past, long before man even existed, that one would need to explain why those changes took place and exclude all those reason before moving on to the assumption that C02 is responsible. This is especially true as the impact of CO2 is not linear. Doubling CO2 does not double the impact. Each increase has less effect than the previous increase.

We also know that the last major ice age (not the Little Ice Age) ended when the oceans warmed first. CO2 increases followed the warming not preceded them. While humans are releasing C02 is it possible that nature is also releasing more CO2 resulting from the end of the Little Ice Age. Could it be the warming that is responsible for much of the increase in CO2 and not just man?

We also know that for about 10 years now the global temperatures have been stable if not declining. The recent high (which is well below previous natural warming highs) was in 1998 and there has been little since. And a recent study of 600 cities and their temperature increases showed a pattern identical to what the IPCC and others are saying is happening. But when the 15 largest cities were removed from the data the trend was downward temperatures in the others. This would indicate that the adjustments in the climate models to account for the “heat island” effect on temperatures has been too low and needs adjustment.
