Global climate change should not be a major factor in US energy policy

Thanks to Con for accepting this debate. The resolution covers many issues, and that will make it difficult to discuss comprehensively. The virtue is that it exposes how many assumptions are stacked to get to the present policies of heavily subsidizing uneconomic green energy and discouraging the exploitation of fossil fuels. 1. Increasing warmth and CO2 are most likely beneficial The average temperature of the earth has risen about 1 degree C in the past hundred years. [1] The earth was much warmer than the present during the Medieval Warm Period (MWP) about a thousand years ago. [2] That's when Greenland was actually green and grapes grew in Scotland. The MWP was a prosperous time in human history because the growing season was longer in the temperate zone. Temperatures were warmer still during the Holocene Maximum, 5,000 to 8,000 years ago. That is when the great civilizations of the world began in China, India, and the Middle East. It was another very prosperous time. Going back in geological time, earth is currently none of the lowest points of both temperature and atmospheric CO2 concentrations. [3] The current average global temperature is about 14.5 C (58 F). [4] For most of the period of the evolution of life forms, average global temperature was around 22 C. Life flourished. CO2 levels are now around 380 ppm, less than a tenth of early levels. [3] The main depletion of CO2 is from the microscopic skeletons of plankton capturing the CO2 in carbonates which end up in limestone at the bottoms of the oceans. Because plants evolved in conditions of high CO2, they are now relatively starved. Commercial greenhouse operators artificially raise CO2 to about double current atmospheric levels, There are a few exceptions, but nearly all plant species grow faster at higher CO2 levels. This fact is supported a vast number of peer reviewed studies. More plant growth means more food, and that's good. Humans adapt much more readily to warmer climates than cold. [6] That's apparent from the distribution of human populations. The same is true of animal species. Of course, there are extremes that cannot be tolerated, but the climate change controversy is mostly about CO2 causing changes of 1 - 4 degrees C. Warmer is better. The largest disadvantage of warmth is the rise in sea level. The latest IPCC report predicts and expected rise of nine inches in the next hundred years. 2. Climate predictions are unreliable The global warming panic peaked around 2000, when confident predictions were made that the world would fry by the year 2010. In the decade since then, the world has actually cooled. [1] Why were the predictions so confident back then. The logic was as follows: (a) the earth warmed substantially from 1980 to 2000, (b) CO2 increased during that period, (c) all other factors affecting climate had been accounted for -- it wasn't the sun, volcanoes, changes in the earth orbit or anything else, (d) therefore CO2 caused the warming. The physics of CO2 alone did not explain the warming, so a multiplying effect was hypothesized and the multiplier was found to be high. About two-dozen computer models using various models built on the same principles were used to predict the decade of 2001-2010. What actually occurred was below the error band of all the model predictions. [7] One factor that was omitted was the Pacific Decadal Oscillation, a roughly-60 year cycle that peaked in the 1880s, 1930s, and 2000s, producing widespread melting of Arctic Ice at each peak. Taking the PDO into account, many now predict we are in for two or three decades of cooling. [7. 8] Last month, I attended a pitch for M.I.T.'s new effort to rebuild climate science into something reliable. [9] The prof started by saying, "I just returned from a week-long conference at Princeton. We all agreed on two things: the troposphere is warming, and we don't know why." For example, a critical element in climate models is the rate of energy transfer between the ocean surface and the atmosphere. Recent work suggests the previous assumptions are off by a factor of ten or twenty. There are many other known deficiencies. Because climate models have been proven wrong, and wrong in the direction of wildly exaggerating CO2 effects, they should not be used a basis for public policy. We should continue research until the models prove reliable. 3. Fossil fuel restrictions in the US will have little effect Let's suppose for a moment that CO2 alarmists are correct in worrying about CO2 increases. China has 23% of the CO2 emissions, the us 18%. However, the Chinese are increasing consumption at 11% per year, while the US is about stable. World consumption is growing at 5.6%, with most of the growth in developing countries. Per capita consumption in China is a quarter that of the US. India is about 1/30. There is no possibility that China, India, and the developing world are going to stay in poverty over fear of global warming. Let's suppose the US cut it's CO2 emissions in half. Because the US population centers cover a large area, transportation needs are much greater than countries where the population is concentrated, so its a lot harder to cut energy use. If the US cut by half, India and China can be expected to grow rapidly. Their populations are now about eight times that of the US, their populations are growing faster, and they want to to advance their standard of living to US levels. The US's 18% of emissions will probably be less than 6% of the world total in 50 years. If we took drastic cuts, it might be 3%. Temperature is proportional to the logarithm of CO2 concentration. If the temperature rise were 1 degree, our policy of draconian cuts would be reduce the rise by 0.026 degree, That's negligible. There is no point in it. 4. Attempts to significantly cut CO2 would cost trillions of dollars Any measure that reduces CO2 and also cuts costs will be adopted by free markets independent of government policy. For example, fluorescent light bulbs and hybrid cars save money, so people are adopting them without a government policy forcing it. Forcing it costs an enormous amount of money. For example, there are 250 million passenger cars in the US. Replacing them with $25K hybrid vehicles would cost That's $6,5 trillion. Going to $40K electric cars would be $10 trillion. All the cars would ordinarily be replaced eventually, in about 20 years. Advancing that to replace them faster costs an amount proportional to the total. When the capital, backup, distribution costs are counted, wind power costs about five times as much as conventional power and solar power about seven times as much. Hence the green upgrade is the cost to replace all the power plants in the country, times about six. The UX needs about 900,000 megawatt. [12] A new 300 megawatt coal plant is roughly $1 billion. [13] A green energy upgrade would be about $18 trillion. On the other side of the ledger, the US has about $300 trillion worth of fossil fuels that would become worthless. [14] The GDP is $14 trillion. We cannot afford the costs, so the policy would fail. --------------------- 1. http://www.theregister.co.uk... 2. http://www.geocraft.com... 3. http://www.geocraft.com... 4. http://www.currentresults.com... 5, http://www.co2science.org... 6. http://anthro.palomar.edu... 7. http://clivebest.com... 8. http://notrickszone.com... 9. http://paoc2001.mit.edu... 10. http://www.thegwpf.org... 11. http://factspluslogic.com... 12. http://www.eia.gov... 13. http://www.jsonline.com... 14. http://factspluslogic.com...
