At many times in the past, the earth's climate has been warmer than it is today. During the period known as the Holocene Climate Optimum, global temperatures were about two degrees Celsius, or about four degrees Fahrenheit, higher than they are today. During the Holocene Climate Optimum, warmer temperatures and an associated increase in rainfall facilitated the development of agriculture, village communities, and eventually cities by humankind in many parts of the world. The increased global temperatures of the Holocene Climate Optimum warmed the world's oceans, causing increased evaporation, creating more clouds and storms, and ultimately increasing rainfall throughout the Tropical, Subtropical, and Temperate zones encircling the earth. During the Holocene Climate Optimum, California, the southwestern and southern USA, the Mediterranean region, the Middle East, the Ukraine, India, China, and northern Africa all recieved more rainfall than they do today. During the Holocene Climate Optimum, the Sahara desert became a lush savannah punctuated with rivers and lakes that supported elephants, giraffes, zebras, hippos, crocodiles, humans, and the cattle the humans had domesticated. During that time, agriculture spread from the Middle East into Europe, rice cultivation spread throughout east Asia, and maize, bean, and squash cultivation spread throughout Central America. The global warming of the Holocene Climate Optimum also caused global sea levels to rise by about two meters, or nearly seven feet. Evidence for that rise in global sea levels has been found in many places, including southern Mesopotamia and in numerous five thousand year-old beaches and coral deposits found throughout the world which are now standing two meters above the present sea level. In the current hysteria about Global Warming, or 'Climate Change', as it is now being called, the emphasis has been entirely placed on the predicted undesirable effects of Global Warming, and the possible benefits of Global Warming are very seldom mentioned. Al Gore, James Hansen, and the other Jeremiahs of Global Warming or 'Climate Change' warn us about catastrophic rises in sea levels which will inundate major cities and about chronic, severe droughts which they claim will dessicate and devastate most of the major agricultural zones of the earth. The geologic evidence from the Holocene Climate Optimum proves that Global Warming will indeed raise global sea levels with catastrophic effects on major cities and low-lying districts throughout the world. However, the evidence from the Holocene Climate Optimum also shows that Global Warming should improve global agriculture by warming and widening the earth's Tropical, Subtropical, and Temperate zones, and by increasing rainfall throughout the world. The loss of some major cities to rising sea levels will certainly be traumatic, but the loss of those cities will be offset by an increase in agricultural production, forestry, and grazing areas throughout the world. The increase in agricultural, timber, and livestock production which would result from an increase of two degrees Celsius of Global Warming is badly needed in our increasingly over-populated world. Plants breathe CO2; they require CO2 to live and they thrive on it. Many professional growers pump CO2 into their greenhouses to increase plant production. Numerous land and satellite-based studies have shown an increase in global biomass during the time period that is associated with Global Warming. According to NASA scientist Ramakrishna Nemani, “Between 1982 and 1999, twenty-five percent of the Earth’s vegetated area experienced increasing plant productivity—a total increase of about six percent.” Al Gore, James Hansen, and the other prophets of Climate Change catastrophe never mention the actual and potential benefits of Global Warming. Why is that? Isn't science supposed to be about objectivity? Al Gore has invested heavily in carbon credit brokerage firms. For Gore, there is a financial profit to be made from promoting Global Warming alarmism. Gregory Fegel

Dear Benny,The measured global temperature record which started around 1856 shows that the Earth was in a warming cycle until around 1880. The CO2record shows that CO2 was increasing by about 0.21ppmv/year over this period.During the cooling cycle which followed from 1880 to 1910, the CO2 concentration increased at a rate of about 0.30ppmv/year.The next warming cycle from 1910 to 1942 saw a dramatic increase in global temperature, but the rate of increase in CO2 concentration only grew to 0.33ppmv over this time period.The well documented global cooling period from 1942 to 1975 that had the world concerned about an impending return to the equivalent of the Little Ice Age, had a contemporaneous rise in atmospheric CO2 that equated to 0.63ppmv/year; almost twice the increase in CO2 of the precious warming cycle.During the warming that took place from 1975 to 1998, the rate of CO2 increase took another dramatic jump to 1.54ppmv/year, but this was followed by an increase to 1.91ppmv/year that we are currently experiencing during the present ongoing cooling cycle.Each successive cooling cycle has had an increase in the rate of CO2 growth over the previous warming cycle, indicating that there is no possible correlation of CO2 with global warming.In 1988 Hansen et al published a paper "Global Climate Changes as Forecast by Goddard Institute for Space Studies Three-Dimensional Model" in the Journal of Geophysical Research that introduced a "CO2 forcing parameter".This parameter had no actual physical basis, but was merely based on the assumption that a 100ppmv increase in CO2 was directly and primarily responsible for the measured increase in global temperature of 0.6 °C that had been observed over the past century.This assumption ignored the fact that over this time period there was both cooling and warming concurrent with rising CO2 concentration, and considering that this paper was published just 13 years after a 33 year cooling trend that also had a concurrent increase in CO2 concentration there is no possible valid rational for this assumption. Essentially in the 46 year period from 1942 to when the paper was published in 1988, there were 33 years of cooling and only 13 years of warming concurrent with increases in CO2, yet the models used a forcing parameter that directly related only warming to CO2 concentration increases.With no basis in fact, this parameter is entirely a fabrication, and the projections of climate models that are based on this fabricated parameter are also meaningless fabrications.In addition to the fabrication, there is a bit of scientific fraud in the creation of this CO2 forcing parameter.The Earth had been warming since the Little Ice Age at a rate of about 0.5 °C/century. The temperature value that went into determining the CO2forcing parameter was 0.6 °C, with the difference from the 0.5 °C/century value likely due to the urban heat island effect. Even if this difference was directly due to CO2 increases, the difference between the observed temperature and the natural warming since the Little Ice Age is only 0.1 °C but the full 0.6 °C was used to fabricate the forcing parameter.It seems that one fabrication leads to another, and when it became obvious that the natural warming of 0.5 °C/century since the Little Ice Age demonstrated the obvious deficiency in this forcing parameter of the climate models, the MBH98 temperature proxy also known as the "hockey stick" was fabricated to remove the Little Ice Age and allow the full 0.6 °C temperature increase to be related to CO2 increases.Considering that the climate models are the only support for the AGW premise, and the AGW premise is the only support for the climate models, exposing this simple fabrication is all that needs to be done to put an end to this circular argument that forms the basis for the entire climate change lunacy.Norm KalmanovitchCalgary Canada
