It is true the earth had a slight increase in temperature during the first forty years of the 20th century. But global warming and cooling is cyclical and there has not been any proof that warming is caused by man-made CO2, which lags years behind global warming. Global warming and cooling correlates with sunspots, and the earth naturally regulates itself.
S. Fred Singer, a climate physicist, and Dennis T. Avery, a senior fellow at the Hudson Institute, have written the definitive book about global warming. They carefully explain the complexities and facts so the average person can understand. It is true the earth goes through warming phases, but they are cyclical and not man made. Climate change is not a dramatic event but something as regular and dull as grass growing. A close look at the evidence reveals that climate change is probably due to variations in the sun's radiation – sunspots. Global warmings and coolings have occurred regularly about every 1,500 years. The earth's temperature increased in the early 20th century, before most man-made emissions began, but stopped increasing in the latter half of the century when man-made emissions were highest.
Higher levels of CO2 are not responsible for the current warming trend. Satellite and high-altitude weather balloon data confirm that the lower atmosphere is not trapping lots of additional heat due to higher CO2 concentrations. It is earth's surface that is warming, and it is warming more rapidly than the lower atmosphere where the CO2 is accumulating.
Global warming alarmists assume that the increase in CO2 is also due to an increase in water vapor. Water vapor makes up about 60% of the natural greenhouse effect, with CO2 only making up about 20%. Minor gases including ozone, nitrous oxide, and methane make up the remaining 20%. If there was only an increase in CO2, the difference in temperature would be minuscule, so alarmists are forced to assume that water vapor is increasing too. North Dakota state climatologist John Bluemle has stated that doubling CO2 levels would have a miniscule effect on temperature. It is true that warmer air can hold more water vapor. But there is no evidence that the water vapor is remaining in the air – contributing to the greenhouse effect – or whether it is raining down more quickly.
Antarctic ice cores reveal that there is a close correlation between CO2 levels and the earth's temperatures throughout the last three ice ages including global warmings. However, CO2 levels have lagged behind the global warmings by about 800 years, evidence that CO2 is not the causal factor. According to Hulburtus Fischer, an environmental physicist, and his research team from the Scripps Institute of Oceanography, when the ocean warms, it releases CO2, stimulating more plant and tree growth. As the vegetation absorbs the additional CO2, it becomes lusher and bigger in size. This process takes approximately 800 years. So in reality, whenever earth's temperatures have risen, things have improved on earth. A two degrees Celsius change would result in more beneficial conditions than now. "The Romans, Chinese and Medieval Europeans all tell us that the last two warming phases of the 1,500 cycle were prosperous times for humanity…The prosperity of the Medieval Warming is apparent to us today through the beautiful castles and cathedrals of Europe, which date mainly from that period. How could these have been built if the warmings were accompanied by the flooding, epidemics of malaria, massive famine, and constant storms assumed by the gloomy advocates of man-made warming?"
Unlike the computer simulation models environmental alarmists rely upon to create artificial worst-case scenarios, evidence shows that the earth has done a pretty good job regulating its atmospheric temperatures. Studies done by NASA's Goddard Space Center and a NASA-MIT study in 2001 led by atmospheric physicist Richard Lindzen found that the ocean's surface temperature always remains at 28-30 degrees Celsius due to self-regulation. When the temperature rises, more water evaporates into the air, which in turn creates more clouds that send cool, dry downdrafts of air that lower the sea temperature. "When the clouds deposit the increased moisture from that rapid evaporation on polar ice caps and glaciers around the world, the ice caps and glaciers will actually grow unless the local temperatures are warm enough to increase local melting."
The United Nations' Intergovernmental Panel on Climate Change (IPCC) is responsible for much of the global warming alarmism. It has been highly criticized by genuine scientific organizations like the International Union for Quanternary Research (INQUA). INQUA is a 75-year old scientific think tank that researches global environmental and climate changes throughout history. INQUA asserts that the IPCC ignored the scientists who produced most of the data and observations on sea level science, substituting computer models which produce "the falsification of scientific observational facts."
The IPCC and its simulated computer models cannot explain why the earth became colder between 1940-1975. The frequently cited landmark 1996 global warming report issued by the IPCC simply omitted the portions contributed by scientists which expressed skepticism about global warming, instead relying principally upon the writings of global alarmist extremists like scientist Ben Santer of the U.S. government's Lawrence Livermore National Library. Sentences like this were deleted from the report by Santer, "None of the studies cited above has shown clear evidence that we can attribute the observed [climate] changes to the specific cause of increases in greenhouse gases."
There is plenty of evidence indicating that the earth has not been warming in recent years. The Indian Ocean's level was higher between 1900-1970 than it is today. The Maldives, 1,200 islands which sit in the Indian Ocean, are 20-30 cm lower today than they were in 1970. Lester R. Brown, an agricultural economist who has made wrong predictions about world famines since the 1960s, claims that First World countries are flooding the Pacific Islands due to greenhouse gases from power plants. In reality, since 1993, the island of Tuvalu has seen ocean levels decrease by four inches.
The environmental extremists' simulated computer models can be manipulated to generate any outcome wished. They are even further askew considering they are based on thermometers located in urban areas where there is a concrete jungle effect, increasing temperatures and overstating surface temperature increases by as much as 40 percent. Using the models' conclusions, there should have been a rise of several degrees Celsius at the poles since 1940. In reality, the temperature at both poles has been decreasing. Temperatures at and near the North and South poles are lower than they were in 1930. This is evidence the Greenhouse Theory is not correct, because manmade emissions began dramatically increasing around 1940. In fact, 97% of the Antarctic has been cooling since the mid-1960's. Alarmists point to the 3% that is warming because that is where most of the scientists and thermometers are, and it reinforces their Greenhouse Theory.
If the earth warms, wetlands won't dry up. They will simply move slightly upslope, as they have in years past when the climate warmed. Similarly, animals will change locations and relocate to areas most conducive to their habitat. By the time Arctic regions have warmed enough to shift penguins and polar bears around, they will begin cooling again and the animals will shift back to their previous habitats, without causing any extinction. Glaciers also naturally shift around, which includes both retreating and growing. Physicist and meteorologist professor Johann Oerlemans of Utrecth University in the Netherlands produced a graph in 2001 which showed that the major glaciers of the world started to shrink around 1850, but by 1940 only half of them were still shrinking, and many of them had started to grow again.
The U.N.'s Kyoto Protocol was little more than a scam designed to punish wealthier countries. It did not enforce restrictions upon big developing countries like China and India, which refused to sign it. The only evidence provided for the Protocol was that the temperature of the earth had increased by .6 Celsius over the last century (conveniently omitting that the increases had mostly been during the first forty years of the century), along with simulated computer models that created any conclusions chosen to be programmed.
Global warming extremists like to point to the "Scientists Statement on Global Climatic Disruption" petition from the group Ozone Action as evidence that a majority of scientists believe man made global warming is occurring. It was signed by 2,611 scientists worldwide in 1996 and sent to President Clinton. But according to Citizens for a Sound Economy, only about 10 percent of the signers had degrees in fields related to climate science – about 260 signers total. The signers included landscape architects, psychologists, a traditionally trained Chinese doctor, and a gynecologist.
On the other hand, these extremists ignore the Oregon Petition, which was signed by more than 17,000 scientists and expressed doubt about man-made global warming. More than 2,600 of its signers have climate science credentials. Global warming extremists tried to discredit it by saying a few of the signers were fake names, but there were only a few and were probably planted there by extremists in order to later discredit the petition.
In 2001, the IPCC issued a report that included a "hockey stick" graph showing global warming trends since the year 1000. The graph eliminated the Little Ice Age which occurred during the 17th and 19th centuries, and exaggerated the increase in global warming in the 20th century, making it appear as if this was the highest hike in global warming in the past 1000 years. This graph was discredited when it was pointed out that the earth's warming in the early 15th century greatly exceeded any warming in the 20th century.
There was also a greater warming at the beginning of the last 1000 years. About the time the Vikings discovered Newfoundland, they also discovered "Vinland," so named in 1001 A.S. due to the widespread growth of grape vines. This area has remained too cold to sustain grape vines, even up until today when environmental extremists tell us we are experiencing a dramatic increase in global warming unprecedented in the last 1000 years.
Sallie Baliunus, an astrophysicist with a degree from Harvard, and Willie Soon, also an astrophysicist, from the Harvard-Smithsonian Center for Astrophysics, looked at 102 studies which analyzed whether the 20th century was the warmest, and found that 78% of them did not. Another four studies found that the earliest part of the 20th century was the warmest – before most man made CO2 emissions.
Global warming alarmists warn that animal species will die out as the earth warms. In reality, not a single species has become extinct due to the .6 percent increase in the earth's temperature over the past 150 years. Most alarmists point to a single species they claim has become extinct due to global warming, the Golden Toad of Costa Rica. In reality, the toad became extinct due to clearing by natives of the lowlands it inhabited. Overall, there are less species becoming extinct today than in the past. The United Nations Environmental Program issued a report in 2002 which found that the world lost only half as many major species during the last 30 years of the 20th century as it did during the last 30 years of the 19th century.
The artificial divide set up by global warming extremists between the underdeveloped countries and First World developed countries falsely portrays industrialized countries as the ones responsible for air pollution. The environmental movement uses an emotional argument to make people feel guilty about its wealth. In reality, "richer people have fewer children, feed themselves with much less land per capita, gradually but largely reduce industrial pollution, generally plant more trees than they cut, do most of the research on environmental preservation, and make most of the investments in actual conservation." Whereas "primitive peoples have never lived in harmony with nature" as the urban legend would have us believe. They have, instead, exploited nature unsustainably because their populations always crept upward to the absolute limits of their resources – and then beyond…today [they] practice slash-and burn farming, cook and heat with wood from trees they don't replant…."
Global warming alarmists never discuss using nuclear power, the only non-CO2 producing energy alternative that would be a cost-effective alternative to today's energy uses. Unfortunately, activist lawsuits have driven up the costs of nuclear regulation. It is possible however; France currently gets about 3/4; of its energy from nuclear reactors. Many of the environmentalists' proposed energy solutions wouldn't work. For example, to convert energy use to rely upon windmills, a landmass the size of South Africa would have to be cleared of all forests in order to install enough windmills. And that wouldn't even cover the cloudy/windless/high-wind days.
There will always be environmental alarmists. In 1975, environmental alarmists warned that the earth was cooling. The National Academy of Scientists issued a report claiming "…a finite possibility that a serious worldwide cooling could befall the Earth within the next 100 years…"
It's better to look at rocks, fossils, and sediment cores as more reliable predictors of climate temperature than simulated computer models. They reveal that there is a correlation between variations in the sun's irradiation and the earth's temperature. When there are larger sunspots, the earth's temperature increases, and visa versa. In addition, some of the increased temperatures may be artificially due to urban heat islands, since the vast majority of higher temperatures have been reported in industrialized areas.
The authors conclude:
Human society should attempt to put binding constraints on human emissions of greenhouse gases only if the advocates of man-made warming can demonstrate three things:
1. That the greenhouse gases are certain to raise global temperatures significantly higher than they rose during previous natural climate warming cycles;
2. That the warming would severely harm human welfare and the ecology;
3. That rational human actions could actually forestall such overheating.
To date, the advocates of man-made warming have not been able to meet any of these minimum requirements. The IPCC's claim to have found the 'human fingerprint' in the Modern Warming was bogus when Ben Santer first altered the science chapter in the IPCC's 1996 report, and it remains bogus today. No one has been able to distinguish natural from man-made warming.
