Top Scientists Say: You Are Not the Cause of Global Warming
Posted by iusbvision on October 22, 2007
We have all heard the theory a thousand times: man and his evil industrialization is causing the Earth to warm because CO2 (carbon dioxide) is a greenhouse gas and the exhaust from human activity is the primary cause of global warming and that there is a consensus of top scientists that the theory is true. They tell us that this warming will cause catastrophic effects and we have to act now. There is only one problem, many top scientists are convinced that none of this is true and actual measurements (not computer simulated models) of the Earth and solar system by top scientists demonstrate this beyond reasonable doubt.
Before we examine the technical data it is important to understand how the greenhouse effect global warming theory works. Greenhouse gases settle in a layer of our atmosphere called the troposphere and it is here that the heat that rises from the surface of the Earth gets trapped in atmosphere keeping us all warm. Think of the troposphere as a giant heat mirror or blanket in the sky that reflects escaping heat back down to the surface.
The computer models that global warming alarmists point to tells us that the troposphere is getting warmer at an ever increasing rate because of human generated CO2 causing the excessive greenhouse effect. However, the actual temperature readings of the atmosphere show no such increase in temperature in the troposphere.
Allow me to introduce Dr. John Christie. Dr. Christie is the scientist who is largely responsible for the methods used in measuring the temperature of the atmosphere. Dr. John Christie was awarded a medal from NASA for exceptional scientific achievement in 1991 and in 1996 received a special award from the American Meteorological Society for fundamentally advancing our ability to measure climate. Dr. Christie is also a lead author for the United Nations Intergovernmental Panel on Climate Change (IPCC). He measures climate temperature using satellites and weather balloons.
Says Dr. Christie, “What we have found consistently, in a great part of the planet that the bulk of the atmosphere is not warming as much as we see at the surface and that is a real head-scratcher for us because the theory is pretty straight forward; that if the surface warms the upper atmosphere should warm rapidly. The rise in temperature of that part of the atmosphere is not very dramatic at all and really does not match the theory that the climate models are expressing.”
Dr. Christie continued to say that, “I have often heard it said that there is a consensus among thousands of scientists on the global warming issue that humans are causing a catastrophic change to the climate system. Well I am one scientist, and there are many, that simply think that is not true.”
Dr. Fred Singer stated, “All the climate [computer] models, every one of them, calculates that the warming should be faster as you go up from the Earths surface and go up into the atmosphere. Maximum warming should take place at an altitude of about 10 KM. The observations do not show an increase with altitude, in fact most observations show a slight decrease in the rate of warming with altitude. So in a sense you can say that the hypothesis of man-made global warming is falsified by the evidence.”
Dr. Singer is Professor Emeritus of the Department of Environmental Sciences, University of Virginia and is also the former director of the National Weather Satellite Service.
The idea that human generated CO2 is the cause of global warming is falsified by the evidence in several other ways. One of the most important facts to understand in regards to CO2 is that it is a minor greenhouse gas and that the amount of CO2 that humanity generates is but a tiny fraction of what the Earth generates naturally.
Dr. Timothy Ball, Professor of Climatology from the University of Winnipeg and director of the Natural Resources Stewardship Project tells us that “The atmosphere is made up of a multitude of gases. A small percentage of them we call greenhouse gases, and of that very small percentage of greenhouse gases 95% of it is water vapor and it is the most important greenhouse gas. If you take CO2 as a percentage of all the gases in the atmosphere it makes up 0.54%, it is an incredibly small portion; and then you have to take that portion that supposedly the humans are adding that is the focus of concern and the number gets even smaller.”
According to a BBC documentary on climate change, “More CO2 comes from animals and bacteria which produce 150 gigatons of CO2 each year compared to mere 6.6 gigatons from humans. An even larger source is dying vegetation, but the biggest source of CO2 by far is the oceans.”
Professor Carl Wunsch of the Department of Oceanography, M.I.T. is the author of four major text books on oceanography. States Dr. Wunsch, “The ocean is the major reservoir of where CO2 goes. If you heat the surface of the ocean it tends to release CO2 and if you cool the oceans surface it will absorb more CO2.”
The temperature record shows that man made CO2 levels do not correlate with changes in global temperature, but changes in solar activity and global temperatures often do.
Examine the graph [above] carefully. It shows that most of the warming that has happened in the last 200 years occurred before 1940; well before most industrialization and before most people had used cars. It shows that global temperatures actually decreased from 1940 to 1975, which is the time of the post war economic boom, the highest period of global industrialization in world history. According to the theory of man made global warming the temperatures should not have gone up much before 1940 and should have went up quickly after 1940. Exactly the opposite is what took place.
Says Dr. Syun-Ichi Akasofu, the director of the International Arctic Research Center, “[man-made] CO2 began to increase exponentially in about 1940 but the temperature actually began to decrease and continued ‘til [sic] 1975. We cannot say that CO2 and temperature go together.” Dr. Nir Shaviv of the Institute of Physics, University of Jerusalem states that “there were periods in Earth history when we had three times as much CO2 as we have today or ten times as much CO2 as we have today and if CO2 has a large effect on climate we would see it in the temperature reconstruction.”
Dr. Piers Corbyn, lead climate forecaster for Weather Action (England) said, “None of the major climate changes in the last 1000 years can be explained by CO2.” Dr. Patrick Michaels from the University of Virginia and IPCC author states that “Anyone who goes around and says that CO2 is responsible for most of the warming of the 20th century hasn’t looked at the basic numbers.”
Dr. Ian Clark a leading paleo-climatologist from the University of Ottawa says, “If we look at climate in the geological timeframe we would never suspect CO2 as a major climate driver. You can’t say that CO2 will drive climate. It certainly never did in the past.”
So what about Al Gore? It is right about at this point in any conversation about global warming I have when I am asked, what about Gore’s movie “An Inconvenient Truth”? Gore’s movie is largely centered around two pieces of evidence. The first is those computer models that we discussed earlier that show the ever increasing temperatures in the troposphere that just is not happening in real world measurements. The second is the long graph that Gore claims shows a correlation between global CO2 levels and global temperatures over thousands of years. The graph is from what is called the ice core record. This measurement is taken by drilling into ice glaciers that are many millennia old. The CO2 levels of the atmosphere trapped in the ice can then be compared to the known global temperature records.
According to a BBC interview with Dr. Clark, paleo-climatologists have discovered a link between CO2 levels and temperature, but what Al Gore doesn’t say in his movie is that “the link is the wrong way around.” When the global temperature rises or falls, only after 800 years do the CO2 levels follow. Every ice core record measurement has shown this same correlation.
Global warming alarmists don’t want you to know that global CO2 levels lag behind temperature levels by 800 years and Gore’s own method of comparing CO2 to the global temperatures shows this to be true. The data is clear, warming causes CO2, CO2 does not cause warming; if it did the CO2 levels would have to rise before the global temperature does and the data shows that this just isn’t the case. Says Dr. Clark, “Temperature is leading CO2 by 800 years. CO2 clearly cannot be causing temperature changes, it is a product of temperature levels, it is following temperature changes.”
Below is the graph showing the CO2 levels measured using the ice core method that Gore is so fond of over the last 400,000 years and as you can see the CO2 levels spike about every 100,000 years in what appears to be a natural cycle. There is no way that the CO2 spikes over the last 400 millennia can be explained by man or industrialization. Al Gore and the global warming alarmists are trying to either stop a natural cycle, or exploit it for political purposes. The science has spoken.
