What’s being said below is that CO2 is an insignificant portion of the atmosphere and that man-made CO2 is but a fraction of the overall C02 in the atmosphere. Then the paper goes on to describe all the major factors that really do affect the heating and cooling of the earth. Point being that the trace amounts of CO2 cannot overwhelm these major influences. The focus is which our control over is totally insignificant, when in reality there are much larger and more significant influences that we have no control over.

Regarding a recent article that a big piece of an Arctic shelf had broken off George correctly pointed out that the Arctic ice pack is 30% larger than last years and the melt season is now over. He noted out that ice has the tensile strength of concrete which is basically nil. Then he pointed out that the earth rotates once every 24 hours causing a huge bulge of water to circumnavigate the earth, something us fisherman are familiar with as they are called tides. Superimpose brittle ice over this bulging water and inevitably, it breaks. Its been doing so forever.

Scientists also got a hold of the climate model that produced Al Gore’s now infamous hockey stick chart, they played with the model and found that no matter what data they put in, it always produced a hockey stick.

George Smith, one of the now 500 and growing Global Warming Denier scientists, post this excellent summary paper which really boils down how CO2 has no significant impact on climate change:

Another Dissenter: NZ Scientist: ‘Even doubling or tripling the amount of CO2′ will have ‘little impact’ on temps - Professor Geoffrey G. Duffy - September 4, 2008 nzclimatescience.net

Excerpt: But even doubling or trebling (tripling) the amount of carbon dioxide will virtually have little impact, as water vapour and water condensed on particles as clouds dominate the worldwide scene and always will. [… ]It is also interesting to note that NASA’s Aqua satellite system has shown that the earth has been cooling since 1998. This corresponds with measurements from the Argos sub-ocean probes that the ocean is cooling. This is in stark contrast with the proposals from many ‘climate alarmists’. The solar effect is huge and overwhelming and there must be time delays in absorbance and build up in energy received by earth and ocean masses. But the warmer the Earth gets, the faster it radiates heat out into space. This is a self-correcting, self-healing process. […] The sun directly drives the El Nino–El Nina current motions that drive temperature changes world-wide. The sun sets up evaporative cycles, drives larger air and water currents or cycles, and changes weather patterns and therefore climate change. The varying degrees of lag and out-of-phase changes cause periodic oceanic oscillations. Even over our lifetime we have observed many weather pattern changes where we live. But what we observe (the ‘effect’) in a relatively small time-span cannot honestly be connected directly to any supposed ‘cause’ without investigating all the mechanisms that cause change. It is so easy to grab onto the notion that the increase in fossil-fuel burning and subsequent growth in carbon dioxide in the atmosphere is directly the major cause. Even from season to season we see snow and ice-covered mountains thaw, and massive areas of the Antarctic ice shelf melt, but in just 6 or so months they are restored. We are not alarmed at these annual changes! So why can’t we see that climate changes occurring all over the world now (not as big as these dramatic annual changes) are simply similar but on a larger time-scale. We have the ice-core and sea-bed core evidence at least to show us that this has happened in recent centuries. These are in harmony as to changes in CO2 with time and variations in temperature over time. There is no indication that one causes the other! History also tells us that there have been significant cooling periods over the last 1,000 years. […] Unfortunately a lot of estimates and predictions are strongly based on theoretical computer models. Many now even trust models and their ‘theoretical results’ more than actual measurements and facts from reality. Computer analysis requires that the earth be ‘cut’ into small, separate areas (actually volumes), each being analysed for heat input/outputs and other gas/vapour fluxes. Even so the computational analysis domain size (basic computer grid elements) is huge, 150km x 150km by 1km high, with the current computer power. It is so large that the effects of even the very large clouds are not individually included; and that includes clouds in our visual horizon. The spatial resolution is therefore very poor. […] Warming is not occurring everywhere at once and hence ‘global warming’ is a misnomer. So what are the key players in ‘Climate Change’? The major driver is the sun. Warming depends on the sun. Cooling is due to the lack of sun’s energy. Radiant energy enters the earth’s atmosphere. Air (on a dry basis) consists mainly of nitrogen 78.08% and oxygen 20.94%. Of the 0.98% remaining, 95% of that (ie 0.934%), or almost all is the inert gas argon. Carbon dioxide CO2 is a trace. It is less than 400ppm (parts per million) or 0.04% of all the atmosphere (on a dry basis). Surprisingly, less than a fifth of that is man-made CO2 (0.008% of the total), and that is only since the beginning of the industrial era and the rapid increase in world population.

CLIMATE CHANGE – The real causes

Climate is always changing, and always will. There are seasons. There are day-night (diurnal) cycles. At any one location, heat energy from the sun varies during the day. Energy from the sun is affected by local conditions and clouds. Heat absorption depends on whether it impacts water or land … and even then, the type of land (desert, forest, snow covered land), or the layout of the land (continental masses, or islands surrounded by seas). In some parts of the world temperatures are climbing on average, and in some areas they are dropping. Warming is not occurring everywhere at once and hence ‘global warming’ is a misnomer.
