CLIMATE CHANGE : The Source of Global Warming and IPCC Report and Its Critics

Climate Change - Fact or Fiction?Many readers will be perplexed by the media arguments over whether measures to combat global warming - or as scientists now prefer to call it, climate change - are necessary to forestall a serious threat to the environment, or form part of a politically-motivated scam. What I want to do here is to take a look at the underlying facts.Firstly, let's establish an important point. Al Gore made the famous statement that, 'There can be NO debate' over global warming. He was correct, but not in the sense he envisaged. Debate is the process by which politics proceeds. Science, however, is not politics. Science is not a process of debate. It is a process of making postulates which which fit the observed facts. If a postulate fits the facts, then the postulate is potentially valid. If it does not fit the facts, then it is not valid.Thus we need to exclude all of the emotional propaganda from our minds, and satisfy ourselves as to whether or not the claims of climate scientists fit the observed facts.The human-induced warming theoryFirst, the theory The basis of the global warming postulate is that carbon dioxide (CO2)is regarded a greenhouse gas, because it intercepts some of the infrared (thermal) radiation leaving the earth's surface. This, it is said, increases the surface temperature by trapping the sun's heat. It is then claimed that releases of carbon dioxide from human industry are raising carbon dioxide concentrations to the point where there is a risk of runaway temperature increases, with resultant catastrophic effects on the Earth's ecosystem.Things we do •The greenhouse effect is real•Carbon dioxide is a greenhouse gas•Carbon dioxide intercepts only two small ranges of infrared wavelengths•Thus, it is not a particularly effective greenhouse gas•The relationship between carbon dioxide concentration and heat retention is logarithmicLet's look at these points in more detail. That the Earth is about 32 Celsius warmer than it would be without an atmosphere, is largely undisputed. The airless Moon offers proof of this. Greenhouse gases play a part in this, but exactly how large a part is uncertain.Table of ContentIntroductionClimate Change - Fact or Fiction?The human-induced warming theoryIs there an anthropogenic influence on climate change?What will its effect be???•How do we measure climate change in the past?•How are we predicting climate change in the future?Determining Past Climate Change -Oxygen IsotopesDetermining Past Climate Change -DendrochronologyClimate through the Ages -Long-Term Temperature RecordClimate through the Ages -The last 1000 YearsClimate through the Ages -Recent TrendsClimate through the Ages -Long-Term Temperature Record, ContClimate through the Ages -Recent TrendGlobal Warming Is Not a HoraxClimate Change -Milankovitch Theory -Eccentricity CycleClimate Change -Milankovitch Theory-Precession CycleClimate Change -Milankovitch Theory- Tilt CycleThe Source of Global WarmingClimate Change -Increasing Concentrationsof CO2 and other Green HouseClimate Change -CO2 Feedback mechanismsIPCC (Intergovernmental Panel On Climate Change) Report and Its CriticsSea Level Rise to Be Higher & Faster Than Predicted by IPCCOne Voice, Deaf Ears?
