@Ionus,
In the politest way possible I recently had to ask Parados to please stop wasting my time. He seems incapable of understanding the simplest things - even after they've been explained to him countless times. In this particular case many posters - including me, on several occasions - have patiently explained to him that the sun is so overwhelmingly the source of all temperature changes on our entire solar system that all remaining factors specific to each planet result from positive and negative feedback loops - 1st, 2nd, 3rd and higher derivatives in mathematically chaotic systems.
For the last time I'll make this effort - cover greenhouse gasses in the atmosphere and in the oceans on our planet:
Water vapor: 95 per cent of all greenhouse gasses.
Carbon dioxide: 3.6 %
Other (methane, nitrogen dioxide, and various others including CFCs): 1.4%
Carbon dioxide resulting from man's activities: 3.2% of total CO2, ie 0.12% of total greenhouse gases.
Methane, nitrogen dioxide, CFCs etc traceable to human activities: 0.066, 0.047 and 0.046 per cent respectively.
The planet has been through vast changes long before we showed up on the scene - even Parados can grasp that. We can't affect the climate because we can't affect what the sun does - but at least we can conclusively demonstrate that the IPCC "mathematical model" is a joke. This from a recent article:
Quote:........2.5 billion years ago the sun’s brightness was 20 percent to 30 percent less than it is today (compared to the 2 percent change in energy balance associated with a doubling of carbon-dioxide levels) yet the oceans were unfrozen and the temperatures appear to have been similar to today’s......Interestingly, according to the U.N.’s Intergovernmental Panel on Climate Change, the greenhouse forcing from manmade gases is already about 86 percent of what one expects from a doubling of carbon dioxide (with about half coming from methane, nitrous oxide, freons, and ozone). Thus, these models should show much more warming than has been observed.
