Global Warming

There is always a thread of global warming or cooling (caused by the sun, natural causes and man) and once it has set in we may not be able to do anything about it.

Blaming humanity might be a bit exaggerated but man cannot continue abusing the environment as we are doing and the damaging actions must be tempered or stopped.

Nature has a critical limit beyond which return would be difficult, man therefore has a duty to protect and preserve nature as far as humanly possible.

The planet will survive a good many more things than the life forms upon it will.

This a copy of a post I put in my previous discussion, hope other dont mind me including it here, just some of my thoughts on global warming. JD

CO2 it seem still hold some interest it peoples minds, feelings of concern or scepticism regarding its affects on the weather? Having read other peoples post in this discussion and others, I would like to make some observations. I personally thought that the earths tilt was the main cause, and this comes about by some natural cause referred to as the Milakovitch Hypothesis, which I believe is the gravitational influences from other masses in the universe. So I would like to approach this discussion from a different angle which goes something like this. The amount of kinetic energy contained within the earths system was created at the time it came into existence, with gravitational force and heat radiation as variables governed by proportion, a plus or minus value on the difference of the incoming and outgoing. We are then left with conversion of energy between gasses, fluids and solids, and if there is no other influence they move into a state of equilibrium. The weather is referred to as having multiple states of equilibrium. This then leads to the statement that past weather pattern have come about naturally without the help of mankind as indicated by proxy records, ice cores etc. This then begs the question, if nature can vary the atmosphere and weather then imitating what nature does naturally has no effect? So if one accepts the possibility that both the variables gravitational forces and heat are a cause of a change in the state of equilibrium, then one could put forward the following hypothesis: With moderate atmospheric temps we have a exchange of warm and cool air mixing between the north and southern hemisphere ensuring wide spread precipitation. As the air temperature rises around the equator it hold more moisture and when cooler air mixes with it precipitation occurs, and energy is dissipated, this stops or minimises the mixing of south and northern hemisphere air, thus leading to heavy storms and heavy precipitation at some latitude moving away from the equator. One could then speculate that as the equator temp rises the front between moist and cool air moves closer to the poles, leading to heavy cloud cover north and south of the heavy precipitation belt, and a new state of equilibrium. Any thoughts on that, I agree that its nothing more than speculation.
