Unless the 100,000 year earth orbit cycle is understood----no climate discussion will arrive at any factual discussion. Yes the earth is in a warming cycle as we are 50,000 years away from the last major ice age. Any graph of climate temperature that only shows a temperature change over 200 years will be no more accurate than a graph showing 10 minutes of temp changes and concluding what the average daily temp will be, When you wish to reply---first indicate your understanding of the wobble of the earth as it orbits the sun, the amount of co2 that man produces compared with total co2 production each year, the effect of water vapor as a greenhouse gas and methane as a green house gas. This man made climate change is nothing but a ruse by liberals to gain power by scaring ignorant people who do not understand the real causes of climate change over millions of years. Do a search for the Milankovitch cycle--it will give the reader an understanding of the complexity of the problem.


It takes pounds of dumb to believe that man has the power to change the earth's climate

It's CO2. If you write co2 it shows that you do not understand any chemistry.

100,000 year cycles are unimportant when looking at 10 year climate movements.

Nature does indeed produce lots more CO2 than human activity.

CO2 may be rising due to natural phenomenon such as the warming of the surface of the world's oceans but that's a bit of a circular argument. The world's oceans have warmed a bit as the world has warmed a bit. We have pumped out a significant amount of CO2.

CO2 is however the basic stuff plants use to make more plant. It's increased abundance is a fertilizer for the world.

I can see nothing significantly negative from a little warming. A little more CO2 is also a very good thing.

Any look at a 10 year climate data will do as much good as the study of 10 drops of ocean water and the changes in those ten drops as a measure of what is happening in the whole ocean. Such a small sample is of very little value to anyone.

The last major Ice Age was about 13,000 years ago. and before about 1 million years ago ice ages happened about once every 40,000 years. Does the Milankovitch cycle allow for that. And since you started this thread, why don't you explain it so everyone can understand it ? That is what you want, isn't it ?
Wake, how about you ? You support it but won't say why.

The Milankovitch Cycles are very difficult to use to explain a warming period. Firstly because these cycles are 100,000, 41,000, 23,000 and a matching pattern at 19,000 years which is a synchronization of the other patterns.

This was an attempt to explain Ice Ages and synchronizes poorly with the 1,000 warm/cool cycle we have good data on.

What's more, the amount of energy the Sun emits upon the Earth remains the same, only it occurs at different times. For instance: at one extreme it has colder winters and warmer summers, while at the opposite end, warmer winters and cooler summers but the total received energy remains the same.

The climactic variations are so complex that trying to use any one of some 200 different operators is useless.

Does CO2 have an effect? Certainly - at levels of about 200 - 250 ppm. Above that the energy in the absorption bands of CO2 has been absorbed and added CO2 has no effects other than the other normal atmospheric gases. Perhaps less since the energy is spread more widely reducing conduction and convection in these bands only.

So yes, Milankovitch Cycles have a definite effect but they are in some cases totally drowned out by other effects - clouds, atmospheric aerosols, high humidity, the color of the plankton growing in the ocean etc. etc. etc.

CO2 has no effect even at 200 ppm or less. It can't warm the Earth.

For the Milankovitch cycle, Earth is currently moving toward a more circular orbit. All that means is that the difference of intensity of the summers and winters between the northern and southern hemispheres will be less.

... After reading this I like my theory better. You didn't explain why any of the cycles.
