Conclusive. That is the word that matters. These are conclusive findings by our scientists and those who study the planet globally.

...The "roundness", or eccentricity, of the earth's orbit varies on cycles of 100,000 and 400,000 years, and this affects how important the timing of perihelion is to the strength of the seasons. The combination of the 41,000 year tilt cycle and the 22,000 year precession cycles, plus the smaller eccentricity signal, affect the relative severity of summer and winter, and are thought to control the growth and retreat of ice sheets. Cool summers in the northern hemisphere, where most of the earth's land mass is located, appear to allow snow and ice to persist to the next winter, allowing the development of large ice sheets over hundreds to thousands of years. Conversely, warmer summers shrink ice sheets by melting more ice than the amount accumulating during the winter....

The text and graph as before. The graph shows a geological and climate record of 600,000 years. Got that? 600,000 years and what does the text say above? Let me quote it again, "...earth's orbit varies on cycles of 100,000 to 400,000 years," A graph of six hundred thousand years and a cycle of four hundred thousand years. That is what is called conclusive. The finding of scientists, ninety-seven percent of them, have concluded this episode of Earth's warming is outside the bounds of anything experienced before and therefore CONCLUSIVE.

Now I know there are Americans that believe that Earth has only existed about seven thousand years. It would be very difficult to get their minds around such things. That is religious dogma and not science. They don't have to relate to this. The people elected of office at all levels of government need to appreciate the vast stores of information our scientists have accumulated and their findings are conclusive. It is up to the elected officials to act on the conclusions of scientists.
