"Millions of years data with CO2 peaks tracking the temperature peaks at an average of 800 years, sometimes even less, does not count now man comes in action, right? Do not forget that current 'elevated' CO2 levels are real low compared to historical peaks contained in same data."
The current levels are adressed below.......and they are higher than any in the 400,000 years. So what effect is the current rapid rise having on climate change????
The global temperature changed naturally because of the changing solar radiation caused by variations in the Earth’s orbit around the Sun, the Earth’s tilt and the orientation of the Earth’s axis. These are called the Milankowitch cycles and occur in periods of approximately 100,000, 42,000, and 22,000 years. These are the cycles that cause the Earth’s climate to shift between long ice ages of approximately 100,000 years and warm interglacial periods, typically 10,000 – 15,000 years. The natural warming of the climate was intensified by the increased amount of CO2 in the atmosphere.
“What we are observing in the present day is that mankind has caused the CO2 content in the atmosphere to rise as much in just 150 years as it rose over 8,000 years during the transition from the last ice age to the current interglacial period and that can bring the Earth’s climate out of balance,” explains Sune Olander Rasmussen adding “That is why it is even more important that we have a good grip on which processes caused the climate of the past to change, because the same processes may operate in addition to the anthropogenic changes we see today.
In this way the climate of the past helps us to understand how the various parts of the climate systems interact and what we can expect in the future.” |
