The warming period after the last Ice Age began 35 thousand years ago. But there were world shaking events?

Question

after that that effected life on this planet. We know of civilations going back to 6 thousand years, nomads going back 11 thousand years, and modern man going back 100 thousand years. Do you think there were advanced civilations long before 6 or 11 thousand years ago? Use your imagination and imagine what they were like and imagine where they would of lived if not the entire world. Since there is no record of them imagine what could have erased any records. Looking forward to your responses.

Answer 1

I'm not too sure of your time lines as the last Ice Age only ended about 15-12 thousand years ago, but it is perfectly possible for civilisations to have pre-dated this time.

During an Ice Age sea levels fall as a large proportion of the planet's water is frozen into the glaciers. Therefore any towns would have probably been built on the planes that are now under water following the big thaw. I think such a town may have been identified off the coast of India.

Answer 2

It was a natural warming cycle. As it became a little warmer, decay process increased and produced more CO2 which increased the warming. This is greatly oversimplified, but the basic gist. The difference is now were are actively pumping giatons of CO2 into our atmosphere that was buried deep in the earth as fossil fuels. It was taken out of the atmosphere and no longer influenced the climate. The climatologist do consider the natural cycles of warming and cooling. They consider the physics involved with the earth's weather system that produce theses natural cycles and have re-created these natural cycles using the laws of physics. The consider the amount of incoming solar radiation, the effects of clouds and oceans,, the composition of atmospheric gases, changes in land cover and lots of stuff like that. They are able for predict what the climate in the past has been fairly well and calibrate their equations to match well. Then they predict what the climate in the future looks like. They look at our rates of emission of green house gases, land changes, increase solar radiation and such after the model is calibrated to account for natural cycles. The evidence is over-whelming - the speed with which the climate is changing is increasing. In recent years, there have been signals emerge - greening of the high latitudes and polar ares earlier, melting ice and glaciers, accelerated rate of rising sea-level (water expands when heated - not just ice melting). There is no dispute this is occurring. It is fact. The dispute among non-scientist is "what's the cause?" Many are still at "is it occurring?" Natural variation and solar activity are considered and human activity appears to explain most of the problem. The majority of scientist feel this way.
