Can we see the mankind future in the Neanderthals past?

Climate change affect Neanderthals life pushing them into their extinction.

Neandertharls disappeared from Europe just after 40.000 years ago. There are many hypothesis of the Neanderthals extinction but one of the strongest idea is they live in a glacial age. Recent discoveries show that the climate of that age was so stressful for our ancestors. Analizing the prey animals found out that they extract until the smallest pieces to feed in the coldest times.

Also, they had changed their behaviour to adapt better to the environment but not all the adaptations always have desirable effects. As we know it didnt't work as good as they thought.

But that can happen to us?

As we saw in the last years the emission of CO2 increase in the atmosphere due to the pollution of amount of factories. That will not induce a glacial age but quite the opposite, an incredible high temperatures and the decrease of the potable water. It seems a terrible environment for us, but it is not something that a crazy people says, even the most qualified scientific assume that. Based on historical levels of CO2 we can see the highest the level of CO2 the lowest the probability to begin a glacial age. Tha occur cause the CO2 hides in the deep of the ocean and only a very low quantity of this gas appear in the atmosphere. So if we want to survive we'll have to adapt better than our ancestors.

But that is only one hypothesis as well as the Neanderthals extinction due to climate change. Another idea of this extinction is that Homo sapiens did it ("us"). So we don't have to discard the hypothesis of another more develop specie can extinct us, but that is another story.
