A few interesting facts about the ice ages of the Earth (including the current one)

Despite the panic talk about global warming, our planet, in fact, returned to the typical climate of the Earth. This may seem strange, but we are living in an ice age, which means that the temperature of the planet and the size of the ice caps at the poles, perceived by us as normal, in fact, a significant deviation from the norm.

Here are a few facts you should know about the Earth's ice ages:

The Earth has already experienced at least five major ice ages;
Throughout its history, the Earth was ice-free even in high latitudes for 85% of the time;
The first ice age on Earth occurred about noon in the 24-hour clock of geological time;
The last time the Earth was completely, from the poles to the equator, covered in ice 800 million years ago. The beginning of the end of this period is the increase in CO2 in the atmosphere and, as a consequence, increased volcanic activity;
Climate changes during the ice age are gradual - sudden cooling when it does not happen, just beginning to fall more snow. Li >
- Our geological period, Cenozoic era or "Age of Mammals," began 65 million years ago;
- At present, the world is dominated by so-called quaternary glaciation, which started this about 2, 6 million years ago;
- Every 100 thousand years, it becomes a little warmer by about 40 thousand years, and then he comes cooling;
- The conditions leading to the present climate, there were about 40 million years ago, It all began with the isolation of Antarctica;
- The current ice age will end when the ice caps at the poles will melt rapidly. Does this contribute to humanity or not - is not so important in the life of the world-wide because it will happen in any case.
