Today, the ground below. Maybe. If you do not believe in it, you can read about the possible and impossible doom here. 20 December 2012 kl.

It's probably very few of us who have emptied the account card and put the job up in the expectation that the earth goes by today. But the world fills doomsday interpretations of the Maya calendar quite a lot.
- It may come with great force - up to 300,000 kilometers per hour. When an ice cube comes with so much speed, the more energy in that the impact of just a relatively small lump of ice is equivalent to more than a nuclear bomb. And we are talking about just the medium comets, they have the force of millions of atomic bombs that are triggered immediately when it hits, he told BBC News.
- The actual impact will trigger huge fireball that makes everything for hundreds of kilometers away instantly melts. But there will also be creating a pressure wave, which runs all around the fighter 2 the world and pretty much blows everything away. Dust and other material the fighter 2 will be lifted up in Earth's atmosphere and create a thick and opaque cloud cover that makes that no sunlight down to earth.
- Within the next half a billion years the radiation from the sun will be so great that the evaporation from the oceans are much larger. There are tropical conditions anywhere on the globe. Water vapor is a very potent greenhouse gas, and it leads to further evaporation. There may be a chain reaction in which water evaporates, and we will go around in a pressure cooker. There is no life that can cope with, he says.
But even he is worried that humanity will be wiped out in a moment. - It is so far in the future. But we are pretty sure that it will happen, he told BBC News. Epidemics can not make us extinct
But this is really not the case, says Kari Mølbak who is Chief of State Seruminstitut.For no bacteria or virus is really interested in killing its host to death. They will live on. And the most dangerous are the ones that kill quickly.
- People will also isolate themselves if an epidemic breaks out. They will live on the food that they can find locally. And an airborne the fighter 2 Ebola virus in American movies is not realistic. The least dangerous viruses are those who live the longest, he adds. If all the ice melts .....
Good enough to rising global sea levels rise by 75 meters if all the inland ice in Greenland and Antarctica are melting. So will the people who live on flatter land, escape to the higher ground - and then there will be considerably less space to be on all of us. It will of course the fighter 2 not the entire world population to extinction, but many people must be significantly less space and it can be equal to wars and struggles for space. the fighter 2 It does not get much hotter
But according to Niels Aage Batch Knudsen, no projections suggest that. The estimated measurements suggest the fighter 2 that as it may be four degrees warmer if we do not get a grip on CO2 emissions. If temperatures rise by four degrees, the water will rise by one meter. If we do not get a grip on our CO2 emissions, temperatures can rise more. But:
- There is nothing to suggest that it will be warmer than it has been before. the fighter 2 The hottest time we've had is 120,000 years ago, when it was just a few degrees warmer than today, and the oceans were seven meters higher, says Niels Aage Batch Knudsen BBC News.
