Scientists: the next 80 years humanity will face ruin several times

Over the next 80 years, the human may be exposed to many global disaster. These may be the advent of the disaster, the distance from our most recent will appear in the June 21, 2008. According to foreign media reports, recently have scientists predicted that over the next 80 years, the human may be exposed to many global disaster. World Science report

These may be the advent of the disaster, the distance from our most recent will appear in the June 21, 2008. By then, a number is HZ51, diameter up to 800 meters of asteroid will have the possibility of a collision with the Earth. If this is really a disaster, humanity will likely repeat the demise of the dinosaurs 65 million years ago.

According to the scientists estimate that the probability of the disaster only about 600 000. However, because the asteroid's orbit is so long ago, only to be accurately calculated, so the chance of a collision with the Earth could change.

But at the end of 2011, according to astronomers predict that solar activity will reach peak at this time. During this period, the electrical equipment and navigation instruments work will be seriously affected, people's mood changes. At the same time, strong solar radiation can cause skin cancer incidence of people. It is forecast that solar activity of two peak periods will appear in 2011, and 2012 August. United States Colorado space phenomena research center of Douglas · don't José section pointed out: "we now also can only determine an approximate period of time, however, another 6-12 months, we will give out the Sun to enter the exact time of peak activity. ”

After that, the Sun was also possible outbreak of more violent. The European Space Agency's Pierce · Mayer pointed out that in the last 11 years, the solar Center temperature has increased by nearly doubled. He recalled that the stars in the event of a supernova front often appears similar phenomena. World Science report

According to Pierce · Meyer speculated that Sun might occur in 2013 very violent eruptions and created humankind history rampage of disaster. Once this happens, the Earth's temperature will rise sharply, and ultimately lead to terrible ecological disaster.

By 2020, the global climate will occur very significant changes. At this time, Europe will encounter frequent heavy rains and floods, which hit the local agriculture. While the rest of the world will encounter widespread drought risk. For the people (it is expected that by 2020, the global population will reach 76 billion), rampage food crisis will come.

Sweden physicist Frederick · Rob Rius believes that by 2020, the world's oil production capacity will be reduced-the main reason for this is the main oil producing areas increasingly depleted. And soaring fuel prices will further hit the global economy. Do not rule out the world's major countries for oil resources and expand the possibility of fighting.

To 2029, 13 April, mankind will once again face the threat from space. This time, the diameter up to 400 m 99942 Apophis asteroid from distance Earth 3.5 million kilometres flown. Scientists believe that when people naked only to see the asteroid.

It is estimated that 99942 Apophis and Earth collision probability of one of the 6000 points. This is a very high probability. Therefore, some people even proposed the establishment of a dedicated Fund to develop and implement intercepting the asteroid. World Science report
