The Norwegian scientists ,working under direction of Bjorn Jamtveit from University of Oslo, approve, that have found a source of the gas which has become by the reason of global warming of a climate on our planet 55 million years ago.
According to the accepted hypothesis, the sharp increase in average temperature at the Earth has led to occurrence of new kinds of mammals, including, ancestors of primates i.e. methane “bombs” at the bottom of the sea promoted a birth of people The average temperature then has grown on five degrees of Celsius that meant occurrence of huge new territories, suitable for settling by animals.
Most likely, scientists agree in opinion, that “hotbed effect” has been caused by emission of huge weight of carbonic gas in an atmosphere, but there is no uniform theory, whence it could undertake.
By one of theories, carbonic gas was formed as a result of disintegration of the methane hidden in the form of hydrate (the frozen mix of water and methane) at a sea-bottom. Thus ,reaction of disintegration could be provoked by falling of a comet or an asteroid. The Norwegian researchers consider, that the initial push to irreversible process was given by the lava which has pulled out from bosom of the planet. In favor of the given assumption speaks the hydrothermal muzzles found out in the Norwegian sea , which from gas could be pulled out, millions years ago. Norwegians have found that, theoretically, can be the answer
However the put forward hypothesis at once had opponents. The matter is that the breeds ,found by control of Bjorn Jamtveit, contain a plenty of an isotope of carbon-12 , whereas in case by heating of a lava they should contain carbon-13. Norwegians, however, consider, that the similar situation speaks simply about horrible capacity of reaction and about enormous volumes of the gas thrown out.
Calculations show, that under certain conditions, small local warming or splash of volcanic activity nearby was enough , to hydrates have started to decay intensively, throwing out metane and carbonic gas. The slice of the hydro-methane ice simultaneously burns and thaws droplets
In fact it is important to mankind to understand, how the little changes of a climate can provoke extraordinary changes in it.
