In an order to avoid the catastrophic change of climate, humanity can not burn out the more than fourth of the known supplies of hydrocarbons on a planet. Critical value – one trillion of tons of extrass CO2. Within the framework of research of environmentalists interested a question about that, what amount of carbon dioxide humanity can throw out in an atmosphere, not causing the increase of middle temperatures more than on two degrees on Celcius. Scientists mark thus, that from the beginning of industrial
revolutions humanity threw out in an atmosphere already 500 milliards of tons of this gas.The calculations of researchers show that critical value – one trillion of tons CO2 (it a number they named the carbon budget of humanity). If extrass will attain this value,
then probability of further neupravlyaemogo rise in temperature will make 0,5 (the model of scientists carried probabilistic character). According to researchers, a bit to secure itself, humanity must throw out no more than 750 milliards of tons of carbon dioxide in an atmosphere.
Probability of catastrophe will make in this case "in all" 0,25, reports New Scientist. The article of scientists appeared in a magazine Nature.po humanity has no more than 20 years information of scientists in case if a safe scenario will be chosen, and no more than 40 years, if a scenario will be chosen,
where a risk is 50 on 50. Calculations were conducted taking into account circumstance that presently extrass are increased approximately on 1-3 percent annually.Scientists mark that new calculations specify on that the purpose of international association must be not only
decline of extrass, but also passing to an environmentally clean industry. We will remind that presently in the world there is plenty of projects on a transition on "net" energy. So, for example, one of variants is introduction of technology of capture
and burial places of carbon (carbon capture and storage – CCS). Within the framework of this technology it is planned to conduct cleaning of extrass of ordinary thermal power-stations from
