Scientists have found out correlation between change of a climate and activity of the human almost hundred years ago. The first real steps going on struggle against global warming have been undertaken only three decades ago. The public has become interested about this problem recently. The first measurement of quantity of carbonic gas in an atmosphere have been directed on 1760 - even earlier of the beginning of industrial revolution. In 2000 the world industry has thrown out in an atmosphere in 6.5 times more carbonic gas than in 1900. In comparison with 1760, concentration of carbonic acid in 2000 has increased plus one-third.
1827th French scientist Joseph Furrier has published work in which he was specified, that gases in the atmosphere can uphold rise in temperature of a terrestrial surface, and that if the Earth lose the atmosphere on the Earth would be much colder.
1859th Irish scientist John Tyndall has discovered, that some gases block infra-red rays. He has come up to conclusion, that change of concentration of gases in the atmosphere is able to change a climate.
1896th Work of the known Swedish physicist (in the future - the Nobel prize winner) Svante Arrenius named ” Influence of carbonic acid in the air on the surface temperature ” is published. In it , for the first time, has been specified that world temperatures depend on a level of concentration of carbonic gas in the atmosphere and that †if quantity of carbonic acid double- the terrestrial temperature will grow 5 degrees on a scale of Celsiusâ€. During that time the majority of scientists have a tendency to agree that changes in a climate occur very slowly, and the humans are not in a situation to influence on them. This work of Arrenius has been forgotten for some decades.
