It stared 30 years ago it appeared in the news .Indeed, Svante Arrhenius, the pioneering Swedish scientist who in 1896 first estimated the scope of warming from widespread coal burning, mainly foresaw this as a boon, both in agricultural bounty and “more equable and better climates, especially as regards the colder regions of the Earth.”
There were scattered news reports through the decades, including a remarkably clear 1956 article in the New York Times that conveyed how accumulating greenhouse gas emissions from energy production would lead to long-lasting environmental changes. In its closing the article foresaw what’s become the main impediment to tackling harmful emissions: the abundance of fossil fuels. “Coal and oil are still plentiful and cheap in many parts of the world, and there is every reason to believe that both will be consumed by industry so long as it pays to do so.”
It corresponds with the rapid growth and development of the human species over the planet and current period of warm period and it's stated around 11,650 cal years ago before the present.
The specification of the species is known to have been taken place about 350,000 years ago, in the spit for the Netherlands in about 500,000 to 800,000 years ago. And earliest descendants were the H. Erectus some 1.8 million years ago.
Formulation of the neolithic culture of agriculture that was one of the primary forms of the early occupation on the planet started on the 0.0117 million years ago.
Thus about 87% of the planet has nee occupied b the human since there geologic period.
