For generations, we have assumed that the efforts of mankind would leave the fundamental equilibrium of the world's systems and atmosphere stable. But it is possible that with all these enormous changes (population, agricultural, use of fossil fuels) concentrated into such a short period of time, we have unwittingly begun a massive experiment with the system of this planet itself...the increase in the greenhouse gases...has led some to fear that we are creating a global heat trap which could lead to climatic instability.

With unrivalled activity.. [he] concentrated the most varied and most complicated functions of government in his own person. He himself watched over the distribution of grain, selected the jurymen, founded the colonies.. regulated the highways and concluded building-contracts, led the discussions of the senate, settled the consular elections - in short; he accustomed the people to the fact that one man was the foremost in all things, and threw the lax and lame administration of the senatorial college into the shade by the vigour and dexterity of his personal rule.
Theodor Mommsen
The effectiveness of any model used to describe and understand behavior of a particular system as a whole ultimately depends on the degree to which that model accurately represents that system. Nevertheless, there have been and are situations in which application of deterministic or animate models to social systems have produced useful results for a short period of time. However, in a longer run, such mismatches usually result in less than desirable results because critical aspects of the social systems were omitted in the less complex model that was used.

Nobody who has lived through the rise of the violent anti-Semitism which led to Hitler can refuse Mrs. Thatcher admiration for her courageous and outspoken warning. When I grew up in Vienna the established Jewish families were a generally respected group and all decent people would frown upon the occasional anti-Jewish outbursts of a few popular politicians. It was the sudden influx of large numbers of Galician and Polish Jews [during World War I] ... which in a short period changed the attitude. They were too visibly different to be readily absorbed.
Friedrich Hayek
The same Being that fashioned the insect, whose existence is only discerned by a microscope, and gave that invisible speck a system of ducts and other organs to perform its vital functions, created the enormous mass of the planet thirteen hundred times larger than our earth, and launched it in its course round the sun, and the comet, wheeling with a velocity that would carry it round our globe in less than two minutes of time, and yet revolving through so prodigious a space that it takes near six centuries to encircle the sun!
Henry Brougham, 1st Baron Brougham and Vaux
The mathematical thermology created by Fourier may tempt us to hope that, as he has estimated the temperature of the space in which we move, me may in time ascertain the mean temperature of the heavenly bodies: but I regard this order of facts as for ever excluded from our recognition. We can never learn their internal constitution, nor, in regard to some of them, how heat is absorbed by their atmosphere. We may therefore define Astronomy as the science by which we discover the laws of the geometrical and mechanical phenomena presented by the heavenly bodies.
