Why There Is Global Warming Essay

WHY THERE IS GLOBAL WARMING
People in the USA, are being told by the U.S. government and media that global warming is man-made. If that is true, how can the government and media explain the high temperatures the earth has experienced in past years when there were far fewer people? Let us look back in the world's history: for example, between roughly 900AD and 1350AD the temperatures were much higher than now. And, back then there were fewer people, no cars, no electric utilities, and no factories, etc. So what caused the earth's heat? Could it be a natural occurrence? The temperature graph at the bottom of this article shows the temperatures of the earth before Christ to 2040.
In the book THE DISCOVERERS published in February 1985 by Daniel J. Boorstin, beginning in chapter 28, it goes into detail about Eric the Red, the father of Lief Ericsson, and how he discovered an island covered in green grass. In approximately 983AD, Eric the Red committed murder, and was banished from Iceland for three years. Eric the Red sailed 500 miles west from Iceland and discovered an island covered in GREEN grass, which he named
Greenland. Greenland reminded Eric the Red of his native Norway because of the grass, game animals, and a sea full of fish. Even the air provided a harvest of birds. Eric the Red and his crew started laying out sites for farms and homesteads, as there was no sign of earlier human habitation.
When his banishment expired, Eric the Red returned to congested Iceland to gather Viking settlers. In 986, Eric the Red set sail with an emigrant fleet of twenty-five ships carrying men, women, and domestic animals.
Unfortunately, only fourteen ships survived the stormy passage, which carried about four-hundred-fifty immigrants plus the farm animals. The immigrants settled on the southern-west tip and up the western coast of Greenland.
After the year 1200AD, the Earth’s and Greenland’s climate grew colder; ice started building up on the southern tip of Greenland. Before the end of 1300AD, the Viking settlements were just a memory.

This is from the book EINSTEIN’S
UNIVERSE, Page 63, written by Nigel Calder in 1972, and updated in 1982.
"The reckoning of planetary motions is a venerable science. Nowadays it tells us, for example, how gravity causes the ice to advance or retreat on the Earth during the ice ages. The gravity of the Moon and
(to a lesser extent) of the Sun makes the Earth's axis swivel around like a tilted spinning top. Other planets of the Solar System, especially Jupiter, Mars and Venus, influence the Earth's tilt and the shape of its orbit, in a more-or-less cyclic fashion, with significant effects on the intensity of sunshine falling on different regions of the Earth during the various seasons. Every so often a fortunate attitude and orbit of the Earth combine to drench the ice sheets in sunshine as at the end of the most recent ice age, about ten thousand years ago. But now our relatively benign interglacial is coming to an end, as gravity continues to toy with our planet."
The above points out that the universe is too huge and the earth is too small for the earth’s population to have any effect on the earth’s temperature. The earth’s temperature is a function of the sun’s temperature and the effects from the many massive planets in the universe, i.e., “The gravity of the Moon and (to a lesser extent) of the Sun makes the Earth's axis swivel around like a tilted spinning top. Other planets of the Solar System, especially
Jupiter, Mars and Venus, influence the Earth's tilt and the shape of its orbit, in a more-or-less cyclic
