Global Warming
What is Global Warming?
The earth is getting warmer. This warming can occur as a result of natural factors or human activity - or both. But warmer, compared to when? Current sea-surface temperature has risen in the last few years to the 3,000-year average.

To raise the earth's temperature requires adding energy in the form of heat. Where can such energy come from? A build up of certain gases that do not allow heat from the sun to leave the Earth's atmosphere would certainly raise the earth's temperature. These heat trapping gases are called "greenhouse gases," and are the chief cause for the increase in heat retention of the atmosphere. Most scientists believe that human activity is the cause of increasing gases, resulting from burning of fossil fuels.
However, a few scientists say that warming could be due to natural causes. Still other scientists claim that the evidence for warming is not convincing. The temperature sampling around the world is incomplete, especially in very cold areas that are inaccessible. For every iceberg that melts, new ones are forming.
Global Warming Natural Causes
The gases that are natural causes of global warming are also called "greenhouse gases." Although the gases are one of the natural causes of global warming, humans add to them by deteriorating the ozone layer and burning too many fossil fuels.
Natural Cause Of Global Warming Through The Ages.
The scientific explanations of the natural causes of global warming through history are included in the following:
1. The sun spots are exploding -raising the heat
2. Large eruptions in the major volcanoes on the earth - increasing gases and damaging plants
3. The orbit the Earth takes has changed - movement to or from the sun
4. The Earth is different when compared to how it sits near the sun -changes the temperature up or down
5. Meteors caused explosions as they made contact with the Earth - who knows?

Truthfully, the natural causes of global warming are a result of the changes in the Earth itself. It is constantly changing and in an evolutionary state. There is evidence to suggest that even without the intervention of human involvement, global warming would probably be occurring anyways.
