NATURAL CLIMATE CHANGE
Is a climate change caused by the existence of natural processes without any human intervention. Natural climate changes generally occur on a large scale. Human intervention generally results in small-scale changes, although it is not likely to occur on a large scale.
Some natural climate change theories:
1. THE CONTINENTAL THEORY OF DRIFT
The theory is relatively new Also called the theory of plate tectonics "plate shifts lead to changes in ocean currents which subsequently alter air circulation and then shift the climate." Slow shift does not change in small scale
2. THE THEORY OF THE MOUNTAIN OF THE MOUNTAIN
"volcanic eruptions give off dust (in large quantities) to the floating stratosphere and cause a decrease in the amount of solar radiation energy received by the earth causing a decrease in" Eruption of the mountain in the past can be examined from sea sediments, the conclusion eruption of mountains began to increase in the Pleistocene era
3. THEORY OF ASTRONOMY
By Milankovich Based on changes in earth motion as beer follows:1. Changes in the shape of Earth's orbit around the sun2. Changes in the angle of the earth's axis to the ecliptic plane3. Changes in the axis of the earth's axis due to precession
The shape of the earth's orbit to date is described as an ellipse with an average distance from the sun / center 150jt km This shape changes repeatedly over a period of 90,000-100,000 years to re-circle If the orbit is in a circle, the solar radiation received by the earth reaches 20-30% more than when the elliptical orbit is in the aphelium position As it moves around the sun, the axis of the earth forms a 23.5 * angle to the ecliptic plane This angle is changing slowly for 41,000 years from 22.1 * to 24.5 * Because of the change, the part facing the sun also changes The revolution of the earth also has precession, now the earth's axis leads to a recurrent star or star of every 26,000 years Changes in the shape of the orbit, the axis of the earth axis and changes in the direction of the earth's axis resulted in changes in the amount of solar radiation received by the earth Climate change due to astronomical factors lasts for a very long time

4. THE THEORY OF SUNFLOW CHANGE
The radiant energy of the sun is deemed to change
Explosions on the surface of the sun are uneven
There is a high temperature (6.000 * c)
There is a low temperature (4800 * c)
In dark temperature, darker look is also called sunspot stain matahati
The more stains, the lower the temperature, the less energy emitted
These solar stains have periodic cycles (cycle)
There is an 11th annual, 2nd year called daur hale (hale cycle)
There is an annual 80 called gleissberg cycle (gleissberg cycle)
The change of the stain resulted in a change of activity that caused a change in the amount of energy received by the Earth which resulted in changes in the Earth's magnetic field which subsequently changed the global atmospheric circulatory system
One of the most natural climate change takers is the el nino and la nina storms.
