Major Reasons of Abnormal climate
1. Solar Radiation
Solar radiation is a major cause of climate change.
We are usually 10 to 100 years of life has a timescale. However, for centuries known as sunspot fluctuations and the volatility of these sunspot cycle (11 years) impacts of climate change. 80 years of the 11-year cycle sunspots affect the timescale of climate change.
In the 1600s, sunspots virtually disappeared cycle, which is affiliated with the Little Ice Age. Warming of the 20th century, and also the length of these sunspots are associated with the change.
However, other mechanisms, without any analysis of the variation of only black dots are limitations will be described in climate change.

2. Milankovitch cycle
Milankovich cycles are cycles in the Earth's orbit that influence the amount of solar radiation striking different parts of the Earth at different times of year. They are named after a Serbian mathematician, Milutin Milankovitch, who explained how these orbital cycles cause the advance and retreat of the polar ice caps. Although they are named after Milankovitch, he was not the first to link orbital cycles to climate. Adhemar (1842) and Croll (1875) were two of the earliest.
The major cycles of the Earth's orbit
The influence of these cycles on insolation (INcident SOLar radiATION) at different latitudes has been calculated by Berger (1991), and Laskar (1993). Below is Berger's solution for 65 degrees north latitude from the present to 1 million years ago. In the Northern Hemisphere, peak summer insolation occurred about 9,000 years ago when the last of the large ice sheets melted. Since that time Northern Hemisphere summers have seen less solar radiation.

3. Global warming
The climate is changing. The earth is warming up, and there is now overwhelming scientific consensus that it is happening, and human-induced. With global warming on the increase and species and their habitats on the decrease, chances for ecosystems to adapt naturally are diminishing.
Many are agreed that climate change may be one of the greatest threats facing the planet. Recent years show increasing temperatures in various regions, and/or increasing extremities in weather patterns.
This section looks at what causes climate change, what the impacts are and where scientific consensus currently is.

4. El Nino Southern Oscillation
An El Niño event begins as surface pressure increases in the western Pacific and decreases in the eastern Pacific. This air pressure reversal weakens, or may even reverse the trade winds, and results in an eastward movement of the warm waters that had accumulated in the western Pacific.
