Global Warming/ Climate Change

Global Warming has been debated for numerous years and even though a large amount of documentation is available to prove that global warming is real, there is also proof that it is not.
Data has shown that the earth has gone through numerous phases of increasing and decreasing temperatures. There was once and ice age which was then followed by a warmer period.
From the mid 1300s till the early 1400s, there was a period called the Medieval Global Temperature Optimum which was followed by the little ice age. This is just further proof of the cyclic nature of the global climate.
Another issue that shows that there may have been some data manipulation which has greatly influenced the widespread belief in global warming is the chain of emails from the University of East Anglia that was released by a hacker. These emails show conversations between some scientists that were in the process of manipulating data that actually showed a drop in global temperatures.
Approximately every 11 years the sun releases a large amount of energy which bursts out through the outermost layer of the sun and eventually reaches the earths atmosphere. This phenomenon is called a solar flare and is another cause of global temperature increase. However, this occurs in an almost regular pattern, which further proves that a temperature increase doesn't necessarily mean global warming. The solar flare eventually dies down as does the earths temperature.
Global warming, although believed to be existent by many, is simply just another phase of global temperature change that occurs at regular cycles and is influenced mainly by natural causes, not by human activities as most people believe.
