The Sun is Responsible for Global Warming

Some Skeptics have said that the sun has been getting hotter and is responsible for global warming. Actually, the sun cooled off drastically starting in 2002, bottomed out in 2009 and started going back up to average in 2010. In spite of that global temperatures did not change. Had the sun not gotten cooler, temperatures would have actually gone up instead of being temporarily paused.

Another point is that if increased sunlight were to be responsible for global warming then all areas of the world would be affected equally. Global warming though is more concentrated in the Arctic regions of the Northern Hemisphere where sunlight is weaker.
