Global warming is mainly caused by greenhouse gas emissions resulting from human activities; however, current climatic variations may be affected "around 15% or 20%" by solar activity," according to one researcher.

In the past, the sun was the main external agent affecting climate change on Earth, together with the effects of volcanic explosions and internal factors such as ocean currents.

"If man had never started burning fossil fuels, the sun might have been the only agent regulating the climate until the next glaciation," he said.
