Global warming and solar actvities

    I am new here, and I have a question about the Global warming.
    do you think the global warming is caused mostly by pollution or solar activities of our sun ?!

    Controversial issue this. Ask the IPCC they will say absolutely not, solar activity only plays a very minor role compared to CO2. I've always thought that the variation in the suns output must play a more significant role than they are letting on, as the sun is the only mechanism that heats up the Earth in the first place. And there has been a few observations of global warming on other planets in the solar system that i have collected before, as they seemed an interesting observation;

    This is however holtly disputed, most people think that it is purely due to human activity. I'm still undecided.

    This is still in doubt. In the Little Ice Age, the Sun was in tired condition then the Earth was very cold at the time.
