Hi,
I am new here, and I have a question about the Global warming.

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