the sun is the main cause of global warming because every 100 years the sun moves closer to the earth heating up our atmosphere even more and in 5,00000000 years the sun will explode and desroy the universe that we call home

Barry's Response - Thank you Emily, for the insight and cute drawing. For more about the Milankovitch cycles, in which the earth's proximity and orientation to the sun change by regular patterns, see this article I've written.
