Yea volcanoes have been doing that for along time Bronk ......but it's something happening NOW ....NOW? Volcanoes and other earthly means have been happening since before we got here. Whats the NEW variable thats been causing the change???? Well man's pretty new certainly newer to the earth than volcanoes what could he have been up to lately that could be causing this to happen? As far as we know this wasn't happening before in the 11, 12, 15, 17, 18, centuries especially that we know of. Well what's man done been doing lately? Perhaps the industrial revolution, man's use of creating earthly elements and producing fuels and synthetic compounds that were't here before. Perhaps the earth wasn't ready for that, perhaps the earth could not forsee the effects that man could be having and what he might create. Maybe the earths orbit has changed or perhaps the earth is tilting on it's axis due to other orbital permutation forces, i don't know. The sun is getting older, as the sun burns the rest of its hydrogen gasses through nuclear fussion it creates a lighter compound called i forgot, He3, that is lighter in density than the hydrogen compound that exists on the sun naturally this causes the sun to lose some of it's mass all the time thus losing it's density over time causing the sun to have less gravity and alowing the suns gasseous atmosphere to get father and farther from it's center. In approximately 4 billion years the sun's size will increase and is expected to be at least twice it's size covering up the orbit of the planet Venus, this how Red Giant stars and Super Giant stars are produced and is part of the normal star life cycle. It could be any of these things or other effects we don't even know about. Is it wrong to venture down the road and ask such questions and maybe find the truth. Why do people want to become ignorant of such things and of people who ask such questions? To close your eyes of something denies you the possibility of ever seeing the light. To open them opens them to the possibility of not knowing or knowing. I rather open them and know.
