climate change comes from large natural changes. one giant volcano will dwarf all of what man has put into the air.
All the C02 we are adding to air came from the air during the carboniferous period. what was life like then? warm, humid, and the world supported the largest creatures EVER.
and i mean earth time ever. not just the 100 years we have been creating a record.
Worry about why people tell you what they do, not what they tell you to do.
