Actually, it is your car (and my car and the millions of others and the fossil fuel power plants, etc.). If you have clear evidence to the contrary, you could easily publish it in Science or Nature and become famous. I got off of facebook because of anti-scientific posts like this. I hope Steemit doesn't go that route. The evidence that humans are causing the massive warming has been clear for some time. Yes, there are natural cycles, but those cycles are now just blips in the increasing global temperature.
