The modern cause of climate change is due to the harmful smokes comes out from the factories, vechiles, companies etc. And it is also due to global warming.

I would say modern lifestyle causes of climate change.

The main cause of Global "Warming" is the $$Billions of Taxpayer dollars that are made available to so-called 'Scientists to provide "studies" that perpetuate the Scam called Catastrophic, Man-made, Global Waming.

If the funding is pulled, then "Global Warming" will disappear.......I guarantee it!!
