None. Mans influence on climate is minimal at most. Temperatures have been going down for the last 20 years or so.
Umm....no.

That chart would suggest it's been going down for the past decade, if you assumed the tail end continued. Best to use a more up to date chart:
But that does suggest it hasn't changed much in the past 10 years.
Yeah, that's the most up to date chart I could find in my ~30 second Google search.
It has leveled off in recent years, but it still is a 0.6 degree anomaly. And I would attribute the stability to increased climate change regulations and environmental precautions.
