Counting water vapor (which is frankly ridiculous) gets Pinatubo up to 491Mt. Mankind emits about 20,000 Mt of water vapor a year. Again, comparing water vapor is ridiculous

The following is from a source that supports, as you do, the BS of "man-made global warming". Seems they differ with you on the importance of water vapor in Earth's greenhouse system....

Water Vapor Confirmed As Major Player In Climate Change

ScienceDaily (Nov. 17, 2008) — Water vapor is known to be Earth's most abundant greenhouse gas, but the extent of its contribution to global warming has been debated. Using recent NASA satellite data, researchers have estimated more precisely than ever the heat-trapping effect of water in the air, validating the role of the gas as a critical component of climate change.

That’s going to leave a mark.

Water Vapor Confirmed As Major Player In Climate Change

Damn Dihyrdogen Monoxide....that stuff should be banned.

Again from the source that supports "man-made global warming"...

"Andrew Dessler and colleagues from Texas A&M University in College Station confirmed that the heat-amplifying effect of water vapor is potent enough to double the climate warming caused by increased levels of carbon dioxide in the atmosphere."
