It turns out that levels of water vapor in the atmosphere have dramatically increased over the last year-and-a-half, and water vapor is well recognized as a greenhouse gas, whose heightened presence leads to higher temperatures, a mechanism that dwarfs any effect CO2 may have.

So, why has atmospheric water vapor increased so dramatically? Because of a historic, gigantic volcanic eruption last year that I – probably along with you – had never heard of. The mass media ignored it because it took place 490 feet underwater in the South Pacific. Don’t take it from me, take it from NASA (and please do follow the link to see time lapse satellite imagery of the underwater eruption and subsequent plume of gasses and water injected into the atmosphere):
