>>This type of "hubris" is exactly what may doom Humanity. <<


doesn't the hubris resides among those who think we're powerful enough to change the weather?

If you want to worry yourself, pick something credible:

The world's population will double in 45 years, coincidental with the depletion of petroleum. A modern combine can harvest 900 bu of corn in an hour, but it used to take 9 hours to pick 100 bu by hand. Unless an adequate alternative to petroleum can be found, the planet's carrying capacity will fall precipitously. A new Dark Ages will follow.
