According to who? People like you who never gave it any credence in the first place?
Wrong, P. I did buy into the temperature rise...it felt that way out in my garden. And I bought the polar ice thing too. And strange enough back in the Global Winter days (early 70's I think), I believed that too...though my rational processes were altered by various perceptive chemical-based mechanisms.
One thing is the same, and that is the mindset of the folk who were and are behind such. It's people who think EVERYBODY should hold the same values that they do, and they attempt to promote and implement their values through manipulating State mechanisms. For the common good...of course.
Like I've hinted to some of my Green friends...if this economy tanks big time (like it will if current policy is continued)...it won't be the sun that heats this place up. It'll be your starving and desperate fellow humans. And it won't take 50 years...more like 50 days.
