&gt; If you agree because someone says so, that&#x27;s just another form of ignorance.<p>No it isn&#x27;t, it&#x27;s not possible to educate yourself to the depth required on a great many things without becoming a professional in the field and while that&#x27;s cool for those that want to; it&#x27;s utter arrogance and ignorance to ignore the entire scientific community as a laymen and pretend you know better.  Quite simply, if you are not a climate scientist, you&#x27;re talking out of your ass.  The people educated enough in the evidence to have the rational debate, have already had it, the intelligent debate is over and the conclusions have been publicized.  The only people still debating are the few scientists in the extreme minority (which is fine), and the utterly ignorant (i.e. the public).
