Steven may be a capable sci­en­tist in his respec­tive field but he has not shown the ability to objec­tively eval­uate the cli­mate change ques­tion. Many of his asser­tions sound alarmist in nature. Further, the inability to engage in debate sug­gests that he is at his core not advo­cating a sci­en­tific agenda. The warming ques­tion is con­tro­ver­sial for one reason — there is no con­sensus. Manning and Hansen just two name two are being actively ques­tioned on their methods and con­clu­sions. The chal­lenges are real and must be taken seri­ously. AS a sci­en­tist I am sure that Steven is aware of the chal­lenges that Newton and Einstein endured when they ques­tioned the received wisdom.
