It's not surprising that a quickly acknowledged and corrected discrepancy in temperature recording by NASA was pounced on by the denier camp to further the proof that global warming is a hoax! Unsurprisingly, the reports have been biased and have omitted certain key facts, not the least of which is that the GLOBAL temperature record (it is after all, global warming) remains largely unaffected by the corrected data.
New Republic has published an excellent review of the facts using - wait for it - scientific data!
Democracy is utterly dependent upon an electorate that is accurately informed. In promoting climate change denial (and often denying their responsibility for doing so) industry has done more than endanger the environment. It has undermined democracy.
There is a vast difference between putting forth a point of view, honestly held, and intentionally sowing the seeds of confusion. Free speech does not include the right to deceive. Deception is not a point of view. And the right to disagree does not include a right to intentionally subvert the public awareness.
