I am compelled to disagree that there is a consensus of scientists who agree that this [climate change] is the consequence of human activities. While the melting of permafrost, retreat of glaciers and waning of the permanent ice pack may be alarming, it is only alarming to those unfamiliar with past changes in climate in the North. Paleoclimatologists recognize such events as part of natural changes wholly unrelated to CO2 concentrations in the atmosphere. In fact, the waxing and waning of ice shelves, along with glaciers, ice caps and pack ice are largely related to changes in solar inputs.
