"the warming trend which resulted in the melting seen by Rasmussen's expedition actually started as early as 1840, before the industrial revolution and human-driven carbon emission had even got rolling. In that scenario, variations in the Sun seem to have much more weight than is generally accepted by today's climatologists."

Except that the Industrial Revolution started a hundred years before 1840, and was practically over by then.

But apart from just moving time to fit the facts, they could have a great point. :o/
