"KT Tunstall said growing up in Scotland and seeing the effect of climate change to the coastline there spurred her into action."
She is such a keen observer - and such scientific insight for an "artist". Art, science - its all the same, right?
She's probably as qualified as Dennis Avery, who is one of the authors of the first of the two books mentioned in the Drudge blurb. Avery is an economist, not a scientist, which makes him no more qualified than an English teacher, Mary Kay salesperson, or Al Gore to give a scientific opinion on global warming.
