| I don't understand your complaint. Consider this fact: > There is less snow in the lowlands. In parts of the Oslo wildlands, the skiing season has become nearly 40 days shorter. So we have an observable, measurable, falsifiable fact. It correlates or trends with global mean temperature changes. We have a mechanism of action. We have an arrow of causality, based on established scientific observations and experiments going back decades. I'm not sure what else you want. You mention lack of citations, but they do have citations. For example, the browning water section clearly links to this paper [1]. That paper looks at data going back three decades and emphasizes (in the title, no less) the very arrow of causality you want. "Correlation is not causation" is a weird, toothless complaint here. They're not plotting fedoras on the x-axis and global mean temperature on the y-axis. I'm worried that this kind of Hacker News comment only helps climate-change deniers.

EDIT: I see now. The "source" button they've used for citations doesn't work correctly for me in Safari and Chrome (it scrolls way up, and only if you scroll back down will it start showing the footnotes). It's also only in Norwegian.
