...but what a load of hogwash. Today, we are one entire degree warmer than "pre-industrial temperatures", which they define as around 1850. Coincidental, I'm sure, that the "Little Ice Age" ended around 1850, meaning that they could hardly have picked a colder point in time. I should certainly hope that we are warmer than that! The Little Ice Age saw the largest glacier extents for thousands of years, devastating many communities as they were inexorably covered with ice.
Note, also, the temperature graph in that article - a lot more than one degree drop from temperatures a couple of centuries before, which brings us to the next point. They label today's temperature range as "uncharted territory", despite the fact that the planet was almost certainly warmer than this during the Medieval Warm Period, and before that during the Roman Climate Optimum.
The rest of the TFA is all about beating the panic-drum.
