Unless you're on a university server, you'll probably find that the article is gated. [Update - The working paper version is accessible here.] Fortunately, there are a number of good summaries available on the net. Bottom line: We severely underpay for the goods and services provided by major industries, given the measurable effect that air pollution from these industries has on human health and productivity.
Crucially, the environmental damages that drive these results have nothing to do with any kind of long-term climate change effects. They are simply the local damages that result from compromised air quality and are happening right now.
Lest it be unclear, this most certainly isn't about turning our back on coal (or even agriculture, another industry with a surprisingly high un-costed air pollution damages figure). Or markets in general. It is simply about trying to account for full costs and thinking about the best ways in which we can do that. That's all that good economics is about.
