(Between 1990 and 2015, that worldwide total declined from 41.3 million to 40.0 million square kilometers.) More than 98% of all land area in Suriname was forest in 2015, according to a related dataset — the highest proportion of any country. [h/t Tariq Khokhar + Max Galka]

The first featured Cézanne, Gauguin, Seurat, and van Gogh. [h/t Stacy-Marie Ishmael + Miriam Posner + Chad Weinard]

“Murray, I think you dropped New Zealand’s mineral exports for ‘08-‘09.” You don’t have to like Flight of the Conchords to enjoy New Zealand’s national statistics website, though it couldn’t hurt. The country publishes data on a broad range of topics, including abortion, work stoppages, the Māori census, and, of course, exports. In ‘08 and ‘09, the country exported NZD $3.5 billion and NZD $2.4 billion, respectively, of ”mineral fuels, mineral oils and products of their distillation; bituminous substances; mineral waxes.” [h/t Drew Ivan]
