Another amazing visual

This view of the population of the world by Alasdair Rae (@undertheraedar) is a view I really didn't know well. The US has 300 million people- about the same as Indonesia, but spread out over a much larger area. I had no idea about how dense East Africa was, or even Central America/ Colombia. This is a good reminder that half of of the world population lives in a relatively small part of the world, namely from west of India though China and out to Japan in the northeast and through Indonesia in the south. 

Wind vs. Coal

This fun tongue-in-cheek article highlights the many "contributions" of coal. While the point is well made (and appreciated) I wonder if the experts are laughing- we need to worry not only about total capacity but also about peak hours, plant footprints, etc. Not sure we can just wave our hands and hope offshore wind solves everything!

Farmland values

 An interesting visual from @ArielOrtizBobea. What factors can you think of that contributed to this? There are so many! One commenter points to the market for second homes within driving distance of urban areas. Another points to the developing market for oranges in southern California. My question is about rising subsidies over time that fueled the growth in land values in Iowa and other places in the Midwest. So many factors: a great visual!
