Tunnel trees are a thing. Created in the 19th and early 20th century to promote parks and inspire tourism. They're good for engagement, but bad for the tree. One of the last known sequoia tunnel trees was recently brought down by a storm in California. A sequoia drive-throughable tunnel log does still exist.
Logic hacking - "Writing shorter and shorter computer programs for which it's unknowable whether these programs run forever, or stop... the winner of the Busy Beaver Game for N-state Turing machines becomes unknowable using ordinary math - somewhere between N = 5 and N = 1919." [more inside]
Thirty Million (direct Vimeo link), a U.N.-funded half-hour film about the expected effects of climate change on the country of Bangladesh.

Joshua - a time-lapse tribute to the beauty of Joshua trees, native to southwestern U.S. Photographer Sungjin Ahn embarked on his project after learning that climate change could "eliminate Joshua trees from 90 percent of their current range in 60 to 90 years." via PetaPixel
The dangers of living in a zero-sum world economy - naked capitalism reprints (with added commentary) an FT article by Martin Wolf on why it's vital for (civilised) society to sustain a 'positive-sum' world, otherwise: "A zero-sum economy leads, inevitably, to repression at home and plunder abroad." Wolf's solution? "The condition for success is successful investment in human ingenuity." Of course! Some are calling for more socialism, while others would press on to build more megaprojects. For me, at least part of the solution lies in environmental accounting and natural capitalism :P
A NOAA report says Earth's surface and atmosphere are both warming, and that earlier work that found otherwise contains flaws. In other news, global warming has started to weaken an important wind circulation pattern over the Pacific Ocean, a study suggests. The change could alter climate and the marine food chain in that area; polar bears and walrus pups sad.
Shocking photos which show just how much glaciers have melted in the last century. Now that the North Pole is a swimming pool, the Ross Ice Shelf has, as the Onion put it, embarked on a world tour, and the worst flooding in 800 years is hitting Eastern Europe, aren't we maybe a little bit worried about climate change... just a little, maybe? What freak weather phenomenon is creeping you out these days?
