Most frightening stories:

• The idea of a soft landing where absolute dematerialization of the economy reduces our ecological footprint and sidesteps the consequences of climate change through innovation without serious pain may be wishful thinking.
• Lake Powell is in increasingly deep (actually shallow, ha ha) trouble.
• The American Academy of Pediatrics says climate change is already killing children.

Most hopeful stories:

• There are some new ideas for detecting the potential for rapid ecological change or collapse of ecosystems.
• Psychedelics might produce similar benefits to meditation.
• Microgrids, renewables combined with the latest generation of batteries, are being tested in Puerto Rico.

Most interesting stories, that were not particularly frightening or hopeful, or perhaps were a mixture of both:

• I learned about the stag hunt, a cousin of the prisoner’s dilemma in game theory.
• Uber Air is looking a little more real. There are other ideas for autonomous urban helicopters too.
• Connecticut is the latest U.S. state to join the National Popular Vote Compact.
