Regarding the two TIME covers... 40 years ago scientists knew the that increasing CO2 would change the earth, the debate was whether heat would be screened out, making it colder, or heat would be blocked in, making it warmer. It took time, but the debate was resolved. It was like watching a tree being cut down. You know it is going to fall, with great impact, just not sure which direction.
That's not a labyrinth. That is a map of the Berlin subway system, which functioned quite well last time I rode it.
