The UN climate treaty summit known as COP29 teetered on the edge of collapse as less developed nations implored the rich countries of the global north to provide financial relief to help them cope with rising climate costs. Alden Meyer of E3G was at the COP and explains the frustrations with the process and the compromise delegates eventually reached. 
Also, astronomer Phil Plait wondered what it would be like to walk on Mars, fall into a black hole, or fly through a nebula, so he wrote a book, Under Alien Skies: A Sightseer’s Guide to the Universe. He reveals the strange colors of a sunset on Mars, what it’s like on a planet orbiting binary stars, the unique challenges of landing on an asteroid, and more.
