On the future of walls, or The Wall

Space may be the endless frontier, but here on Earth, we define space in the modern sense as something enclosed. Walls, fences and barriers enclose space, define it and make it legible.

When it comes to climate change, it might seem that a book entitled “How to Do Nothing” would not only be irrelevant, but also downright obscene and even dangerous.

Can the world really just fall apart?

Books on climate change, as diverse as the library is, tend to fall into a couple of categories.

Following the IPCC’s report, we need more technology to respond to more disasters

This week, the Intergovernmental Panel on Climate Change released its major sixth assessment report on the physical science of climate change. The details are grim, if getting more precise as better and more comprehensive data becomes available.
