I spent the weekend reading a book I wasn’t entirely comfortable being seen with in public. Andreas Malm’s “How to Blow Up a Pipeline” is only slightly inaptly named. You won’t find, anywhere inside, instructions on sabotaging energy infrastructure. A truer title would be “Why to Blow Up a Pipeline.” On this, Malm’s case is straightforward: Because nothing else has worked.

Decades of climate activism have gotten millions of people into the streets but they haven’t turned the tide on emissions, or even investments. Citing a 2019 study in the journal Nature, Malm observes that, measuring by capacity, 49 percent of the fossil-fuel-burning energy infrastructure now in operation was installed after 2004. Add in the expected emissions from projects in some stage of the planning process and we are most of the way toward warming the world by 2 degrees Celsius — a prospect scientists consider terrifying and most world governments have repeatedly pledged to avoid. Some hoped that the pandemic would alter the world’s course, but it hasn’t. Oil consumption is hurtling back to precrisis levels, and demand for coal, the dirtiest of the fuels, is rising.
