preindustrial

Last year was Earth’s hottest on record with a global average surface temperature about 1.46 degrees Celsius above the preindustrial baseline — closer than ever to the 1.5 degree threshold.

There is a very good chance that average warming over the next five years will be more than 2.7 degrees Fahrenheit, or 1.5 degrees Celsius, above preindustrial levels, the cap established by the Paris Agreement to ward off the worst consequences of climate change.

The preindustrial cadence of rural life, a time before the invention of Dusen Dusen pepper grinders and frozen lasagna, is what the tradwives of Instagram are channeling, though they can muster only a shallow simulacrum of it.

“A single year with temperatures 1.5° C above preindustrial levels does not mean we’ve reached 1.5° C of global warming,” Rogelj said.

The global mean temperature also rose to nearly 1.5 degrees above the preindustrial level, another record.
