2021 obeyed physics, was one of the warmest years on record

We are still in the midst of running a dangerous experiment on Earth’s climate system, and we get to periodically check in on the results—like laboratory rats peering at the graphs on a whiteboard across the room. And it’s that time again.

Every year, global temperature can be compared to the predictions born of the physics of greenhouse gases. A number of groups around the world maintain global surface temperature datasets. Because of their slightly differing methods for calculating the global average and slightly differing sets of temperature measurements fed into that calculation, these datasets don’t always arrive at exactly the same answer. Lean in close enough and you’ll see differences in the data points, which can translate into differences in their respective rankings of the warmest years. The big picture, on the other hand, looks exactly the same across them.

NASA, NOAA, and the Berkeley Earth group each released their end-of-year data for 2021 today, while the Japanese Meteorological Agency (JMA) and European Centre for Medium-Range Weather Forecasts (ECMWF) numbers were already out. They all came up with similar rankings this year. All but ECMWF placed it as the sixth warmest year on record, while ECMWF ranked it in fifth place. It was very close to 2015 and 2018, so fifth through seventh are roughly tied. What is true for all of the datasets is that the last seven years are the warmest seven years on record.

Ancient Peruvians partied hard, spiked their beer with hallucinogens to win friends

Lacing the beer served at their feasts with hallucinogens may have helped an ancient Peruvian people known as the Wari forge political alliances and expand their empire, according to a new paper published in the journal Antiquity. Recent excavations at a remote Wari outpost called Quilcapampa unearthed seeds from the vilca tree that can be used to produce a potent hallucinogenic drug. The authors think the Wari held one big final blowout before the site was abandoned.

“This is, to my knowledge, the first finding of vilca at a Wari site where we can get a glimpse of its use,” co-author Matthew Biwer, an archaeobotanist at Dickinson College, told Gizmodo. “Vilca seeds or residue has been found in burial tombs before, but we could only assume how it was used. These findings point to a more nuanced understanding of Wari feasting and politics and how vilca was implicated in these practices.”

The Wari empire lasted from around 500 CE to 1100 CE in the central highlands of Peru. There is some debate among scholars as to whether the network of roadways linking various provincial cities constituted a bona fide empire as opposed to a loose economic network. But the Wari’s construction of complex, distinctive architecture and the 2013 discovery of an imperial royal tomb lend credence to the Wari’s empire status. The culture began to decline around 800 CE, largely due to drought. Many central buildings were blocked up, suggesting people thought they might return if the rains did, and there is archaeological evidence of possible warfare and raiding in the empire’s final days as the local infrastructure collapsed and supply chains failed.

One of Nintendo Switch’s best puzzle games is now (mostly) free for 7 days

Nintendo mixes cool, weird, and ho-hum perks into its $20/year Switch Online subscription service, including one we don’t generally talk about: limited-time game trials. Other modern gaming services include this sort of thing, particularly “Days With Gold” on Xbox Live, and the idea is that subscribers can temporarily test unlocked retail versions of games for no additional cost.

Generally, these deals range from intriguing to annoying, though they’re at their worst when they feel like glorified advertisements for online games: Try a game for as little as 72 hours, get hooked, then buy it when the promotional timer runs out and locks the game. This week, however, a new deal exclusively for Nintendo Switch Online subscribers gets my wholehearted recommendation.

Starting right now—as of 1 pm EST today, January 13—the 2019 Switch puzzle game Captain Toad: Treasure Tracker is fully unlocked for anyone already paying for the $20/year NSO service. Its free trial lasts for a little over seven days, expiring at 2:59 am EST on Friday, January 21.

Elizabeth Holmes’ trial was delayed for months, and now her sentencing will be similarly held up. The judge in her trial scheduled the hearing for late September.

US District Judge Edward Davila’s order, issued yesterday, set sentencing for September 26. He also set aside June 16 to address motions that Holmes’ attorneys are likely to file in which they may ask for the conviction to be reversed or for a new trial.

Holmes was convicted earlier this month of three counts of wire fraud and one count of conspiracy to commit wire fraud. The jury was hung on three counts, which prosecutors moved to dismiss in a filing made jointly with Holmes’ attorneys. The former CEO of Theranos was acquitted of the remaining charges of wire fraud against patients.
