2016 Was the Hottest Year Ever Recorded

Man, it’s a hot one. And by “it” we mean 2016. Reports issued this week by NASA [PDF], NOAA, and the UK Met Office have all concluded that 2016 was the hottest year on record, beating out the sweltering temperatures of the prior two years—which were also record breakers. 

Experts have been taking our planet’s temperature every day since the late 1880s. Longer-term models and projections suggest that the last time Earth got this hot was about 115,000 years ago [PDF].

Last year saw an eight-month stretch of record-high global temperatures from January to August, and all low temperatures met or exceeded the 20th-century average. Sea ice shrank and water levels rose.

Climate scientists like Michael Mann of Penn State University say there can be no doubt about the cause. “The effect of human activity on our climate is no longer subtle,” he told The Guardian. “It’s plain as day, as are the impacts—in the form of record floods, droughts, superstorms, and wildfires—that it is having on us and our planet."

Participants in 2015's Paris accord agreed on the importance of limiting further climate change, and set a maximum cap of a 1.5°C increase in average temperature. We’re currently at 1.1°C.

The time to act is now, says NOAA’s Kevin Trenberth, who says that those who oppose environmental protections for financial reasons would be wise to reconsider. “While there may be some cost in mitigating climate change,” he told The Guardian, “there are already major costs in damages.”

Appealing directly to lawmakers’ wallets, Trenberth argues that “sensible approaches” to cutting emissions and boosting climate resilience “can actually make it a net gain, not only for the planet [but] for everyone.”

A Pile of Manure and a Heat Wave Combined to Cause Spain’s Worst Wildfire in 20 Years

A pile of manure in Spain ignited on June 27, sparking a wildfire that has torn through more than 10,000 acres of forest and other Catalonian landscapes, CNN reports. The manure combusted in part because of a scorching heat wave that has swept across Europe this week; temperatures in the affected region hit 104°F, and Germany, Poland, and the Czech Republic all reached record-breaking June temps. Catalan regional interior minister Miquel Buch reported that authorities believe the manure was improperly stored on a chicken farm in the village of La Torre de l’Espanyol, where it was exposed to the worst of the heat, according to NBC News. The wildfire—Spain’s most devastating in 20 years—is affecting the region just west of Tarragona, a port city that is best known for its Roman ruins, which is situated along the Balearic Sea about 60 miles southwest of Barcelona.

Though high temperatures are expected to continue and the rough terrain itself is also a contributing factor in the rapid spread of the fire, the strong winds should soon abate; authorities have warned people to stay inside. Though more than 50 people have been evacuated from the area, no deaths have been reported thus far. While the spontaneous combustion of flammable materials like manure, hay, or compost is definitely possible, as evidenced by this situation, it’s not the most common way for wildfires to start. More common causes include lit cigarettes, unattended campfires, burning debris, and engine sparks. [h/t CNN]

Colorado Welcomed Summer With 2 Feet of Snow

While people in some parts of the country celebrated the first day of summer with barbecues and trips to the beach, residents of north and north-central Colorado had a snow day. Areas west of Denver—including Grand Lake, Aspen, and Steamboat Springs—experienced snow storms on summer solstice, with snowfall totaling nearly 2 feet at the highest elevations, CBS Denver reports.

Snow started falling in the Rocky Mountains the morning of Friday, June 21 and continued Sunday. Areas at ground level weren't cold enough to experience the unusual weather, but at elevations of 7000 feet and above, it looked like a winter wonderland. Steamboat Springs, a ski resort town in Colorado’s Yampa Valley, accumulated 20 inches of snow on the longest day of the year.

While Colorado mountain towns are used to seeing snow at odd times of year, the weekend's weather was still out of the ordinary. The average snowfall for Steamboat Springs in June is 0.1 inches. Prior to last Friday, it had been 91 years since a snowstorm hit the city in late June.

Snow has fallen in the Rockies later than average in six out of the past seven years. Though it feels like an extension of winter, the trend may actually be a product of the warming atmosphere. A warmer climate affects the jet stream, potentially pushing its course further south and leading to unusual weather patterns, such as unseasonable snowstorms in Colorado.

That means residents of some parts of the state will have to wait to have their summer hikes and picnics. The weather was serious enough to shut down one road in Rocky Mountain National Park.
