The previous year, the two rivers had been comparable in size, but the Alsek was now 60 to 70 times larger than the Slims, flow measurements revealed. The data also showed how abrupt the change had been, with the Slims flow dropping precipitously from the 26 to 29 May 2016. Geologists have previously found evidence of river piracy having taken place in the distant past. But nobody to our knowledge has documented it happening in our lifetimes, said Shugar. People had looked at the geological record, thousands or millions of years ago, not the 21st century, where its happening under our noses. Prof Lonnie Thompson, a paleoclimatologist at Ohio State University who was not involved in the work, said the observations highlight how incremental temperature increases can produce sudden and drastic environmental impacts. There are definitely thresholds which, once passed in nature, everything abruptly changes, he said. Glacier melt shows a climate change tipping point. In 2016, there was a sudden acceleration of the retreat, and the pulse of meltwater led to a new channel being carved through a large ice field. The new channel was able to deliver water to the Alseks tributary whose steeper gradient resulted in the Slims headwater being suddenly rerouted along a new southwards trajectory. In a geological instant, the local landscape was redrawn.

It was something internal. … I just laid down and said, ‘I’m done for the week.'” Minutes later in the interview, he said, “The moment I laid down at the back of [that gym], I instantly knew it was because of that medical marijuana.” http://christianrichardsonplus.accessnetwork.us/2017/04/19/a-useful-a-to-z-on-products-for-course-for-interview/Champions MMA @ChampionsFight “I was actually high on marijuana, in that sativa mindset, during that training session.” – Diego Sanchez #TheMMAHour 4/17/2017, 7:45:34 PM Sanchez, who said he obtained a medical marijuana license after a fight in November and had been smoking the drug experimentally for the past several months, did not initially seek medical treatment for the discomfort, but hypothesized that his heart was palpitating or not receiving enough oxygen. “Whatever happened, it was serious,” Sanchez said. “I could feel something going on, and I was very, very terrified that if I got my heart rate back up that I could, like, die or something.” Sanchez said he still felt “uncomfortable” the following morning and for days after. Instead of going to a hospital or doctor, however, he chose to fast and pray for several days, taking time off from training. He told many at the time that he had the flu, but internally he remembers thinking, “What if my career’s about to be over?” After that, Sanchez did visit the hospital, at which point he said the doctors told him he had “a perfectly fine, healthy heart,” and that what he was feeling was “a muscular injury.” “I received a miracle that day,” Sanchez said. But Sanchez didn’t believe it was a muscular injury. Jeff Bottari/Zuffa LLC/Getty Images “My lungs were being affected,” he said. “And I still had the mentality to train like a warrior, so when [the heart issue] happened to me, that day at the gym, I was still experimenting with medical marijuana. … I did it, and I loved it, and I got my medicinal medicine.
