A new US government report delivers a dire warning about climate change and its devastating impacts, saying the economy could lose hundreds of billions of dollars by the end of the century.The federally mandated study was supposed to come out in December but was released by the Trump administration on Friday, at a time when many Americans are on a long holiday weekend, distracted by family and shopping.David Easterling, director of the Technical Support Unit at the NOAA National Centers for Environmental Information, emphasized that there was "no external interference in the report's development." He added that the climate change the Earth is experiencing is unlike any other."The global average temperature is much higher and is rising more rapidly than anything modern civilization has experienced, and this warming trend can only be explained by human activities," Easterling said.Coming from the US Global Change Research Program, a team of 13 federal agencies, the Fourth National Climate Assessment was put together with the help of 1,000 people, including 300 leading scientists, roughly half from outside the government.It's the second of two volumes. The first, released in November 2017, concluded that there is "no convincing alternative explanation" for the changing climate other than "human activities, especially emissions of greenhouse gases."The report's findings run counter to President Donald Trump's consistent message that climate change is a hoax. On Wednesday, Trump tweeted, "Whatever happened to Global Warming?" as some Americans faced the coldest Thanksgiving in over a century.But the science explained in these and other federal government reports is clear: Climate change is not disproved by the extreme weather of one day or a week; it's demonstrated by long-term trends. Humans are living with the warmest temperatures in modern history. Even if the best-case scenario were to happen and greenhouse gas emissions were to drop to nothing, the world is on track to warm 1.1 degrees Fahrenheit.As of now, not a single G20 country is meeting climate targets, research shows.Without significant reductions in greenhouse emissions, the annual average global temperature could increase 9 degrees Fahrenheit (5 Celsius) or more by the end of this century, compared with preindustrial temperatures, the report says. 2355

A new lawsuit says a woman who tried on lipstick at a Sephora cosmetics store in Hollywood, California got herpes from the sample.The unidentified woman claims it happened at the store in October 2015, according to a report by TMZ. She ended up with herpes on her lip and says she never had it before the visit to the store.The documents say the store failed to clearly warn the woman of the risk of getting a disease from using samples of lipstick there.The lawsuit says the woman is suing over the emotional distress for getting an "incurable lifelong affliction." Sephora did not respond to the TMZ article, but a spokesperson for the retailer did respond to Fashionista, saying the health and safety of its customers is a priority. It did not comment on the lawsuit. 793

A small town in Canada's Saskatchewan province mourned Saturday after a bus carrying a junior hockey team collided with a tractor-trailer, leaving 15 people dead and at least 14 injured."This is a dark moment for our city, our community, our province," Humboldt Mayor Rob Muench said Saturday afternoon at a news conference. "There is no playbook on what to do in cases like this."Members of the Humboldt Broncos hockey team were headed to the town of Nipawin for a playoff game Friday night when the crash happened north of Tisdale, the Royal Canadian Mounted Police said. 581

A Texas jail guard suffered a heart attack two years ago, and if not for a group of inmates, he could have lost his life, WFAA-TV reported.Gary Grimm of Weatherford, Texas is thankful for those inmates who gave the now 52-year-old retired jail guard a second-chance at life."Instead of overtaking me and taking my gun, and killing me or taking a hostage and escaping, they looked at me as a human being," Grimm told WFAA. The inmates reportedly had to knock down a locked gate to get to Grimm after they realized he was having a medical emergency. The group of eight inmates were able to get the attention of others in the jail, who were able to help Grimm seek medical attention. Grimm never got the opportunity to personally thank the inmates as they were transferred to other institutions."I get emotional. If they wished harm for me, all they had to do was sit there and do nothing," Grimm told WFAA. Grimm said he treated inmates the way he would want to be treated. Perhaps, that is why they came to his aid when he needed it."I don't care if they're a drug user, hot check writer, or child molester. They're still a human being. I don't have to like what they did, but it's not my position to be the judge and jury," Grimm told the station. 1275
