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 significant drop in the number of plastic bags littering Britain's seabeds suggests that a charge on plastic bags and other efforts to tackle marine litter are working, according to a new report.The study, published in the journal Science of the Total Environment, was carried out by scientists at the UK government's Centre for Environment, Fisheries and Aquaculture Science (Cefas), who analyzed data complied between 1992 and 2017 to reveal a drop of nearly 30% in plastic bags on Britain's seabeds.The report inspected 2,461 trawls off the UK's coasts and found that over the 25-year period, 63% of trawls contained at least one plastic litter item. 663

A team at the University of Kentucky is researching a possible treatment for COVID-19 and key helpers are three alpacas; Big Boy, Blue Eyes and Emperor.“It’s a powerful technology that we have at UK (University of Kentucky) and it’s something that hopefully we can develop some therapeutics with,” said Wally Whiteheart, a professor in the Department of Molecular & Cellular Biochemistry.Alpacas, along with llamas and camels, make a special kind of antibody called a nanobody. Nanobodies can be useful in cancer research and for other diseases. Researchers, led by Whiteheart and fellow professor Lou Hersh, are working with a nearby ranch to see what impact alpacas could have on COVID-19.“We, in a sense vaccinate them, and this case with viral proteins, and we make nanobodies to those viral proteins,” explained Whiteheart. “We can then go and purify and identify the nanobodies that bind to the virus and then test them to see if they can inhibit viral infection.”Making the nanobodies is just the first step. The team will see which, if any, can block virus infection and those candidates could move on to clinical trials.There’s still a lot of research and testing to go, and also still a lot of hope.“The cool thing which we’re exploring now is the fact that you might be able to use them as a nasal spray and this actually gets them to the place where the virus is affecting lung tissue,” said Whiteheart.This isn’t the first time the trio of alpacas has helped medical research. Big Boy, Blue Eyes and Emperor have contributed to the university’s nanobody research for more than three years. In that time, they have helped researchers generate more than 50 nanobodies to target proteins involved in a variety of human diseases including cancer, diabetes and neurological disorders.This story was originally reported by Alex Valverde on LEX18.com. 1869

A Tennessee man was arrested after watching ISIS videos, and then lying about his stay at a mental institution when he tried to buy a sniper rifle, according to federal officials.According to a federal indictment, federal agents began looking into Khari Malik Whitehead last year, after they talked to someone who knew him. That person told Metro Nashville Police they were concerned Whitehead was watching ISIS propaganda videos on the internet.They also told the ATF Whitehead may have possibly been radicalized, and that they were afraid that he may commit a mass murder one day.The indictment said Whitehead was committed to a mental institution late last year, but he lied about that in February on a background check form he filled out at the Walmart in La Vergne as he tried to buy a semi-automatic rifle. He asked to purchase a rifle that could "hold a lot of bullets"However, the purchase didn't go through. His stay at the mental institution was picked up by the background check, and Whitehead was denied the purchase.Whitehead's lie on the background check form was enough for federal prosecutors to file charges against him. 1175

A New Jersey state trooper admitted to the state's attorney general that he pulled over women while on duty in an attempt to ask women out on a date, WNBC-TV reported. The trooper, 37-year-old Marquice Prather, pleaded guilty on Monday to charges of invasion of privacy, tampering with physical evidence and falsifying or tampering with records. He had been suspended without pay since December after accusations mounted against the trooper. WNBC reported that Prather will be banned from public office, and likely will face probation for the charges. Authorities told WNBC that Prather tampered evidence by turning off his microphone, as the trooper claimed the microphone malfunctioned. Prather was accused by authorities of going through personal information and photos on the cellphones of female motorists. Prather was also accused of copying intimate photos and videos of the women, and he would solicit the women to go on a date with him. 1028
