SAN FRANCISCO (AP) — The Coast Guard is investigating what caused a ferry boat to crash twice into docks at San Francisco's famed Ferry Building, slightly injuring two people aboard.Coast Guard spokesman Chris Shih says investigators are looking into mechanical issues and other factors that led to Friday's crash. The agency regularly inspects the ferries.A Golden Gate Ferry spokeswoman says the boat was traveling from Larkspur and carrying 53 passengers when it struck an outer berth before bumping into another dock.The vessel's hull was damaged when it struck the concrete promenade and knocked a guardrail. The Coast Guard says there were reports of two minor injuries that didn't require treatment beyond first aid.Witness Tiffany Dennis says the crash set off panic among a crowd of people dining and shopping at the waterfront attraction. 856

Scientists are warning that a domino effect will kick in if global temperatures rise more than 2 degrees Celsius above pre-industrial levels, leading to "hothouse" conditions and higher sea levels, making some areas on Earth uninhabitable.The report, "Trajectories of the Earth System in the Anthropocene," published Monday in the American Proceedings of the National Academy of Sciences, said "hothouse" temperatures could stabilize 4 degrees to 5 degrees Celsius (39 to 41 Fahrenheit) higher than pre-industrial levels."Human emissions of greenhouse gas are not the sole determinant of temperature on Earth. Our study suggests that human-induced global warming of 2 degrees Celsius may trigger other Earth system processes, often called 'feedbacks,' that can drive further warming -- even if we stop emitting greenhouse gases," lead author Will Steffen of the Australian National University said. 911

SEATTLE — Add marine wildlife to the growing list of life affected by America’s opioid crisis.For the first time, scientists have detected traces of oxycodone in mussels near Seattle, KIRO7 reported. Biologist Jennifer Lanksbury explained whatever people eat and excrete — including opioids — end up in waterways.“It’s telling me there's a lot of people taking oxycodone in the Puget Sound area,” Lanksbury said. Washington Department of Fish and Wildlife officials extracted mussels from clean water and put them in urban areas they wanted to test for contamination. There was enough oxycodone in a Seattle-area bay for the mussels to test positive.The system that filters water catches a lot of contaminants, but it can’t specifically filter out drugs, Kings County Wastewater Management said.“Those are definitely chemicals that are out there in the nearshore waters and they may be having an impact on the fish and shellfish that live there,” Lanksbury said.The data was from a one-time study for prescription drugs in Washington’s waterways, but officials say they will try to get more funding to continue research. 1163

Sen. Amy Klobuchar, D-Minn., said in an MSNBC interview late Thursday that she is no longer interested in being Joe Biden’s running mate in this fall’s presidential election.Klobuchar was considered among the favorites to be pegged as Biden’s running mate. On Thursday, she took her name out of the running.Klobuchar cited her desire to see a woman of color as part of the reason she is taking herself out of the running. Biden, who previously said he would likely choose a woman as his running mate, has received pressure to choose a minority to be his running mate in the weeks since the death of George Floyd.With Klobuchar’s past as a prosecutor, and given Floyd was killed by officers in Klobuchar’s home state, many pundits believed her viability as a running mate dropped.“After what I have seen in my state, what I have seen across the country, this is a historic moment,” Klobuchar said. “America must seize on this moment and I truly believe, as I told the vice president last night, I think this is a moment to put a woman of color on that ticket."According to an Associated Press report last week, Sen. Kamala Harris and former National Security Advisor Susan Rice were among those being vetted.Klobuchar joined Biden in a crowded Democratic field vying for the party’s presidential nomination. Klobuchar briefly gained momentum following a solid performance in New Hampshire, but following lackluster results in Nevada and South Carolina, Klobuchar exited the race and endorsed Biden the night before Super Tuesday. 1536

San Francisco may be the next U.S. city to allow 16- and 17-year-olds to vote. Residents will vote on the matter this November.If the measure is passed, the young people would be able to participate in local elections, which usually don't have high turnout.“They've seen that by extending voting rights to people of that age, they've actually increased the level of interest and attention in local politics, not only in those who are newly able to vote, but among their parents and their communities as well,” said Brandon Klugman, Vote 16 Campaign Manager at Generation Citizen.Critics question if teens are mature enough and educated enough to vote.Researchers in Austria, where the national voting age starts at 16, found teens are not likely to be less educated or less motivated to participate in voting.The campaign Vote 16 USA says teens are not likely to make rushed or stressed decisions when it comes to voting.They say teens are more likely to be in a stable environment, where they're surrounded by family, peers, and educators.“In a stable environment, it's great to establish the habit of voting, whereas at 18 on the other hand, most folks are in some sort of intense transition, whether that's joining the workforce, starting college, moving away from home, or going after some sort of transition,” said Klugman.Advocates say this will help in creating a life-long habit of voting.Oakland, California, is considering a similar measure, but it would only allow young voters to participate in school board elections.Several cities in Massachusetts and Maryland have passed similar measures. Something like this was also considered in Washington D.C. but did not pass. 1689
