SEATTLE (AP) — U.S. scientists said Friday they will investigate why an unusual number of gray whales are washing up dead on West Coast beaches.About 70 whales have been found dead so far this year on the coasts of California, Oregon, Washington and Alaska, the most since 2000. About five more have been discovered on British Columbia beaches. That's a very small fraction of the total number of whales believed to have died, because most simply sink and others wash up in such remote areas they're not recorded.NOAA Fisheries on Friday declared the die-off an "unusual mortality event," providing additional resources to respond to the deaths and triggering the investigation."Many of the whales have been skinny and malnourished, and that suggests they may not have gotten enough to eat during their last feeding season in the Arctic," agency spokesman Michael Milstein told reporters during a conference call.The eastern North Pacific gray whales were removed from the endangered species list in 1994, after recovering from the whaling era.The population has grown significantly in the last decade and is now estimated at 27,000 — the highest since surveys began in 1967. That has raised questions about whether their population has reached the limit of what the environment can sustain. Another theory suggests that the loss of Arctic sea ice due to global warming is a culprit.The whales spend their summers feeding in the Arctic before migrating 10,000 miles (16,000 km) to winter off Mexico. Though they eat all along their route, they are typically thinning by the time they return north along the West Coast each spring.They eat many things, but especially amphipods, tiny shrimp-like creatures that live in sediment on the ocean floor in the Arctic. For many years, researchers noted that fewer calves tended to be born following years when the ice in the Chukchi Sea, north of the Bering Strait between Alaska and Russia, was late to melt. The whales had less time to feast because they couldn't access the feeding area, and thus had less blubber to sustain them on their next migration.Last year, though, the Artic was unusually warm. The whales weren't blocked from the feeding area, and yet are still struggling this year. That has scientists wondering if the loss of sea ice has led to a loss of algae that feed the amphipods. Surveys show the amphipod beds moving farther north, said Sue Moore, a biological oceanographer at the University of Washington."The sea ice has been changing very quickly over the last decade or so," she said. "The whales may have to shift to other prey, such as krill or other things they eat."In an average year, about 35 whales wash up in the U.S.In 2000, more than 100 did, prompting NOAA to declare an "unusual mortality event" then as well. The resulting investigation failed to identify a cause. The die-off followed strong changes in ocean conditions in the mid-1990s, suggesting that warmer water patterns affected the availability of prey, but scientists were often unable to perform necropsies, Moore said."It's sometimes very difficult to get to these whales in a timely fashion," she said. "You can't always get the kind of samples you would need for diagnostic reasons."Since then, researchers have built up an improved network of volunteers and have better educated the public to help report and respond to whale deaths, said Deborah Fauquier, veterinary medical officer at NOAA's Office of Protected Resources. This time around, scientists have been able to perform necropsies on 20 of the whales, she said.John Calambokidis, a research biologist with the Cascadia Research Collective, noted that as the whales search farther afield for food, they've entered areas where they're not normally seen so often, including San Francisco Bay and Puget Sound. That puts them at higher risk of being struck by ships or entangled in fishing gear.Four of the 10 gray whales found dead near San Francisco this year were struck by ships, and a number of shipping companies have slowed their vessels in the area to avoid collisions. 4086

SEATTLE, Wash. -- Starbucks is the latest company to say it will pause social media ads after a campaign led by civil rights organizations called for an ad boycott of Facebook, saying it doesn’t do enough to stop racist and violent content.Starbucks says its actions were not part of the “#StopHateforProfit” campaign, but that it is pausing its social ads while talking with civil rights organizations and its media partners about how to stop hate speech online.“We believe in bringing communities together, both in person and online, and we stand against hate speech,” the company said in a statement Sunday. “We believe more must be done to create welcoming and inclusive online communities, and we believe both business leaders and policy makers need to come together to affect real change.”The coffee chain joined a growing group of companies saying they'll pause ads on Facebook or social media more broadly, including Unilever, the European consumer-goods giant; Coca-Cola; Verizon and dozens of smaller companies. 1029

SAN FRANCISCO (AP) — Wildlife officials say at least three new wolf pups have joined the only known pack in California.KQED reports that trail cameras set up by the state Department of Fish and Wildlife in northeast California recorded the pups and two or three adult wolves in June.Amaroq Weiss advocates for West Coast wolves with the Center for Biological Diversity. He says that the return of wolves to the state is an important development for conservation efforts.Wolves are protected under California's Endangered Species Act even as the federal Fish and Wildlife Service has proposed to delist grey wolves as an endangered species.In 2011, a grey wolf with a radio collar named OR-7 crossed the California border from Oregon and became the first wolf in the state since 1924. 791

SAN YSIDRO, Calif. (KGTV) - Business leaders on the U.S. side of the border are worried that President Trump's threat of tariffs against Mexico over illegal immigration could cause a sharp decline in sales.In the week after the president announced his plan to impose a 5 percent tariff on Mexican goods, the peso dropped nearly 4 percent in value. That means it's worth less compared to the U.S. dollar.Local shop owner Sunil Gakhreja, who is also a member of the San Ysidro Chamber of Commerce Board of Directors, said 99 percent of his customers come from Mexico. He also said if the peso gets much lower, people will stop crossing the border to shop.RELATED: Trump imposes tariffs on Mexico over border squabble"Right now, it's around 18 or 19 (pesos per dollar). That's fine," Gakhreja said. "But when it gets to 20, people won't come. Trust me, it's a ghost town; Nno one comes in."Trump's plan would impose a 5 percent tax starting June 10. The tariff would increase by another 5 percent every month through October, topping out at 25 percent. Trump said it will stay in place until Mexico can stop the flow of people crossing into the U.S. illegally.Gakhreja said he and other business owners are still feeling the effects of a five-hour border closure in November. That cost an estimated .3 million to local shops.Currency exchange businesses say they're keeping an eye on the changes from minute to minute.RELATED: Trump says Mexico tariffs likely to go into effect"It's horrifying," said Bertha Fridman with JSD Money Exchange. "It's the money that goes in your pocket, and that's less."Fridman said her business deals mostly with people exchanging dollars for pesos, and she won't be affected. But she hears from people south of the border, and they're worried."It's the psychology of the people," she said.RELATED: Tariffs on Mexico imports could have outsized impact on San Diego"Once their buying power drops, they will not buy from us," said Gakhreja. "Even if it changes by 2 or 3 pesos, that's real money. They'll walk." 2047

SAN FRANCISCO (AP) — Republican John Cox focused on his stance to try and fix the high cost of living in California, while Democrat Gavin Newsom highlighted his opposition to Trump during a debate Monday. The hour-long public radio debate remained civil, with the two candidates for governor sparring on policy and mostly avoiding personal attacks.Cox pledged to reduce taxes and regulations that he says drive up the cost of living in the nation's most populous state while Newsom, a former mayor of San Francisco, is running on his willingness to make bold decisions and his opposition to Trump.RELATED: San Diego County key dates to know before Election DayNeither strayed from their well-worn positions, and the debate appeared to do little to change the race in which Newsom is heavily favored."We represent the vast majority of Californians that reject John Cox's absolute allegiance to Trump and Trumpism," Newsom, California's lieutenant governor, said during what's likely to be the only one-on-one contest between the two men.Both candidates agreed that tackling issues such as housing affordability, homelessness and California's cost of living should be the priority of the next governor, but they presented vastly different visions for how to proceed.The two also sparred on criminal justice reform, immigration and the environment.RELATED: California sets record as voter registration tops 19 million"This campaign is about change versus the status quo. I represent change," Cox said in arguing that the policies of Democrats have made California unaffordable.The Nov. 6 election comes as the state faces a housing crisis and is drastically behind on building what it needs to house its population of nearly 40 million people.Cox said he would change environmental regulations that can make it so expensive to build in the state. Newsom hinted at reforming California's property tax system, saying rules that limit how much property tax cities can collect saps the incentive from building.On criminal justice reform, Newsom said he would continue the policies of outgoing Gov. Jerry Brown that focus on rehabilitating convicted criminals and putting fewer people behind bars.Cox said he wouldn't have signed a new law that opens police misconduct records to the public.Cox defended his support for a border wall and said California should undo its recently passed sanctuary law that limits local law enforcement cooperation with immigration authorities. Newsom strongly defended state immigration laws."I fear that under a Cox administration working hand-in-glove with Donald Trump that our progressive and enlightened polices on immigration will roll back into the dark ages," he said.The candidates split on a new California law that eliminates money bail. Cox said the policy wrongly eliminates the entire bail industry, while Newsom said systems based on money harm the poor and racial minorities.A September poll by the Public Policy Institute of California showed Newsom with a comfortable but shrinking lead over Cox — 51 percent to 39 percent with 7 percent of likely voters undecided.The survey had a margin of error of 4 percentage points.Newsom led 55-31 in the institute's July poll.Campaign finance records show Newsom had million in the bank on Sept. 22, compared with .7 million for Cox.Cox is a lawyer, accountant and investor from the San Diego area who has never held elected office. 3459
