SAN DIEGO (CNS) - Two researchers, including one from the Scripps Institution of Oceanography at UC San Diego, are in Antarctica in an effort to uncover the planet's oldest ice.The research trip is part of a cordial international race to find the ice, which will give geologists and climate scientists new insight into Earth's climate history. Scripps paleoclimatologist Jeff Severinghaus and University of Minnesota-Deluth geologist John Goodge arrived this month at an ice-drilling outpost at McMurdo Station, Antarctica.In October, Severinghaus and researchers at Princeton University published a study in the journal Nature analyzing a two-million-year-old ice core. However, that core was incomplete in its historical portrait of ancient air. According to Severinghaus' ice dating lab, the planet's oldest ice is roughly 2.7 million years old.RELATED: San Diego Zoo welcomes second rhino born via artificial inseminationSeaWorld frees whale tangled in 900 feet of rope off La JollaSan Diegans can fly over rush-hour traffic with FLOAT air service"That core ... was all broken up," Severinghaus said of the Princeton study. "It's like in archaeology when you find pieces of broken pottery you're trying to put back together."The two researchers are attempting to expedite the conventional ice drilling process, which currently takes roughly five years to dig two miles to the Antarctic ice shelf's deepest point. They believe their 50-ton drill could secure a 50-meter ice core with a full timeline of the continent's geologic development. Eventually, it could be used to dig to the continent's bedrock, which dates back 3 billion years.In addition to each other, geologists and climate scientists in the southern hemisphere are in a race against nature, as climate change continues to melt Antarctic ice and cause sea levels to rise, particularly on the continent's western edge, according to Goodge."The bigger question is what's happening in East Antarctica because there's a lot more sea level rise potential if it begins to melt as well," he said. "So we really need to understand what those conditions are."Once collected, the researchers will pack the ice samples in boxes until January, when the Antarctic sea ice thaws and the samples can be shipped to Port Hueneme in Ventura County. They will then be transported to the National Science Foundation's Ice Core Facility in Lakewood, Colorado, for study in late spring. 2439

SAN DIEGO (KGTV) — A driver heading the wrong-way on Interstate 805 died following a fiery crash with another vehicle Saturday.A Mitsubishi Lancer traveling the wrong-way on southbound I-805 near the I-8 connector collided with a Toyota SUV just before 3 a.m., according to California Highway Patrol. The collision sparked a fire, engulfing both vehicles, CHP said.Both drivers were transported to a nearby hospital with life-threatening injuries, according to California Highway Patrol. The wrong-way driver later died. Another vehicle received minor damages in the wreck. That driver received minor injuries.CHP was still investigating where the wrong-way driver entered the freeway. It's not clear if alcohol or drugs was a factor in the crash.A portion of I-805 was closed as crews cleared the scene, but was reopened before 7 a.m. Saturday. 855

SAN DIEGO (CNS) - The state Supreme Court Thursday ruled that a San Diego citizens' initiative that cut back city employee pensions was illegally placed on the ballot, and ordered an appeal court to consider a remedy.Proposition B, initially approved by voters in 2012, eliminated guaranteed pensions for new city employees, except police officers, and replaced those benefits with 401(k)-style retirement plans.In 2015, one of the city's largest public sector unions challenged the benefit system, alleging former Mayor Jerry Sanders and other officials illegally placed the measure on the ballot without conferring with labor groups. The Public Employees Relations Board ruled with the union, but the Fourth District Court of Appeal reversed the decision in April 2017.Now, the appeal court's decision is overturned."We reverse the Court of Appeal's judgment and remand for further proceedings to resolve issues beyond the scope of this opinion," wrote Associate Justice Carol A. Corrigan in Thursday's decision, in agreement with the other five justices.A city spokesperson couldn't be reached for comment.The court ruled that although it was a citizens' initiative, Sanders' support of Prob B as policy warranted engagement with the unions under the Meyers-Milias-Brown Act, which gave city and county employees the right to collective bargaining in 1968.Governing bodies "or other representatives as may be properly designated" need to engage with unions "prior to arriving at a determination of policy or course of action," according to the act.Sanders had said he supported the measure as a private citizen, not a public employee. The Supreme Court ruled that Sanders did use the power of his office to push the initiative, however."He consistently invoked his position as mayor and used city resources and employees to draft, promote and support the Initiative. The city's assertion that his support was merely that of a private citizen does not withstand objective scrutiny," Corrigan wrote.In overturning the Public Employees Relations Board ruling in 2017, the appeal court took an "unduly constricted view of the duty to meet and confer," according to the Supreme Court ruling.The Supreme Court ruled that the appeal court address an "appropriate judicial remedy" for the illegal placement of the initiative on the ballot.The Public Employees Relations Board had previously ruled the city must pay employees "for all lost compensation" related to lost pension benefits, which would cost millions of dollars.The 401(k)-style system was originally intended to save taxpayers money by reducing future pension liabilities. Approved by 65 percent of voters, the system was the first of its kind among California municipalities. 2742
