BERLIN (AP) — The United States has formally left the Paris Agreement, a global pact forged five years ago to avert the threat of catastrophic climate change. Wednesday's move was long threatened by U.S. President Donald Trump and triggered by his administration a year ago. It further isolates the United States in the world but has no immediate impact on international efforts to curb global warming. There are 189 countries remain committed to the 2015 accord, which aims to keep the increase in average temperatures worldwide “well below” 2 degrees Celsius compared to pre-industrial levels. Scientists say that any rise beyond 2 degrees Celsius could have a devastating impact on large parts of the world, raising sea levels, stoking tropical storms and worsening droughts and floods. 797

BRUCE TOWNSHIP, Michigan — A company that supplies equipment to the University Hospitals fertility center said its storage tank did not malfunction. “The early stages of our investigation into this unfortunate incident indicate it was the result of human error,” Custom Biogenic Systems said in a detailed statement sent to E.W. Scripps Co. TV station WEWS in Cleveland, Ohio.In a letter to patients on March 26, University Hospitals said that a remote alarm system on a storage tank that was designed to alert a University Hospitals employee to changes like temperature swings was turned off. UH said that on the evening of Saturday, March 3, the temperature inside the tank, which contained thousands of eggs and embryos, rose. UH does not know when the alarm was turned off. During the period when the alarm was off, UH said it had been experiencing “difficulty with what is called the liquid nitrogen automatic fill on the storage tank” for “several weeks.” Liquid nitrogen is added to the storage tank to keep specimens frozen, and it can be added manually or automatically. According to UH, “We had been working with the tank manufacturer who had previously provided instructions on the necessary maintenance to ‘thaw’ the storage tank to correct this difficulty. To do that required transferring all specimens to an extra storage tank previously provided by the manufacturer. This process takes several weeks, and had begun when this event occurred, though no eggs or embryos had yet been moved to the extra tank.”Custom Biogenic Systems, of Bruce Township, Mich., says the extra tank was available to UH on Aug. 15, 2017, UH finalized its arrangements for delivery of the tank on Oct. 27, 2017, and the tank was delivered on Nov. 2, 2017. That’s almost four months to the day before 950 UH patients lost 4,000 eggs and embryos in an event the hospital would later call “catastrophic." With the automatic fill not working on the original tank, UH added liquid nitrogen to the tank manually. This was done by connecting the storage tank with a line to a tank of liquid nitrogen from the Embryology Lab. But, according to UH, “For several days prior to the weekend in question, a manual fill could not be done using the line in the Embryology Lab because there were no liquid nitrogen tanks available. So, containers of liquid nitrogen were obtained from the Andrology Lab. Those containers were then manually poured into the top of the tank, while amounts of liquid nitrogen and temperature were monitored.” Custom Biogenic Systems says its tank is not designed to be filled by liquid nitrogen poured into the top of the tank.The company said its product manual states:  2744

BRUNSWICK, Ga. (AP) — A Georgia judge has denied bond for the white father and son charged with murder in the February slaying of Ahmaud Arbery.Superior Court Judge Timothy Walmsley said Friday that he's concerned Gregory McMichael and his adult son, Travis McMichael, took the law into their own hands and endangered neighbors when they pursued the 25-year-old Black man with guns and shot him in a residential street in February.Defense attorneys say the McMichaels had reason to suspect Arbery was a burglar and Travis McMichael was defending himself when he shot Arbery in the port city of Brunswick.During a hearing Thursday, prosecutors said Travis McMichael had previously used racial slurs in text messages and on social media.Prosecutors asked the suspect’s friend, Zachary Langford, on the witness stand about a text in which McMichael used a slur for Black people. At first, he said he didn’t recall receiving the message, but after reviewing a transcript of the exchange, he said “He was referring to a raccoon, I believe,” The Associated Press reports.Attorneys for the McMichaels have died any racist motives in the shooting.The McMichaels were not arrested until May, when the Georgia Bureau of Investigation stepped and charged them with murder and aggravated assault.There was mounting public pressure for justice in the case after video was released of the deadly incident. The case gained attention nationwide during the summer’s protests over racial injustice.The man who filmed the video, William Bryan, was also later arrested and charged with murder and criminal attempt to commit false imprisonment, according to The New York Times.In June, The Times says a grand jury returned an indictment with nine counts against all three men. Those charges include malice murder, four counts of felony murder, two counts of aggravated assault, false imprisonment and criminal attempt to commit false imprisonment. 1934

Billowing smoke from wildfires on the West Coast is reaching cities thousands of miles away, and those who live closer to the fires are battling hazardous air for weeks now.“We’ve never seen anything like this. Waking up to orange light pouring in your room is such an eerie feeling,” said Danica Gragg. “We’ve never seen anything like it.”As wildfires scorch millions of acres, blue skies are transformed into rust, making earth appear more like Mars.We haven’t even been able to see the sun for a couple weeks,” said Gragg.Located east of San Francisco, unpredictable fires have dictated her family's lives for weeks now. First, it was the fear of evacuating.“There were three different fires at the time when this started: one above us, one below us, one to the right.”Ultimately spared from the flames, her family would still feel the wrath of what’s left in their wake.“My dad is a disabled veteran with COPD,” she said.Suffering from a chronic lung disease, it was the first time the Vietnam veteran found himself completely unable to breathe while taking out the trash one evening.“The ambulance came and of course with COVID, I think that was the first time I really understood what people were going through when you have to see a loved one taken away in an ambulance and you can’t go with them. You don’t know when you’ll see them again,” Gragg said.He was hospitalized for six days.Gragg said her family got humidifiers and also downloaded apps to check air quality. The apps reveal that West Coast cities are suffering from some of the worst air in the world, with San Francisco, Portland and Seattle ranking in the top five.“We can see the atmosphere in totally new ways now, and I have never personally seen so much smoke across the west as I did last week,” said Geoff Cornish, a meteorologist with AccuWeather.Satellite images show choking smoke blanketing the west and moving across the U.S. and Pacific Ocean.“Most of the smoke, as it gets carried east of northern plains, is elevated, and that will be high in the atmosphere,” said Cornish. “Now, somebody who might be really susceptible to respiratory illnesses might sense some of that.”What makes wildfire smoke so toxic is fine particulate matter so small it can get deep into the lungs and bloodstream. It's a public health threat that grows with each destructive wildfire season.“Climate change is not something that should be debatable anymore,” Gragg said. “We can see it. We need to listen to the scientists. They told us this was coming.”And now, her family waits to see how many more days will be dictated by historic fires raging around them. 2631

BATON ROUGE, La. — The governing council in Baton Rouge, Louisiana, has again rejected a proposed million settlement in a lawsuit over the death of Alton Sterling, a Black man fatally shot by a white police officer in 2016. The 12-member East Baton Rouge Metro Council fell one vote short of the seven needed for approval Wednesday. It was the council's third rejection of a possible settlement, and it makes a March 2021 trial more likely in the wrongful death lawsuit filed on behalf of Sterling's five children. Sterling was shot six times on July 5, 2016, in a confrontation with police that was recorded on two cellphone videos and widely seen online. 667
