A study released earlier this year conducted by university researchers from both the UK and US indicated that climate change is causing more extreme rainfall events from hurricanes, specifically among Caribbean islands.The study was authored by researchers from Bristol University in the UK and MIT in the US.The researchers said that the focus on the study was on extreme rainfall from hurricanes, like Hurricane Dorian which, stalled over the Bahamas last year.“Overall, the results suggest that the Eastern Caribbean region in particular (Puerto Rico and the Dominican Republic) is likely to benefit from a reduction in extreme hurricane precipitation events resulting from increased efforts to stabilize global warming,” the study reads, pointing to the Paris Climate Accord as a benchmark for minimizing the impact of extreme rainfall events from hurricanes.The research found that events like Hurricane Maria, which struck Puerto Rico in 2017, would happen twice as frequently if sea surface temperatures increase by 2 Celsius instead of 1.5 Celsius, which is the goal of the Paris Climate Accord.In the case of Hurricane Dorian, an event like that could strike the Bahamas four to five times more frequently if sea surface temperatures increase by 2 Celsius instead of 1.5 degrees. A seemingly small difference could be what saves thousands of lives and billions of dollars in damage.One of the study’s authors told CBS News there is particular concern that the impact of extreme rainfall events could occur over poorer island nations in the Caribbean."The findings are alarming and illustrate the urgent need to tackle global warming to reduce the likelihood of extreme rainfall events and their catastrophic consequences, particularly for poorer countries which take many years to recover," Emily Vosper, a researcher at the University of Bristol, told CBS News.The full study is available here. 1912

A month after the deadliest mass shooting in America brought bump stocks to national attention, the rifle modification is again for sale and there's no regulation on the horizon.Slide Fire, the company that owns the patent on the rifle modification, said it has resumed taking new orders for bump stocks for the first time after temporarily suspending new sales a month ago."We will resume limited sales on November 1st at 8:30 a.m. CST," said Slide Fire, in an email from its customer services department to prospective buyers. "However, we have not yet reached adequate inventory levels to offer sales of all products."For most of October, the company kept a message posted to its homepage saying that sales of bump stocks were suspended.That suspension happened shortly after gunman Stephen Paddock used rifles fitted with bump stocks to commit the deadliest mass shooting in U.S. history on October 1 in Las Vegas. Using his 32nd floor suite at the Mandalay Bay hotel as a sniper's nest, he shot into an outdoor concert on the ground below, killing 58 people and wounding hundreds before taking his own life.Slide Fire did not return messages from CNNMoney asking about the change in their sales policy.Experts say demand for the product likely remained high during the period of suspended sales."I imagine they were able to fulfill the flurry of orders they received after the Las Vegas tragedy, but I would think demand is still far stronger than usual for them," said Rommel Dionisio, gun industry analyst for Aegis Capital Corp.Related: One month after mass shooting, still no restrictions on bump stocksBump stocks speed up the rate of fire for semi-automatic rifles to mimic fully automatic fire. The bump stocks harness the recoil of the gun to bump the shooter's finger against the trigger, causing it to shoot much faster than if the shooter was manually pulling his or her finger on the trigger.The Bureau of the Alcohol, Tobacco, Firearms and Explosives said it does not consider bump stocks to be firearms, but parts -- as explained in a 2010 letter that Slide Fire displays on its web site. Parts are not subject to federal gun control measures like background checks.The use of bump stocks in the mass shooting inflamed gun-control rhetoric, prompting even National Rifle Association, which generally opposes all forms of gun control, to suggest imposing "additional regulations." NRA executives also said the ATF should "immediately review whether these devices comply with federal law."A few days later, the NRA said it opposed bipartisan bills to ban bump stocks. NRA spokeswoman Jennifer Baker said the bills were "overreaching and would ban commonly owned firearms accessories."Related: Bump stocks sell briskly after mass shootingA month after the mass shooting, there's no regulations on bump stocks. On Tuesday, Sen. Chris Murphy, a Democrat from Connecticut who has been engaged in the gun debate on Capitol Hill for years, told CNN that he's heard nothing on whether the ATF is seriously looking at changing regulations surrounding bump stocks."I don't think the ATF is going to move unless the White House tells them to move and my impression is that they have been given no direction from the White House," Murphy said."It is unclear what the ATF can do," Murphy added.Kris Brown, co-president of the Brady Center to Prevent Gun Violence, said she's "pretty shocked that these kinds of accessories that are so easily used to transform a semi-automatic into a machine gun are still on the market."She said, "It's incredibly disappointing that even that marginal change isn't pushed through Congress overnight."The Brady Center filed a class action suit against Slide Fire Solutions "on behalf of all concert goers who suffered emotional distress as a result of the shooting that killed 58 people and wounded hundreds."The specter of gun control prompted a boost in sales for bump stocks, with various gun stores around the country telling CNNMoney they were rapidly selling out. Most were unable to restock because they couldn't get new inventory.FosTech Outdoors, which was selling bump stocks under the brand name Bumpski, also suspended taking new orders shortly after the Vegas shooting. FosTech, which has not returned messages from CNNMoney, no longer offers the bump stocks for sale on its web site.CNN's Daniella Diaz, Lauren Fox and Deirdre Walsh contributed to this report.The-CNN-Wire 4433

A New York taxi kingpin and business partner of President Donald Trump's attorney Michael Cohen has agreed to cooperate with the government, The New York Times reported Tuesday.The Times said the agreement for Evegny "Gene" Freidman would allow him to avoid jail time and would have him work with prosecutors in both the state and federal investigations.Word of the Freidman agreement came just days after news broke that Jeffrey Yohai, the son-in-law of former Trump campaign chief Paul Manafort, had reached a plea agreement.Freidman, known as New York's "Taxi King," was indicted on state charges last year by then-New York Attorney General Eric Schneiderman, who alleged Freidman and others failed to pay million in MTA surcharges between 2012 and 2015.Freidman's agreement, given his ties to Cohen as a business partner, may put still more pressure on the Trump associate and attorney, who faced federal raids in April before the Justice Department announced it had been conducting a months-long investigation into him.CNN previously reported the FBI searches included a request for documents related to Cohen's ownership of taxi medallions and sought informationabout taxi owners who had financial dealings with Cohen.Cohen's role as Trump's personal attorney has come under increasing scrutiny, due in large part to the payment he conceded facilitating to the adult film star Stormy Daniels. Trump attorney Rudy Giuliani later admitted that Trump had repaid Cohen.News of the raids in early April prompted Trump's outrage, as he called the searches "an attack on our country." 1659

A suburban Chicago police officer responding Sunday to a shooting at a bar killed a security guard who was just "doing his job," an attorney for the victim's family said.An officer from Midlothian, a Chicago suburb, fatally shot Jemel Roberson, a 26-year-old security guard working at the bar, Cook County Sheriff's Office spokeswoman Sophia Ansari told CNN.Several law enforcement agencies responded to the shooting around 4 a.m. at Manny's Blue Room Lounge in Robbins, about 20 miles south of Chicago, Ansari said. Three people and an alleged shooter were injured, she added.Then, after Roberson had apprehended an alleged gunman, the Midlothian officer shot Roberson outside the bar, according to a federal lawsuit filed Monday that calls the fatal shooting "excessive and unreasonable" and claims it violated Roberson's civil rights.Witnesses said security had asked several drunk men to leave the bar, and at least one person returned to the bar and opened fire, CNN affiliate WGN reported. A bartender was among the victims of that shooting, according to the lawsuit.After the shooting, Roberson "had somebody on the ground ... with his knee in back, with his gun in his back like, 'Don't move,'" Adam Harris, a witness, told WGN."We all yelled. 'He's a security. He's a security,' and without ... giving any thought, they shot him," Harris told the station. "The vest said security as well, ... and they shot him in the side." 1441
