As the polar ice caps retreat, polar bears could struggle to survive by the end of this century, a number of university researchers wrote in a study published in the Nature Climate Change journal.The study looked at a number of sub-species of polar bears who live in the arctic and how they have adapted to reduced sea ice from 1979 to 2016. The group of researchers said that all but a few sub-species of polar bears will be able to reproduce and survive given projected conditions by 2100.Polar bears use sea ice to capture seals for food. When sea ice erodes for the summer, polar bears fast. Although polar bears are capable of fasting for months, there are limits to how long the bears can go without food.The researchers examined energy needs of polar bears, and that the amount of time polar bears would fast would lengthen to a point that makes it too challenging to survive and reproduce.While resting female polar bears can generally fast for longer periods of time, reproducing females, males and cubs all require shorter fasting periods, the research found.“Avoiding continued sea-ice decline requires aggressively mitigating greenhouse gas rise,” the researchers wrote, “and our results explicitly describe the costs to polar bears of avoiding that mitigation.”To illustrate how much sea ice is being lost, NOAA is projecting that the arctic could have ice-free summers by 2042.Scientists have long discussed the possibility that polar bears could become nearly extinct by the end of the century. Beyond reducing carbon emissions, proposals have included relocating cubs to areas of the Arctic expected to retain higher levels of sea ice have been proposed.

As the debate over guns continues in Washington and in communities across the country, there's at least one place where owning a gun is technically required by law.In Kennesaw, Georgia, local law says that "every head of household residing in the city limits is required to maintain a firearm.""If you're going to commit a crime in Kennesaw and you're the criminal -- are you going to take a chance that that homeowner is a law-abiding citizen?" asked Kennesaw Mayor Derek Easterling.Wayne Arnold is one of those citizens. Among the weapons he keeps at home are an AR-15-style .223 caliber rifle, a variety of handguns and more."It gives me the ability to protect myself as opposed to being somewhere where you weren't allowed to have a firearm or it was frowned upon," said Arnold."More or less a political statement" 826

As the end of an incredibly contentious and the heated 2020 election season ends, new research suggests that Americans are more susceptible to falling prey to disinformation depending on which state they call home.For months, Bhaskar Chakravorti and his team at the Global Business School at Tufts University have been analyzing how misinformation has been spreading during this election cycle. Where a person lives often makes them a higher target to everything from fake Facebook accounts to fake Twitter accounts and even fake headlines."We are in extremely more dangerous territory now than we were two years ago," Chakravorti explained.Bad actors, the analysis found, are more likely to target people in states that are either facing hotly contested Presidential or Senate races. Chakravorti says in places like Florida, South Carolina, Kentucky, Montana and Arkansas, voters are more vulnerable to being hit with misinformation. In places like Georgia, Illinois, New Jersey and Minnesota, residents are less likely to be bombarded by false or misleading posts and stories.A person's age, education level and media consumption all weigh into the findings.Chakravorti also says that misinformation is more likely to spread and gain traction on social media."The misinformation is asymmetric in its power,” he explained. “It travels further and faster than truth and facts."Most troublesome right now, the amount of misinformation spreading about voting, from fake stories claiming people can vote after Nov. 3 to false information about mail-in ballot deadlines. Experts also say the spread of misinformation will likely continue long after Election Day.The non-profit Common Cause has also been studying the issue closely."It can result in more uncertainty when there’s already a decrease in the institutional trust and authority that many people feel with their government," said Jesse Littlewood, who works with the group.So, what's the best way to combat misinformation?Do it on the local level. People are more likely to trust information that comes directly from their city or state officials, especially about voting."It’s a real challenge for voters to stay abreast with all that changing information," Littlewood said. 2239
