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.

At 16 years old, Gabe Richards has been working hard to get good grades.He's secured straight As while being a part of the special education program at Marysville High School in Michigan.But, after getting invited to be honored at an academic awards ceremony Monday night, Gabe said he was disappointed to be told at the event that his invite was a mistake."We were really excited and don't get the chance to celebrate achievements all the time," said his mother Stefanie Grassel.Grassel said the faculty did apologize and acknowledge they mistakenly sent an invitation letter.However, as a mother, Grassel said she wants to see the policy changed to become more inclusive."It sends the message that they are less than a general education student, and that's wrong," she added.Richards also told us he feels disappointed after what happened. District superintendent Shawn Whiteman refused to do an interview in response to what happened. Instead, he issued the following statement addressing the matter:"The criteria for students to receive the distinguished “Academic Award” from Marysville High School are a GPA greater than or equal to 3.5 and that they are enrolled in a certain amount of academic-based classes.After speaking with our high school principal, it was evident that a mistake was made when identifying students for this award, due to the fact that a letter was sent home inviting a student to the ceremony who didn’t meet the full criteria.It is clear that the high school made an error in identifying students for this year’s award and we respectfully apologize for any grief this has caused. Because of this, we will be taking corrective action so that this does not happen again in the future." 1768

At least one airline is starting to pull back on their cleaning regimen. Southwest crews are limiting their between-flight cleanings and leaving most of the passenger areas for the overnight cleaning crew, according to reports.Following the coronavirus outbreak in March and subsequent travel bans, airlines touted their stepped-up cleaning protocols as passengers returned.Starting in August, Southwest is focusing on lavatories and tray tables between flights, leaving seat belts, arm rests and other areas for the overnight cleaning crew, Southwest representative Ro Hawthorne told the Dallas Morning News."Since flight schedules have increased, other areas of the aircraft will be disinfected during our overnight cleaning process, when Southwest Teams spend six to seven hours per aircraft cleaning all interior surfaces," Hawthorne said in a statement.“As always, Southwest will monitor customer and employee feedback as we adapt to the new normal in air travel, while ensuring we keep safety as our top priority,” the statement continued.In March, Southwest announced their cleaning program included "interior windows and shades, every seat belt buckle, passenger service units (including the touch buttons that control reading lights and vents that direct personal air), as well as seat surfaces, tray tables, armrests, etc."The change to cleaning protocol will reduce the time an aircraft spends on the ground between flights, the airline told flight attendants in a memo obtained by CNN. 1505
