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.

AUSTIN, Texas (AP) — Democratic presidential candidate Beto O'Rourke says President Donald Trump should resign as Congress begins an impeachment investigation.O'Rourke said Saturday there shouldn't be a fear of an impeachment probe intensifying partisan divisions. The former Texas congressman said at the Texas Tribune Festival in Austin that he believes impeaching Trump would ultimately unify the country.But O'Rourke says "the best thing" Trump can do at this point is to step down. Trump defiantly denies any wrongdoing.The 2020 Democratic presidential field is unanimous in its support of Congress for launching an impeachment investigation. The White House's handling of Trump's calls with foreign leaders is at the heart of the House impeachment inquiry.O'Rourke has been lagging in the polls but says he's in the race "until the very end." 856

As we head into the final days of the campaign, the environment is a major issue that perhaps does not get as much attention as others. COVID-19, the economy, and health care all are polling more important for most voters. But for some, the environment remains top of mind. "The environment is like the basis of everything," Anna Rose Mohr-Almeida, an 18-year-old voter in Arizona, said. "If we keep relying on oil, we aren’t going to make a clean transition," Mohr-Almeida said. Other voters are watching environmental policy more closely. Not because they want more reform, but because they worry about regulations that are too drastic. "We like clean air, we like clean water," Alan Olson with the Montana Petroleum Association said. "We have got a tremendous economy in the United States, primarily due to cheap fuel," Olson said. "Environmental regulations have to be realistic," Olson added. BIDEN VS TRUMPOn nearly every policy, the two presidential candidates differ, but it is especially apparent when it comes to the environment. During his administration, President Donald Trump has reversed nearly 100 environmental regulations. Trump removed the United States from the Paris Agreement, which is meant to stop rising temperatures by cutting emissions. The president is however committed to planting trees and did sign the Great American Outdoors Act, which Democrats and Republicans both believe will help protect federal lands for generations. Joe Biden, meanwhile, would immediately have the United States rejoin the Paris Agreement. Biden is committed to spending trillions to hire millions to create a "green economy."Biden wants net-zero emissions by 2050. While Biden has called the Green New Deal a framework, he has said he would not ban fracking. 1777
