That set what seemed an impossibly high scientific bar at the time because researchers hadn’t yet fully identified the impacts of greenhouse gas emissions from specific projects on threatened species. But science has cleared that hurdle, said Steven Amstrup, an adjunct biology professor at the University of Wyoming and co-author of a new peer-reviewed paper in Science that could help “close the loophole” in the Endangered Species Act by showing how emissions from new projects on federal lands result in more days during which polar bears can’t feed because of declining sea ice.

Another great use for an Echo Dot is adding voice-command capabilities to a total home theater upgrade, like the immersive VIZIO Elevate, which is currently available on Amazon for $698, typically $1,099 and its lowest price ever. This 5.1.4 Dolby Atmos set-up (the pinnacle of the best VIZIO soundbars) has unique rotating speakers that help direct audio to form a 360-degree bubble around the listener. And plugging an Echo Dot into the auxiliary port will add even another dimension to the experience.
