It's said that "seeing is believing." I know that seeing can also be deceiving, particularly given the digital world we live in. It's also said that "a picture is worth a thousand words," and if the latter be so, then I'd say a good video is worth many thousands of words, as this one is.
I don't think you'll find any of this video digitally altered to be fake news, most unfortunately. Like many, I no longer waste time trying to convince "climate change deniers," any more than I would "flat earthers." Good god, I can't even believe they're still around!
I was about to say that this relatively short video, about ten minutes, "tells it like it is." But then I remembered the date it was produced, August 27, 2015. Given that we are indeed in abrupt climate change, it is now November, 2018, the Arctic sea ice is virtually gone, and damage, death, and misery reigns around the planet, I'd have to say it seems "beyond a wake-up call."
Here's a link to the actual page the video is from, which I post for anyone who wants to read the comments click here
