 Climate change activist Greta Thunberg believes it is possible, in theory, to keep global warming below 1.5 degrees Celsius but says it's up to us if we want that to happen. The Swedish teenager has arrived in Glasgow ahead of the COP26 summit and she has no problem angering people as she contends it can be necessary as part of environmental demonstrations. I think as long as, of course, to make clear, as long as no one gets hurt, and as long as, yeah, then I think sometimes you need to anger some people. Like, for instance, the school strike movement would never have been so, would never have become so big if there wasn't friction, if some people didn't get pissed off. Thanks for watching, I'm Greta Thunberg and I'll see you in the next video.
