It's interesting to see how big consequences small environmental changes can have. I bet this is just scratching the surface, and there are many new discoveries to come.
Your article somehow reminded me about an article I read about wolves bring aspen trees back in Yellowstone. Just small changes that have big effects (both negative and positive).

Yeah you're right about that. The temperature has generally "only" risen a few degrees in certain spots, but I cannot stress enough how big of a deal this actually is. A two degree average increase for an ecosystem is more than enough to change a lot of interactions there, potentially changing or destroying all of it. This small temperature is almost not sensed by us humans, but it's terrible for so many species.
The story of how the wolves changed so much in Yellowstone is such a cool read, and it is a very good example of how a little change can do so much. I am afraid that we will see a lot of these stories in the next 20 years once the consequences of the altered ecosystems begin to take real effect.
Thanks again for stopping by and leaving a valuable comment, @dieterschneider!
