I came across with a video by International Ski Federation where elite winter athletes talk about climate change. While it is indeed a very good idea to increase the awaraness of this phenomenon, which is very critical for the success of our planet, I also started to wonder whether elite (winter) sport athletes are really the best persons to talk about preventing climate change.
This is because they are the persons that travel the most with airplanes all over the world to reach their training and competition destinations. Airplane travel is an important source of pollution promoting climate change, as discussed in detail for instance in this scientific paper, or by New York Times story (with lots of good links), which might be a bit easier to follow.
Unfortunately the video is a typical – lot of talk, no actions – promotion video. Hopefully International Ski Federation thinks also actions next time. In the meantime everyone can take their own actions for the matter by traveling being physically active rather than taking a car or airplane.
