There age tons of factual articles about climate change. Though it does not interest many people.

Kudos for those guys for trying to tell the story differently in a hope to reach a broader audience.

Well, it is a story. Obviously the medium is designed to engage readers. This is not a scientific paper.

Seeing is believing, i think the UX with tons of pictures actually help the credibility and impact of the story.

I think they choose the right medium for the message.

I agree, this is more of a slideshow than an article, and I don't think having it as an article with pictures would make it more plausible. The pictures tie in neatly with the content in a way that doesn't annoy me as much as other similar experiences have.

It is told as a story, to engage the reader. It is very well presented. Perhaps you can do better, are you a journalist or a UX designer?

Journalists are usually not the ones who make UX decisions.
