The volume of climate science research being published each year continues to grow. Here, I chart the yearly growth up through 2025, based on a Web of Science search method outlined in a recent peer reviewed study (cited further below).
Why does this growth matter?
Well, for lots of reasons, but as a journalist, I see it in a particular context. I look at this huge mass of research and I think, *jeez, we in the press don’t cover anything more than a tiny fraction of that.*
So how do we decide what to cover?
How do we even know what we are missing?
Although I myself have written many of them, such questions have made me more skeptical of journalistic news stories written about single scientific studies. Not only are these stories inevitably selective in what they choose to cover; but this is also the kind of journalistic story that AI will increasingly be able to replicate. Just feed in one of these 15,000 studies, and tell it to write a news story.
The upshot is that journalists today have a lot of deep thinking to do about how they cover research, in light of A) how much of it there is now and also, B) the growing power of AI. I'm posting a longer essay I've just written about this, on Substack, in the first comment below.
