Making It Count: Using Data to Tell Stories from the Climate Crisis

We are already seeing the impacts of the climate crisis, and many are so wide-ranging and devastating that they are difficult to comprehend. Many journalists are taking the skills and techniques of data journalism and applying these to the disastrous ramifications of climate change.

Much of the time, it is only through this work to bring forward the human stories that lie behind the numbers that we, as readers, are able to truly understand the ecological collapse our exploitation of the planet is causing. Four journalists talk through the methods they use to find, understand and tell these stories.

Gianluca also did the first comprehensive scientific overview (published in Le Scienze – Scientific American) of what PFAS – actually – are.
