“You have to listen to the scientists!!!”

To listen to them, support them, and relay their work, you should already follow them on Twitter. Why Twitter ? Because it is the network where scientists are the most present and communicate the most. Even scientists who interact on certain topics on Instagram, Linkedin or Youtube, are all on Twitter.

Scope and conditions

The objective of this article is to highlight the scientists who work on environmental and climate issues. There are probably brilliant people outside of these subjects, but without framing, we would have to list thousands of people!

Next, a few points and conditions to get your bearings:

• Categories: it is extremely difficult to make categories, to put a person in a box. To serve as a basis, the CNRS sections are useful.
• A list is necessarily incomplete, and subjective. Incomplete, because great scientists are not on Twitter, and it is difficult to have 100% of the people in the list. Subjective, because some scientists have sometimes had a tendency to express themselves on other fields and to say big stupidities, like Didier Raoult on the climate, or Claude Allègre.
• The French language is preferred, even if most scientists use English on Twitter. If you are lucky enough to speak English, here is a list. If not, this is a good opportunity to get started!
• There are some excellent teachers/politics who are not on this list. But choices must be made!
• There is no hierarchy or order, from the first to the last version.
• You can also make “lists” on Twitter, by keywords, etc. Here is a very useful tutorial.

Finally, feel free to leave a comment to add/remove your name or update your exact title, it is not always up to date on all sites! And remember that listening to scientists will not solve all the problems…
