ClimateSnack is a community that has been set up to help develop the written communication skills of climate research students and early career scientists on a continuous basis. The focus is on communicating bite-sized pieces of climate science in a simple and interesting way, by writing short pieces, or 'Snacks', that explain one's ideas to other researchers worldwide.

These are initially discussed in local writing groups, and are then made available to the whole community through the ClimateSnack website. The meetings of the group are held on a monthly basis, so the time commitment required of the participants is minimal.

There are already well-established writing groups at 7 universities in Norway, the UK and the US.
