There is an overwhelming amount of information about climate change online, and finding reliable sources can be a challenge. So, we’ve identified some of the best and most authoritative sources of climate change information below, as well as a number of reputable, free, online climate change courses. Take a look at these before deciding whether you need to pay for ours.

The image above shows a visualisation of global mean surface temperature from 1850-2019, and is a great example of some of the visualisations available from the sources below, in this case Climate Lab Book.

Online courses

The following courses are free, although in some cases this means you can only view course materials and cannot undertake exercises, interact with trainers or obtain a certificate. Check to see what is included in the free package and whether there are any additional costs associated with the full course experience. This list is far from exhaustive. You can find another, similar list on the Youth Climate Leaders website here. Coursera also lists many more climate change courses, and it’s worth searching for ‘climate change’ on their website to see what comes up.
