The website skepticalscience.com presents most of the most common myths and misconceptions about climate change that are regularly used to stop or muddy conversations about climate change science. It does a great job explaining the science, and offers multiple levels of explanation, from basic to advanced. Most importantly, all of the materials are linked to peer reviewed literature, the site is run as a nonprofit, and many of the world's top climate scientists use it regularly and endorse the site. This is my go to for good explanations about complicated aspects of climate change.
The website https://climate.nasa.gov/ provides a lot of background information about climate change, all of which is illustrated with breathtakingly beautiful and often concerning images of our planet.
In my work on coastal climate change, I use this website from NOAA https://coast.noaa.gov/slr/ all the time. It lets you see past and predicted changes in sea level and flooding and it also allows you to look at which communities and ecosystems are most at risk.
Finally, if you are looking for a great entry primer, I think the New York Times did a phenomenal job with this data supported explainer - https://www.nytimes.com/article/climate-change-global-warming-faq.html
