What is global warming?

Have you heard the term “global warming” a lot but don’t know exactly what it is? In this series, I’ll try to explain the basics of global warming in a way that’s easy to understand but backed by research you can review yourself. Hopefully, by the time you finish this post, you’ll have at least a generally better idea of what climate change / global warming is, why it’s a problem, and how you can have a small, but valuable, part in helping to try to remedy it.
