If you have questions about something, pose them on the FAQ section
or bring it up in a discussion (or even better, both!). If you understand everything we've written, try to find some other resources to familiarize yourself with. The IPCC report is not a bad thing to take a look at. There is always new research on this stuff, so there is sure to be something for you to learn (we know we are constantly learning new things). You can also keep up on the Climate Change news section.
