To those who want to reinforce their understanding of the first principles of climate change science, here are a couple of straightforward explanations worth examining:
- The Carbon Cycle: this page from NASA’s Earth Observatory describes how carbon behaves in the atmosphere, hydrosphere (oceans), and lithosphere (rocks).
- The Greenhouse Effect: this page from the University Corporation for Atmospheric Research provides a basic description of what the greenhouse effect is.
Understanding these two basic areas of science is a fundamental prerequisite for being knowledgeable about climate change. The BBC also has a rather good website explaining the key concepts for laypeople.
