I will review the basic physical principles underlying the behaviour of the earth's climate system. I will then review the evidence for human impact on climate over the past century, and climate change projections for the next century based on various possible fossil fuel emissions scenarios. I will discuss some of the current limitations, and will highlight the role of physics in resolving some of the key remaining uncertainties.
