As the Copenhagen Climate Conference is taking place, it is appropriate to clarify once again what is more or less accurately known about the climate of our planet and about climate change.

Obviously, a brief post can not substitute for detailed studies of professionals in a variety of scientific disciplines – climatology, atmospheric physics, chemistry, geology, astronomy, and economics. However, a short post can summarize basic theses on the main trends in climate evolution, on its forecasts, and on its actual and projected effects.
