The preparation of the Assessment Reports on Climate Change is a key activity of the IPCC. We are now beginning the process towards our Fifth Assessment Report. The Fourth Assessment Report (AR4) was released in 2007, and it consists of four volumes: the three IPCC Working Groups (WGs) Reports and a Synthesis Report (SYR)..." [ More... ]
