Smith et al. (2007) Science, 317, 796-799, have published the results of a new modeling system that predicts both external forcings and internal variability leading to improved forecasts of climate in the next 10 years. Internal variability will partially offset anthropogenic warming until 2008/9. After this point, climate will continue to warm. Richard Kerr in the same issue of Science discusses the importance of natural climate variation e.g. Atlantic Multidecadal Oscillation (AMO) over the next few decades.
