- Assesses the extent to which observed large-scale changes in near-surface temperatures over the latter half of the twentieth century can be attributed to anthropogenic climate change as simulated by a range of climate models
- Rejects the hypothesis that observed changes are entirely due to internal climate variability at a high confidence level independent of the climate model used to simulate either the anthropogenic signal or the internal variability
- Concludes that the influence of anthropogenic greenhouse gases emerges as a substantial contributor to recent observed climate change, with the estimated trend attributable to greenhouse forcing similar in magnitude to the total observed warming over the 20th century
