In 1990 the First Assessment Report of the Intergovernmental Panel on Climate Change was produced. It contained a prediction of the global-mean-temperature trend for 1990–2030 which, halfway through that period, appears accurate. This is remarkable in hindsight, considering a number of important external forcings were not included. This study concludes the greenhouse-gas-induced warming is largely overwhelming the other forcings.
