A comparison of observations with simulations of a coupled ocean-atmosphere general circulation model shows that both natural and anthropogenic factors have contributed significantly to 20th century temperature changes. The model successfully simulates global mean and large-scale land temperature variations, indicating that the climate response on these scales is strongly influenced by external factors. More than 80% of observed multidecadal-scale global mean temperature variations and more… 

Long-term natural variability and 20th century climate change

Here it is presented a technique that objectively identifies the component of inter-decadal global mean surface temperature attributable to natural long-term climate variability that is monotonic, accelerating warming during the 20th century.

Improved Surface Temperature Prediction for the Coming Decade from a Global Climate Model

A new modeling system is presented that predicts both internal variability and externally forced changes and hence forecasts surface temperature with substantially improved skill throughout a decade, both globally and in many regions.

Are Natural Climate Forcings Able to Counteract the Projected Anthropogenic Global Warming?

A two-dimensional global climate model is used to assessthe climatic changes associated with the new IPCC SRES emissions scenarios and to determine which kind of changes in total solar irradiance and

Variability of high latitude amplification of anthropogenic warming

Climate models have long predicted that the high latitude response of near‐surface air temperatures should be greater than at lower latitudes as a result of snow/ice feedbacks. Here we show that a

Detection of a Human Influence on North American Climate

Comparison of index trends in observations and model simulations shows that North American temperature changes from 1950 to 1999 were unlikely to be due to natural climate variation alone, while observed trends over this period are consistent with simulations that include anthropogenic forcing.

Variation of surface temperature during the last millennium in a simulation with the FGOALS-gl climate system model

A reasonable past millennial climate simulation relies heavily on the specified external forcings, including both natural and anthropogenic forcing agents. In this paper, we examine the surface

Attribution of Recent Temperature Changes in the Australian Region

Variations of Australian-average mean temperature and diurnal temperature range over the twentieth century are investigated. The observed interannual variability of both is simulated reasonably well

Influence of various forcings on global climate in historical times using a coupled atmosphere–ocean general circulation model

The results of a simulation of the climate of the last five centuries with a state-of-the-art coupled atmosphere–ocean general circulation model are presented. The model has been driven with most

Impacts of external forcing on the 20th century global warming

The impacts of external forcing, including natural and anthropogenic, on the 20th century global warming were assessed with the use of the Grid Atmospheric Model of IAP/LASG Version 1.1.0, following

Detection and attribution of changes in 20th century land precipitation

Observed globally‐averaged land precipitation changes over the 20th century are compared with simulations of the HadCM3 climate model using an “optimal fingerprinting” method. We find that observed

Causes of global temperature changes during the 19th and 20th centuries

During the past two decades there has been considerable discussion about the relative contribution of different factors to the temperature changes observed now over the past 142 years. Among these

A 21st-century global warming projection far exceeds the natural variability of the past 1000 years and is greater than the best estimate of global temperature change for the last interglacial.

An analysis of historical sea surface temperatures provides evidence for global warming since 1900, in line with land-based analyses of global temperature trends, and also shows that over the same

Simulation of early 20th century global warming

Results from a set of six integrations of a coupled ocean-atmosphere climate model suggest that the warming of the early 20th century could have resulted from a combination of human-induced radiative forcing and an unusually large realization of internal multidecadal variability of the coupled Ocean-Atmosphere system.

CLIMATE models suggest that increases in greenhouse-gas concentrations in the atmosphere should have produced a larger global mean warming than has been observed in recent decades, unless the climate

The range of warming rates over the coming 50 years is assessed that is relatively robust to errors in the models' climate sensitivity, rate of oceanic heat uptake or global response to sulphate aerosols as long as these errors are persistent over time.
