In order to identify contributions from human caused anthropogenic forcings (mainly an increase in greenhouse gases) and natural causes (internal climate variability over the Pacific Ocean) to the observed IPWP warming and expansion, they used multiple climate model simulations integrated with and without human influences, and compared simulated changes in the IPWP with the observations using a sophisticated «fingerprinting» technique.
