Philosophy of climate change: models, problems and uncertainties

The objective of this article is to show the problems in the philosophy of science that climate change researchers are faced. The topic of the theoretical load of observation appears within the field as an indispensability of theoretical models in the detection and attribution of climate change. The empirical underdetermination of the models is accompanied by an uncertainty of values in both instrumental series and secondary data, and a structural uncertainty related to the specification of the couplings and radiative forcings. The realism of global models is also examined in connection with their calibration and climate projections.
