We consider the strategic role of uncertainty and information acquisition for the mitigation of global warming. Before the countries decide on their contribution to a mitigation of global warming, they may invest in information about the country-specific benefit of reductions of the emissions of greenhouse gases. We show that information acquisition has a substantial strategic value. Countries may prefer not to learn their benefit of climate protection even if information acquisition does not involve a direct cost. This strategic information choice may further decrease the efficiency of the public good provision.
