<p>Existing studies have demonstrated substantial and robust effects of temperature shocks on economic growth, agricultural output, labor productivity, conflict, and health.&#160;These studies help clarify the impacts of climate change on social and economic systems, yet the relationship between climate shocks and political outcomes are less well identified.&#160;What effect do climate shocks have on states' climate policies?&#160;In this paper, I estimate the relationship between national-level temperature and rainfall shocks and the supply and demand for international climate governance.&#160;Temperature shocks may increase the salience of climate change in national politics and lead political leaders to adjust policies to match.&#160;Similarly, temperature shocks may have material consequences that induce adaptation---one avenue being to use international institutions to coordinate a global response to climate impacts.&#160;I argue that the responsiveness of national governments to climate shocks is conditioned by the political and natural context in which governments operate.&#160;Specifically, I expect that democratic governments will be more responsive to climate shocks, as will countries that are more vulnerable to the impacts of climate change.&#160;I assess whether countries that experience more frequent and more severe climate shocks participate more in international climate politics and adjust their climate policies.&#160;I examine four sets of outcomes at the national level: (1) membership in international institutions that govern climate change, (2) the provision and receipt of climate finance, (3) representation at the UN climate conferences, and (4) national climate policies.&#160;As the climate changes, we are developing stronger evidence about the underlying natural relationships, but the heterogenous effects across socio-political contexts are less well understood.&#160;This paper contributes to our understanding of how climate change shapes national policy and with it the ability of countries to manage and adapt to climate change.</p>
