Inter-regional risks from climate change-also called cross-border, transboundary, transnational or indirect risks-are risks that are transmitted across borders  and/or via teleconnections  . The risks can result from impacts, including compound or concurrent impacts, that cascade across several tiers, in ways that either diminish or escalate risk within international systems . Risk transmission may occur through trade and finance networks, flows of people , biophysical flows  and ecosystem connections. However, not only risks are transmitted across borders and systems; the adaptation response may also reduce risks at the origin of the risk, along the transmission channel or at the recipient of the risk . This cross-chapter box discusses four inter-regional risk channels  and how adaptation can govern these risks.
