Climate change is commonly cast as a significant governance challenge demanding national and international actions. Subsequently, political science research tends to focus on the policy and politics of nation-states, their domestic institutions, and/or their interplay in international venues. However, thousands of industrial facilities and hundreds of subnational US governments are active in American climate risk governance. Therefore, we argue that more research should attend to climate governance’s subnational policy and politics, their promise, and their performance. In the vacuum of national policies to mitigate and adapt to climate-change, subnational arrangements offer an ideal opportunity to study not only the spontaneity …

Great Basin bristlecone pine (Pinus longaeva) at 3 sites in western North America near the upper elevation limit of tree growth showed ring growth in the second half of the 20th century that was greater than during any other 50-year period in the last 3,700 years. The accelerated growth is suggestive of an environmental change unprecedented in millennia. The high growth is not overestimated because of standardization techniques, and it is unlikely that it is a result of a change in tree growth form or that it is predominantly caused by CO2 fertilization. The growth surge has occurred only in …
