Country-level social cost of carbon
The social cost of carbon (SCC) is a commonly employed metric of the expected economic damages from carbon dioxide (CO2) emissions. Although useful in an optimal policy context, a world-level approach

Changing social contracts in climate-change adaptation
Risks from extreme weather events are mediated through state, civil society and individual action. We propose evolving social contracts as a primary mechanism by which adaptation to climate change proceeds.

Water at a crossroads
Climate and water expert Pavel Kabat — director and CEO of the International Institute for Applied System Analysis in Austria — calls for a long-term system approach to water research, new partnerships

Catchment productivity controls CO2 emissions from lakes
Most lakes are oversaturated with CO2 and are net CO2 sources to the atmosphere, yet their contribution to the global carbon cycle is poorly constrained. Their CO2 excess is widely attributed to in-lake

Adaptation of US maize to temperature variations
High temperatures are associated with reduced crop yields and predictions for future warming have raised concerns regarding future productivity and food security. However, the extent to which adaptation

Equity and state representations in climate negotiations
Current United Nations structures are highly inequitable and obstruct progress towards international climate policy cooperation.

EU climate leadership under test
Doha marks the first stop on a roadmap to a post-2020 climate regime. The European Union could pave the way by building bridges with partners in key areas such as mitigation ambition, adaptation finance

Climate-change impacts on understorey bamboo species and giant pandas in China’s Qinling Mountains
Climate change is threatening global ecosystems through its impact on the survival of individual species and their ecological functions. Despite the important role of understorey plants in forest ecosystems,

Mitigation of nitrous oxide emissions from soils by Bradyrhizobium japonicum inoculation
Nitrous oxide (N2O) is a greenhouse gas that is also capable of destroying the ozone layer. Agricultural soil is the largest source of N2O. Soybean is a globally important leguminous crop, and hosts symbiotic

Assessment of groundwater inundation as a consequence of sea-level rise
Strong evidence on climate change underscores the need for actions to reduce the impacts of sea-level rise. Global mean sea level may rise 0.18–0.48 m by mid-century and 0.5–1.4 m by the end of the century.

Evidence of the dependence of groundwater resources on extreme rainfall in East Africa
Groundwater recharge sustains the groundwater resources on which there is global dependence for drinking water and irrigated agriculture. For many communities, groundwater is the only perennial source
