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

The hydrology of the humid tropics
Hydrological processes in the humid tropics differ from other regions in having greater energy inputs and faster rates of change, including human-induced change. Human influences on population growth,

Impact of intensified Indian Ocean winds on mesoscale variability in the Agulhas system
South of Africa, the Agulhas Current retroflects and a portion of its waters flows into the South Atlantic Ocean, typically in the form of Agulhas rings. This flux of warm and salty water from the Indian

Harmful filamentous cyanobacteria favoured by reduced water turnover with lake warming
Anthropogenic-induced changes in nutrient ratios have increased the susceptibility of large temperate lakes to several effects of rising air temperatures and the resulting heating of water bodies. First,

Decline of forereef corals in response to recent warming linked to history of thermal exposure
Rising ocean temperatures have reduced rates of coral calcification and increased rates of coral mortality, thereby negatively impacting the health of coral reef ecosystems. Nevertheless, the response

Human-induced global ocean warming on multidecadal timescales
Large-scale increases in upper-ocean temperatures are evident in observational records. Several studies have used well-established detection and attribution methods to demonstrate that the observed basin-scale

Brazil takes centre stage
The Rio+20 conference (20–22 June 2012) will be held in Rio de Janeiro, Brazil. It will focus on two main themes — development of a green economy while fostering sustainable development and poverty eradication,

Managing exposure to flooding in New York City
Writing in Nature Climate Change, Lin and colleagues show that the combined effect of storm climatology and sea-level rise will greatly shorten surge-flooding return periods. Future climate effects may

Assessing climate risks to UK agriculture
In January 2012, the first Climate Change Risk Assessment (CCRA) report was presented to the UK government to inform national adaptation policy. Regarding the agricultural sector, we and our colleagues

Rio+20 and Brazil's policy on climate change
As host to the Rio+20 United Nations Conference on Sustainable Development, Brazil will draw international attention to its policy on climate change, but the measures announced so far are not commensurate

Shortcomings in wheat yield predictions
redictions of a 40–140% increase in wheat yield by 2050, reported in the UK Climate Change Risk Assessment, are based on a simplistic approach that ignores key factors affecting yields and hence are seriously
