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

Climate risks across borders and scales
Changing climates are outpacing some components of our food systems. Risk assessments need to account for these rates of change. Assessing risk transmission mechanisms across sectors and international

A revival of Indian summer monsoon rainfall since 2002
A significant reduction in summer monsoon rainfall has been observed in northern central India during the second half of the twentieth century, threatening water security and causing widespread socio-economic

In the observational record half a degree matters
Discriminating the climate impacts of half-degree warming increments is high on the post-Paris science agenda. Here the researchers argue that evidence from the observational record provides useful guidance

Global risk of deadly heat
Climate change can increase the risk of conditions that exceed human thermoregulatory capacity. Although numerous studies report increased mortality associated with extreme heat events, quantifying the

A global economic assessment of city policies to reduce climate change impacts
Climate change impacts can be especially large in cities1, 2. Several large cities are taking climate change into account in long-term strategies3, 4, for which it is important to have information on the

Understanding the regional pattern of projected future changes in extreme precipitation
Changes in extreme precipitation are among the most impact-relevant consequences of climate warming, yet regional projections remain uncertain due to natural variability and model deficiencies in relevant

Climate negotiators’ and scientists’ assessments of the climate negotiations
Climate negotiation outcomes are difficult to evaluate objectively because there are no clear reference scenarios. Subjective assessments from those directly involved in the negotiations are particularly

Influence of high-latitude atmospheric circulation changes on summertime Arctic sea ice
The Arctic has seen rapid sea-ice decline in the past three decades, whilst warming at about twice the global average rate. Yet the relationship between Arctic warming and sea-ice loss is not well understood.

Towards a rain-dominated Arctic
Climate models project a strong increase in Arctic precipitation over the coming century, which has been attributed primarily to enhanced surface evaporation associated with sea-ice retreat. Since the

Species’ traits influenced their response to recent climate change
Although it is widely accepted that future climatic change—if unabated—is likely to have major impacts on biodiversity, few studies have attempted to quantify the number of species whose populations have
