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

Betting on negative emissions
Bioenergy with carbon capture and storage could be used to remove carbon dioxide from the atmosphere. However, its credibility as a climate change mitigation option is unproven and its widespread deployment
-
Sharing a quota on cumulative carbon emissions
Any limit on future global warming is associated with a quota on cumulative global CO2 emissions. We translate this global carbon quota to regional and national scales, on a spectrum of sharing principles

Modelled glacier response to centennial temperature and precipitation trends on the Antarctic Peninsula
The northern Antarctic Peninsula is currently undergoing rapid atmospheric warming. Increased glacier-surface melt during the twentieth century has contributed to ice-shelf collapse and the widespread

Climate model simulations of the observed early-2000s hiatus of global warming
The slowdown in the rate of global warming in the early 2000s is not evident in the multi-model ensemble average of traditional climate change projection simulations1. However, a number of individual ensemble

Contribution of natural decadal variability to global warming acceleration and hiatus
Reasons for the apparent pause in the rise of global-mean surface air temperature (SAT) after the turn of the century has been a mystery, undermining confidence in climate projections. Recent climate model

Recently identified microbial guild mediates soil N2O sink capacity
Nitrous oxide (N2O) is the predominant ozone-depleting substance and contributes approximately 6% to overall global warming. Terrestrial ecosystems account for nearly 70% of total global N2O atmospheric

Importance of food-demand management for climate mitigation
Recent studies show that current trends in yield improvement will not be sufficient to meet projected global food demand in 2050, and suggest that a further expansion of agricultural area will be required.

Human land-use-driven reduction of forest volatiles cools global climate
Human conversion of forest ecosystems to agriculture is a major driver of global change. Conventionally, the impacts of the historical cropland expansion on Earth’s radiation balance have been quantified

A systems approach to evaluating the air quality co-benefits of US carbon policies
Because human activities emit greenhouse gases (GHGs) and conventional air pollutants from common sources, policy designed to reduce GHGs can have co-benefits for air quality that may offset some or all

Seasonal aspects of the recent pause in surface warming
Factors involved in the recent pause in the rise of global mean temperatures are examined seasonally. For 1999 to 2012, the hiatus in surface warming is mainly evident in the central and eastern Pacific.
