  • A study of the effect of radiative forcing, climate feedback and ocean heat uptake on global-mean surface temperature indicates that overestimation of the response of climate models to radiative forcing from increasing greenhouse gas concentrations is not responsible for the post-1998 discrepancy between model simulations and observations.

  • Poverty increases vulnerability to climate-related shocks and both drive migration decisions. In a laboratory-based economic game, Marotzke et al. find that the rich are unable to prevent migration by the poor, and increase their effort to avert climate change when the poor are hit by a climate event.

  • Climate simulations based on an ocean model may hold the key to understanding why existing climate models have failed to deliver a clear picture of ocean circulation during the last ice age.

  • Social dilemmas force players to balance between personal and collective gain. Here, inspired by the negotiations for greenhouse-gas emission limitations, the authors experimentally studied a representative-based collective-risk scenario, reporting the emergence of extortionate zero-determinant (ZD) strategies.

  • The role of temporal discounting in group decisions is poorly understood. A group experiment on collective risk in the context of climate change is used to analyse cooperative behaviour under different timeframes for the realization of the cooperation benefits. Results show that gains that are delayed significantly into the future—intergenerational discounting—markedly diminish cooperation.

  • Using an energy budget approach to understanding decadal temperature trends, this study highlights that observational uncertainty exceeds energy–flux deviations that affect such trends. Thus the origin of recent warming slowdown is unidentifiable.

  • Human activity is changing Earth's climate. Now that this has been acknowledged and accepted in international negotiations, climate research needs to define its next frontiers.

  • When the Marinoan snowball Earth deglaciated, the ocean’s chemistry determined the strength and duration of the ensuing supergreenhouse climate, while the sudden warming and biological activity could have led to a rapid formation of cap dolostones.

  • Greenhouse-gas forcing has previously been thought to be rather ineffective at destroying the habitability of Earth-like planets. Here, the authors show that CO2is as effective as solar forcing at causing a climate transition to a Moist-Greenhouse regime and thus poses an equal threat to a planet's habitability.

  • Uncertainty in estimates of future climate arises not only from internal variability, but also from model-to-model differences. Here, the authors use a new set of single model initial-condition large ensembles to quantify the contribution of model differences to the overall uncertainty in temperature and precipitation projections.
