Extremes become routine in an emerging new Arctic
This study shows how the Arctic is transitioning from a dominantly frozen state.Read More →
Extreme heat and stock market activity
Empirical analyses show that, on average, trading volumes fall significantly (between 4% and 10%) when maximum daily temperatures exceed 30 °C (86 °F).Read More →
Quantifying national responsibility for climate breakdown: an equality-based attribution approach for carbon dioxide emissions in excess of the planetary boundary
This analysis proposes a novel method for quantifying national responsibility for damages related to climate changeRead More →
The contribution of global aviation to anthropogenic climate forcing for 2000 to 2018
Global aviation contributes a few percent to anthropogenic radiative forcing. Comprehensive and quantitative calculations of aviation effects are presented.Read More →
Human contribution to the record-breaking June and July 2019 heatwaves in Western Europe
This peer-reviewed study examined two extreme heatwaves in Western Europe in 2019, finding that their frequency and intensity were influenced by climate change.Read More →
Anthropogenic Climate Change and Glacier Lake Outburst Flood Risk: Local and Global Drivers and Responsibilities for the Case of Lake Palcacocha, Peru
Analysis of lake Palcacocha's case in the Andes of Peru, which offers a representative model for other glacier lakes and related risks around the world because it features a dynamic evolution of flood risk driven by physical and socioeconomic factorsRead More →
Anthropogenic warming forces extreme annual glacier mass loss
Glacier mass balance is simulated using temperature and precipitation from multiple climate model ensembles. The authors estimate extreme mass loss was six (2011) and ten (2018) times more likely to occur with anthropogenic forcing than without.Read More →
Extinction risk assessment of a Patagonian ungulate using population dynamics models under climate change scenarios
Huemul population is currently in a quasi-extinction process, with extinction probabilities increasing with climate change.These results are crucial for conservation of species like huemul that have low densities and are threatened by climate change.Read More →
Fingerprints of external forcing agents on Sahel rainfall: aerosols, greenhouse gases, and model-observation discrepancies
Using multiple characteristics of Sahel precipitation, the study constructs a multivariate fingerprint that allows to distinguish between the model-predicted responses to greenhouse gases and anthropogenic aerosols.Read More →
The effects of anthropogenic and volcanic aerosols and greenhouse gases on twentieth century Sahel precipitation
This study simulations highlight the importance of anthropogenic and volcanic aerosols over GHG in generating forced Sahel rainfall variability in models.Read More →
