Solution to cloud riddle reveals hotter future

Global average temperatures will rise at least 4°C by 2100 and potentially more than 8°C by 2200 if carbon dioxide emissions are not reduced according to new research published in Nature that shows our climate is more sensitive to carbon dioxide than most previous estimates. The research could solve one of the …

E.8 Climate Stabilization, Climate Change Commitment and Irreversibility

Cumulative emissions of CO2 largely determine global mean surface warming by the late 21st century and beyond (see Figure SPM.10). Most aspects of climate change will persist for many centuries even if emissions of CO2 are stopped. This represents a substantial multi-century climate change commitment created by past, present and …

New scenarios – SPM.1: Representative Concentration Pathways (RCPs)

Climate change projections in WGI require information about future emissions or concentrations of greenhouse gases, aerosols and other climate drivers. This information is often expressed as a scenario of human activities, which are not assessed in this report. IPCC WGI scenarios have focused on anthropogenic emissions and do not include …

El Nino events get more extreme as globe warms

Monday, October 28, 2013: New research shows El Niño Southern Oscillation (ENSO) phenomena have been more active and intense during the 30-year period between 1979-2009 than at any time during the past 600 years. At the same time, this result suggests that the intensity and activity of El Niño and La …
