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 …

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 …

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 …

Algorithm finds missing phytoplankton in Southern Ocean

This video shows the concentration of phytoplankton observed by satellites in the Southern Ocean over the summer months.   TUESDAY, SEPTEMBER 17: NASA satellites may have missed more than 50% of the phytoplankton in the Southern Ocean, making it far more difficult to estimate the carbon capture potential of this vast …
