How does Earth breathe CO2 under different #ClimateChange scenarios?
Have a look at this visualization showing seasonal variations of atmospheric CO2 modulated by anthropogenic emissions and the strength of the ocean and land carbon sinks.
Computed with an #EarthSystemModel #MPI-ESM.

1. Using the Earth system model MPI-ESM-1.2, we ran a large ensemble of CO2 emission-driven simulations enabling the interactive carbon cycle. In such simulations, CO2 emissions are prescribed and the atmospheric CO2 is computed prognostically. In this visualization, changes in the color indicate the simulated increase in atm. CO2 concentrations due to rising emissions for the historical past (1960-2014) and for the four Shared Socio-economic Pathways scenarios SSP126, SSP245, SSP370 and SSP585 (2015-2100). The surface atm. CO2 concentration is shown with color and its relative seasonal variation with height.

  Seasonal variations of atmospheric CO2 concentration under climate change
  
  In order to understand how the climate change induced by different CO2 emission scenarios affects carbon-climate feedbacks and the resulting atmospheric CO2 concentration growth, we extended the simulations that have been carried out within the 6th Coupled Model Intercomparison Project (CMIP6).
