Climate change

VisioTerra

VisioTerra staged data from the IPSL model as part of the 6th IPCC study (CMIP6).



Three variables are considered :
  • precipitation ( PR )
  • minimum nighttime temperatures ( TMIN ) 
  • maximum daytime temperatures ( TMAX ).

Two scenarios are illustrated :
  • SSP245  corresponding to average  socio-economic pathways  (SSP) and a radiative forcing  (RCP) of 4.5 W/m² moderate
  • SSP585  corresponding to an immoderate use of fossil fuels as is currently the case  

The graph shows the evolution of the variable by smoothing the annual values of the model over 31 years. The values are calculated on the area delimited in black only (spatial aggregation). The images show the evolution of the variable over the years.

Detection, classification and analysis of oil slicks observed by the ASAR radar instrument in WSM mode onboard Envisat between 2002 and 2012. Oil slicks are classified according to whether they are of natural origin (oil seepages) or anthropogenic (oil spills from platforms or deballasting of ships).
