Live Environmental Monitoring



All graphs have been developed at UNEP/GRID-Geneva.

Temperatures

10 hottest years

This interactive graph displays the 10 hottest years in record, based on four different sources (NOAA, NASA, UK-MetOffice, JMA). It shows clearly that the 10 hottest year every recorded (since measurements started in 1880) all occur in the last 17 years. This graph is updated manually once a year.

 

Global surface temperature

This interactive graph, is based on four independent sources (NOAA, NASA, UK-MetOffice, JMA). It shows the trend of the global surface temperatures, which is clearly upward. Fluctuations are a normal phenomena, but a general warming trend is obvious. This graph is updated manually once a year.




Average World Monthly Temperature

This interactive graph displays the seasonal and non-seasonal global monthly average temperature anomalies compared to the 1980-2015 annual means.

 

Global Land and Ocean Temperature Anomalies

This interactive graph shows the change in global surface temperatures relative to 1910-2000 average temperatures.

     
 

Carbon Dioxide (CO2)

Carbon Dioxide (CO2) concentration

This interactive graph displays the monthly and annual mean carbon dioxide concentrations globally averaged over marine surface sites since 1960.

   
 

Sea Ice Extent

Arctic Sea ice extent live


This interactive graph displays values of the Arctic sea ice extent. It is automatically updated every day and shows a severe decline in the Arctic sea ice extent since the beginning of satellite measurements in 1979.

 

Arctic Sea ice extent mean

This interactive graph is regularly updated and displays the deviations from the minimal and maximal values of the Arctic sea ice extent since 1978, compared to the average 1980-1999. The deviation to the minimal sea ice extent is particularly noteworthy.

 

 

Arctic Sea ice extent daily difference with 30 years average


This interactive graph displays the daily difference between Arctic sea ice extent compared to a 30 years mean. It is automatically updated every day.

 

 

 

Antarctic Sea ice extent live


This interactive graph displays values of the Antarctic sea ice extent. It is automatically updated every day.

 

Antarctic Sea ice extent mean

This interactive graph is regularly updated and displays the deviations from the minimal and maximal values of the Antarctic sea ice extent since 1978, compared to the average 1980-1999.

 

 

 

Land glaciers mass

Change in glacier mass


This interactive graph displays values of the annual as well as cumulative annual mass balances of 'reference' glaciers since 1957 based on a live data stream from the World Glacier Monitoring Service (WGMS).

 


 

Stratospheric ozone

Antarctic

Antarctic Stratospheric Ozone

This interactive graph shows the Antarctic Ozone hole maximum and minimum density.


  Antarctic Minimum Ozone Concentration

This interactive graph shows the live Antarctic minimum ozone concentration.


Antarctic Ozone Hole Area

This interactive graph shows the Antarctic ozone hole area evolution.

 
 

LIMES


LIMES stands for "Live Monitoring of Earth Surface". It is a web application developed by GRID-Geneva, that allows to automatically monitor landcover changes using satellite imagery. LIMES will allow to follow several hundreds of sites per year.
