In order to monitor human induced greenhouse gas emissions and to coordinate their methods, for the first time we find that the space agency’s of more than 60 countries have agreed to engage their satellites, under the drive of Isro and the French Space Agency known as the CNES. According to a statement released by Isro Bengaluru on Friday, last year in December when the COP21 climate conference was held in Paris it acted as a wake up call. The space agency said that the historic agreement at the UN headquarters in New York on April 22, 2016 would not have been signed, as in the absence of satellites no one would have realized and recognized the reality of global warming.
Isro said, today 50 essential climate variables are being monitored out of which 26 are regarding rising sea level, sea ice extent and greenhouse gas concentrations in all layers of the atmosphere. All these can be measured only from space. Only satellites can verify whether all nations are fulfilling their commitment of curbing green house gas emission, and if this is done then only the Paris Agreement will be effectively implemented.
On April 3, the world’s space agencies were invited to New Delhi by Isro and CNES. Isro said that it was in this event that they decided to establish an independent, international system, by which they wanted to centralize data from their Earth-observing satellites through the New Delhi Declaration that officially came into effect on May 16. It also said that the goal now will be to inter calibrate these satellite data so that they can be combined and compared over time. In other words, it is to make the transition to closely coordinate and easily accessible by big space data.
