Context: The U.N.'s World Meteorological Organisation has come up with a new Global Greenhouse Gas Monitoring Infrastructure that aims to provide better ways of measuring planet-warming pollution and help inform policy choices.



  • The three major greenhouses gases are carbon dioxide, methane and nitrous oxide. Of those, CO2 accounts for around 66% of the warming effect on the climate.
  • The increase in CO2 levels from 2020 to 2021 was higher than the average growth rate over the past decade, and methane saw the biggest year-on-year jump since measurements started.
  • The 2015 Paris Agreement on climate change saw countries agree to cap global warming at "well below" two degrees Celsius above levels measured between 1850 and 1900 – and 1.5C if possible.


  • The WMO said there needed to be stronger scientific underpinnings of climate change mitigation actions taken under the agreement.
  • There are still uncertainties, especially regarding the role in the carbon cycle of the ocean, the land biosphere and the permafrost areas.
  • We therefore need to undertake greenhouse gas monitoring within an integrated framework in order to be able to account for natural sources and sinks.


  • The WMO's new platform will integrate space-based and surface-based observing systems, and seek to clarify uncertainties about where greenhouse gas emissions end up
  • It should result in much faster and sharper data on how the planet's atmosphere is changing.

World Meteorological Organization (WMO):

  • It is an intergovernmental organization with a membership of 193 Member States and Territories.
  • It was established by the ratification of the WMO Convention in 1950.
  • WMO became the specialised agency of the United Nations for meteorology (weather and climate), operational hydrology and related geophysical sciences a year later.
  • The UN Economic and Social Council is the parent organization of WMO.
  • WMO is headquartered at Geneva.
  • WMO is dedicated to international cooperation and coordination on
    • the state and behaviour of the Earth’s atmosphere, its interaction with the land and oceans,
    • the weather and climate it produces, and
    • the resulting distribution of water resources.
  • It facilitates and promotes
    • the establishment of an integrated Earth System observation network to provide weather, climate and water-related data
    • the creation of standards for observation and monitoring
    • the provision of weather, climate and water-related services - to reduce disaster risks and contribute to climate change adaptation etc.
    • the coordination of research and training in meteorology and related fields
  • Major reports published by the WMO are - Status of World Climate; Greenhouse Gas Bulletin.
