Context

U.N.'s World Meteorological Organisation has come up with a new Global Greenhouse Gas Monitoring Infrastructure to fill a key gap in the fight against ‘Climate change: standardised, real-time tracking of greenhouse gases.’

Background:

• Greenhouse gas concentrations in the atmosphere are at record high.
• 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 rise in CO2 from 2020 to 2021 was greater than the average growth rate over the previous ten years, and the largest year-over-year increase in methane since observations began.
• As part of the 2015 Paris Climate Accord, nations committed to keeping global warming "well below" two degrees Celsius (3.6 degrees Fahrenheit) over levels observed between 1850 and 1900, and 1.5C if feasible.
• Thus, the agreement's climate change mitigation measures required stronger scientific justification.

About Global Greenhouse Gas Monitoring Infrastructure

• It aims to provide better ways of measuring planet-warming pollution and help inform policy choices.
• The new platform from the WMO aims to reduce uncertainty over the final destination of greenhouse gas emissions by integrating space-based and surface-based sensing technologies.
• The data on how the planet's atmosphere is changing should become much more rapid and precise as a result.
