World Meteorological Congress approves GHG monitoring initiative
Context
The World Meteorological Congress has approved a new greenhouse gas (GHG) monitoring initiative in a landmark decision.
About the new initiative
- The initiative supports urgent action to reduce heat-trapping gases, which are fuelling temperature increases.
- The new global GHG watchwill fill critical information gaps and provide an integrated and operational framework.
- The framework will bring all space-based and surface-based observing systems, as well as modelling and data assimilation capabilities, under one roof.
- The monitoring infrastructure will build on and expand WMO’s long-standing activities in GHG monitoring, implemented as part of the global atmosphere watchand via its integrated global GHG information system.
|
Major Components The GHG watch will consist of four main components:
|
Need of the initiative
|
Greenhouse gas concentrations are at record levels — in fact higher than at any time over the last 800,000 years |
- Lack of support: Many of the existing international and national activities dealing with greenhouse gases are supported mainly by the research community.
- Lack of framework: At present, there is no comprehensive, timely international exchange of surface and space-based greenhouse gas observations or modelling products.
