PS. The UN is not the source to consult, with all due respect.

We have to acknowledge that the UN plays a role and that the ECV are the product of a global consensus by meteorological scientists.

The 50 GCOS Essential Climate Variables (ECVs) (2010) are required to support the work of the UNFCCC and the IPCC. All ECVs are technically and economically feasible for systematic observation. It is these variables for which international exchange is required for both current and historical observations. Additional variables required for research purposes are not included in this table. It is emphasized that the ordering within the table is simply for convenience and is not an indicator of relative priority.
