Over 40 scientists have issued a statement warning against the push for agricultural methane 'temperature neutrality', arguing that alternative metrics like 'Global Warming Potential Star (GWP*)' are being misused to justify significantly weakened climate goals. The statement emphasizes that the concept of 'no additional warming' is being employed to lower ambition in climate targets, potentially undermining efforts to combat global warming.
Misuse of GWP*
The scientists highlight that GWP*, which calculates the warming impact of short-lived gases like methane differently from long-lived CO2, is being incorrectly applied. This approach, they argue, allows for continued high methane emissions under the guise of 'temperature neutrality', delaying necessary reductions.
Implications for Climate Action
The statement calls for robust, science-based targets that align with the Paris Agreement's goal of limiting warming to 1.5°C. The scientists urge policymakers to reject misleading metrics and adopt comprehensive strategies that address all greenhouse gases effectively.
