The discussion centers on the challenges facing carbon dioxide removal (CDR) technologies and the carbon credit market. The key issue highlighted is that current markets predominantly address emissions reductions rather than the large, existing pool of atmospheric CO2, which poses a long-term climate and ocean chemistry challenge. The concern is that traditional carbon credits are inadequate for managing the substantial legacy CO2 already in the atmosphere, which will affect climate long after emissions reach zero. This issue is exacerbated by the lack of acknowledgment from entities like the IPCC of the need for dedicated CDR efforts.

The current market for carbon credits and emissions reductions is seen as failing to address this problem effectively. The absence of endorsement from the Science Based Targets initiative (SBTi) is believed to be a major setback for the growth of traditional carbon credits. The SBTi's failure to differentiate between removals and offsets is critic

Dear Colleagues, Attached is a 7 page excerpt (not including title page and references) on Direct Climate Cooling coordination and governance from the HPAC Cooling paper that I thought might be useful for upcoming discussions on this topic. Best, Ron -- Healthy Planet Action Coalition Addressing the Urgent Need for Direct Climate Cooling: Rationale and Options An Open Letter to the IMO Supporting Maritime Transport that Cools the Atmosphere While Preserving Air Quality Benefits --

The discussion delves into the complexities of climate science, particularly focusing on the potential effectiveness and timeframe of a proposed atmospheric methane removal strategy known as GRAP (Global Reduction of Atmospheric Pollutants). The exchange involves multiple experts including Robert, Oswald Petersen, Thomas J. F. Goreau, and Mike, each offering insights and perspectives on various aspects of climate modeling, atmospheric physics, and geoengineering.

Robert initially raises questions about the timing and efficacy of GRAP, particularly in relation to the timeframe for surface temperature impacts following methane reduction. He acknowledges the inherent complexity of the climate system but seeks a simplified understanding to assess GRAP's potential contribution to mitigating climate change.

Oswald provides details about the proposed GRAP method, emphasizing its potential effectiveness and cost. He highlights the need for accurate atmospheric modeling to determi
