The potential collapse of the AMOC—which could happen within this century, or be triggered within this century and play out over a longer timeframe—comes as a result of climate change caused by additional heat-trapping emissions like carbon dioxide in the atmosphere. But what exactly would cause the AMOC to collapse?

Last month, the National Academies of Sciences, Engineering, and Medicine (NASEM) released a report on a relatively new field of research – atmospheric methane removal. Addressing methane is critically important in addressing climate change – methane is the second largest contributor to human-driven warming after carbon dioxide.
