Geoengineering, which involves large-scale technological interventions in the earth's climate system, may have unintended consequences, such as worsening climate extremes, if not coordinated globally. Some reports suggest that geoengineering could potentially help mitigate the effects of climate change in specific regions, like the amazon rainforest. However, its overall effectiveness and potential risks, including the possibility of triggering conflict, are still being assessed and debated.
