The term 'solutions' has various synonyms used across this and previous IPCC reports, including options, measures, actions and responses. All denote policies, technologies, processes, investments or other activities undertaken in reaction to or with the intent of addressing some aspect of climate change . The term 'solutions' has drawbacks, suggesting a finality, that is, the problem is solved. Solving climate change in this sense is not likely for the foreseeable future. In addition, the word 'solutions' sometimes denotes a narrow set of responses, such as 'technical solution', as opposed to more wide-ranging actions that might be involved in a transition to resilience. Nonetheless, AR6 highlights the term 'solutions' because, compared to these other terms, when acted upon or incorporated in policy, it denotes effectiveness and some degree of progress at achieving desired goals.
