Knowledge about adaptation has significantly expanded since AR5 . While understanding regarding the extent of adaptation gaps remains limited, the available evidence suggests significant adaptation gaps exist . Many current adaptation efforts constitute adaptation planning, rather than implementation . Most current implementation efforts represent incremental as opposed to transformational adaptation despite the proximity to adaptation limits . Some current adaptation efforts are considered maladaptive because they increase some climate-related risks even if they reduce others . Gaps exist in key enablers of adaptation, such as finance . Given the long time scales involved with many adaptation actions and the potential to significantly reduce longer-term costs with near- term actions, closing many adaptation gaps requires actions over the next few years by governments, business, civil society and individuals at a scale and speed significantly faster than that represented by current trends.
