Risk Category	Score (0-100)	Description
Physical Risk:	${results.scores.physicalRisk.toFixed(1)}	Exposure to direct impacts of climate change (e.g., extreme weather, water scarcity).
Transition Risk:	${results.scores.transitionRisk.toFixed(1)}	Exposure to risks from transitioning to a low-carbon economy (e.g., policy, technology).
