From 'Knowing' to Accountability: How Science Is Used to Pin Down Climate Responsibility

The word “science” traces back to the Latin scire, meaning “to know” — a root it shares with “conscience,” the shared sense of right and wrong. That connection between knowledge and moral judgment is at the heart of today’s climate debates, where attribution science is increasingly being used to determine who is responsible for a warming planet.

Attribution studies analyze extreme weather events and temperature trends to estimate how much human activity contributed to them. Rather than treating climate change as an abstract global issue, these studies link specific emissions to specific harms, opening the door to legal and political accountability.

The growing use of such evidence raises difficult questions: Can science fairly assign blame, or does it merely inform broader ethical and legal judgments? As researchers refine their methods, the line between knowing and holding accountable continues to blur — and that tension is likely to shape climate policy for years to come.
