Attribution Science and Climate Fingerprints

Our Attribution Science and Climate Fingerprints program uses statistical methods to quantify whether and to what extent human-caused climate change altered the likelihood of specific weather events.

Through attribution science, scientists are able to identify weather conditions that are becoming more common due to human-caused climate change, allowing the public to adapt, prepare for these conditions, and manage their impacts. It also emphasizes the urgent need to reduce carbon pollution in order to prevent climate-related impacts from growing worse.

Our team works with global partners to develop techniques that quantify climate fingerprints in daily weather and extreme events worldwide, and to communicate these linkages. Our goal is to inform people about the realities of climate change and to catalyze changes that reduce impacts in the near and long term. 

Climate Shift Index®

The Climate Shift Index (CSI), Climate Central’s daily temperature attribution system, applies the latest peer-reviewed methodology to map the influence of climate change on temperatures across the globe, every day. Learn more here.

Attributing daily ocean temperatures to anthropogenic climate change (May 2024)

Ocean temperatures are rising and hit record levels around the world in 2023. While trends are clear and likely strongly connected to human-caused climate change, the oceans also exhibit variability on the daily level, leading to local extremes such as marine heatwaves. We present an operational system to estimate the impact of human-caused climate change on daily sea surface temperatures anywhere in the ocean.
