Time of Emergence of Climate Change Signals in the Puget Sound Basin

Full Title

Time of Emergence of Climate Change Signals in the Puget Sound Basin

Project Overview

The Time of Emergence (ToE) project aims to develop and implement a new approach to climate change decision support based on the concept of identifying the time at which the distinctive trend due to climate change is projected to emerge from the noise of natural climate variability. This concept, referred to as “time of emergence”, can help guide the prioritization and timing of climate change adaptation activities.

Through a combination of climate statistics, engagement with policy and management entities, and data delivery platform development, researchers aim to develop a new approach to climate change decision support based on the concept of ToE for the Puget Sound basin in the Pacific Northwest (PNW). Federal, state, and local decision-makers identified dozens of temperature-, precipitation-, hydrologic-, and streamflow-related variables relevant to drought, energy, fish, floods, human health, infrastructure, streamflow, and water quality to be used for ToE computation. Additionally, a web-based interaction system enable users to visualize how the ToE of the climate change signal varies geographically for different climate change-related parameters across the Pacific Northwest domain.
