What are climate signals?

Climate signals are long-term trends and projections that carry the fingerprint of climate change. Examples of observed long-term trends linked to climate change include rising sea levels, increasing extreme precipitation, and warming sea surface temperatures. Model projections can identify conditions expected in a warming world such as an increasing frequency of intense hurricanes.

Climate Signals is a digital science platform for cataloging and mapping the impacts of climate change. Currently in open-beta release, the platform is designed to identify the chain of connections between greenhouse gas emissions and individual climate events.

Climate Signals consists of a curated relational database of events and their links to climate change, an event mapping engine, a searchable database of science reports, and a searchable gallery of climate change monitors relaying real-time data.

For each event in the database, an infographic engine provides a custom “signal tree” that illustrates the connections to climate change. The system of attribution used to link events to climate change is explained here. In addition, key resources are aggregated and curated for each event.

This open-beta release is offered for public user testing and engagement. Comments and feedback are invited and can be submitted here.

Greenhouse Gas Emissions

Heat trapping gasses, such as CO2 and methane, drive rising temperatures. Emission of CO2 also drives acidification of oceans.

Climate Event

Events are shaped by many factors. Increasingly climate change is a factor, particularly when climate change pushes systems past tipping points.
