The San Francisco-based The ClimateMusic Project will perform Climate — an original composition by Erik Ian Walker that tracks historical and projected variations in the climate system — at 7 p.m. on Nov. 13.

As part of the Sanibel-Captiva Conservation Foundation’s (SCCF) Evenings at the Homestead series, the performance and synced animation use music to tell the urgent story of climate change in a way that resonates, educates, and motivates.

“The music of Climate has a powerful impact; hearing and feeling it gives you an understanding of the issues from your core, in a way that looking at a chart simply does not achieve. It’s a must-listen,” says SCCF Adult Education Director Jenny Evans.

The ClimateMusic Project was created to connect people to climate science and action through the emotional power of music. Its premise is that music is familiar, accessible, and — for most people — much easier to relate to than articles or lectures about the climate crisis.

Its current portfolio features four compositions, each created in a different style of music, which have been performed internationally.

Climate was composed by identifying four key climate change indicators and assigning each a musical analog:

• Carbon dioxide concentration is reflected in the tempo of the composition
• Near Earth atmospheric temperature is represented by pitch
• Earth energy balance (the balance between incoming energy from the sun and outgoing heat from the Earth) changes are audible as distortion
• Ocean pH is represented by compositional form

Climate tells the story of climate change from 1800 to 2250, following two possible scenarios for the future. It predominantly tracks “business as usual,” in which we do little or nothing to rein in carbon emissions. The second scenario represents a more hopeful “2 degree” scenario under which society succeeds in reining in emissions during the first half of this century.

This is the first in this season’s Evenings at the Homestead series. The outdoor event will be held in the pavilion at the Bailey Homestead Preserve, 1300 Periwinkle Way on Sanibel.
