Now / Teta Real-Time Climate Portrait of Vanuatu

MediumSingle-screen installation, live data
DurationContinuous — no loop, no end
Year2025–ongoing

Now / Teta — the word "now" in Bislama, the creole language of Vanuatu — is a real-time immersive installation that renders the exact atmospheric conditions of Vanuatu as they exist at this precise moment, anywhere in the world the work is shown. The work exists in permanent flux: never the same twice, never recorded, always live.

A photorealistic coastal scene — ocean, sky, beach — is continuously updated with live meteorological data drawn directly from Vanuatu's coordinates. Wind speed determines wave height and chop. Cloud cover drives volumetric density. Precipitation darkens the atmosphere. The sun and moon are astronomically accurate for Vanuatu's latitude and longitude at the exact local time. Embedded within the rendering are two invisible numbers: the real-time atmospheric CO₂ concentration measured at Mauna Loa, Hawaii, and the live carbon intensity of the electrical grid powering the device showing the work. Together they subtly thicken the haze and roughen the sea.

Consistently ranked among the world's most climate-vulnerable nations despite contributing less than 0.1% of global emissions, Vanuatu faces existential threats from rising seas, intensifying cyclones, coral bleaching and coastal erosion. Now / Teta asks the viewer to witness that ocean — not as data or statistics, but as a living, breathing presence. The connection between the viewer's world and Vanuatu's sky is not metaphorical. It is computational and direct.

Installation Format
Single-screen or projection; standalone .exe; designed for unattended exhibition
  • Open-Meteo APIWind, cloud cover, precipitation, visibility, temperature at Vanuatu coordinates (−17.73°, 168.32°). Every 10 minutes. open-meteo.com
  • NOAA Global Monitoring LaboratoryAtmospheric CO₂ concentration (ppm), Mauna Loa Observatory, Hawaii. Hourly. gml.noaa.gov
  • Electricity Maps APIReal-time carbon intensity of the electrical grid powering the installation (gCO₂/kWh). Every 15 minutes. electricitymaps.com
  • Astronomical formulaeSun and moon position computed from date, time, and Vanuatu latitude/longitude. No external API required.
Exhibition Requirements The work runs as a self-contained Windows executable from USB. It requires a single display output and an internet connection for live data; it degrades gracefully to seasonal averages without connectivity. No interaction is required or invited. The work runs indefinitely.
