Scientist sealed in airtight biodome aborts experiment early due to CO2 levels

Despite his three-day attempt falling short, Kurtis Baute says the message about climate change remains the same.

A scientist who set out to spend three days sealed inside an airtight biodome to raise awareness of climate change has aborted the experiment 15 hours in, after CO2 levels became too high.

Canadian Kurtis Baute, 28, was living with around 200 plants inside the greenhouse to clean his air and provide oxygen – but a cloudy day in British Columbia limited photosynthesis, allowing CO2 levels in the chamber to rise.
