Beatie Wolfe creates a stirring environmental art piece about human impact on the planet, built using 800,000 years of historic NASA data. “From Green to Red” (taken from the title of a song Wolfe wrote in 2006 after seeing ‘An Inconvenient Truth') tracks the impact of human behaviour on the planet, creating a stirring visualization of the CO2 concentration in the Earth’s atmosphere, and asks us the question is it too late to turn back?
