I'm pleased to say the images for Nitrogen 21 are now documented: check this site under solo interventions. I've also updated the text from ArtCOP21's event announcement; it can be found among Writings as Intervention: Nitrogen 21.
Many other exciting international art projects/events/extravaganzas are featured by ArtCOP21 until the end of December. Truly "a global festival of cultural activity!" So, there's still time to create your own project/statement - and add to the momentum for the necessity of conscious climate change.
