I made panels of squares, 70 of them, each to represent almost 2 years starting from 1900 to 2020, and painted them as scientifically correct as I could from the data of Dr. Ed Dawkins from Reading University.

The tiles were made in moulds in plaster resin. They became the canvas. It was a very mindful process to paint the tiles, while at the same time alarming to see the extent of temperature increase.

Having such a big space I felt made the impact of temperature change have more impact. If I was doing it again, I would have started from 1800.
