ALT Six of nine planetary boundaries are currently transgressed. The length of the wedges symbolizes what the current state of the corresponding process is, in relation to the distance from the planetary boundary (end of the green area) and the Holocene baseline (origin of the diagram). The color symbolizes the risks associated with each. For example, a wedge may be very long because the current state is already very far from the planetary boundary and the Holocene. But it may still not be purple, because that is not yet associated with very high risks in this particular case. In other cases already a "small" overshoot (short wedge) results in a big risk: Then the color further inside already changes to purple.
