The power of large groups to influence society is typically impressive: whether in music, sports, protests, or celebrations, crowds often amplify impact. Have you ever participated in a “critical mass” bicycle parade when thousands of bikers flock to the streets, singing and dinging? You know what we are talking about; crowds can be very powerful. 

However, in the climate movement, this dynamic paradoxically works in reverse. While everyone in this diverse global coalition agrees on the urgency of climate action, the sheer diversity of viewpoints on the best strategies splinters the movement’s unity and can dilute its effectiveness. As a result, unified calls for action deteriorate into ideological debates. The “climate crowd” gets larger and larger, but it appears that, hampered by ongoing infighting, the growth of the crowd makes it less and less powerful.

How can we bridge gaps? How can we reduce the notorious infighting within the sustainability community?
