Mechanical teaching tool for understanding positive feedbacks in non-linear climate change.

Building widespread intuitive understanding of #AbruptClimateChange is key to achieving a successful grassroots response.

A small weight, "m1", added to one side represents warming forcings (e.g., excess #CO2).

Without feedbacks (valve between bottles closed), the weight causes a small tilt.

With positive feedbacks (valve open), the weight causes water to flow and a much larger tilt occurs.

The Earth has several known positive feedbacks (e.g., albedo, methane turnover, added water vapor).
