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.
RT Paul Beckwith (https://t.co/Cz8p1g788A):
Positive Feedback in Climate: Stabilization or Runaway, Illustrated by a Simple Experiment https://journals.ametsoc.org/doi/10.1175/BAMS-D-14-00022.1 #ClimateAction #climate #ClimateChange #GlobalWarming #weather
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).
