Motivating the Masses is the first instalment of Charlie and James's discussion about the factors that influence and affect climate negotiations. In the lead up to COP21/Paris 2015, it is becoming increasingly apparent that failure to negotiate a treaty that stops dangerous climate change is not an option. In the wake of Mark Hurlstone's keynote at WSEN2015, James and Charlie cover the impact of trust and uncertainty on cooperation and include a social experiment they conducted themselves to prove the influence trust has on cooperation.
