Drastic change is needed to limit the increase in the global temperature caused by climate change. More than two-thirds of global greenhouse gas emissions come from how we live our lives. But the behaviours that drive these emissions tend to be deeply habitual and hard to shift - the way we heat our homes, what we eat and how we travel to work. And our behavioural good intentions all too often fail to translate into action. So our climate question this week is how we can be nudged, or even shoved, to change?
