Increased evidence of climate change hasn’t shifted the global debate on the topic, and manfy doubt its effects. According to climate change expert George Marshall, this is because we’re in denial. In Don’t Even Think About It, Marshall outlines how personal values, basic human evolution, and perceptions of threats have “wired our brains” to ignore the growing peril of this field. According to him, in order to open the dialogue around climate change — and get friends to believe in the science — creating a personal, emotional framework for the debate is essential. He’ll offer advice on how to do this, giving specific examples of what to say when faced with climate change skeptics, and why “getting caught up in the scientific discussion” is so detrimental. Marshall is the founder of the Climate Outreach and Information Network.
