The author of the recently published book "The Uninhabitable Earth: Life After Warming", David Wallace-Wells (David Wallace-Wells), warns that "there is not much time left to prevent the end of the world". The author is convinced that humanity must reduce production by 30% over the next 30 years, or face an inevitable catastrophe. In his message, Wallace-Wells states: "Projections suggest that if the trajectory of global warming is not altered, global GDP will decrease by 30% compared to a scenario without the impact of climate change".
