Climate change and pollution pose a profound threat to our planet. The effects of both of these anthropogenic challenges can further be amplified or dampened by each other through feedback loops. In order to develop actionable solutions, it is therefore crucial to understand the individual causes and mechanisms of impact, as well as their interplay. I will provide an overview ofcurrently known effects and feedback loop examples on a global scale, before highlighting the limitations of our current knowledge based on recent studies and identifying some key areas in need of coordinated efforts to build a more sustainable and resilient future.
