The climate emergency has escalated around the world in 2023 in unprecedented ways as multiple compounding disasters and their health impacts have increased exponentially. It is one of the greatest public health threats of our time. The consequences have included the destruction of livelihoods, increased hunger, human suffering, and death and have led to increasing inequities within and between countries. While the planet experiences floods, heat waves, crop failures, fires, water shortages and more, fossil fuel subsidies have risen to a record high. We urgently call for the implementation of the strategies proposed in the IPCC 2023 report.
