While climate consciousness across the globe is on the rise, the fourth UN Environment Adaptation Gap Report has revealed a considerable gap between countries’ preparedness for climate change and the actual measures that should be put in place to prepare communities for a future of increasing climate risks. The research particularly underscores a growing divide between the estimated annual costs of adaptation and the actual global investments in resilience measures, drawing a distinct connection between our adaptation to climate change and sustainable development that results in healthy communities and thriving economies. Climate change will have a significant impact on human health over the next few decades, and while progress has been made in reducing climate-change related diseases and injuries, current adaptation efforts are by no means sufficient to minimize future health impact of a changing climate. The research highlights that unless adaptation efforts are strengthened considerably, heat and extreme event-related morbidity and mortality will continue to rise.
