The climate crisis is a health crisis
We mobilise the global health community to accelerate climate action
We are doctors, nurses, clinicians, and therapists. We are health advocates, researchers, public health and policy experts.
We have come together because, wherever we are in the world, we are seeing how the climate crisis is impacting our patients, our communities, our public health and healthcare systems. Respiratory diseases are escalating; communicable diseases are spreading; humanitarian disaster are becoming more frequent.
The climate crisis is a health crisis and our communities and healthcare systems are starting to buckle.
But there is an answer: Climate solutions can be health solutions. That’s why we’re working together to hold decision makers accountable. To protect human health, we have to restore the planet.
We have a unique opportunity to improve health for all and to tackle global inequality, if we act fast.
