Why climate (in)action is a public health emergency - reflections from COP29.
Earlier this week I attended the global health day at COP29 in Baku - This year's climate summit again underscored the urgency of addressing the climate crisis. It’s clear we’re not moving quickly enough. Climate change is a health crisis as much as it is an environmental one. It is worsening inequalities and disproportionately impacting the most vulnerable. Health and the effects that climate change have on people's health can no longer be separated or ignored.
Key themes from this year's discussions align closely with global health priorities. Here are three takeaways:
1.???Securing sustainable financing: At the signing of the Baku COP Presidency’s Continuity Coalition for Climate and Health today, governments, international organizations, financial institutions and civil society explored pathways for scaling up financing and operationalizing the COP28 Guiding Principles for Financing Climate and Health Solutions. The discussions covered financing needs, opportunities, gaps, and the development of an ambitious roadmap for climate and health finance.
While every nation has a role to play, wealthier countries must step up by committing to ambitious climate finance goals—and delivering on them. Experts estimate we need $1 trillion annually to respond effectively, and the cost of inaction will only grow. We need to advocate for stronger and sustained financing goals and a commitment to meet them.
2.???Building climate-resilient health systems and investing in the workforce: Strengthening climate-resilient health systems is critical to ensuring care during extreme weather events and other disruptions. Investments in early warning systems, robust supply chains, and primary health care are essential to meeting these challenges. Equally important is training health care workers to respond to climate-driven health conditions, including new disease patterns, food and water insecurity, and mental health needs.
3.???Addressing shifting disease patterns and emerging threats: Climate change is driving the spread of diseases like malaria and dengue into new regions, posing significant challenges to health systems. These shifts require strengthened surveillance systems, early warning mechanisms, and data-driven responses. At the same time, climate change is exacerbating antimicrobial resistance (AMR), a major threat to global health.
Addressing these risks will require investments in research and cross-border collaboration to improve preparedness and response.
The urgency is undeniable, but so is the opportunity to drive meaningful change. Let’s work together to ensure climate finance reaches those who need it most, and to build a healthier, more equitable future for all.
