Urgent Action Required: How Climate Change is Threatening Our Health

Climate change is not just an environmental issue; it’s a serious threat to our health. While many know this, the impacts often get overshadowed. A 2017 report from the Royal Society of New Zealand illustrated the health challenges linked to climate change. Since then, the urgency to respond has only intensified.

The most visible effects of climate change, like injuries and fatalities from extreme weather events, are on the rise. Research shows that around 37% of excess deaths during heatwaves are connected to climate change. In recent decades, we’ve seen a troubling increase in heatwaves, droughts, and floods, each leading to significant loss of life and livelihood.

Droughts can spark destructive wildfires, which in turn can cause millions of deaths due to air pollution. Floods can wipe out homes and create health risks through waterborne diseases. Furthermore, severe storms are becoming more frequent and damaging, leaving communities struggling long after the rain has stopped.

Climate change also indirectly impacts our health. Water scarcity and crop failures can lead to malnutrition, making people more susceptible to illness. Diseases once confined to certain areas, like dengue fever, are now spreading to regions that were previously safe.

Moreover, the rise in sea levels is displacing entire communities, particularly in vulnerable areas like the Pacific Islands. As climate refugees emerge, there’s increased stress on both the displaced and the nations receiving them, further straining health systems.

Mental health issues are also on the rise. The stress of watching these changes unfold can lead to what’s termed “eco-anxiety.” Many feel a sense of helplessness when they see leaders aware of climate risks yet failing to act meaningfully.

If we don’t reduce greenhouse gas emissions, the situation will worsen. Many areas could become uninhabitable, leading to unprecedented displacement. However, acting to combat climate change could also improve public health, such as reducing urban air pollution.

The current policies in many places, including Aotearoa New Zealand, fall short. The government’s approach shows a lack of urgency, often caving to industry pressures rather than implementing necessary changes. As highlighted by the Public Health Advisory Committee, solutions lie outside traditional healthcare. Community-led strategies could be key in resisting these industry interests.

In conclusion, acknowledging climate change as a public health crisis is critical. It’s not a problem we can solve merely through better healthcare. Integrated plans that address climate adaptation and mitigation with a focus on health are vital.

Experts emphasize the need for urgent action. According to climate scientist Prof. James Renwick, “We cannot afford to ignore the deep connections between climate and health.” The time for transformative action is now, not only for the planet but for our well-being.
