How have climate disasters been affecting human health?

Discover global impacts amidst severe weather events.

The impact of an influx of extreme weather events such as flash floods, hurricanes, heat waves and wildfires is affecting the health of the world’s citizens. 

“We’re seeing extreme weather — both heat waves and extreme winter storms — and ramped-up hurricanes that produce much more rain over longer periods of time, as well as worsening droughts, and all the health consequences of people driven from their homes,” Jeni Miller, the executive director of The Global Climate & Health Alliance, told Devex.

Extreme heat, for example, can cause tropical infections, pregnancy complications, mosquito-related illnesses and more.

“We found 58 percent of infectious diseases confronted by humanity worldwide have been at some point aggravated by climatic hazards,” reads a related study by the University of Hawai’i at Mānoa, which also shows human diseases have grown by nearly 60 percent due to increasing greenhouse emissions.

At Children Believe, we’ve seen the effects of climate change in the countries we work. We conduct assessments to address the needs children, families and communities have to help provide better emergency response and resilience.
