Climate Change is a Health Emergency: One of the biggest threats to children’s health is destabilization of Earth’s climate. Our changing climate is already harming human health. Without serious action to prevent the worst impacts of climate change, children born today will see agricultural and seafood declines, worsening floods, droughts, and wildfires, sea level rise, and more disease spread by ticks, mosquitoes, and contaminated water. Climate change is a health emergency. We must act. Reducing greenhouse gas emissions slows global warming and benefits our children and future generations.
