This is Climate One, changing the conversation about energy, economy, and the environment.

We know that climate change is endangering our planet.

What might not be so obvious is that it's also endangering our health.

Heat waves, air pollution, infectious diseases, and our health depends on adequate food and water

supplies. Climate change threatens each of these areas, and that's why it's a big issue.

Warmer temperatures have given rise to mosquito populations, bringing diseases like Zika and

Dengue fever out of the tropics. For North Americans, we really don't let it sink in how the world is changing.

There are no borders or walls that can protect us from mosquito-borne illness and this type of disease.

The hidden health hazards of climate change.

Thank you. Up next on Climate One. As climate change threatens our planet, it's also endangering our health.

How can we protect ourselves?

Welcome to Climate One, hosted by Greg Dalton.

Climate change isn't just an environmental problem. It's also a health hazard. Air pollution and changing weather patterns give rise to heat-related illnesses, asthma, and allergic disorders.

Disasters like Superstorm Sandy and Hurricane Irma leave hospitals scrambling to save patients

without power and resources. According to the Centers for Disease Control, insect-borne

diseases have tripled in the United States in recent years, and warmer weather

is largely to blame. Later in the program, we'll hear how hospitals and the health care industry

are dealing with these climate-related challenges, and we'll hear from a triathlete who survived a case of

West Nile virus that isn't convinced about climate change. But first, Jonathan Pats is

director of the Global Health Institute at the University of Wisconsin-Madison. He spoke with Greg

Dalton about why he believes climate change is the major health crisis of our time. So when people
