Tonight on PBS Newsweekend, as Haiti spirals deeper into chaos, what can be done about

the nation's security and humanitarian crisis?

Then how the toll of climate change is affecting some people's mental health.

I feel very anxious about the state of the climate and our future.

I believe that if we don't make necessary changes now, we will be changed in the future

in ways that we do not want and cannot control and will not be able to mitigate.

And we hear firsthand what it's been like to live through the blistering heat wave in Arizona.

Tonight, there's violence and unrest across the globe from the Middle East to Western Africa

to the Caribbean, which is where we begin.

In Haiti, the situation seems to be getting progressively worse.

Gangs control half the country's territory and most of the capital, Port-au-Prince.

Just this past week, an American nurse working for a Christian humanitarian group

and her daughter were reported kidnapped.

And the State Department has ordered non-emergency workers and the families of all U.S.

government employees to leave as soon as possible because they say it's just not safe.

But for many Haitians, leaving is not an option.

They had sought refuge in the courtyard of the U.S. Embassy in Port-au-Prince,

dozens of families fleeing the gangs that have overrun their neighborhoods.

We don't have anywhere to stay. The bandits kicked us out of our home.

They rape us even if we are old. Even the little ones, they raped them also.

I had to run to come here last night. I had a fever. I was trembling.

I never experienced anything like this. We are in misery.
