Hello everybody.
Now today is Monday, September 21st.
Let's get to your news.
We begin in South Africa where officials are trying to address a problem at the intersection of public safety and nature conservation.
Troops of baboons are roaming neighborhoods in Cape Town, damaging property and causing residents to fear for their safety.
CNN's Larry Mado explains a controversial plan to address the problem.
Cape Town residents are taking notice of a growing controversy over baboons and what to do about them.
Troops of baboons are roaming the streets, raiding homes, and riing up residents.
These Chakma baboons are Southern Africa's largest monkey species.
And as the city expands, conflict between baboons and residents has grown.
And now the city has a plan to solve their primate problem.
Permanently cage around 60 of the animals as an alternative to culling.
>> And that we're left with two very difficult decisions.
We could either callull the troops, which is arguably the ecological solution, or we could um find a space that we could set up an urban wildlife center and allow those animals in those troops to live out their lives in a higher standard of care with a quality of environment.
But that plan has sparked an outcry and fierce debate.
Should baboons that have adapted to city life be confined or should people find a way to coexist with them?
Suan Norton says she regularly feeds fruit to baboons that visit her home.
>> They're not dangerous.
Um they are they treat you as you treat them.
If you treat them with anger and force, they come back at you with force.
If you treat them like a pet, like a cat or a dog, like I treat them, then we live together in the, you know, in harmony.
City officials say the baboons will be better off if they're confined.
>> These are not wild baboons anymore.
They live in an urban area and what they are getting, whether we agree or disagree, they are going to live their lives better for 30 years.
>> Animal welfare groups say the root of the problem isn't the baboons, it's urban encroachment.
They argue residents need to do more to secure their homes, protect trash, and eliminate easy access to food.
>> If you are living in an area where there is wildlife, then you need to live and coexist with the wildlife.
>> With residents now taking to the streets in protest, the battle over Cape Town's baboons comes down to one question.
Can people and wildlife learn to share the city, or will one have to make way for the other?
Activists in Catmandeue, Nepal, held a silent protest and candle vigil over the weekend, demanding more action from the world on climate change.
The nation is still reeling from a collapse of a glacier in late August that triggered catastrophic flooding.
It killed more than,300 people and left thousands missing.
Activists honored those victims during the event.
One demonstrator talked about the reason he decided to participate.
This is not a protest.
We are silently just making all the crowd all the public to recognize the climate change and how it is affecting the Nepal despite its contribution is very low like Nepal is contributing 0.027% 1027% in the carbon emission global carbon emission and we are getting all the you know climate related hazards and we are the youth are here to show the solid solidarity to the people who lost their life in the Russa Bikosi flood.
>> Time for 10-second trivia.
The first T-Rex fossil was discovered in which US state?
Montana, Wyoming, South Dakota, or New Mexico.
If you said Montana, put your hands up.
The first T-Rex fossil was discovered in 1902 in Montana.
In 1905, the dinosaur was officially named Tyrannosaurus Rex, meaning tyrant lizard king.
For decades, scientists have debated whether the T-Rex was more like a coldblooded lizard or a warm-blooded bird.
Now, they may finally have their answer.
Researchers at the University of California studied the chemical makeup of three fossilized T-Rex teeth and found that the dinosaur had a body temperature of about 97° F, surprisingly close to ours.
That warmer body temperature suggests T-Rex could generate and maintain its own body heat.
And that could help explain how this massive predator was able to live across a huge range of climates, including places as far north as what is now Alaska.
So, while T-Rex disappeared about 66 million years ago, scientists are still finding new clues about how it lived.
Tomorrow marks the auto atominal equinox in the northern hemisphere and many of us may be noticing that mother nature is starting to show off.
Fall foliage colors are popping with trees starting to turn brilliant shades of yellow, red, and orange.
But have you ever wondered why and how we get this colorful show each and every year?
Coy and I took a walk outside to discuss the science behind this dazzling display.
Fall foliage colors are popping with trees starting to turn brilliant shades of yellow, red, and orange.
Have you ever wondered why and how the leaves change colors?
Who better to ask than our CNN meteorologist, our weather wizard, Allison Chinchar.
So great to see you looking today with your display.
Speaking of display, how do these leaves change color?
Why do they change color?
And how do they know when to start?
>> Right?
Because sometimes they change a little bit later in the year versus others.
So yeah, there's a lot of factors here, Koi, but the biggest one is daylight hours.
As the days start to get shorter and we have less and less daylight as we head into winter, it's essentially kind of a cue to them to stop photosynthesizing.
Now photosynthesis is basically using the sunlight to give them food and energy.
But this process slows incredibly in the winter months.
So the trees aren't dying, they're just going dormant.
>> Why do some leaves turn red like this one?
>> Right?
So, not all trees have the special gift that allows them to be this beautiful color.
Basically, what they have inside of them is something called anthocyanin.
And it allows these trees when they start to go through that photosynthesis process in the winter when they slow down, they're changing into this beautiful red or sometimes even that pretty purple color.
All because they have this special ingredient.
But you also have to have the right weather conditions.
You have to make sure you've had enough water leading up to the fall season and also plenty of sunlight.
>> Now, why is it that some trees don't change colors and nothing falls, >> right?
So, these are what we refer to as evergreen, hence the color trees.
Basically, these trees have evolved so that they never stop going through the photosynthesis process.
Now, it slows considerably in the winter, but it never actually stops, meaning they don't have to lose their leaves or change their color.
in this warming climate environment that we're living in and we're experiencing nowadays.
How might warming temperatures around the world affect the changing colors of the leaves?
>> Right?
So, the most obvious answer to that is the leaves will be falling off much later into the season because we're staying warmer longer.
If trees could actually pick their ideal conditions, it would be for the temperatures to cool down gradually like you and I would probably pick.
But if temperatures drop too quick, let's say 30 to 50° in just a couple of days, trees can go through what's called shock, which causes them to just drop their leaves, even if they never ended up fully changing colors.
>> So, why do trees decide to let their leaves go?
Is this like a preservation thing?
That's something they have to do.
>> It's to really save a lot of the energy that the tree would use up during the winter.
Many people don't know this, but leaves take up the vast majority of the water source that a tree takes in.
So, if it doesn't have its leaves anymore, it can consolidate a lot of that energy to get through a rough winter.
>> Thank you for helping us branch out today and get to the root of uh this very interesting topic.
>> Today's story getting a 10 out of 10.
A Minneapolis training program that aims to help more women become firefighters.
>> We want to push the women to not just reach the bar.
We want them to crush glass ceilings.
We want them to show up and be undeniable that they deserve to be there because we do.
>> According to the National Fire Protection Association, only 9% of the nation's firefighters are women.
And the trainers in this program are trying to fight the stigma that women can't meet the physical demands.
>> When they call 911, they're calling you on their worst day, and they need you to come and save them, and you have to be physically ready for that.
that firefighting is an extremely physical job and we must be prepared for that.
You're literally doing this to save a life.
You being in shape and physically prepared can determine if someone lives or dies.
>> One workout at a time, those women are proving that the desire to help people is one of the most heroic actions of all.
All right, superstars.
I've got time for one shout out today.
This goes to Miss Little at the Bonire Juvenile Correctional Center in Bonire, Virginia.
Thank you so much for subscribing to our YouTube channel and keep up the good work.
I hope you all have a fantastic day.
