What's up, sunshine?

Let's rise up this Tuesday, October 6.

I'm Koi Wire.

Today is National Coaches Day.

Did you know one of my favorite coaches had a profound impact on my life?

The late great Bob Craig, wrestling and football coach at Cedarcliffe High School in Camp Hill, PA.

Coach had a poem on the back of his business cards that said, "You may fool the whole world down the pathway of years and get pats on the back as you pass, but your only reward will be heartache and tears if you cheated the man in the glass.

Be sure to give a shout out, fist bump, high five, or hug to your coach in your life today.

Let them know you appreciate them.

Now, let's get you your news.

The US Supreme Court is officially back in session, and its new 9-month term started with a big one, climate change.

The justices heard oral arguments involving a lawsuit brought by Boulder, Colorado, the city, against Exxon Mobile and Suncor Energy.

The city actually brought the lawsuit nearly a decade ago, arguing the companies contributed to climate change and misled the public about the effects of fossil fuels.

The oil giants deny any wrongdoing and argue Boulder is essentially trying to regulate greenhouse gas emissions through state law, something they say should fall under federal authority instead.

So, here's the big question before the Supreme Court.

Can Boulder's claims even proceed to a trial?

This goes far beyond Boulder, though.

The decision from the high court will no doubt impact dozens of similar lawsuits nationwide seeking billions of dollars in damages.

Justice Samuel Alo is not participating in this case.

That's what's called recusal when a judge or justice steps aside from considering a case.

Alto hasn't given a reason, but he later told Bloomberg News that he felt it was quote prudent to step away given his holdings in energy stocks.

Beyond this blockbuster, the justices this term are set to take up other important cases, including decisions on semi-automatic weapons, voter ID laws, and the president's immigration policies.

Now to Europe where people are taking a stance trying to create positive change in an environment that they believe needs to be better.

First in France where more than 400 schools remain fully or partially closed Monday following days of demonstrations led by students.

They say they are frustrated by overcrowded classrooms, teacher shortages, and school buildings they say are unsafe or falling apart.

Some teachers have joined the students in their calls for reform.

legitimate.

>> So, it is entirely legitimate and normal for them to have demands.

And the fact that things get out of hand, the fact that there's violence is not the fault of the students or the high school students.

It's too easy to level accusations or say that high school or university students are being manipulated.

It is in fact social realities that are causing things to spiral out of control.

Unfortunately, we would really like things to calm down.

>> While many of the protests have been peaceful, some became unsafe.

Authorities say schools and other property have been damaged and police officers have been attacked.

Rights groups and students, meanwhile, have accused police of using excessive force, including batons and tear gas to disperse crowds.

The French government disputes that characterization, saying police have intervened when demonstrations became violent.

Thousands of people have been arrested, many of them minors.

Student representatives met with France's education minister, but say they still haven't received the changes they are seeking.

So the challenge now, can students, teachers, and government leaders turn a volatile confrontation into an actual conversation?

Because improving schools requires more than making noise.

Eventually, people have to find solutions.

Meanwhile, neighboring Spain is facing a very different crisis.

Housing.

Think rents rising faster than many salaries, too few affordable homes, and some families struggling to stay in neighborhoods where they've lived for years.

And now it's triggering a national election.

Spanish Prime Minister Pedro Sanchez has called a snap election for November 29th, ending the current parliament's term more than six months early.

He announced the move just 3 days after the governing body rejected a package of emergency measures aimed at tackling the nation's housing affordability crisis.

>> You, the people of Spain, must decide what role you wish to play in it and also what role you want Spain to play in it.

In recent weeks, hundreds of thousands of Spaniards took to the streets to demand lower rents, an end to evictions, stronger tenant protections, and a ban on big investors buying up residential property.

Hundreds of demonstrators camped out in Madrid's Puerto del Soul to protest the eviction of an 87year-old woman who has become a symbol of the crisis.

Now, supporters and critics of the current government alike have an early chance to choose their country's future.

Pop quiz hot shot.

Where can you find the world's tallest sea cliffs?

Norway, Peru, Hawaii, or South Africa?

If you said Hawaii, you're the pineapple of my eye.

The Machai Sea Cliffs are the world's tallest rising, nearly 3,900 ft above the Pacific Ocean.

That's more than three times as tall as the Empire State Building.

One of Hawaii's most recognizable natural landmarks is suddenly gone, collapsed into the Pacific Ocean.

The Hle Sea Arch towered about 90 ft above the Pacific in Hawaii's volcanoes National Park.

For more than 500 years, waves carved away at cliffs created by ancient lava flows, eventually sculpting this enormous natural bridge.

Officials at Volcano's National Park say the structure was still standing when the doors closed to the park September 23rd for tropical storm Nolo.

But when they reopened a few days later, the arch was nowhere to be seen.

The National Park Service has said the historical arch always had a limited lifespan and that the absence will give way for other natural marvels to be formed.

So essentially, nature is still building just really slowly.

And from losing land to making some.

Would you ever walk on glass to help keep a beach sandy?

Hear me out.

A team in Miami Dade County has just developed an innovative strategy to use the glass bottles we toss out to battle another problem, coastal erosion, or the loss of sand in their beaches.

Their idea, crush discarded glass until it's tiny enough, smooth enough, and safe enough to behave like sand.

That's some glass half full thinking.

Take a look.

Crashing waves, king tides eating away at our South Florida beaches.

This group of scientists and volunteers think they may have a solution.

>> Miami Dade has a waste problem and an erosion problem.

>> Miami Dade County residents generate 5 million tons of garbage each year.

So do Broward County residents.

And in all those piles of trash, tons of recyclable glass bottles.

>> There's a lot of glass.

The opportunity is enormous.

The sustainable startup Glass for Life partnered with the Frost Science Museum and Compost for Life on a series of experiments.

>> We're using glass waste, but we are also using food waste.

The compost is food waste and half of our trash is food waste.

>> They ground up recycled glass bottles to make glass sand.

In the first phase of the experiment, they compared sand oats grown in regular sand, glass sand, and a mixture of the glass sand and compost.

>> Adding the compost, we had significantly higher survivorship of our plants.

Plants grew between 12 to 25 times greater than the plants that grew in the native sand.

>> Now, the real life test is underway on historic Virginia Key.

They are planting hundreds of sea oats and will measure the results in just three months.

If this glass can grow sea oats at a reasonable rate and it can actually serve as a replacement for regular sand.

>> And it could start with the glass bottles we all throw away.

>> Today's story getting a 10 out of 10.

It is on like Donkey Kong.

Gamers from all over the country flock to Vortex Arcade in Sherwood, Arkansas for the Kong Clash 16 tournament.

Players try to get the highest score possible before the end of the infamous final level 22 in the original Donkey Kong game.

The annual competition takes place on the first weekend of October, and it is bananas.

The arcade's owner pulls 26 OG Donkey Kong games out of storage, fires them up on the arcade floor.

There are beginner, intermediate, and pro level, so you don't need to have some barrel jumping wizardry to compete.

And yes, they're playing a game released way back in 1981.

All right, sunshine shout out time.

This first one goes to all of our friends at Silver Lake in Middletown, Delaware.

Miss Fileleti wants all of you to know that she sees the hard work you are doing and she is so very proud of you and we are too.

Thank you for letting us be a part of your day.

This next shout out goes to Mr.

Mo at the Gainesland School in Milwaukee, Wisconsin.

After teaching his students origami earlier this year, his seventh and eighth graders created this 11,210 piece portrait.

This is so creative and way to stack that paper, y'all.

These shout out requests are getting uh increasingly impressive and I love how this story is unfolding.

Tomorrow is your word Wednesday, so hit us up on the Instagram, CNN10 or Koiwire.
