Fresh from the weekend, this is CNN STUDENT NEWS and I'm Carl Azuz.
Happy to see you this Monday, December 7th.
First up, an act of terrorism.
That's how U.S. officials are treating last Wednesday's shootings at a conference center in San Bernardino, California.
Syed Rizwan Farook and his wife, Tashfeen Malik, killed 14 people at a holiday party.
They were both killed later Wednesday in a shootout with police.
On a day of the attacks, officials say Malik had pledged allegiance to the ISIS terrorist group.
Law enforcement authorities believe the attack might have been inspired by ISIS.
They're not sure if the militant Islamic group actually ordered or directed it.
U.S. President Barack Obama has been criticized for how he's handled the threat of ISIS and he's been accused of downplaying that threat for political reasons.
Last night, he delivered a rare public address from the Oval Office.
He's only done that two times before.
President Obama sought to reassure a nervous American public that he has a plan to defeat ISIS and protect the U.S. homeland.
Many Americans are asking whether we are confronted by a cancer that has no immediate cure.
Well, here's what I want you to know:
the threat from terrorism is real, but we will overcome it.
We will destroy ISIL and any other organization that tries to harm us.
Our success won't depend on tough talk or abandoning our values, or giving in to fear.That's what groups like ISIL are hoping for.
Instead, we will prevail by being strong and smart, resilient and relentless, and by drawing upon every aspect of American power.
Next today, a tentative deal was reached over the weekend at the United Nations Conference on Climate Change.
It's also known as the COP21 conference and it runs through this Friday in the French capital.
The draft agreement involved negotiators from 195 countries.
It aims to reduce carbon emissions or greenhouse gas emissions around the world.
But it doesn't say by how much countries should aim to reduce their carbon emissions by the year 2050 and it's not clear what the penalties would be for a country that doesn't keep its promise.
Negotiators would be working throughout the week to address and reach a final legally binding deal.
Most scientists say human activities have likely caused global temperatures to heat up over the past century.
Some critics say the science leaves room for doubt and that humans don't have a significant effect on climate change.
On September 1st, 1859, a massive storm hit causing problems worldwide.
But nobody felt it and without a telescope no one could see it.
It caused brilliant auroras far south of the Arctic.
It disrupted telegraph communications, reportedly setting fires in offices and shocking operators.
Scientists say it was a solar storm, the kind of thing that could have even greater effects now.
The White House released an action plan two months ago to coordinate with other countries and restore services in the U.S. in the event of bad weather in space.
Solar storms have been known to cause all kinds of trouble, disrupting flights and power grids, sounds kind of scary.
So, how worry should we actually be?
The Danger of Solar Storms.
The weather in the sun is a little different than the weather here on Earth.
It consists of solar wind, solar flares and coronal mass ejections, which are these giant bubbles of plasma and magnetic fields from the sun that send high speed particles into space.
These storms can last a few minutes or several hours.
And even though they're happening over 90 million miles away, they're so powerful that their effects can linger in our magnetosphere and atmosphere for days or weeks.
If directed at Earth, these flares and CMEs create geomagnetic storms that then dazzle us with spectacular auroras.
But that's the fun part.
Beyond the light show, these solar storms can harm most modern day technology like satellites, communication systems,power grids and airplanes.
They can make airplanes disappear from radar detection and cause major blackouts.
In 1989, a solar storm caused a blackout in Canada that left 6 million without power for 12 hours.
While our technologies are at the mercy of these solar storms, our bodies are not.
That's because the earth's atmosphere shields us from harmful radiation.
But astronauts who are traveling through space won't be as lucky.
Shielding astronauts from the space weather is something NASA is working on right now to make sure our astronauts are safe and shielded on future deep space missions.
But back here on earth, there's a facility in Boulder, Colorado, that monitors the sun's forecast.
It's called the Space Weather Prediction Center.
So, by getting ahead of the space weather, we can better protect our technology.
We always find our "Roll Call" schools at the previous day's transcript page.
So, this came from Friday's transcript at CNNStudentNews.com.
Bahia is a state in eastern Brazil.
It's where we found the Atha School for Boys. Great to see you.
From Las Vegas, the Chargers are charging in.
Clark High School is watching in Nevada.
And in the city of Angola, in northeastern Indiana, the Yellowjackets are here from Angola Middle School.
In August, we reported that former U.S. President Jimmy Carter had been diagnosed with cancer.
