Daniel dances in the set of TVO Kids News holding a dog mug.

Daniel is in his twenties, with short curly brown hair and wears glasses, jeans, a purple T-shirt and an unbuttoned orange shirt.

Daniel says WELCOME BACK TO
TVOK NEWS.
I'M YOUR NEWS ANCHOR,
DANIEL,
AND IT'S TIME FOR OUR
FEATURED STORY OF THE WEEK.
NOW, A LOT OF YOU
HAVE HEARD
THE WORDS "CLIMATE CHANGE."
BEING TOSSED AROUND,
BUT DO YOU KNOW
WHAT IT ACTUALLY MEANS?
WE HAVE ENVIRONMENTAL ACTIVIST
DAVID SUZUKI
TO HELP US
FIGURE IT OUT.

A clip rolls on a screen behind them.

David is in his sixties, with short wavy white hair and a goatee. He wears glasses and an off white shirt.

David says HI, I'M DAVID SUZUKI.
PEOPLE ARE ASKING ME
ABOUT CLIMATE CHANGE
ALL THE TIME.
"WHAT IS IT?
HOW DOES IT HAPPEN?"
WELL, IT TURNS OUT
THAT IN THE ATMOSPHERE,
THERE ARE MOLECULES
LIKE WATER VAPOUR.
THERE'S CARBON DIOXIDE,
THERE ARE NITROGEN COMPOUNDS.
AND THESE ACT BY ALLOWING LIGHT
TO COME IN FROM THE SUN.
BUT WHEN THAT LIGHT
IS REFLECTED BACK UP,
THE HEAT, THE INFRARED,
IS TRAPPED OR REFLECTED
BACK DOWN ONTO THE EARTH.

An animation shows the process of evaporation.

David says THIS IS CALLED
THE GREENHOUSE EFFECT
BECAUSE THEY'RE ACTING LIKE
A GREENHOUSE.
NOW, ON MARS WHERE THERE'S
VERY LITTLE ATMOSPHERE
THERE'S NOTHING TO TRAP
THE HEAT.
SO IN THE DAYTIME,
YOU BOIL.
AT NIGHT, YOU FREEZE.
ON VENUS, WHICH IS COVERED WITH
WATER VAPOUR ALL THE TIME,
THE TEMPERATURE ON THE SURFACE
OF THE PLANET IS 400 DEGREES.
YOU CAN MELT LEAD
ON VENUS.
BUT EARTH IS JUST PERFECT.
WE'VE GOT THE RIGHT MIX OF
WATER AND CARBON DIOXIDE,
AND OTHER THINGS
THAT JUST KEEP THE TEMPERATURE
PERFECT,
NICE AND TOASTY,
FOR LIFE TO OCCUR.
BUT WHEN WE CAME ALONG
WE STARTED BURNING
A LOT OF STUFF
AND MAKING MORE AND MORE
CARBON DIOXIDE.
WE STARTED PUTTING NEW MOLECULES
LIKE CFCS INTO THE ATMOSPHERE
AND THOSE ALL TRAPPED
MORE AND MORE HEAT.

An animation shows how human emissions add carbon dioxide to the atmosphere.

David says SO THE RESULT IS THAT
BECAUSE OF HUMAN ACTIVITY
WE'RE NOW CAUSING
MORE HEAT TO BE TRAPPED
AND WE HAVE GLOBAL WARMING
WHICH AFFECTS CLIMATE
AND CLIMATE IS CHANGING.
FOR ANYONE WHO'S NOTICED,
LOT OF FOREST FIRES IN CANADA.
A LOT OF HURRICANES
NOW HAPPENING IN THE CARIBBEAN.
WHAT'S GOING ON?
COULD THESE BE RELATED TO WHAT'S
GOING ON WITH CLIMATE CHANGE?
I'M AFRAID THEY ARE.

Daniel says SO, IN OTHER WORDS,
JUST ONE PERSON
CAN'T FIX CLIMATE CHANGE.
BUT IF WE WORK TOGETHER IN
REDUCING OUR CARBON FOOTPRINTS,
SUCH AS TAKING PUBLIC TRANSIT
OR CARPOOLING,
OR MAYBE EVEN BIKING,
WE JUST MIGHT BE ABLE TO REDUCE
THE EFFECTS OF CLIMATE CHANGE.
THANKS FOR JOINING US
ON TVOK NEWS.
I'M YOUR HOST,
DANIEL.
AND THAT IS
WHAT'S HAPPENING.
