Why is the world warming up?

Zašto se Zemlja zagrijava?

Let's think of Earth for just a moment as a greenhouse.

Zamislimo na trenutak da je Zemlja staklenik.

Every second, a huge amount of energy smashes into our greenhouse.

Svake sekunde, ogromna količina energije zaleti se u naš staklenik.

Our atmosphere, the glass roof and walls,

Naša atmosfera, stakleni krov i zidovi,

reflects some of that energy,

odbijaju dio te energije,

but most of it passes right through and heats everything up.

ali većina prođe kroz staklo i zagrije sve unutra.

Much of that heat used to escape back into space,

Velik dio te topline korisi se za povratak u svemir

keeping us at a stable, warm temperature.

zadržavajući nas na stabilnoj, toploj temperaturi.

But then something changed.

Ali zatim se nešto promijenilo.

Humans began to spew enough carbon dioxide to fill billions of greenhouses each day.

Ljudi svakodnevno proizvedu dovoljno ugljikovog dioksida za milijarde staklenika.

What does all that greenhouse gas do?

Što radi sav taj staklenički plin?

It makes the glass of our greenhouse thicker.

Podebljava staklo našeg staklenika.

Thicker glass means heat escapes into space much more slowly.

Deblje staklo znači da toplina odlazi u svemir mnogo sporije.

And don't forget, energy from the sun

I ne zaboravite, energija iz sunca

is still streaming in just as quickly as before.

i dalje struji jednako brzo kao i prije.

The result is a planet with temperatures too hot for our liking

Rezultat toga je planet s temperaturama prevrućim za naš ukus

and, eventually...

i na kraju...

living.

život.
