Ice is melting worldwide and the rise in the sea level has increased faster than people can imagine over the last century.
전세계적으로얼음이녹고있고해수면의상승은지난세기에걸쳐사람들이상상할수있는것보다더빨리증가했다.
Recently, floods and droughts are becoming more common.
최근, 홍수와가뭄이점점흔해지고있다.
What is happening to our planet?
우리행성에무슨일이일어나고있는가?
As we already know, the phenomena are mostly caused by human activity, primarily the burning of fossil fuels that add carbon dioxide(CO2) and other greenhouse gases into the atmosphere.
Scientists say that to avoid these dramatic changes in the climate, the world must cut greenhouse gas emissions by up to 80 percent by 2050, and eliminate them entirely by the end of the century.
In 2015, the world emitted 36 billion tons of carbon dioxide to produce energy.
2015년개정세계는에너지생산을위해360억톤의이산화탄소를배출했다.
How can we reduce a number like 36 billion tones to zero?
어떻게360억톤의숫자를0으로줄일수있을까?
Whenever I am faced with a problem, I turn to my favorite subject: math.
문제에직면할때마다, 나는내가가장좋아하는과목인수학에의지한다.
What I needed was an equation that would help me understand how we ould get our CO2 gas emissions down to zero.
제게필요한것은이산화탄소배출량을0으로줄이는방법을이해하는데도움이되는방정식이었습니다.
Here's what I came up with.
이게내가생각해낸것이다.
It might look complicated, but it's not.
복잡해보일수도있지만그렇지않다.
On the right side is the total amount of CO2 we put in the atmosphere.
오른쪽에있는것은대기중에총이산화탄소의양이다.
This is what we need to get to zero.
이것이우리가0에도달하는데필요한것이다.
It's based on the four factors multiplied on the left side of the equation:
이값은방정식의왼쪽에곱한네가지요인에기초한다.
the world's population(P); the services used by each person(S); the energy needed to provide each of those services(E); and finally, the carbon dioxide produced by that energy(C).
Solar and wind power are reliable energy sources so long as the sun is shining and the wind is blowing, but people still need more dependable energy on cloudy days, at night, and when the air is still.
When I say "miracle," I don't mean something that's impossible.
내가"기적"이라고말할때, 불가능한것을의미하는것은아니다.
We've seen miracles happen before.
우리는전에기적이일어나는것을본적이있다.
The personal computer, the Internet, the polio vaccine.
개인용컴퓨터, 인터넷, 소아마비백신.
None of them happened by chance.
그들중누구도우연히일어나지않았다.
They are the result of research and innovation.
그것들은연구와혁신의결과물이다.
However, when it comes to the problem of climate change, time is not on our side.
그러나기후변화문제에관해서라면시간은우리편이아니다.
Every day we are releasing more and more CO2 into the atmosphere and making the problem worse.
매일우리는점점더많은이산화탄소를대기로방출하고문제를악화시키고있다.
We need a massive amount of research into thousands of new ideas, even ones that might sound a little crazy, if we want to get to zero emissions by the end of this century.
