deAre you scared of climate change?
deA little bit. It's a complicated topic, and I don't really understand why it's happening.
deMe too. I've been reading a book about it, and the uncertainty is scary to me.
deCan you explain to me why the climate is changing?
deScientists think it's because of the greenhouse gases humans are producing.
deWhat are greenhouse gases?
deCarbon dioxide, water vapor, methane, and many others.
deAnd what produces greenhouse gases?
deMany things. Examples are: driving cars, coal power plants, or factory farming. They cause an enhanced greenhouse effect in the atmosphere.
deWhat is a greenhouse effect?
deIt's a natural process that warms the earth. The gases reflect the sun's energy and keep the planet warm.
deNow I understand. More gases mean that also more heat becomes trapped under them? Just like in an actual greenhouse.
deYes, you are correct. And that's why the climate is changing.
