It wasn't just in Paris.
People from around the world began celebrating on Saturday evening as officials from more than 190 countries agreed to a landmark global deal to address climate change.
And they had reason to celebrate. The Paris Agreement is a big step forward. It commits 196 countries to begin working together in an effort to limit global warming to no more than 2 degrees Celsius over pre-industrial levels. There's even a "stretch goal" of 1.5 C.
