We can see and measure climate changes around the world. Global temperature is warming,
weather patterns are changing, polar ice is melting, and sea level is rising.
Climate has changed throughout Earth's long history. But this time is different. Worldwide temperatures are rising higher and faster than anytime we know
of in the past. And this time, human activities are causing it.
Can we slow this global warming by changing the way we live? Yes, there is still time. But it will take everyone working together around the world.
