Yes, indeed. But if you read a little bit lower you would see this:
Climate change is caused by factors such as biotic processes, variations in solar radiation received by Earth, plate tectonics, and volcanic eruptions. Certain human activities have been identified as primary causes of ongoing climate change, often referred to as global warming.
I don't think we're talking about the same thing here. What i'm talking about is anthropogenic climate A.K.A Global Warming, which is caused by human activity. So Climate Change has two definitions, the climate change you've mentioned and the anthropogenic climate which is caused by human activity such as burning fossil fuel. And yes worrying about won't help, but certainly acknowledging the problem and trying to fix it would help a lot.
I apologize if my post wasn't that clear, i'm still a noob when it comes to writing. But thanks for your comment, i appreciate it.
