Do you mean that you don't understand why climate change is a major problem? That's a genuine question: I guess it is fine, but respectfully I think you should look into it. Because where we are headed now looks pretty bad, both for the half of humanity that will have to migrate because it won't be possible to survive in the outdoor conditions and for the half of humanity that won't want the other half to come to their country.
Problems will not stop to appear while that is not solved. The whole system becomes fragile, and minor disturbances will become major ones.
