  I don’t think there is a simple answer for this, if we stopped polluting the atmosphere today it may still take decades to start healing. Scientists are working on ways to reverse the changes, but there will not be a quick way to fix it. We all need to do our bit by reducing our own pollution, recycling, turning lights off and so on.
