Questions of a Scientific Sort

I would now like to ask for some answers to some very important questions in the scientific realm. Is the sun losing power? If it is losing power; at what rate is the sun losing power? Is the earth's rate of rotation slowing down? If it is slowing; at what rate? Is the moon moving further away from the earth? If it is moving further away; at what rate? Is the ocean getting saltier every year? If it is getting saltier; at what rate? I believe that is enough questions for now. I am looking forward to reading your answers.
