The sun is literally a burning ball of hydrogen, as it burns it uses up the hydrogen and thus loses mass which makes it grow bigger (because it has a lower gravitational pull) and colder (because it's using it's fuel). It'll eventually become a "red giant" - many times bigger than the current sun, but also cooler.

Again though, we're talking timeframes of BILLIONS of years here, the changes within the entire span of human history are so small they can barely be measured let alone cause any actual change on Earth.
