As the ocean gets warmer more water vapor enters the atmosphere, leading to more warming, etc. Unfortunately the press release doesn't say much about why the Earth doesn't continue to heat up, but does provide several possible explanations. Before the flame wars start again, you might also want to read brief NASA summary of global warming science. (a site I work on)"
