Ice is important to keeping Earth's temperatures and sea levels steady. Ice reflects the heat of sunlight back into space, reducing global warming. But when ice starts to melt, less sunlight is reflected back. Instead, the oceans and land absorb the light, thus raising the overall temperature and adding energy to a vicious circle. It's known as a feedback loop. Shown here is a NASA rendering of icebergs reflecting sunlight. (NASA/Goddard Space Flight Center Scientific Visualization Studio)
