For example, Mount Agung has been erupting in Bali over the past week, and it is possible that volcanic sulfate material lofted into the stratosphere will block some of the Sun's energy and temporarily cool the planet. The daily, weekly, and monthly input of energy from the Sun is important for weather processes, ocean currents, and climate. NASA points out that,Over the course of one solar cycle (one 11-year period), the Sun’s emitted energy varies on average at about 0.1 percent. Understanding variations in the Sun's energy is also important in evaluating natural and anthropogenic impacts on climate change. The chart below is very important because it provides the relative roles of factors that influence warming and cooling in the climate system.
