Almost everyone worries about global warming, but there may be a new problem that likely will happen while we are alive. Every eleven years the sun lets off an enormous amount of radiation called a solar storm. Scientists are predicting that the next solar storm will occur in 2012 and it will be the largest solar storm ever. Scientists however are less worried about the effects on the human race, but they worry our power grids and satellites will fail. This solar storm will happen in the next few years, so we need to take the appropriate actions to make sure it will not cause big problems.
