According to the U.S. Geological Survey, the possibility of more droughts and more intense storms will increase as global surface temperatures rise. This connection is what's behind environmentalists' projections that the world will be forced to confront the potentially dire and deadly consequences of more droughts and other adverse events if changes to the status quo are not implemented. The USGS notes that the link between rising surface temperatures and adverse events like powerful storms is not all that complex. As more water vapor is evaporated into the atmosphere, which occurs as global surface temperatures rise, the vapor becomes fuel for more powerful storms. In addition, more heat in the atmosphere and warmer ocean surface temperatures produce higher wind speeds during tropical storms. Higher wind speeds increases the intensity of tropical storms and poses a significant threat to individuals who live in areas where such weather events are common.
