Temperatures on the Earth’s surface and moisture levels in the atmosphere have been on the rise. These two factors might be at the root of the drastic change in weather patterns causing severe droughts, heat waves, heavy rains and other extreme weather phenomena.
In its September 2012 edition, the National Geographic magazine featured an extensive article on extreme weather affecting the U.S.
As the economic damage from Hurricane Sandy is still being evaluated, we took a look at the damage from weather/climate-related disasters over the past 30 years. The National Climatic Data Center (NCDC) at the National Oceanic and Atmospheric Administration keeps detailed statistics of all weather disasters in the US. One of the visualizations the NCDC has created is a thematic map of billion-dollar weather events, which can be seen above. The map shows the number of events that caused at least a billion dollars in damage by state. Southern states suffered the most damage up until 2011. The colors in the map may look significantly different once the total tally of Sandy is calculated.
