Web. 09 Jan. 2013.Description: The USA map above shows the amount ofwetness from 1948 to 2009, according to NASA i.e. NationalAeronautics and Space Administration. As shown inmap, the Northern areas are much wet then Southern areas.The state of New York is much wet then Texas, becauseTexas is colored dark brown, which shows that it is ratherdryer then the blue state (NY), which shows more wetness.
  5. 5. U.S. Drought Monitor January 4, 2000 Valid 7 a.m. ESTIntensity: Drought Impact Types: D0 Abnormally Dry Delineates dominant impacts D1 Drought - Moderate A = Agricultural (crops, pastures, D2 Drought - Severe grasslands) F = Fire danger D3 Drought - Extreme D4 Drought - ExceptionalThe Drought Monitor focuses on broad-scale conditions.Local conditions may vary. See accompanying text summaryfor forecast statements. Released Thursday, January 6, 2000 Author: National Drought Mitigation Center
  6. 6. Source: "Drought Monitor Archives." U.S. N.p., n.d. Web.08 Jan. 2013.Description: The maps above show the drought intensity of2 different years. The first map shows the intensity in theyear of 2000, where as the second map shows the intensityin the year of 2013. Both maps have very different intensitiesnoted. As we can see, in 2000 there were no red or darkbrown spots, which show great droughts. Where as in2013, the western areas as the Great Plains consist a greatamount of droughts, which shows how much temperatureand amount of droughts have rose in these years.
  7. 7. Source: "World Wide Daily Drought Risk Map." WorldWide Daily Drought Risk Map. N.p., n.d. Web. 08 Jan.2013Description: The world map above shows thecurrent droughts happening around the world. Theareas with orange and red spots are the ones withthe serious and worst droughts. The Great Plainsand different areas in South America are greatlyaffected by droughts. Asia is not much affected, butsome parts of Europe and Australia are affectedfrom droughts.
  8. 8. Source: "Dessler: †œPaying the Price for ClimateChange†• or a Case of Flawed Statistical Analysis? |Watts Up With That?" Watts Up With That. N.p., n.d.Web. 09 Jan. 2013Description: The graph above shows theamount of rainfall in the months of June-July inTexas over the years of 1890 to 2011. Therewas a major rise spotted from in betweenyears of 2005 and 2007, and a great decreasefrom the year of 2010 to 2011. This shows therainfall is less, which means droughts areincreasing.
  9. 9. ConclusionBased on the evidence shown above, we can determinethat lack of rainfall over long period of time causesdroughts. Droughts can be determined by the amount ofrainfall or the temperature in an area. In next 100 years ifthe droughts percentage rises on this scale, it is possiblethat oceans could get much smaller, and dry land will takeover.
