Climate change in the United States
Because of global warming, there has been concern in the United States and internationally, that the country should reduce total greenhouse gas which is relatively high per capita.In 2012, the United States experienced its warmest year on record. As of 2012, the thirteen warmest years for the entire planet have all occurred since 1998, transcending those from 1880.From 1950 to 2009, the American government's surface temperature record shows an increase by 1 °F (0.56 °C), approximately. Global warming has caused many changes in the U.S. According to a 2009 statement by the National Oceanic and Atmospheric Administration (NOAA), trends include lake and river ice melting earlier in the spring, plants blooming earlier, multiple animal species shifting their habitat ranges northward, and reductions in the size of glaciers.Predicting future climate changes are fraught with difficultly. Some research has warned against possible problems due to American climate changes such as the spread of invasive species and possibilities of floods as well as droughts. Changes in climate in the regions of the United States appear significant. Drought conditions appear to be worsening in the southwest while improving in the northeast for example.President Barack Obama committed in the December 2009 Copenhagen Climate Change Summit to reduce carbon dioxide emissions in the range of 17% below 2005 levels by 2020, 42% below 2005 levels by 2030, and 83% below 2005 levels by 2050. In an address towards the U.S. Congress in June 2013, Obama detailed a specific action plan to achieve the 17% carbon emissions cut from 2005 by 2020. He included such measures as shifting from coal-based power generation to solar and natural gas production.
