NASA’s report shows that since the late 19th century, carbon dioxide and other emissions have caused the temperature to rise nearly 2 degrees Fahrenheit.
While 15 of the hottest years on record have occurred since 2001, 2015 is significant because it’s shown the biggest year-on-year increase in temperature since 1998. NASA says this is only the second time that an increase of this much has been recorded since 1880.
