Global warming causes increase in tropical rainfall

Climate change appears to be resulting in higher levels of rainfall in the tropics, reports NASA. Using a 27-year-long global record of rainfall from satellite and ground-based instruments -- the longest and most complete data record available -- scientists found that the rainiest years in the tropics between 1979 and 2005 have mostly occurred since 2001. The rainiest year was 2005, followed by 2004, 1998, 2003 and 2002. The researchers said 2006 may tie 2005 as the rainiest year since 1979.
