A quick look at the 2012 record flood in the Amazon Basin

The water level at the Manaus Port on the Negro River reached its record value of 29.97 m on 29 May 2012. This is higher than the previous record in the year 2009 by 20 cm. The rise of the level from November 2011 till the record maximum is the highest in the past several decades. A cooler South Atl...
