A violent storm ripped through the Amazon forest in 2005 and single-handedly killed half a billion trees, a new study reveals.

The study is the first to produce an actual tree body count after an Amazon storm.

An estimated 441 million to 663 million trees were destroyed across the whole Amazon basin during the 2005 storm, a much greater number than previously suspected.

In some areas of the forest, up to 80 percent of the trees were killed by the storm. A severe drought was previously blamed for the region's tree loss in 2005.
