I was recently invited by the editors of the journal Tropical Conservation Science to write an update of a 2013 article on deforestation in the Brazilian Amazon that I had published with Sarah Roquemore and Estrellita Fitzhugh. They asked me to review how deforestation has changed over the past five years.

Over the past several years, one of the few pieces of hopeful news about global warming has been the annual release of data from Brazil on its rate of Amazon deforestation. Since forests are immense storehouses of carbon, deforestation causes high levels of greenhouse gas emission. Brazil, which contains about 60% of the Amazon forest, is key to those emissions, and over the last six years it has made important progress in reducing its deforestation rate.
Today, the new data for 2011-2012 were released, and once again they are a ray of sunshine on an otherwise gloomy day. They show a decrease of deforestation to 4,656 square kilometers – down 27% from last year.
