Two years ago the world signed the Paris Agreement to combat climate change. It included specific pledges to “conserve and enhance” the world’s forests in order to combat rising temperatures. But in the last two years – 2015 and 2016 – we’ve lost enough trees to cover 493,716 square kilometres, according to satellite data recently released by Global Forest Watch (GFW). This is nearly equal to the entirety of Spain – or about four Englands. Currently, deforestation accounts for around 10-15% of annual global carbon emissions. Even as combating deforestation has long been seen as one of the cheapest ways to tackle global warming, GFW’s data shows just how far we have to go. “Forests are fundamentally hard to protect – they are in remote frontiers or in countries with weak governance,” said Liz Goldman, a Research Associate at GFW.
