The United Nation's Intergovernmental Panel on Climate Change estimated in 2011 that carbon dioxide emissions had to be limited to 1000 gigatons to have a two-thirds chance of keeping global warming below 2°C.
By mid-October, there were more than 100,000 fires raging in the Indonesian provinces of Sumatra and Kalimantan that had released an estimated 995 million metric tons of carbon dioxide into the atmosphere over the past four months. This is just short of 1 gigaton.
