Borneo already had its climate change
In the south of the island, much of the vegetation grew in the form of peat bogs. These are composed of deep layers of organic matter accumulated over thousands of years.
To plant in peat, the palm producers dug huge ditches to drain the wáter to dry the land.
With this act they released large amounts of carbon into the atmosphere, which contributed to global warming.
The peat when drained quickly decomposes and releases amounts of greenhouse gases into the atmosphere.
Dry peat is highly flammable. (…) In 2006, Indonesia experienced one of the worst seasons of fires that are remembered, when smoke from the fires of Sumatra and Kalimantan triggered a carbon bomb and enveloped the region in a thick haze visible from space. That year the fires carbonized a thousand orangutans.
