Tapanuli orangutans survive only in Indonesia’s Sumatran rainforest where a mine expansion will cut through their home. Yet the mining company says the alternative will be worse A small brown line snakes its way through the rainforest in northern Sumatra, carving 300 metres through dense patches of meranti trees, oak and mahua. Picked up by satellites, the access road – though modest now – will soon extend 2km to connect with the Tor Ulu Ala pit, an expansion site of Indonesia’s Martabe mine. The road will help to unlock valuable deposits of gold, worth billions of dollars in today’s booming market. But such wealth could come at a steep cost to wildlife and biodiversity: the extinction of the world’s rarest ape, the Tapanuli orangutan. The network of access roads planned for this swath of tropical rainforest will cut through habitat critical to the survival of the orangutans, scientists say. The Tapanuli (Pongo tapanuliensis), unique to Indonesia, was only discovered by scientists to be a separate species in 2017 – distinct from the Sumatran and Bornean apes. Today, there are fewer than 800 Tapanulis left in an area that covers as little as 2.5% of their historical range. All are found in Sumatra’s fragile Batang Toru ecosystem, bordered on its south-west flank by the Martabe mine, which began operations in 2012. Continue reading...

Sun-dimming risks putting the planet’s thermostat under Donald Trump’s control. Better to adopt the precautionary principle with high-stakes science It is fitting that this week’s UN environment talks are in Nairobi, with Africa shaping the global climate conversation. The continent’s diplomats are dealing with the vexed question of whether it is wise to try to cool the planet by dimming the sun’s rays. While not on the formal summit agenda, on the sidelines they are arguing that it’s time to stop promoting solar geoengineering technology as a solution to global heating. It’s hard to disagree. African nations have acted because they don’t want their continent to become a test bed for unproven schemes to spray particles into the high atmosphere to reflect sunlight away from Earth for a small, uncertain cooling gain. They point to environmental, ethical and geopolitical risks. That’s why the continent is pushing for a global “non-use” agreement that would rule out public funding, outdoor experiments, patenting and official promotion of these technologies.

Species extinct as breeding birds in Britain since 1416 to be reintroduced in Barking and Dagenham as part of rewilding effort Above the roar of traffic, the rumble of the tube and the juddering construction noise of a towering new datacentre in Dagenham, east London, will soon rise a beautiful and unlikely melody: the bill-clattering of white storks. The birds will next year make a historic return to the UK capital as part of an ambitious rewilding effort to bring charismatic nature into busy city communities. Continue reading...
