Indonesia may be on the front lines of the fight against global warming, but many of its people are climate sceptics. A 2019 survey found that Indonesia – the world's biggest Muslim-majority country – has the highest proportion  of climate change sceptics globally. About 18 percent of respondents said human activity is not affecting the climate, compared with 16 percent in the US. Campaigners are hoping that Islamic authorities and mosques can help raise awareness of environmental issues. They've condemned deforestation, installed solar panels on their premises and spearheaded waste recycling. FRANCE 24's William de Tamaris, Justin McCurry and Ismutia Rahmi report from Java and Bali.
