The world’s oldest cave paintings on the Indonesian island of Sulawesi are under threat as heat and smoke from the country’s worst wildfires in more than a decade risk accelerating the deterioration of the more than 67,000-year-old works of art, according to researchers. Indonesia is battling its most intense forest and land fires since 2015 as a severe El Nino drives up temperatures and reduces rainfall, leaving its forest and peatland vulnerable to fire.
