A recent study suggests that the Amazon rainforest is approaching a 'hypertropical' climate, characterized by extreme heat and drought, which could lead to significant tree die-offs and weaken its role as a carbon sink. Without drastic reductions in greenhouse gas emissions, the region could face up to 150 days of intense drought conditions annually by 2100. The study highlights the vulnerability of certain tree species and warns of broader ecological impacts, including potential effects on other tropical forests worldwide.
