Limiting Global Warming To 1.8 C Could Prevent Massive Health Losses, Says Lancet Commission

Limiting global warming to around 1.8 degrees Celsius instead of 4.4 degrees Celsius could prevent the loss of 1.89 billion years of healthy life from extreme heat and air pollution.

The Lancet Commission on 21st Century Global Threats to Health identified 17 interlinked catastrophic threats spanning diseases, environmental change, technology, and conflict for 2025 to 2100.

Nuclear conflict and malicious AI were identified as threats with extinction potential, while action to prevent nuclear conflict could avert an estimated 133 million deaths by 2100.
