The Future of Global Warming: Tackling Committed Warming and Post-Net-Zero Challenges

A new study warns that climate tipping points, such as the melting of ice sheets and loss of the Amazon rainforest, could be triggered by "committed warming," where global warming continues even after greenhouse gas emissions are held constant. The study presents three scenarios for rising global temperatures, including increased fossil fuel use, reaching net zero emissions, and the current trajectory. Without swift adoption of net zero policies and emission cuts, temperatures may climb by about 2.7°C by 2100, crossing six tipping points. The researchers emphasize the need to limit global warming and avoid catastrophic consequences for ecosystems and human populations.
