Core Viewpoint - The Earth has crossed its first climate tipping point, with global temperatures rising 1.4°C above the late 19th century levels, surpassing the critical threshold midpoint of 1.2°C for coral reef extinction [1] Group 1 - The report titled "Global Tipping Points Report" was authored by 160 scientists from 23 countries [1] - The critical point for warm water coral reefs is reached when global temperatures rise between 1°C and 1.5°C [1] - Exceeding this tipping point will trigger a series of chain reactions that will accelerate global climate deterioration [1]
