Earth may cross 1.5Â°C mark set in Paris deal by 2026: Study
Ocean-atmospheric climate fluctuations could accelerate warming, taking global temperature anomalies past the 1.5Â°C barrier negotiated in the Paris agreement, according to an Australia-based study. The phenomenon, Interdecadal Pacific oscillation (IPO) governs ocean temperatures in tropical Pacific. Scientists said IPO may take temperatures beyond 1.5ÂºC mark by 2026 in its positive (warm) phase.
