Another group of scientists has studied the effects of changes in cloud brightening caused by ship exhaust and concluded:
- Recent regulations on ship sulfur emissions have decreased ship tracks and resulted in +0.12 Wm−2 of radiative forcing
- Observed cloud anomalies are correlated with observed ocean temperature anomalies and shipping radiative forcing
- Reduced ship emissions may have accelerated global warming contributing to recent warm Northern Hemisphere surface temperatures
