Across multiple sectors, global climate outcomes at 2°C warming could be much more extreme than those expected in a 3°C or 4°C warmer world. This highlights the urgency of ambitious mitigation strategies aimed at limiting global warming well below 2°C. www.nature.com/articles/s41...
Moderate global warming does not rule out extreme global climate outcomes - Nature
Extreme global climate outcomes may occur even under moderate 2 °C warming and may turn out to be more extreme than model-averaged projections at 3 °C or 4 °C warming.
