The Paris Agreement set goals of keeping global temperature rise below 2.0°C and working to keep that rise to 1.5°C to mitigate impacts of climate change. To predict how these temperature rises will intensify the hydrologic cycle, researchers developed a new metric that reflects dry and wet spell intensity and conducted multi-model ensemble experiments. The scenario with 0.5°C more warming showed significantly greater intensification. Disaster risks could be substantially reduced by reaching the 1.5°C target.
