Only halving emissions by 2030 can minimize risks of crossing cryosphere thresholds

Considering cryosphere and warming uncertainties together implies drastically increased risk of threshold crossing in the cryosphere, even under lower-emission pathways, and underscores the need to halve emissions by 2030 in line with the 1.5 degrees C limit of the Paris Agreement.

Automated summary

Taking into account uncertainties in the cryosphere and climate warming, there is a significantly higher risk of threshold crossing in the cryosphere, even with lower emissions. This emphasizes the need to reduce emissions by 50% by 2030 in order to meet the 1.5 degrees Celsius limit set by the Paris Agreement.
