About this event

Insufficient emissions reductions could lead to warming scenarios beyond 1.5°C that trigger global changes and feedbacks in the cryosphere that may be rapid and to some degree irreversible (several tens of thousands of years). The most significant dynamics include sea-level rise from polar ice sheets; polar ocean acidification; mountain glacier loss; permafrost thaw and related CO2/methane emissions; and, Arctic sea ice loss.

All these changes will impose dramatic impacts on the global climate system, as well as local people and ecosystems. The near-immediate cryosphere response as temperatures rise beyond 1.5°C and CO2 passes 450ppm, underscores the urgency of sharp emissions reductions by 2030 as the IPCC has outlined.

With even temporary overshoot above 1.5°C, researchers believe the cryosphere system is close to changes that will persist for many generations, but which may still be averted with enough reductions and forward planning.

The briefing will include a Q&A with the speakers.

While there are benefits from this approach, there are also some barriers to its use. This POSTnote examines the value of these approaches, and the technical and ethical challenges for wider implementation.
