Arctic Sea Ice Road Maps

Knowledge Gaps

Physical science / mechanism

Version published: 
  • Discrepancies exist between top-down and bottom-up methane budgets (Nisbet et al. 2021).
  • Need to determine evolution of methane sinks in different climate scenarios and how that influences methane lifetime.
  • Do any proposed methane reduction management strategies for wetlands have the potential to reduce additional emissions caused by climate change (Ury et al. 2024) and prevent loss of Arctic sea ice? Can protecting Arctic wetlands secure stores of methane in permafrost?

Engineering needs (technical feasibility)

Version published: 
  • Need verification of methane emissions (Nisbet et al. 2021).
  • Need further solution development across sectors, especially for livestock.

Cost

Version published: 
  • How to mobilize appropriate funding and finance to support urgent action on methane in less developed sectors?

Social risks / benefits

Version published: 
  • Increase understanding of co-benefits of emissions reductions for climate and health (AMAP 2021 full report). Need to increase spatial resolution and time periods of global model datasets for improved assessments of changes in local air quality and regional climate (AMAP 2021 full report).
  • Observations of air pollution levels and impacts on human health and vegetation in the Arctic are limited. This is needed for epidemiological studies and for establishing baselines for future comparisons (AMAP 2021 full report).
