Declining sea ice to lead to cloudier Arctic



Arctic sea ice has been declining over the past several decades as global climate has warmed. Moreover, sea ice has declined more quickly than many models predicted, indicating that climate models may not be correctly representing some processes controlling sea ice. One source of uncertainty in models is feedback from cloud cover. Sea ice can affect cloud cover, as melting sea ice and increased evaporation from the ocean surface can lead to increased cloud formation.
