The warming trend in the Arctic is almost as large as the global average in recent decades . The possible causes are : changes in cloud cover , increases in atmospheric , more atmospheric heat transport from lower and sea ice have all been suggested as contributing factors . The loss of sea ice is one of the most cited reasons . When reflective ice melts , a ocean dominates ; this amplifies the warming trend because the ocean surface absorbs sun heat than the surface of snow and ice . This means decrease in reduces Earth ? s . Other possible causes are , which are much less likely to occur in the Arctic than in tropic regions . The storms transport heat from the surface to higher levels of the atmosphere , where global wind patterns sweep it toward higher latitudes . The abundance of thunderstorms creates a near - constant flow of heat away from the , a process that dampens warming near the equator and contributes to Arctic amplification .
