According to a research that is published in the journal “Nature”, The annual river ice cover will decline by about six days for every one degree Celsius increase in global temperatures, posing economic and environmental consequences.
This research is done by using more than 400,000 satellite images taken over 34 years to measure which rivers seasonally freeze over worldwide, which is about 56 per cent of all large rivers.
This research also found that widespread declines in monthly river ice coverage. And the predicted trend of future ice loss is likely to lead to economic challenges for people and industries along these rivers, and shifting seasonal patterns in greenhouse gas emissions from the ice-affected rivers.
Comparing river ice cover from 2008-2018 and 1984-1994, the team found a monthly global decline ranging from 0.3 to 4.3 percentage points. The greatest declines were found in the Tibetan Plateau, eastern Europe, and Alaska.
The Rocky Mountains, northeastern US, eastern Europe, and Tibetan Plateau are expected to take the heaviest impact.
