The Arctic will soon see more rain than snow. Scientists say it may speed up global warming
- The Arctic is warming much faster than the rest of the planet, melting sea ice and adding moisture to the air that is likely to increase precipitation
- At the current rate of warming rain could dominate snow in the Arctic before the end of the century, study says
Earlier in August, it rained on the summit of Greenland’s ice sheet for the first time in recorded history, and new research suggests that it not only will become a normal occurrence, but it will happen much sooner than previously thought.
The majority of Greenland is considered part of the Arctic region, along with some of northern Alaska, Canada and Russia.
Known for its frigid temperatures, which average -40 degrees Celsius in the winter, it snows quite often. The Gates of the Arctic National Park and Preserve in northern Alaska records snow at least eight months of the year, and it has snowed at least once in each month of the year in recorded history. But research published in the journal Nature Communications on this week shows much of the region will, on average, experience more rain than snow in the future.
The team of international researchers had previously concluded the region would eventually see more rain, but originally thought it wouldn’t start until around 2090. The new analysis on the region determined the rain would dominate the region as early as 2050 in some areas.

What is China doing about climate change?
The reason for more rain is melting ice. When sea ice melts or breaks away, the open ocean water mixed with rising global temperatures results in more water evaporation, which then leads to rain falling. When Greenland’s summit experienced rain earlier this year, temperatures were above freezing for over nine hours, the third time since 2012 it had happened.
