Scientists Discover a Novel Way to Refreeze Arctic Ice

Researchers are creating a novel approach to "refreeze" the Arctic Sea in order to mitigate the effects of climate change on the region. By injecting saltwater into already-frozen regions, this technique may contribute to the thickening of sea ice, according to promising early testing.

Climate Change and solution to the Climate Change threat to Arctic.

• Changing climate in the Arctic can be sudden, with the potential for the region to be ice-free during summer months as soon as the 2030s, creating widespread consequences for ecosystem and climate stability across the globe.
• Arctic sea ice is disappearing at almost 13% each decade.
• Pumped seawater on thin ice in winter to freeze it and make ice thicker
• This is done by mapping thin ice, cutting holes through the ice, and using those holes to pump seawater up through.
• Some experiments use hydrogen as a renewable energy source, which makes it an environmentally-friendly process.
• Potential impact: Some worry about things like less snow cover, which could affect wildlife.
• It sounds promising, and claims to be part of the climate change solution.
