Could Freezing Arctic Sea Ice Combat Climate Change?

Could Freezing Arctic Sea Ice Combat Climate Change?

60-Second Science vor 1 Jahr

Refreezing the melting sea ice in the Arctic is more complicated than you would think. The U.K. is funding geoengineering experiments like this one to curb the effects of climate change.

The year-round sea ice in the Arctic is melting and has shrunk by
nearly 40 percent over the past four decades. Geoengineering
companies such as Real Ice are betting big on refreezing it. That
may sound ridiculous, impractical or risky—but proponents say we
have to try. The U.K. government seems to agree, investing millions
into experimental approaches such as Real Ice’s. Pulitzer Center
Ocean Reporting Fellow Alec Luhn is taking us with him to the
Arctic to see what it takes to freeze sea ice in the already
freezing cold. Recommended reading: Read Luhn’s feature in the June
2025 issue of SciAm, which will be released on May 20:
