Melting glaciers could help stop global warming

No mention of the loss of albedo. Harvesting and shipping rock flour from Greenland to sequester carbon in ag fields in Denmark sounds a little far-fetched in terms of how that would add up to a net reduction of CO2.

The current article Glaciers are melting, but the dust left behind may help save us is less misleading than the posted headline (maybe it changed?) and the page's The unassuming material that could soak up carbon emissions a little more-so although it has a clickbait ring.

Futurama had this idea a long time ago

This is about the rock dust left behind a melted glacier, not the actual ice in the glacier.

Some rocks absorb CO2 as they weather. Also, rocks provide minerals to fields which provide extra benefit.

Greenland with melted glaciers aren’t the only option. Olivine is rock that absorbs CO2 in seawater. We could grind and dump gigatons of it, and it is more accessible.

Yes, like GP said the harvesting and shipping of huge amounts of rock seems iffy on actual sequestering any carbon net.

Click-bait title that doesn't match the actual title pointing to the real just of the article (it's not the flavors melting but three ground up rocks left behind)
