- spacehacker 10y agoFortunately, sea ice does not contribute much to the sea level because it displaces about the same volume it will add when melted.
- dharma1 10y agoYep, but it does have other negative effects. https://www.carbonbrief.org/five-reasons-why-the-speed-of-arctic-sea-ice-loss-matters https://www.carbonbrief.org/five-reasons-why-the-speed-of-ar...
- saosebastiao 10y agoAlbedo is a measure of how well the earth’s surface reflects sunlight. Snow-covered sea ice has a high albedo and reflects 85 per cent of sunlight. But the open water revealed as ice melts is darker and absorbs more – reflecting just seven per cent. Yep, that's terrifying.
- wiredfool 10y agoBut sea ice has an albedo affect. Dark seas absorb more heat.
- flukus 10y agoDepends on where it's coming from. Some of those increases are because of on land glaciers thinning and spreading over the ocean.
