"In terms of sea level changes, however, the study found the effects of melting are more drastically felt in regions farther from its source. According to InsideClimate News, melting sea ice in the Northern Hemisphere might raise water levels more in “the southern Pacific Ocean and equatorial regions.”
With all due respect, but melting sea ice doesn't raise sea level. It's a scientific fact the author should check carefully before publishing.
- StanislavPetrov 10y agoIce is 90% more reflective. Melting sea ice turns the oceans into giant heat sinks and accelerates warming.
- michaelbuddy 10y agoExcept the most "reflective" areas get the least amount of sun per year anyway.
- flukus 10y agoThey also get it 24/7 for a good chunk of the year.
- marcosdumay 10y agoIt's a big amount. Relative data are useless here, we are talking about a 1-2K heating in a 300K body.
- frabcus 10y agoThe cited source https://insideclimatenews.org/news/21102016/melting-ice-glaciers-sea-level-rise-underestimated-study-Greenland https://insideclimatenews.org/news/21102016/melting-ice-glac... makes it clear it means ice above land, such as Greenland. It also doesn't use the phrase "sea ice" which seems a confusing phrase.
- yequalsx 10y agoThe author made a mistake by interchangeably using "sea ice" and "ice sheet ice". However, your correction itself isn't strictly correct. Melting sea ic can change sea levels by changing the density of the water in the ocean. Also, by melting it changes the amount of sunlight that is reflected. The increase in sunlight reaching the oceans will cause thermal expansion of the water.
- bssrdf 10y agoThe author clearly confused the land ice/ice sheet with sea ice. Do you have evidence supporting your claim that "Melting sea ice can change sea levels by changing the density of the water in the ocean"? I'd be curious to know.
- yequalsx 10y agoSalt water is more dense than fresh water. Add fresh water and you decrease the density of seawater.
- bssrdf 10y agoLoss of Land Ice (Not Sea Ice) = More Sea Level Rise SCHWEIGER: “Melting sea ice has no impact on sea level rise because it’s already floating in the ocean.” Like a glass of ice water. As it warms, the ice in the glass melts, but the total volume of water does not change. However, melting sea ice does contribute to climate change. That’s because white sea ice reflects the sun. So when it melts, the dark open ocean now absorbs sunlight and heats up, raising global temperatures, which in turn cause glaciers and ice sheets on land to melt further. Globally, sea levels have risen four to eight inches since the last century and will continue to rise as the ice melts, putting coastal communities worldwide at risk. http://www.yaleclimateconnections.org/2014/11/loss-of-land-ice-not-sea-ice-more-sea-level-rise/ http://www.yaleclimateconnections.org/2014/11/loss-of-land-i...
- yequalsx 10y agoThe change in density is small but it is not zero. It does change sea level but not in a significant way.
