Good news if you hate ice...and existing coastlines.

I blame those who deny climate change.
ReplyDeleteSoon I will live closer to the sea.
ReplyDeleteThe arctic ice cap floats on the sea so melting it doesn't change the sea level. The same for the ice shelves of Antarctica.
ReplyDeleteI would expect that disappearance of arctic ice will significantly impact weather in the northern hemisphere.
Phillip Landmeier And the melt of glaciers on land...
ReplyDeleteRiiight... didnt al gore aleady predict this happening and it hasnt... the inconvenient truth is a lie.. quit buying into the lie that is manmade climate change.
ReplyDeleteHere's a crazy idea. We need water to colonize the moon, right? Since we've apparently got so much extra with the ice melting, let's just stick some of it up there. After all, we'll need somewhere to go after we're done trashing this planet.
ReplyDeleteSteve Welsh That's the melting that does affect sea level. But the post was specifically about arctic sea ice.
ReplyDeletePhillip Landmeier I am not that sure I will care about minutiae when I'm treading water.
ReplyDeletePhillip Landmeier -- greenland and the antarctic are both ice caps on land, rather than floating, so the ice is not displaced by water. The larger problem is that when the world heats up, so do the seas, and thermal expansion of water will increase the sea levels more than the addition of water from melted icecaps/glaciers.
ReplyDeletePhillip Landmeier Arctic sea ice melting raises the temperature of the atmosphere, thereby accelerating melting of glacial ice. That was discussed in the article.
ReplyDeleteCraig Froehle Yes, I mentioned something to that effect.
ReplyDeleteWhat's more, Greenland is melting faster than expected. There are unexpected melt mechanisms that we don't yet understand. There's evidence that some Greenland ice is melting from the bottom which nobody expected. So the forecast models could be off significantly.
Don't buy land lower than 60 feet MSL. Lol.
Craig Froehle Water absorbs heat much better than ice. When I was making submarine patrols between Greenland, Iceland and the UK back in the early 80's, we observed a significant thermocline around 200+/- feet, warmer above, colder below. The two layers didn't mix much. Below the layer, we were effectively hidden from surface sonars. Warmer water is less dense than colder water, so we would have to pump auxiliary tanks to sea to lighten the ship when we went up to periscope depth. Under the ice, there is virtually no thermocline, but the surface salinity is reduced when ice melts, also causing the water near the surface to be less dense.
ReplyDeleteMac Baird Interesting!
ReplyDeleteMac Baird For a reality check on my understanding...let's say you're in the warm layer and set ballast for a slow descent. When you reach the thermocline your descent stops and you float at the boundary until you take on more seawater to continue descending. Would that be roughly correct?
ReplyDeletePhillip Landmeier
ReplyDeleteAbsolutely correct. The bigger the thremocline, the more water required to pump in/down or out/up to return to neutral buoyancy. One could always force the ship through the thermocline with more speed, but then you would need to maintain a bubble/angle to maintain depth. The other concern was sea state. The larger the waves, the heavier we would have to trim the ship to keep from broaching. Going up to PD in the Arctic winter storms was never much fun. I experienced 30 degree rolls once. With the ice cap getting smaller each summer, there will be a greater Naval presence in the years to come. Frankly, I would not want to be up there in anything other than a submarine for most of the year. No matter how big the waves got on the surface, at a depth of 400+ feet, the ship was steady as a billiard table with all the comforts of a 5 star hotel.
I just love global warming. 2 years, 4 years, 6 years,.., what does this really matter? The damage is already done with more to come. Has anybody seen the major networks report the ocean liner cruising the northwest passage? Pretty big news huh. We deserve everything that's coming.

ReplyDeleteNuclear power doesn't seem scary anymore!
ReplyDeleteCarl Page
ReplyDeleteOperationally, nuclear power technology has gotten safer, but the problem with disposal of nuclear waste has grown. There is still no good solution for the waste and its potential danger to the environment. We need to do a better job of designing our installations to avoid a repeat of Fukushima. Here is a photo of the decommissioned reactor from one of my submarines on a barge headed to a permanent storage site for the next 1000+ years. Our waste containment technology needs to improve.
http://websitesbycook.com/tecumseh/page1/ All civilian nuclear waste is stored on site forever because there is no way to safely transport it.
THe thing to do with nuclear waste is to chemically bond it with a salt, so it can't melt down. THen you put it in an MSR and use it for energy for 5 years. That burns off all the transuranics and the fissile uranium. Then you take the waste for that and store it carefully for 300 years before it is safe. There is no reason to worry about storing waste beyond 300 years if you use the proper MSR reactors.
ReplyDeleteRail gun the waste into the sun.
