Havsirkulasjonen i Nord-Atlanteren
Fra Golfstrømmen utenfor Florida driver vinden vannet nordover og østover mot Europa i Atlanterhavsstrømmen, før det styres inn i de nordiske hav og Norskehavsstrømmen. I nord avkjøles vannet, synker og strømmer tilbake sørover som en dyphavsstrøm. Både vinden og nedsynkningen er med på å drive denne storskalasirkulasjonen i Nord-Atlanteren.

North Atlantic overturning circulation
zhlédnutí 605Před měsícem
From the Gulf Stream off the coast of Florida, the wind drives the water northward and eastward toward Europe in the Atlantic Current, before steering it into the Nordic Seas and the Norwegian Current. In these northern regions the water cools, sinks and flows back south as a deep ocean current. Both the wind and the sinking contribute to driving the large-scale circulation in the North Atlanti...

The Gulf Stream is a concentrated band of warm water flowing northward off the east coast of North America. It continues across the Atlantic toward Europe as the North Atlantic Current. The current splits into separate branches at several stages. The branch that continues northward through the Norwegian Sea is called the Norwegian Current.

Golfstrømmen er et konsentrert bånd av varmt vann som strømmer nordover langs østkysten av Nord-Amerika og utover i Atlanterhavet som Atlanterhavsstrømmen. Strømmen deler seg flere ganger.

      well, there always will be some circulation, because the equator is hotter than the poles, and because the earth spins. but there has indeed been some concern that climate change may weaken the northeastward currents in the north atlantic, the result of which would be europe getting colder.

    Methane CH4 is a gas naturally produced underground in anaerobic conditions (reduction environment) where you have organic decay in the soil.. When it eventually seeps up into the atmosphere, the ultra violet light from the Sun and lightning storms convert the CH4 in the presence of atmospheric oxygen to plant food and water. Carbon is the first element created in the Sun by fusing three atoms of Helium. the Carbon atoms with a valency of 4 combine with the Suns Hydrogen atoms to make the first compound molecule created in the Sun Methane CH4. Methane like CO2 and H2O are the first three gasses created inside the Sun in the Fusion processes creating the basis of all organic Carbon life. To talk of it as a danger to human life on Earth shows a complete ignorance of how life is created, let alone the roles that these three gasses play in all carbon life here. When you impregnate Science with ignorance and fear, it does not bode well with making good decisions.

    You have to realize that 97% of greenhouse gases are cause by nature. 3% by man. How can you drastically reduce something that is only 3% man fault???? SO the glaciers are melting and Artic temps are rising. That is what happens after an Ice Age. Are sea levels going to rise?? NO. ice is lighter than water. Here is a good example. Have you ever put ice in a glass of water? When the ice melted, did it overflow the glass or stay at the same height or even decreased. That is why there has been no ocean levels rising. I live along Lake Michigan in Indiana. The Lake rises and lowers every year. For a few years it might be higher that average and for a few years it might be lower. I have seen the lake rise and lower over my 60 years living here. Today, it is 7" lower than last year. There has been multiple Ice Ages over millions of years. One day, it will get colder and a new Ice Age will start. Of course this is a few 100,000 years in the future but it will happen. Also, 90% of Earths history, there has been no ice on the polar caps. So actually no ice on the poles is normal. This global warming crap is just a way for the rich to get richer and those in power to get more power, that is all.

      The headline does not only say "carbon", it says "carbon storage", a well-established term. As Althuizen talks about two of the carbon-based greenhouse gases that comes out of thawing permafrost, carbon dioxide and methane, carbon storage fits well as an overall term.

      "on average depth of arctic permofrost is 5,800 feet deep". Total rubbish. Geothermal heat warms by 1 degree per 40 metres deep so at 1,768 m (5,800 feet) deep is 44 degrees warmer than average surface temperature over a few hundred thousand years. It'll always have been ~40 degrees down there for the last several million years. Geothermal heat below and massive thermal insulation above. So no permafrost at all.

Remove the atmosphere/GHGs and the earth becomes much like the Moon or Mercury, a barren rock with a 0.1 albedo, 20% more kJ/h, hot^3 on the lit side, cold^3 on the dark.
