Volcanic activity


With an extent from the Arctic Ocean to the Baltic Sea, there are in the Kingdom of Denmark only pronounced volcanic activity in our North Atlantic territories. In 2014 Denmark made a submission that the Lomonosov Ridge is a natural prolongation of the Greenland landmass, and that it constitutes a submarine elevation the Greenland continental shelf will extend beyond the North Pole. From the depths of the North Pole is raised the Gakkel ridge, a gigantic submarine volcanic mountain that it extends range for miles from Greenland to Iceland and to Siberia. With its deep valleys 5,500 meter beneath the sea surface and its 5,000-meter-high summits, Gakkel ridge is far mightier than the Alps. The global mid-ocean ridge system is the most extensive magmatic system on our planet and is the site of 75 per cent of Earth’s volcanism – Nature August 2019. A US sonar survey in 2001 revealed two previously undiscovered volcanoes beneath the pack ice along the ultraslow-spreading Gakkel Ridge. Recent Arctic ice pack melting may well be due to Gakkel Ridge volcanism.


In Greenland, a long “thermal track” was recently revealed beneath the miles-thick ice sheet that covers the giant island. The scar’s track through Greenland still shows a measurable heat signature. It may mean that Greenland can expel its ice faster – NASA March 2019.

Temperature

  Understanding Global Warming Temperature is getting more pleasant Figure 1.   Hadley Centre Central England Temperature (HadCET) dataset + DMI+ NOAH The CET dataset represents the world’s longest continuous instrumental temperature record. Danish temperature data have been superimposed for comparison. The earliest Danish measurements were taken from the top of the Round Tower in Copenhagen and subsequently converted to a national average, with an estimated uncertainty of ±0.5 °C. Also shown are global temperature values from NOAA (National Oceanic and Atmospheric Administration), adjusted by adding 13.7 °C (the IPCC’s assumed preindustrial average) plus global anomaly for 1980 +0.51 °C, resulting in an approximate absolute temperature of 14.2 °C....

Henrys Law

  Understanding Global Warming Henrys Law Figure 1. IPCC Carbon Cycle AR5. Simplified schematic of the global carbon cycle. Numbers represent carbon mass and exchange fluxes in Gt (Pg) carbon per year – hyperlink . The enclosed part [our highlighting] shows a chain of circles connecting the atmospheric carbon with that of the sea - quite to the sediment on the ocean floor. A total upward flux of 207,1 GtC is indicated. According to Henry’s law , a balance must be maintained between the concentration of CO₂ in the atmosphere and in the ocean’s surface layer. As chemical and biological processes remove CO₂ from surface waters and transport it to deeper layers, space is created for additional CO₂ uptake at the surface. However, this downward transport introduces a delay in the system’s overall response. Consequently, only an amount of CO₂ roughly equivalent to half of the fossil fuel emissions is absorbed by the oceans on an ongoing basis. An amount corresponding to the r...

Egtved Girl

  Understanding Global Warming The Egtved Girl and her time   Karin Margarita Frei of The National Museum of Denmark, Copenhagen has convincingly told us about the Egtved girl and her age as a warm and fruitful period - also warmer than today, hence the interest in the Minoan Warm Period - hyperlink .  That the climate was really warmer at that time can be deduced from the fact that in the Bronze Age, millet was grown in southern Scandinavia. Millet is grown today in tropical and subtropical areas. No remains of stables from that time have been found. Apparently the cattle were kept out all year. So probably the climate in the middle of the Bronze Age was about 2 degrees warmer than in the present. 40,000 Bronze Age mounds have been registered. There have been many more, but especially on the islands they have been plowed down. The large number, testifies to an unbelievably rich time, but also to a signifi...
