Earlier on https://planet-earth-2017.com/2015/12/19/why-co2-is-on-the-rise/ I explained that huge amounts of Methane (CH4) are stored deep in the oceans at 500 meters below sea level, in the form of solid Methane Hydrates. Methane that is found in the ocean is produced by microbes within the sea floor that break down organic matter, which sinks down from the sunlit zone near the surface. Organic matter is composed, for example, of the remains of dead algae and animals, as well as their excrement.
Warmer Oceans could cause the hydrates to destabilize, and as a potent greenhouse gas, Methane would escape unused into the Atmosphere, encountering Oxygen O2 to bond with and form Carbon Dioxide (CO2) and Water (H2O); for each 1 molecule of Methane, comes 3 molecules of green house gases; CH4 +2O2 = CO2 + 2H2O.
In the above map the sea bed topography is calculated by the Google map application. The sea bed in the Indian Ocean in the mid distance between Australia and South Africa is as shallow as 500 meters for an area of 1,266,000 kilometer square approximately.
A recent survey by Berkeley in 2018 shows that at this specific segment of the Indian Ocean the Temperature has increased when compared to 1979-2000 time scale Temperature.
The Indian Ocean drifts tell of 2 sources. The cold one is flowing from the west where the magnetic field at the tip of the African continent have dropped by 11% (28,044 nT in 1979 to 24,852 nT in 2018), referring to NOAA Magnetic Field Calculator; allowing more charged particles, from the Sun, namely Protons to penetrate into the Thermosphere layer of the Atmosphere to the surface level, bombarding the ocean and warming its temperature. The West Wind drift brings warmer waters along its path that intersects with the shallow ocean area addressed earlier in the mid distance between Australia and South Africa. Such warm waters help releasing Methane into the air, causing a localized increase of temperature over such 1,266,000 km. Obviously such an increase in Temperature can not be man made being thousands of kilometers from any man made structure or civilizations.
Similarly the regions highlighted in the map as region A in the Arctic and region C in Antarctica, where civilizations are thousands of Kilometers away have witnessed rising temperatures. While NOAA Magnetic Field Calculator shows a drop in the magnetic field strengths covering such areas due to the migration of the 2 magnetic poles eastwards simultaneously, I have demonstrated on Earth Temperature page of this site, that the Temperature Belts of homogeneous climates are centered around the Magnetic Poles. As the Magnetic Poles continue to moving towards the east, so will the Temperature Belts tilt along causing warmer belts (namely, continental belt) to replace the belt that the Magnetic Poles has withdrawn along its move (namely, the polar belt).
I called earlier that a complete survey of the Methane deposits into the seas and oceans should be made, magnetic field strength change to be plotted against, and volumes of released Methane or for better description CO2 and H2O be properly compared versus fossil fuel emitted CO2 in order to adopt the right strategies to combat, if possible, the true drivers behind global increase of green house gases and therefore overall Atmosphere warming.
