Oceans and Global Warming
Oceans and Global Warming
Facts are that the global temperature is rising, CO2 concentration has also risen and both are likely to rise further. There is also indisputable evidence that global temperature has varied widely over past millennia.
However, following should be born in mind: by far the greatest amount of CO2 is released by the world’s oceans; they are also the largest absorbers. It should not be assumed that both sides of this process are always in an equilibrium. The release of CO2 is not, but its absorption may be affected by the Sun.
Increased UV and gamma radiations are reaching the oceans’ surface during periods of high sunspot activity. There are also charged particles emanating either from solar or galactic activity. All of these to a certain degree damage living cells. UV and gamma radiation have caused increase in skin cancers, while charged particles can have disastrous effect on communications, power grids, satellites and astronauts working in space etc. Clouds provide protection from UV rays, Van-Allen belt provides partial protection from charged particles and the atmosphere to some extent from gamma rays.
If solar activity is on increase (as it has been since 1860-s) then amount of all 3 kinds of radiation would be on increase. Coincidently, the strength of the Earth’s magnetic field has been decaying during same period (61 to 54 micro Tesla) by about 11%, so radiation protection of Van-Allen belt has also been reduced.
This increase of the harmful radiation is causing reduction bio-mass of the oceans’ surface phytoplankton, the largest absorber of CO2 on the Earth’s surface, either through direct destruction of its cells or process of sterilisation by irradiation. Result of this is a reduced uptake of CO2 from the atmosphere and rising in the ‘green-house’ effect. There are already quantifiable evaluations of reduction in the efficiency of phytoplankton. Reverse process takes place during reductions in the solar activity causing global cooling end may even trigger onset of ice age (eg. solar activity was at a minimum between 1650-1710 causing considerable cooling known as ‘Little Ice Age’).
