The causes of global warming, added ocean
Oceans, oxidized by combustion of fossil fuels by man, can enhance the process of global warming by reducing the production of gas, protects the planet from solar radiation, according to a study published in the latest issue of the journal Nature Climate Change. The researchers caution that the observed effect is not taken into account by them in any prediction of climate change.
The paper says that the carbon dioxide emissions from human activities lead to global warming. The sun’s rays pass through the atmosphere, while the heat reflected by the earth is delayed. A mixture of dust and gases in the lower atmosphere works on the principle of transparency of the greenhouse. This creates a greenhouse effect.
All this also leads to a decrease in the pH of the oceans – the water is oxidized, the amount of dimethyl sulfide (CH3SCH3), volatile sulfur compounds emitted by plankton, are reduced. Dimethyl sulfide that came from salt water into the atmosphere to reflect solar radiation and thus lowers the surface temperature of the Earth, said the study.
If you add this effect to all the climate models, the reduction of emissions of dimethyl sulfide in the atmosphere by 18 percent by 2100 could lead to an increase in global temperature by 0.48 degrees Celsius.
As far as we know, we are the first to determine the potential impact of changes in the global sulfur cycle as a result of ocean acidification on the Earth’s climate. We propose to take into account the possible mechanism of action of ocean acidification on the climate in the preparation of future climate models, they write in their paper, the authors of the study.
The researchers also warn that ocean acidification may have other, as yet undiscovered effects on the biology of the ocean, which may cause a further decrease production of protective gas.
