Global Warming

Global Warming Began Way Earlier Than Previously Thought

A group of researchers at the University of Cambridge have found evidence that the warming of the Arctic Ocean began much before the current calculations offered by modern instrumental measurements. It is observed that the rise in global temperature had been initiated way back at the beginning of the last century. ‘Atlantification,’ a process in which the influx of warmer and saltier water in the Arctic Ocean is witnessed, has been prevalent since the beginning of 1900. Researchers used the chemical signatures found in marine microorganisms and based the study on them. The paper acts as a link between the North Atlantic and the climate of the Arctic.

Atlantification will lead to the melting of snow due to the introduction of warmer and saltier water. As the ocean surface gets exposed to sunlight, the release of heat into the atmosphere will melt the permafrost, a layer that has capsuled a large amount of methane, a much more damaging greenhouse gas than CO2.
