The melting of Antarctica is already "irreversible" according to a study conducted by researchers from the POT and the Irvine University of California. The decline that has reached an area of ​​West Antarctica is so rapid that it seems that nothing can prevent glaciers from melting into the sea.

CO2 acts as a greenhouse gas and, when more proportion exists in the atmosphere, the thermal radiation reflected to the space by the earth is smaller. So its thermal effect remains in the atmosphere, resulting in an increase in temperature.

The glacial records that have been elaborated have determined that the concentration of CO2 in the Earth's atmosphere over the last 800,000 years has ranged from 180 parts per million in volume in the coldest times, to 290 ppm. in the warmer times. What are these CO2 variations due to? Well, to completely natural causes and that, therefore, the human being could never control:

  • The digestion of atmospheric CO2 by the formation of reefs in warm and shallow seas, which deplete its content.
  • The production of CO2 that causes volcanic eruptions, which increases the content in the atmosphere.

But, at what point in history should we have started to worry about this matter? Until the middle of the 19th century, natural causes were the only one "problem”Related to CO2, however these natural effects were never anything to worry about, because they were regulatory facts of our planet. However, since the mid-19th century, certain events have been occurring that negatively interfere with the natural evolution of the climate: the human being.

Accelerated, exaggerated, increased, worrisome and now irreversible. This is what scientists have been talking about for decades without really doing anything to solve the enormous concentrations of CO2.

Man has been, for half a century, responsible for the exorbitant increase of CO2 in the air and, consequently, responsible for the thaw of Antarctica.

In the dawn of the industrial age the consumption of fossil fuels, a new source of CO2 production, began. In 1910, CO2 in the air reached 330 ppm, in 2000 it was around 370 ppm, and increasing.

If nature has a regulatory power to stop its own CO2 emissions, perhaps man should have considered 100 years ago what kind of solutions regulatory and efficient measures could have been done to solve what, currently, it seems that can no longer be fixed.
