European climatologists have discovered that the average temperature in central Greenland has increased over the past two decades by 1.5 degrees Celsius compared to its average value in the 20th century, according to the Russian news agency Tass.
And the media office of the German “Alfred Wegener Institute” stated that this matter indicates the beginning of the melting of the ice cover of the island, while Maria Horhold, a researcher at the institute, says, “We have followed how the climate has changed in the central and northern regions of Greenland over the past thousand years. Analysis of the data we collected clearly showed that the warming over the years 2001-2010 differed significantly from all natural climate changes over the entire previous millennium. We were surprised by how obvious the consequences of global warming are,” she says.
It is worth noting that, from a study of 16 samples of Greenland ice taken from different regions in the center of the island, Horhold and her colleagues discovered the first evidence that global warming began in recent decades affecting the coldest areas of central and northern Greenland. While the researchers confirm that these samples were formed over a period of more than a thousand years, which allowed the study of climate changes in central Greenland during the years 1000-2010.
To do this, the researchers measured the number of atoms of the two stable isotopes of oxygen, oxygen-16 and oxygen-18, present in the annual ice layers in each sample, as the ratios of these isotopes reflect the temperature that was during the deposition of the island’s ice sheet. The results of the calculations showed that the usual temperatures did not increase in Greenland, but rather decreased during the period studied. But this situation changed at the end of the nineteenth century; As temperatures in Greenland began to rise gradually. At the beginning of the twentieth and twenty-first centuries, there were drastic changes in the climate of the central regions of the island, when the average temperature increased by 1.5 degrees Celsius during a very short period of time. This indicates, according to the researchers, that global warming is affecting all regions of Greenland, which may lead to melting of the ice sheet during the coming years and decades.
