It has been revealed through a recent report published in Nature that the increase in atmospheric CO2 is being seen as the result of the warming in climate, as per a team of researchers from the Oregon State University.

According to the report findings, the atmospheric concentration of carbon dioxide has significantly increased over a long period of 7,000 years. While previously it was about 180 parts per million, it has now reached up to 260 ppm. It is being said that the rising of carbon followed warming in temperature was last seen during ending of the last Ice Age.

The report says that the Ice Age ending had happened due to warming only. However, initially it was believed to be due to change in the wobble of Earth’s axis. But, later it was found that CO2 had accelerated the process.

A study was carried out by the researchers in collaboration with those from Harvard University and some other institutes in China, America and France. The collaboration had visited around 80 sites to take ice core samples and underwater sediment, all of which led them to conclude that CO2 is the only cause of big melt.

On the contrary, some sources have been claiming that warming is always caused because of mount in CO2. It has also told that the only spot where an opposite case has been seen is Antarctica.

“An antiphased hemispheric temperature response to ocean circulation changes superimposed on globally in-phase warming driven by increasing CO2 concentrations is an explanation for much of the temperature change at the end of the most recent ice age”, affirmed a source.

But, it is being claimed by the lead author of the study, Jeremy Shakun that no matter what the reason, carrying up of a further 100 ppm could be ended up by the end of this century.
