The carbon dioxide level in the environment nowadays is likely more than what has been in the previous 3 million years. This increase in the carbon dioxide level, the greenhouse gas, could bring the temperatures not seen in the whole timespan, as per the new study.
The researchers of study utilized the computer model to look at the alterations in the climate amid the Quaternary time frame, which began about 2.59 million years prior and proceeds till today. In that period, the Earth has experienced various changes, however, none as quick as those happening today stated the author of study Matteo Willeit, the postdoctoral researcher on climate at the Potsdam Institute for the Climate Impact Research.
Willeit stated, “To get the climate hotter than the present-day, you essentially need to return to an alternate geological time frame.”
The sudden alteration in the climate was quite often exceedingly dangerous for life on Earth that was seen in the past, causing mass extinction, for example, end of the Triassic, Permian, or even the mid-Cambrian timeframe. The indications from those occasions (a major, fast hop in worldwide temperatures, the increasing level of seawater, and also the acidification of ocean) are altogether happening presently with the human-caused changes in climate.
Willeit said those discoveries are critical for understanding the state that decided if regions like Chicago or the New York City will be livable or will be canvassed in ice a mile high. But at the same time, they’re valuable for encircling the present climate change.
Willeit said, “It clearly demonstrates that regardless of whether you take a gander at past climatic conditions over exceptionally long timescales, what humans are doing at present in terms of the change in climate is something important and extremely quick, contrasted with what occurred in the past.”
The power of climate change appears to probably make totally new survival challenges for the species on our planet, which include humans and numerous different life forms also.
