A new study, recently published in the journal Science Advances reveals the smoke particles trapped in the ice.
These smoke particles tell about the fiery past that might have happened in the past in the Southern Hemisphere. This thing further puts light on the future due to climatic changes.

A student from Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) said that the idea about fire in the past atmosphere is not well characterized and hence the smoke in pre-industrial time is not revealed clearly.

He further added that these results are quite important to understand the concept of climate change from the year the 1750s till now and will also help to predict future climatic changes.

One of the biggest threats to the near future in terms of climate is the increasing global temperature and greenhouse gases.
The earlier predictions are quite difficult since understanding the warming and cooling of Earth takes lots of effort.

The greenhouse gases have the potential to capture the aerosols released by combustible materials, fire, or even from volcanoes and they further increase the temperature of the atmosphere.

The recent findings say that the levels of greenhouse gases in the pre-industrial era are well documented but the number of aerosols that were present in that era is not documented.

So, scientists wanted to create a model that could be used to estimate the number of aerosols present in the pre-industrial era in the atmosphere.

The scientists looked for the ice trapped smoke particles in Antarctica which might have come from Australia, Africa, or South America’s fire.
Smoke soot’s deposited in the ice is well preserved for the long-term data as they reveal the concentration of aerosols present in the atmosphere in a pre-industrial era.

But the results turned to be very surprising. It was assumed that the smoke would be in less concentration in the pre-industrial era but in return, the ice cores depict that history had more fire particularly in the southern hemisphere.
