Researchers have been searching for climate change evidences for decades. With many predicting the change’s gearing up with industrial revolution in western countries, Earth’s climate seems to be repeatedly and dramatically shifting at a time period as short as a decade. Abrupt climate change seems to be more likely in the future.
To get to the roots of this global worrisome phenomenon, scientists are all set to venture new avenues, with recently equipping themselves with the ‘ancient marine fossils’ chemical composition’ as their research tool.
These tools have provided them with new evidence that greenhouse gases have a big impact on climate.
Relying on a study of rare clumps of oxygen and carbon isotopes bonding with each other, this new method uses all of the needed information stored in the fossil itself - especially the surface temperature at the time the animal lived.
This oxygen-carbon isotopes bonding varies with surface temperature — with more being formed at low temperatures and fewer at higher temperatures.
Thus, ancient fossils’ age can help scientists decode the then seawater temperature, they lived in — hence track the ever happening climate change.
