The researchers said this could mean global climate models, which expect soils to be a sink, may overstate the China wholesale hex nuts ability of terrestrial ecosystems to lessen the impacts of climate change. "So at least in Wyoming, my data suggests soils acted as a source, not a sink, for carbon dioxide, which could provide new information as we try to figure out where our climate is heading. However, additional studies are needed to see how soils reacted to the PETM in other parts of the world.Baczynski said, "The instrument she developed will help with similar fossil research and has boarder applications to study materials with low carbon levels, like extraterrestrial samples that could someday come from Mars.5 million years ago that's considered the best analog for modern climate change.She explained that, in the Bighorn Basin, it appears that high PETM temperature, seasonally intense precipitation, or a combination, accelerated organic matter decay rates such that they outpaced plant productivity and ultimately resulted in reduced soil organic carbon during the PETM.

Washington: According to an international team of scientists, rock core samples from a period of warming millions of years ago indicate soils contributed to a rapid rise in atmospheric greenhouse gas and suggest modern climate models may overestimate Earth's ability to mitigate future warming.According to the researchers, ancient soils from a site in modern-day Wyoming acted as a source of atmospheric carbon dioxide, emitting the greenhouse gas into the atmosphere, and not a sink, trapping and storing carbon underground."Baczynski spent parts of four years improving the sensitivity of the equipment by two orders of magnitude, and using that tool, the team collected the first biomarker record of the PETM from terrestrial core samples.".The findings were published by The Journal Paleoceanography and Paleoclimatology.Researchers discovered a drastic drop in organic material preserved in sections of core samples from the Paleocene-Eocene Thermal Maximum (PETM), a global warming event 55. "

We see the amount of carbon drops drastically, by orders of magnitude, during this PETM event," said Allison Baczynski, a postdoctoral scholar in geosciences at Penn State and lead author on the study.Scientists find clues on how soils may respond to climate change.5 million years ago that's considered the best analog for modern climate change.
