Researchers found that short interstadials trigger a northward leap of the Westerlies, facilitating near-source moisture transport and suppressing δ18O depletion. The study provides new insights into the complex dynamics behind abrupt climate changes.
A study using stalagmite analysis found eight wet season droughts lasting over three years between 871-1021 CE, contributing to the Maya civilization's decline. This climate data aligns with historical and archaeological evidence, providing a new framework for analyzing human-climate interactions.
Researchers have precisely dated the devastating Laacher See volcano eruption in Central Europe, which did not cause a sudden-onset cold period 13,000 years ago. The study used speleothem and ice core data to estimate the climatic impact of the eruption.
Researchers from SapienCE Centre of Excellence use dripstones to study past climate in South Africa. They found that the region experienced highly variable rainfall and slightly warmer temperatures during a crucial time period for early human occupations.
A recent study by German and Austrian researchers used stalagmites to document the impact of summer insolation on ice age climate dynamics. The findings suggest that warm phases appeared primarily during peak Northern Hemisphere summer insolation, with model simulations confirming these results.
Researchers reconstruct relative sea level record from Mallorca island using phreatic overgrowths on speleothems, finding stability instead of fluctuations. This accurate record provides insight into future sea level rise due to global warming and challenges current estimates.
Researchers at University of Akron investigate high microbial communities in BIF caves, theorizing microbes use iron to respire and cause rust-like oxides to become soluble. This process could be responsible for voids forming within the cave walls, eventually leading to new cave formation.
Researchers found microbes actively contribute to dripstone formation, with layers mirroring seasonal changes. The discovery sheds light on the role of biological life in shaping Earth's geology and has implications for understanding microbial life beyond Earth.
A team of researchers has discovered the oldest human skeleton in North America, dating back 13,000-12,000 years. The skeleton, named Naia, was found in an underwater cave in Mexico and shows a shared genetic code with modern Native Americans.
Researchers have found evidence of a 1-meter high sea level stand around 81,000 years ago, contradicting previous estimates of low levels. This finding highlights the importance of natural sea level fluctuations and their potential impact on coastal populations.
Researchers discover new method for growing tiny tubes, similar to those found in caves and at hydrothermal vents. The discovery uses a controlled laboratory setup to replicate the formation process, allowing scientists to study it on human time scales.
