An international team of scientists used dripstones from globally distributed caves together with model simulations to analyze the global impacts of rapid Northern-Hemisphere temperature increases, the widely studied Dansgaard-Oeschger events, that repeatedly occurred during the last ice age. The comparison of stalagmite and model data shows in unprecedented detail how these abrupt changes and the associated modifications of the Atlantic overturning circulation, AMOC for short, have affected global atmospheric circulation.

Using stalagmites in the European Alps, they were able to demonstrate that warm phases appeared primarily when the summer insolation reached maxima in the Northern Hemisphere.

New indications show that oscillations between extreme wetness and aridity in California were closely linked with the occurrence of wildfires. The researchers have concluded that such events are likely to become more common in the face of human-induced climate change.

Caves have also intrigued scholars from early Chinese naturalists to Charles Darwin. A cave ecologist has been in and out of these subterranean ecosystems, examining the unique life forms -- and unique living conditions -- that exist in Earth's many caves. But what does that suggest about caves on other planetary bodies? In two connected studies, engineers, astrophysicists, astrobiologists and astronauts lay out the research that needs to be done to get us closer to answering the old-age question about life beyond Earth.

Central Asia is positioned at a crossroads linking several zones important to hominin dispersal during this period, however much evidence from this region lacks context for dating and climate conditions, making it difficult to understand these dynamics.

A research team has been working on reconstructing the climate history of this region in this extremely wet, rainy and inaccessible fjord and island zone of the Patagonian Andes in southern Chile.

More than 5000 years ago, the city already had an elaborate water management system. Until now, it has been controversial what led to the sudden collapse. Massive flooding triggered by anomalously intense monsoon rains caused the collapse, as geologists and climate researchers have now shown. 结婚,2021年11月24日15:38:13 EST //www.koonmotors.com/releases/2021/11/211124153813.htm //www.koonmotors.com/releases/2021/11/211118203623.htm Researchers have now reconstructed how the Indian summer monsoon responded to meltwater pulses into the North Atlantic at the end of the penultimate cold period.

They devised a statistical method to determine whether these transitions are simply noise or evidence of a more significant change. Their method is less error-prone than previous methods, since it doesn't rely on human determination. It also allows comparing different records consistently and can identify important events that may have been overlooked in older studies.

A few fish, like Mexican cavefish, have evolved in unique environments without any predators. To see how this lack of predation impacts escape responses that are highly stereotyped across fish species, scientists explored this tiny fish to determine if there are evolved differences in them. Findings reveal that the dramatic ecological differences between cave and river environments contribute to differences in escape behavior in blind cavefish and river-dwelling surface cavefish.

Researchers describe a new species of cave-dwelling, insect-like dipluran from the island of Vancouver (Canada) and discuss its origin.

They also determined that an already known salamander species near Georgetown is much more endangered than previously thought. They warn that more severe droughts caused by climate change and increasing water use in Central Texas have left groundwater salamanders 'highly vulnerable to extinction.'

This finding suggests there are gaps in the fossil record, potentially obscuring evolutionary patterns and affecting our understanding of both the habitats and dietary behaviors of early hominins in this region. South Africa's highest concentration of early hominin fossils comes from the 'Cradle of Humankind' caves northwest of Johannesburg.
