First evidence that Antarctica’s thinning ice shelves are causing more ice to move from the land into the sea

A detailed view of changes in ice flow around the Pine Island and Thwaites glaciers, due to thinning ice shelves. Pine Island Glacier is at the top right, with changes seen almost 100 miles inland.

New evidence suggests a huge asteroid DID hit EARTH 12,800 years ago causing an ice age

A huge asteroid may have hit the Earth 12,800 years ago causing global climate change and extinction, according to new evidence found in South Africa.Scientists analysed ancient soil at a site called Wonderkrater and found high levels of platinum – which they say supports the The Younger Dryas Impact Hypothesis that a disintegrating meteor hit Earth…

Microscopic evidence sheds light on the disappearance of the world’s largest mammals

A new article, published in BioScience, emphasizes contributions from five different approaches: radiocarbon dating, stable isotope analysis, ancient DNA, ancient proteins, and microscopy. These techniques can offer robust, high-resolution insights into climate change and extinction chronologies, past habitat transformations, ecological relationships, and species diet and ranging.

Earliest evidence of milk consumption

Image copyright Sophy Charlton / Dorset County Museum Image caption The evidence comes from dental plaque from Neolithic remains Scientists have discovered the earliest direct evidence of milk consumption by humans.The team identified milk protein entombed in calcified dental plaque (calculus) on the teeth of prehistoric farmers from Britain.It shows that humans were consuming dairy…

Astronomers Find Evidence for Volcanic Moon Orbiting Jupiter-Like Exoplanet WASP-49b | Astronomy -News.com

A volcanically active rocky exomoon may orbit WASP-49b, a hot gas giant approximately 550 light-years away in the constellation of Lepus. An artist’s impression of an exo-Io undergoing extreme mass loss. The hidden exomoon is enshrouded in an irradiated gas cloud shining in bright orange-yellow, as would be seen with a sodium filter. Patches of…

Over 250 Archaeologists Show Evidence Humans ‘Transformed’ Earth Long Before 1900s

BEN MARWICK & ERLE C. ELLIS, THE CONVERSATION 30 AUG 2019 Examples of how human societies are changing the planet abound – from building roads and houses, clearing forests for agriculture and digging train tunnels, to shrinking the ozone layer, driving species extinct, changing the climate and acidifying the oceans. Human impacts are everywhere. Our…
