University of Southampton scientists investigating ways of removing carbon dioxide (CO2) and other greenhouse gases from our atmosphere believe volcanic ash could play an important role.

A team from the University’s School of Ocean and Earth Science has modelled the impact of spreading volcanic ash from a ship to an area of ocean floor to help amplify natural processes which lock away CO2 in the seabed. They found the technique has the potential to be cheaper, technologically simpler and less invasive than other techniques to remove harmful gases.
The researchers’ findings are published in the journal Anthropocene.
Human-caused climate change is one of the most pressing topics in contemporary science and politics. The impact of hundreds of years of greenhouse gas emissions are becoming clearer every year, with environmental changes including heatwaves, droughts, wildfires, and other extreme weather events.
“As a result of overwhelming evidence, politicians

Sept. 24 (UPI) — The presence of tiny crystals in magma can cause volcanoes to violently explode, according to a new study published Thursday in the journal Science Advances.
“Exactly what causes the sudden and violent eruption of apparently peaceful volcanoes has always been a mystery in geology research,” lead researcher Danilo Di Genova said in a news release.
“Nanogeoscience research has now allowed us to find an explanation. Tiny crystal grains containing mostly iron, silicon, and aluminium are the first link in a chain of cause and effect that can end in catastrophe for people living in the vicinity of a volcano,” said Di Genova, a geophysicist at the University of Bayreuth in Germany.
Using a combination of spectroscopic and electron microscopic imaging techniques, researchers were able to identify nano-sized crystals called nanolites in the ashes of active volcanoes.
In the lab, scientists successfully demonstrated how these tiny crystals,

Researchers have discovered 125-million-year-old dinosaur fossils that are perfectly preserved and suggest the creatures were trapped by a volcanic eruption.
The study, published in the scientific journal PeerJ, notes the species were discovered in the western Liaoning Province in China and have been named Changmiania liaoningensis, which means “eternal sleeper from Liaoning” in Chinese.
“These animals were quickly covered by fine sediment while they were still alive or just after their death,” said the study’s co-author and paleontologist Pascal Godefroit, in a statement.

LARGEST DINOSAUR EVER HAD ‘RHINO-LIKE HORN’ AT BIRTH, RESEARCH REVEALS
C. liaoningensis was small compared to its larger herbivore brethren, such as the titanosaur. It was approximately 4-feet long and had “very powerful hind legs” to go with a long tail, which suggests the ancient ornithopod was a strong
