New Form of Carbon That’s Hard as a Rock, Yet Elastic, Like Rubber
Visualization of ultrastrong, hard and elastic compressed glassy carbon. A team including several Carnegie scientists has developed a form of ultrastrong, lightweight carbon that is also elastic and electrically conductive. A material with such a unique combination of properties could … Continue reading

A Massive Lake of Molten Carbon The Size of Mexico is Discovered Under The US
Scientists uncovered a huge reservoir of molten carbon situated under the Western US, 217 miles (350km) beneath the Earth’s surface Situated under western US, 217 miles (350km) beneath the Earth’s surface Upper mantle could contain up to 100 trillion metric … Continue reading
Early organic carbon got deep burial in mantle
Petrologists who recreated hot, high-pressure conditions from 60 miles below Earth’s surface have found a new clue about a crucial event in the planet’s deep past. Geology News — ScienceDaily
Study: Early organic carbon got deep burial in mantle
This schematic depicts the efficient deep subduction of organic (reduced) carbon, a process that could have locked significant amounts of carbon in Earth’s mantle and resulted in a higher percentage of atmospheric oxygen. Based on new high-pressure, high-temperature experiments, Rice … Continue reading
Future carbon dioxide, climate warming potentially unprecedented in 420 million years
Over the next 100 to 200 years, carbon dioxide concentrations in the Earth’s atmosphere will head towards values not seen since the Triassic period, 200 million years ago. Furthermore, by the 23rd century, the climate could reach a warmth not … Continue reading
