Study: Near-surface permafrost will be nearly gone by 2100

September 15, 2023 – Most of Earth’s near-surface permafrost could be gone by 2100, an international team of scientists has concluded after comparing current climate trends to the planet’s climate 3 million years ago. The team found that the amount of near-surface permafrost could drop by 93% compared to the preindustrial period of 1850 to […]

Research reveals sources of CO2 from Aleutian-Alaska Arc volcanoes

Scientists have wondered what happens to the organic and inorganic carbon that Earth’s Pacific Plate carries with it as it slides into the planet’s interior along the volcano-studded Ring of Fire.
