Researchers suggest that the Antarctic Ice Sheet partly reached its maximum thickness before the Last Glacier Maximum.

Around 650 million years ago, the Earth entered into the Marinoan glaciation that saw the entire planet freeze. The ‘Snowball Earth’ impeded the evolution of life. But as it warmed, biotic life began to flourish. A research team has now analyzed rock samples from China to tell us more about this transition. Title: Bacterial bloom … Bacterial bloom as the Earth thawed: Photosynthetic organisms during the Snowball Earth

A new analysis of 2.5-billion-year-old rocks from Australia finds that volcanic eruptions may have stimulated population surges of marine microorganisms, creating the first puffs of oxygen into the atmosphere. This would change existing stories of Earth’s early atmosphere, which assumed that most changes in the early atmosphere were controlled by geologic or chemical processes. Title: … Volcanic eruptions may have spurred first ‘whiffs’ of oxygen in Earth’s atmosphere

Scientists have discovered that extensive chains of volcanoes have been responsible for both emitting and then removing atmospheric carbon dioxide over geological time. This stabilized temperatures at Earth’s surface.

Ocean deoxygenation during the Mesozoic Era was much more rapid than previous thought, with CO2 induced environmental warming creating ocean ‘dead zones’ over timescales of only tens of thousands of years. The research paints a new picture of severe ocean deoxygenation events in our planet’s geologic history. Title: Volcanism drove rapid ocean deoxygenation during the … Volcanism drove rapid ocean deoxygenation during the time of the dinosaurs

The eastern half of the U.S is one of the principal hot spots for severe thunderstorm activity, especially tornadoes, globally. The standard explanation for this outcome is the combination high terrain to the west and the Gulf of Mexico to the south. A new study largely overturns one half of this longstanding hypothesis. Title: Would … Would we still have severe thunderstorms over North America if the Gulf of Mexico were filled in with land?

At certain sites in the Grand Canyon, more than one billion years’ worth of rocks have gone missing from the geologic record. Scientists are trying to figure out why.

The same phenomenon that causes aurorae — the magical curtains of green light often visible from the polar regions of the Earth — causes mesospheric ozone layer depletion, which could have significance for global climate change. Now, a group of scientists has observed, analyzed, and provided greater insight into this phenomenon. Title: Under the northern … Under the northern lights: Mesospheric ozone layer depletion explained
