A team has reviewed the literature on the internal and external mechanisms that lead to a volcanic eruption. Analyzing the thermo-mechanics of deep volcanic processes and magma propagation to the surface, together with magma chemistry, the geologists determined that most of the magma rising from depth actually does not cause a volcanic eruption. They also … Analysing volcanoes to predict their awakening
Researchers found a direct link between global dispersion of nickel-rich aerosols, ocean chemistry changes and the end-Permian mass extinction event that took place 251 million years ago.

The depths of the Black Sea store comparatively large amounts of organic carbon. A research team has now presented a new hypothesis as to why organic compounds accumulate in this semi-enclosed sea and other oxygen-depleted waters. Reactions with hydrogen sulfide play an important role in stabilizing carbon compounds, the researchers posit. This negative feedback in … Sulfur enhances carbon storage in the Black Sea
Ozone is a pollutant at ground level, but very high in the atmosphere’s ‘ozone layer,’ it absorbs damaging ultraviolet radiation. Past studies have examined ozone levels in the Southern Hemisphere, but little is known about levels of the molecule in Antarctica over long periods. Now, researchers have analyzed more than 25 years of Antarctic data, … Ozone pollution has increased in Antarctica
The analysis of very old plant fossils discovered in South Africa and dating from the Lower Devonian period documents the transition from barren continents to the green planet we know today.

For the first time, a unique study has tracked the meteorite flux to Earth over the past 500 million years. Contrary to current theories, researchers have determined that major collisions in the asteroid belt have not generally affected the number of impacts with Earth to any great extent. Title: Earth’s meteorite impacts over past 500 … Earth’s meteorite impacts over past 500 million years tracked
An international team of researchers has now succeeded in reconstructing changes in rainfall in Central Asia over the past five million years. The information preserved within the sedimentary succession provides the missing link for understanding land-water feedbacks for global climate. Title: Five million years of climate change preserved in one placeSourced From: www.sciencedaily.com/releases/2021/06/210603111951.htmPublished Date: Thu, … Five million years of climate change preserved in one place
Glaciologists analyzed Antarctic ice cores to understand the continent’s air temperatures during the most recent glacial period. The results help understand how the region behaves during a major climate transition.

New research finds that increases in monsoon rainfall over the past million years were linked with increases in atmospheric CO2 and the import of moisture from the southern hemisphere, which suggests stronger rains in the future as CO2 levels rise.
