NASA recently announced that it is seeking new ways to complete the return to Earth of rock cores drilled by the Perseverance Rover in the Jezero Crater on Mars. This has led to some anxiety among space scientists, who view ...
Black carbon (BC) is the result of incomplete combustion of fossil fuels and biomass, with strong light absorption. It is second only to carbon dioxide as a climate-forcing factor for atmospheric warming. Deposition of BC ...
In a study published in Science Advances, scientists have used new lithium isotope (δ7Li) data to show that continental clay export promoted organic carbon burial and thus atmospheric oxygenation during the Cambrian period.
We all know Earth is special, but we may not fully appreciate how good we have it on this planet. Unlike its planetary neighbors, Earth has remained habitable for billions of years thanks to a complicated, ever-changing dance ...
Many artists have tried to depict what Earth might have looked like billions of years ago, before life made its appearance. Many scenes trade snow-covered mountains for lava-gushing volcanoes and blue skies for lightning ...
The present solid Earth is actually active, with new plates generating in the mid-ocean ridges and some old plates sinking back into the interior through subduction zones. Subduction is thus a key process of the tectonics ...
A large find of dinosaur tracks and fossilized plants and tree stumps in far northwestern Alaska provides new information about the climate and movement of animals near the time when they began traveling between the Asian ...
Massive volcanic events in Earth's history that released large amounts of carbon into the atmosphere frequently correlate with periods of severe environmental change and mass extinctions. A new method to estimate how much ...
A team of researchers from the University of Massachusetts Amherst that specializes in accounting for the carbon dioxide release by streams, rivers and lakes has recently demonstrated that the chemical process known as "carbonate ...
Anoxic marine basins may be among the most viable places to conduct large-scale carbon sequestration in the deep ocean, while minimizing negative impacts on marine life. So say UC Santa Barbara researchers in a paper published ...
