A 50,000-year history of current flow yields new climate clues
From 50,000 to 15,000 years ago, during the last ice age, Earth's climate wobbled between cooler and warmer periods punctuated by occasional, dramatic ice-melting events.

Aluminum may affect climate change by increasing ocean's carbon sink capacity
Reducing net greenhouse gas emissions to zero as soon as possible and achieving "carbon neutrality" is the key to addressing global warming and climate change. The ocean is the largest active carbon pool on the planet, with ...

New indicator for oxygen levels in early oceans developed
Oxygen is essential for the development of higher life. However, it was hardly present in the oceans of the young Earth. It was not until the evolution of photosynthetic bacteria that the oceans saw a significant increase ...

A deep reservoir of primordial helium in the Earth
Noble gases, including helium, neon, and argon, are characterized by high chemical inertness which causes low reactivity with other materials and high volatility. Among them, 3He, 20Ne, and 36Ar are particular isotopes which ...

Despite lower sulfur emissions in U.S. and Western Europe, air pollution is dropping more slowly
The air in the United States and Western Europe is much cleaner than even a decade ago. Low-sulfur oil standards and regulations on power plants have successfully cut sulfate concentrations in the air, reducing the fine particulate ...

Strange isotopes: Scientists explain a methane isotope paradox of the seafloor
Methane, a chemical compound with the molecular formula CH4, is not only a powerful greenhouse gas, but also an important energy source. It heats our homes, and even seafloor microbes make a living of it. The microbes use ...
