First came the surprising discovery that Earth’s atmosphere is leaking. But for roughly 60 years, the reason remained a ...

Carbon dioxide (CO2) has been present in the atmosphere since the Earth condensed from a ball of hot gases following its formation from the explosion of a huge star about five billion years ago.

The atmosphere is a mixture of gases. The atmosphere is mostly nitrogen (approximately 80%) and oxygen (approximately 20%). The remaining gases are found in much smaller proportions, such as ...

Since the Industrial Revolution began, that totals nearly 1,000 metric gigatons stuck in the atmosphere. Now, scientists are working around the clock to create all sorts of new, innovative ...

This image of our planet is the closest we get to a real-time view of how carbon dioxide builds up in our atmosphere. Jan. 1 CO2 emitted by: Fossil fuels Fire Land Ocean Loading data ...

Cosmic dust steadily rains down onto Earth's atmosphere, while the odd kilometer-size asteroid meandering through space will find its way to Earth every few hundred million years or so.

Although nitrogen is very abundant in the atmosphere, it is largely inaccessible in this form to most organisms. This article explores how nitrogen becomes available to organisms and what changes ...

Human activities have been the main cause of rising carbon dioxide levels in our atmosphere since the 1800s. The emergence of life on our planet added a new layer to the carbon cycle. As plants grow, ...

According to a 1998 study by MIT climatologist Kerry Emanuel, Milton is nearing the upper limits of what Earth’s atmosphere can generate with a hurricane in the Gulf of Mexico or the Atlantic Ocean.

Carbon, a building block of life, is constantly moving through different environmental compartments such as biota, the atmosphere, the ocean, soil and sediment, as part of what is called ‘the global ...
