Dating these rocks gives scientists evidence of when oxygen first built up in the atmosphere. Fossils Life processes can change the composition of the atmosphere. Fossils can tell scientists what ...

In particular, the varied, vertically resolved composition may significantly change the atmospheric function and lifetime of particles, resulting in corresponding impacts on climate. This research ...

Organisms may express both behavioral and physiological changes to atmospheric composition, resulting in large-scale and long-term responses of animal populations ranging from reduced genetic ...

We know that the composition of the Earth's atmosphere has changed over time, and that it is changing now. It is important for us to understand what effect climate change might have on life on our ...

We are pioneering a new field of study that will use micrometeorites, grains of cosmic dust, to investigate how the composition of Earth’s atmosphere has changed over time. We will use this novel ...

What causes glaciers to form in the first place? Scientists say changes in atmospheric composition or fluctuations in Earth's orbit and spin axis are the most likely triggers. 700 mya: Breakup of ...

Scientists have discovered that the Earth’s atmosphere is getting better at removing air pollution, including methane, one of the most powerful greenhouse gases. This new research, published in Nature ...
