It's not only nuclear bomb tests that disrupt the atmosphere, there are a number of natural events that can do the same. But how long does any damage last?
The Earth's magnetic field was most likely weaker when life evolved on our planet than it is today.
You might think the more oxygen you breathe in the better. But too much oxygen can make you sick.
Hurricane stalling has become common over the past half-century, and their average forward speed has also slowed.
Last week, much of the Midwest and eastern US experienced hazy skies and red sunsets. The cause was smoke transported from the Western US by the jet stream and spread as far as Boston and even Europe.
Clouds can act as both blanket and parasol – warming our atmosphere at the same time as cooling it. But which effect will dominate?
The man who explained the greenhouse effect was accidentally killed by his wife.
Carbon emissions are chilling the atmosphere 90km above Antarctica, at the edge of space
You might have already felt what it would be like inside a cloud made of condensed water vapor.
Atmospheres can be all different colours, depending on what's in them.
Not so long ago, people had no idea what would happen to them – and what they would see – once they ascended into the clouds.
More than 600 experts will spend the next year drifting in Arctic waters to gain a better understanding of how climate change is affecting the region and how it can be fought.
Carbon dioxide makes up less than one-twentieth of 1% of Earth's atmosphere. How does this relatively scarce gas control Earth's thermostat?
If the Amazon rainforest functions as our planet's lungs, what do raging wildfires threaten? An atmospheric scientist explains why the fires, though devastating, won't suffocate life on Earth.
It helps if you imagine the ground here on Earth as a big heater. It keeps us warm, and if you move away from the heater you feel cold.
An expert explains all the wonderful ways the atmosphere protects life on Earth.
It's hard to believe, but big storms and hurricanes are caused by tiny particles moving around in the atmosphere.
According to a new study, the oceans have absorbed more heat from climate change than previously thought. This could mean the Earth will warm even faster in the future than scientists have predicted.
Scientists studying the atmosphere found help in an unlikely place – the aerial bombing campaigns of World War Two.
Jupiter's bands are one of its most striking features – and can be seen from Earth – but they only go so deep within the giant planet. Now scientists think they know why.
