Aerosol pollution typically makes clouds clouds more reflective, cooling the Earth. Evidence from the Arctic shows this cooling effect gets weaker as the Earth gets warmer, accelerating climate change.
We spend a lot of time at Imperial looking contrails. These are usually from passenger or cargo aircraft, but military aircraft also contrails, making them visible from space even when they are not publicly reporting their position.
Not only is the world a cloudy place, clouds are really common in TV and film. But do they behave like real clouds? Is the physics correct? Let's start with The Simpsons. Smoke make clouds rain? That's unpossible!
The Hunga Tonga eruption on the 14th of January 2022 was one of the largest volcanic eruptions in the modern satellite era. How tall with the resulting ash cloud, how did it change nearby clouds, and why is it a great reason to get a Nintendo 3DS?
COP26, the UN climate change conference, is in Glasgow this week. Clouds have a number of important roles to play in climate change. Let's start with number 1 - how does human activity change clouds and the climate?
Rivers are made of water, clouds are made of water, a natural match? It turns out there are fewer clouds over rivers because they are too wet!
Clouds created by aircraft (contrails) are responsible for a large amount of the warming from aircraft. How did they change during the COVID-19 shutdown and what does this tell us about the climate effect of aircraft?
Imagine you could change the properties the control a cloud, how quickly would the cloud respond?
Why are some clouds brighter than others in this timelapse sunrise over London?
