Chemical Concerns Nuclear Power

Nuclear waste and its disposal

Today (22 April) is Earth Day. While currently, we’re somewhat preoccupied with a different crisis, the climate crisis remains a pressing concern. Nuclear power is an oft-mentioned alternative to fossil fuels but comes with the associated problem of nuclear waste. Here, Matthew Harris explains some of the storage solutions and puts the problem in perspective.

Today in chemistry history: The Kyoto protocol

On this day back in 2005, the world’s first legally-binding climate change agreement came into force. The Kyoto protocol, to which 192 countries are a party, aimed to reduce emissions of six greenhouse gases by 5.2% by 2012, relative to 1990. This graphic gives a brief overview of the agreement and the outcome of its […]

The science of ice cores: Atmospheric time machines

We know what global temperatures are like now, from direct measurement around the globe. And we know quite a lot about what temperatures were like over the past few hundred years thanks to written records. But what about further back than that? How do we know what temperatures were like a thousand years ago, or […]

Ocean Acidification: “The Other Carbon Dioxide Problem”

Ocean acidification is often referred to as ‘the other carbon dioxide problem’. We’re all quite rightly concerned about the effects that rising atmospheric carbon dioxide levels may have on climate, and the potential consequences of climate change are well documented: more frequent instances of extreme weather, and higher global average temperatures to name but two. […]

Ocean Acidification and Chemical Signalling

You might recall a month or so ago I started a new project on the site, Chemunicate, with which I aim to work with chemistry researchers and help produce graphics explaining their work in a straightforward manner. This graphic is the result of a collaboration with scientists from the University of Hull, and explains their study […]
