The current energy crisis has re-energised conversations around the switch to renewable resources. Solar panels are one of the options, so in this month’s edition of Periodic Graphics in Chemical & Engineering News, we take a look at how these panels generate electricity and some of the present and potential materials used in them.

The 2021 Nobel Prize in Physics: Climate modelling and understanding complex systems

Infographic on the 2021 Nobel Prize in Physics. The winners demonstrated the effects of carbon dioxide in Earth's atmosphere on Earth's surface temperatures, provided mathematical climate models that informed those in use today, and allowed us to identify and compare the impact of human and natural processes on Earth's climate. They also showed that, in complex systems, things which appear random are still subject to complicated hidden rules.

The 2021 Nobel Prize in Physics was awarded to Syukuro Manabe and Klaus Hasselmann “for the physical modelling of Earth’s climate, quantifying variability and reliably predicting global warming”, and to Giorgio Parisi “for the discovery of the interplay of disorder and fluctuations in physical systems from atomic to planetary scales.”

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.

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 even hundreds of thousands of years ago? There is, of course, no written record that far back in history – but there is a chemical record, hidden in the ice of Antartica and Greenland.
