Many people like to say that the coronavirus is teaching us a lesson, as if the pandemic were a kind of morality play that should lead to a change in our behaviour. It shows us that we can make big shifts quickly if we want to. That we can build back better. That social inequality is starkly revealed at times of crisis. That there is a “magic money tree”. The idea that crisis leads to change was also common during the financial crunch over a decade ago, but that didn’t produce any lasting transformations. So will post-COVID life be any different?
At the start of lockdown, in the middle of the anxiety and confusion, I started to notice that I was enjoying myself. I was cooking and gardening more; the air was cleaner, my city was quieter and I was spending more time with my partner. Lots of people started to write about the idea that there should be #NoGoingBack. It seemed that we had taken a deep collective breath, and then started to think about coronavirus as a stimulus to encourage us to think how we might address other big issues – climate, inequality, racism and so on.

How much greenhouse gas is emitted by any individual country? With global emissions of carbon dioxide hitting a record of 36.8 billion tonnes this year, and delegates gathering in Madrid for the latest UN climate talks, it’s a pressing question.
One might assume that we know precisely how much is emitted by any given country, and that such figures are rigorously cross-checked and scrutinised. And in some respects, this is true – countries are required to report their emissions to the UN, based on exhaustive guidelines and with reams of supporting data.
Yet these reports are based on what are known as inventory (or “bottom-up”) methods. To simplify, this means that governments figure out how much greenhouse gas is emitted by a typical car, cow, or coal plant, and then add up all the cows, cars and so on to get an overall emissions figure.

With BBC Panorama questioning if airlines are doing enough to go green, the University of Bristol We are Engineering blog asked Bristol’s engineers how they’re making aviation greener. We republish a shortened version below.
Viewers of BBC’s Panorama programme Can Flying Go Green? last week would have seen how our passion for flying is warming the planet. Aviation is a major contributor to global carbon dioxide emissions, burning more fossil fuels per passenger than any other form of transport. In the show, Justin Rowlatt investigates how the airlines are trying to clean up their act, but what is being done outside of the commercial sector to make aviation greener? Here’s what our engineers are doing to pave the way to a greener future for the industry. Continue reading →

The Arctic is one of the most rapidly changing regions on Earth. Its lands and oceans are undergoing unprecedented transitions, from permafrost melting to sea ice thinning, and its people are vulnerable to the knock-on effects of climate change. Continue reading →
Water is essential for human life, but in many parts of the world water supplies are under threat from more extreme, less predictable weather conditions due to climate change. Nowhere is this clearer than in the Peruvian Andes, where rising temperatures and receding glaciers forewarn of imminent water scarcity for the communities that live there. Continue reading →
The recent collapse of a bridge in Grinton, North Yorkshire, raises lots of questions about how prepared we are for these sorts of risks. The bridge, which was due to be on the route of the cycling world championships in September, collapsed after a month’s worth of rain fell in just four hours, causing flash flooding.

After occupying parts of central London over two weeks in April, Extinction Rebellion’s (XR) summer uprising has now spread to Cardiff, Glasgow, Leeds and Bristol. All these protests involve disruption, breaking the law and activists seeking arrest.
Emotions are running high, with many objecting to the disruption. At the same time, the protests have got people and the media talking about climate change. XR clearly represents something new and unusual, which has the power to annoy or enthuse people. But what led it to adopt such disruptive tactics in its efforts to demand action on climate change?

Antarctica is further from civilisation than any other place on Earth. The Greenland ice sheet is closer to home but around one tenth the size of its southern sibling. Together, these two ice masses hold enough frozen water to raise global mean sea level by 65 metres if they were to suddenly melt. But how likely is this to happen? Continue reading →
Hidden in even the clearest waters of the ocean are clues to what’s happening to the seas and the climate on a global scale. Trace amounts of various chemical elements are found throughout the seas and can reveal what’s going on with the biological reactions and physical processes that take place in them. Continue reading →
