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. Continue reading
XR protesters getting carried away. Image: Facundo Arrizabalaga/EPA.
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? Continue reading
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

Did you know women are more likely than men to be affected by climate change? UN figures indicate that 80% of people displaced by climate change are women. And in light of the recent strikes by children across the world, it is clear that it is the most pressing issue for a lot of children around the world. So then, what role do mothers play in guiding and supporting our children in a changing climate? And what is it like to know the dangers of climate change and bring up a child in an uncertain world? 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
The international community has widely acknowledged the severe threats posed by the impacts of climate change to a series of human rights, including the rights to life, health, and an adequate standard of living. But a stark gap has emerged between this acknowledgement in global climate policy – evidenced by a non-binding clause in the preamble of the Paris Agreement – and their actions to meet promised targets. Continue reading
If we have to feed 9.8 billion people by 2050, food from the ocean will have to play a major role. Ending hunger and malnutrition while meeting the demand for more meat and fish as the world grows richer will require 60% more food by the middle of the century.
But around 90% of the world’s fish stocks are already seriously depleted. Pollution and increasing levels of carbon dioxide (CO₂) in the atmosphere, which is making the oceans warmer and more acidic, are also a significant threat to marine life. Continue reading
The effects of climate change vary hugely across political borders, and have wide-ranging impacts on different communities and environments. Climate policy responses must recognize this global interconnectedness, and integrate international cooperation with effective local action. This is why global treaties such as the Paris Agreement are so important in the fight against climate change, but individual nations must also do their bit to achieve the objectives set out in the agreement. In Environments without Borders (part of Research Without Borders), a panel debate hosted by Bristol Doctoral College and the Cabot Institute on Wednesday 10th May, we will discuss some of these issues, using examples from our research on particular challenges facing our global ocean and water environments.
