Underwater waves deep below the ocean’s surface – some as tall as 500 metres – play an important role in how the ocean stores heat and carbon, according to new research.

From toasters that won’t pop to farmers hacking their own tractors, we ask why the right to repair is important for people and for the planet – and we visit a local Repair Café to meet some of the 'fixers' in action.

A team of student entrepreneurs who see algae as a potential business solution for reducing methane emissions from landfill and waste-water sites won the 2023 Cambridge Zero Climate Challenge after a nail-biting competition. 

Cambridge Zero Director Professor Emily Shuckburgh, King Charles and Natural England Chair Tony Juniper have co-authored a new book on climate change written for children.

Researchers from the ̽��ֱ�� of Cambridge have analysed more than 800,000 tweets and found that negative emotions expressed about geoengineering – the idea that the climate can be altered using technology – can easily fall into conspiracy.

Researchers have calculated the carbon footprint for the full life cycle of fertilisers, which are responsible for approximately five percent of total greenhouse gas emissions – the first time this has been accurately quantified – and found that carbon emissions could be reduced to one-fifth of current levels by 2050.

As the climate emergency and cost-of-living crisis focus our minds on how to reduce energy, a group of scientists have highlighted the hidden environmental cost behind some of our major breakthroughs.

Researchers have developed a system that can transform plastic waste and greenhouse gases into sustainable fuels and other valuable products – using just the energy from the Sun.

Air travel is one of the major contributors to global warming. Cambridge scientists are working with leading energy companies to help develop sustainable aviation fuels, which could reduce the industry’s carbon emissions by up to 80%.

In the week of COP27 people across the world have flown to Sharm El Sheikh to discuss action on climate change. Aviation is a crucial way to bring us together to tackle this challenge – but it is also a major contributor to the problem.
