Governments at the COP24 climate change conference in Katowice, Poland, which ends on 14 December, should tackle fossil-fuel reliance by building a global energy grid that connects renewable energy from all around the world - and the best place to start is with a giant wind farm in Greenland, says Professor Damien Ernst, an energy scientist from the University of Liège, Belgium.
Melting sea ice, plastic waste, biodiversity loss – the Arctic is facing unprecedented environmental pressure and will continue to change until 2050 even if we meet targets to limit global warming, according to Marianne Kroglund from the Arctic Council, an intergovernmental forum addressing the challenges faced by Arctic governments and indigenous peoples.
Connecting objects and devices through the Internet of Things (IoT) can help solve the greatest challenges of our time, from cutting emissions to feeding a growing population, believes Alicia Asín, CEO and co-founder of Spanish technology company Libelium which makes IoT hardware. Asín was the second-place winner of the 2018 EU Prize for Women Innovators.
The technology to help limit global warming to 1.5˚C already exists, but there needs to be the will to use it, according to Kristin Jordal, an engineer and senior research scientist at the Norwegian research organisation Sintef.
To avoid climate breakdown, eliminating fossil fuels is the easy part, according to Professor Johan Rockström, co-director of the Potsdam Institute for Climate Impact Research in Germany. He says that safeguarding biological resources such as water, soil and biodiversity will be the ultimate test of whether global warming targets can be reached.
Businesses and consumers need to stop thinking of products as things to own and move towards a culture of sharing and repairing if we are to fulfil the ambition of creating a circular economy, according to Felipe Maya, project and innovation manager at sustainable engineering firm Exergy, headquartered in Coventry, UK.
Research suggests that where we live can affect our mental health but Dr Marco Helbich, an urban geographer at Utrecht University in the Netherlands, believes these studies only offer a limited snapshot of our lives. Using a smartphone app and register data, he is tracking people through their daily routines and their residential history to see whether mental health is affected by where we live, work and socialise. His findings could change how we design our cities.
A group of chemicals known as bi-metallics could help the pharmaceutical industry become more environmentally friendly by cutting the amount of energy used to produce drugs, according to Professor Eva Hevia from the University of Strathclyde, UK, who says that sustainability is a top priority for chemists.
One of the biggest drawbacks of electric vehicles – that they require hours and hours to charge – could be obliterated by a new type of liquid battery that is roughly ten times more energy-dense than existing models, according to Professor Lee Cronin, the Regius Chair of Chemistry at the University of Glasgow, UK.
Thawing ground sends carbon dioxide and methane into the atmosphere.
Award-winning energy scientist says we need to change tack.
With environmental changes locked in for several decades, are we too late to save the Arctic?
