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.
As wind turbines become increasingly familiar sights along shorelines, developers of offshore floating platforms, which harness the powerful winds further out to sea, are seeking to establish their technologies as a major viable source of clean energy.
Bill Gates and the European Commission have launched a €100 million investment fund designed to bring radical clean energy technologies more quickly to market in order to promote energy efficiency and cut greenhouse gas emissions.
Hydrogen can be used to power cars, supply electricity and heat homes, all with zero carbon emissions. The snag is that the vast majority of hydrogen itself is derived from fossil fuels – a fact that scientists are now hoping to change. They plan to clean up production to kickstart a dedicated economy – something that has already found small-scale success in Scotland’s Orkney Islands.
We should breed new varieties of crops based on their root architecture rather than just focusing on the top half of the plant, according to scientists looking at how to cultivate plants that use water more efficiently and better withstand drought conditions.
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.
The most cost-effective climate change actions are also those that could help us achieve sustainable development goals (SDGs) such as ending poverty and hunger, according to Dr Keywan Riahi, director of the energy program of the International Institute Applied Systems Analysis (IIASA) in Austria, who says the first step should be to cut our energy demand.
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.
From about 245 to 66 million years ago, dinosaurs roamed the Earth. Although well-preserved skeletons give us a good idea of what they looked like, the way their limbs worked remains a bigger mystery. But computer simulations may soon provide a realistic glimpse into how some species moved and inform work in fields such as robotics, prosthetics and architecture.
Award-winning energy scientist says we need to change tack.
Study shows that melt is independent from Arctic sea ice loss.
With environmental changes locked in for several decades, are we too late to save the Arctic?
