Applying a coat of paint on the walls of a house may soon help to heat it, saving energy and reducing CO2 emissions. It could also clean the air that we breathe, breaking down chemicals and pollutants, and eliminating harmful pathogens. In Europe, half of cities’ annual energy consumption goes to heating and cooling. Despite the EU’s … Read more

Genetics could explain how traumatic events affect people’s health

There could be a genetic explanation for why some people are more susceptible to ill health following traumatic life events such as a natural disaster. Image credit - Pfc. Nicholas T. Howes, USMC

by Kelly Oakes Facing the death of a loved one, being given a life-threatening diagnosis, or living through a natural disaster is difficult enough. But those who get through these traumatic life events often face further ill effects. Someone’s chances of developing post-traumatic stress disorder (PTSD), depression, and anxiety all increase after being exposed to significant … Read more

Studying Asian glaciers provides glimpse into future of extremes

The region of High Mountain Asia, which includes the Karakoram mountain range, is known as the third pole of the Earth because of the scale of its ice fields. Image credit - Tahakhan021, licensed under CC BY-SA 4.0

Scientists may have solved a 25-year-old puzzle about the mysterious behaviour of certain glaciers in High Mountain Asia. In most of this region, they are shrinking; but in the northwest, they are growing. High Mountain Asia includes ranges that span the borders of Afghanistan, Bhutan, Nepal, India, China and Pakistan. The rate of glacier melting … Read more

Trees and doodlebugs emit methane – the question is, how?

Trees and insects may play a significant role in the emission of methane – a potent greenhouse gas – and improving our understanding of exactly how this happens could help in targeting more effective ways to fight global warming. Because methane has more than 80 times the global warming potential of carbon dioxide over 20 years, … Read more

‘Most ice on Earth is very close to melting conditions’

Even if we change our emissions now, we are committed to a lot of ice melt, says Prof. Kääb. Image credit - Sharada Prasad CS, licensed under CC BY 2.0

We need to understand how glaciers are shrinking in order to better adapt to climate change impacts such as changes to water supply, landslides and avalanches, says Professor Andreas Kääb, a glacier expert from the University of Oslo in Norway.  Measuring ice melt and the unprecedented changes in our cryosphere – the frozen parts of … Read more
