During the month of February, we are focusing on ‘Accessibility and Inclusivity’ here at the EGU. Although these topics are clearly relevant to the General Assembly, some people may wonder whether they also relate to scientific research. Clearly all geoscientists are people, so accessibility and inclusivity matter regardless of what scientific discipline they are in. But there can also be tangible ...[Read More]

2020 is being described by many as a tipping point: the year that humanity as a species must take concrete and measurable action to prevent catastrophic climate change. But even if we do manage to slow carbon emissions from 2020 onwards, how would the planet deal with all the carbon dioxide we have produced so far? How much capacity do the planet’s natural carbon sequestration reserves actually ha ...[Read More]

Geosciences Column: Taking a Breath of the Wild – are geoscientists more effective than non-geoscientists in determining whether video game world landscapes are realistic?

Are people with a geoscientific education better at telling ‘fake’ natural features in video games from real ones? A new study tested both geoscientists and non-geoscientists with photos of natural and artificial landscapes. (Photos from Rolf Hut et al. 2019)

For years, geoscientists have been both fascinated and perplexed by the beautiful (yet often inaccurate) landscapes present in several video games. But are people with a geoscientific education better at telling ‘fake’ natural features from real ones? Rolf Hut, an assistant professor at Delft University of Technology in the Netherlands, and his colleagues sought to answer this question in a new st ...[Read More]

Geosciences Column: How erupting African volcanoes impact the Amazon’s atmosphere

When volcanoes erupt, they can release into the atmosphere a number of different gases initially stored in their magma, such as carbon dioxide, hydrogen sulfide, and sulfur dioxide. These kinds of gases can have a big influence on Earth’s atmosphere, even at distances hundreds to thousands of kilometres away. A team of researchers have found evidence that sulfur emissions from volcanic eruptions i ...[Read More]
