How can we use meteorological models to improve building energy simulations?

Climate change is calling for various and multiple approaches in the adaptation of cities and mitigation of the coming changes. Because buildings (residential and commercial) are responsible of about 40% of energy consumption, it is necessary to build more energy efficient ones, to decrease their contribution to greenhouse gas emissions. But what is the relation with the atmosphere. It is two fold ...[Read More]

Academia is not the only route: exploring alternative career options for Earth scientists

With more PhD and postdoc positions than there are tenured posts, landing a permanent job in academia is increasingly challenging. For some, years of funding and position uncertainty, coupled with having to relocate regularly is an unwelcome prospect. A changing job market also means that aspiring to the traditional, linear career path might be an unrealistic expectation. Skills acquired by those ...[Read More]

The Venus enigma: new insights into ‘Earth 2’

Apart from Earth, there are a lot of Peculiar Planets out there! Every 8 weeks, we look at a planetary body worthy of our geodynamic attention. This week Richard Ghail, lecturer in Engineering Geology at Imperial College London in the United Kingdom, discusses Earth’s sister: Venus. Geologists have long held the view that they only have the results of one experiment: Earth. The growing list ...[Read More]

Image of the week – Learning from our past!

Understanding the climate evolution of our planet is not an easy task, but it is essential to understand the past if we are to predict the future! Historic climate cycles provide us with a glimpse into a period of time when the Earth was warmer than it was today. Our image of the week looks at these warmer periods of time to see what they can tell us about the future! For example, during the Plioc ...[Read More]

The Fractional Crystallization Freak Zone

The Fractional Crystallization Freak Zone

A large majority of igneous rocks on Earth are formed by a process known as fractional crystallization (summarized in the diagram below). To understand this process, start by imagining a large liquid magma (melt) body. As we cool the magma, mineral phases become stable and crystals start to form. The newly formed minerals are likely to have a very different density from the magma causing them to f ...[Read More]

GeoPolicy: What are European Commission Consultations and how can scientists contribute?

The European Commission requires both expert advice and an understanding of public opinion to steer policy and draft new EU legislation proposals that will be introduced to both the Council and the EU Parliament to debate. The EU Commission regularly hosts hearings, workshops, expert groups and consultations to gain valuable insights, prompt discussion and help draft policy.  These forums may be r ...[Read More]

NetherMod Day 3 – Karaoke fun!

Reporting live from the NetherMod karaoke bar,we summarise our experience with geodynamical karaoke (also see this post on the relationship between the two). Day 3 of NetherMod sizzled in a high of 29 °C, which meant the free afternoon just had to be that day. Of course, the day of the free afternoon had to round up with wine tasting and karaoke after dinner. How convenient that the wine tasting p ...[Read More]
