What? Ice lollies falling from the sky?

What? Ice lollies falling from the sky?

You have more than probably eaten many lollipops as a kid (and you might still enjoy them. The good thing is that you do not necessarily need to go to the candy shop to get them but you can simply wait for them to fall from the sky and eat them for free. Disclaimer: this kind of lollies might be slightly different from what you expect… Are lollies really falling from the sky? Eight years ago ...[Read More]

Black Carbon: the dark side of warming in the Arctic

Black Carbon: the dark side of warming in the Arctic

When it comes to global warming, greenhouse gases – and more specifically CO2 – are the most often pointed out. Fewer people know however that tiny atmospheric particles called ‘black carbon’ also contribute to the current warming. This post presents a paper my colleague and I recently published in Nature Communications . Our study sheds more light into the chemical make-up of black ca ...[Read More]

When cooling causes heating

When cooling causes heating

                          Following the Montreal Protocol in the late 1980s, CFC (chlorofluorocarbon) were replaced by hydrofluorocarbons (HFC) as a refrigerant. Unfortunately, the HFC’s have a global warming potential (GWP) far greater than the well-known greenhouse gas (GHG), carbon dioxide. Apart from the fact that this was not kn ...[Read More]

Science Communication – Brexit, Climate Change and the Bluedot Festival

Science Communication – Brexit, Climate Change and the Bluedot Festival

Earlier this summer journalists, broadcasters, writers and scientists gathered in Manchester, UK for the Third European Conference of Science Journalists (ECSJ) arranged by two prestigious organisations. Firstly, the Association of British Science Writers (ABSW) who provides support to those who write about science and technology in the UK through debates, events and awards. Secondly the European ...[Read More]

How does weather affect volcanoes?

How does weather affect volcanoes?

I was taking a plane trip home recently. To kill the time I got talking with the person sitting next to me and naturally one of their first questions was to ask me what I did for a living. To avoid a complicated discussion about the nuances of my research I summarised – ‘I am a volcanic meteorologist’. They were interested and wanted to know all about how volcanoes affect the weather, ...[Read More]

Atmospheric Modelling with Meso-NH

Atmospheric Modelling with Meso-NH

Twice a year in Toulouse Meteo-France runs a tutorial on Meso-NH – the non-hydrostatic mesoscale atmospheric model of the French research community. Last week I was fortunate enough to attend their autumn 2015 tutorial. But, what is this model and was the tutorial useful? Atmospheric models solve the governing equations for atmospheric motions. This allows us, for example, to forecast future ...[Read More]

Why should we care about a building’s energy consumption?

Why should we care about a building’s energy consumption?

From the 9th to the 11th of September the Solar Energy and Buildings Physics laboratory is hosting the CISBAT conference. This international meeting is seen as a leading platform for interdisciplinary dialog in the field of sustainability in the built environment. More than 250 scientists and people from the industry will be at EPFL in Lausanne to talk about topics from solar nanotechnologies to t ...[Read More]

Urban Climate

Urban Climate

The 9th International Conference on Urban Climate and the 12th Urban Environment Symposium are taking place this week in the “Pink City” Toulouse. With the 21st Conference of Parties (COP21) which will be held in December in Paris, the obvious focus topic for the urban climate conference is the mitigation and adaptation to climate change in urban environment. But, first of all, why should we even ...[Read More]

What is the biggest air pollution event in the modern era?

What is the biggest air pollution event in the modern era?

It’s hard to think of the scale of the biggest air pollution event in the modern era. Immediately my mind conjures up memories of black and white photographs of the Great London Smog of 1952. Then I start thinking bigger, how about the 1.2 billion vehicles world-wide on the road churning out nitrogen dioxide every single day? Well these are a drop in the ocean compared with bigger industrial pollu ...[Read More]

An unlikely choice between a gasoline or diesel car…

An unlikely choice between a gasoline or diesel car…

I have recently been confronted with the choice of buying a “new” car and this has proved to be a very tedious task with all the diversity of car that exists on the market today. However, one of my primary concerns was, of course, to find the least polluting car based on my usage (roughly 15000km/year). Cars (or I should say motor vehicles) pollution is one of the major sources of air pollution (p ...[Read More]
