Algacraft: a new biotech startup for algae research and applications

With several friends I am now a founding member of a new startup company: Algacraft LTD. Unicellular algae are a promising area for many future applications, from carbon capture to mitigate atmospheric greenhouse gas increases via the treatment of waste water and organic waste to the production of nutrients, food supplements and pharmaceutical substances. We develop a modular bioreactor for research that can grow many samples automatically in parallel under individual conditions. This saves time and effort. We will also provide this as a service to research institutes and commercial companies. The CEO ist Máté Ravasz, the trustees are (in alphabetical order) Daniel Budinov, Jiří Jirout, Stephan Matthiesen, Máté Ravasz and Matjaz Vidmar. Algacraft LTD is registered in Scotland private limited company under the number SC637776

1816, the Year without a Summer - Talk in Nuremberg, 15 Oct 2018

On Monday, 15 October 2018, I will give a talk (in German) on "Climate and history: 1816, the year without a summer" at the Naturhistorischen Gesellschaft (NHG). After the eruption of the volcano Tampora, Indonesia, in April 1815 the following year 1816 was a "year without summer" in Europe with cool, wet weather. This presentations discusses, what we know about the impact of the volcano on the world climate, and what this event meant for the people.

The presentation will be at 19:30 in the Katharinensaal of the City Library in Nuremberg (Am Katharinenkloster 5).

More information on the relation between climate and human history can be found (in German) on my website Klima und Geschichte.

Greenhouse gases and surface temperatures at EGU (17-22 Apr)

At the next General Assembly of the European Geoscientific Union (EGU) in Vienna (17-22 April 2016) I will again contribute to two sessions. I convene the session on greenhouse gas fluxes on local, regional and global scales using atmosphere, ocean and biosphere measurements.The EarthTemp session on measuring the surface temperatures of Earth, which I convened in previous years, is also in the programme again; this time Darren Ghent (Uni Leicester) is the main convener. The sessions are part of the work within the Greenhouse Gas Emissions and Feedback Programme and the EarthTemp Network.
