World Weather Attribution is an academic collaboration studying extreme event attribution, calculations of the impact of climate change on extreme meteorological events such as heat waves, droughts, and storms. When an extreme event occurs, the project computes the likelihood that the occurrence, intensity, and duration of the event was due to climate change. The project specializes in producing reports rapidly, while news of the event is still fresh.

Technik ohne Grenzen e.V. (Technology without Borders, Germany) has one goal: improving living conditions in developing countries. This goal is pursued principally through the following three areas of activity: Coordinating on-site, tailored cooperative development work that makes the most effective use of the available resources. Delivering education and training that empower local people effect change themselves. Stimulating sustainable development, for example through microbusiness initiatives. Through these activities, we aim to put our technical expertise to meaningful use in the service of others. This is the guiding principle behind the foundation of our organisation, our motto being “as sophisticated as necessary, as simple as possible“. In the organisation’s name, the term “technology“ represents an invitation for all technical enthusiasts, as well as tradespeople, technicians, artisans and engineers, to participate in our work. Our organisation also places great importance on offering students the opportunity to make a difference through the application of technical and engineering skills to a variety of challenges in different locations and cultures. If these ideas inspire you, we would love to have you work with us!
