Germany’s capital is becoming a sponge to stop flooding. It might seem counterintuitive to want to gather more water in order to stay dry, but that’s exactly the plan. Currently the city of Houston is suffering some of the worst flooding that its ever seen thanks largely to poor planning around water (like using highways to channel water). Berlin wants to avoid such trauma by working with water than against it.
The idea is simple and practical: do what nature does and store water in plants.
Ice cream is delicious and now you can eat a brand new flavour of it made of climate data. Well, it’s more like existing flavours put together to symbolize data about our climate and how it’s changing. Jonathon Keats is the brain behind the project and he’s mixing the ice cream together to raise awareness and to see if we can better understand the anthropocene if we use multiple senses.
The dessert will be served in Berlin during the STATE Festival for Open Science, Art & Society. If you’re in the area and looking for something sweet let us know if it tastes any good!
In his ice-cream model of the climate, Keats started with a detailed diagram of feedback loops made by University of Toronto computer scientist Steve Easterbrook. The model shows how each part of the system interrelates; as rising temperatures make ice melt, for example, the ground reflects less sunlight, which leads to even more warming.
In the sorbet, each part of the system is represented by a different ingredient that activates a different receptor in the gut. Sugar, which activates a receptor called TRPM-5, represents greenhouse gases; citric acids represent aerosols. Cinnamon is radiative balance, the relationship between the amount of energy reaching and leaving the Earth. In total, there are 12 ingredients
In cities all over the world housing people is an issue and some cities have it worse than others. In Berlin, where things weren’t awful they decided they waned to stop a downward trend that cropped up in the rental market. Renters were confronted with a market that was inhumane and the city took action.
Barely a month after the German capital introduced a new set of rules that limits rent increases within a given area, figures collected by ImmobilienScout24 show that the average cost of new Berlin rental contracts has dropped 3.1 percent within a month. This can’t be written off as an example of a general countrywide downward trend. In other German cities where such laws haven’t yet been introduced, rents have remained more or less static. This is good news for the legislators of Berlin’s Senate as their new law is doing exactly what they promised the electorate that it would.
The new law introduced on June 1st—called the mietpreisbremse or “rental price brake†in German—works like this. An overseeing body fixes a standard median rent per square meter for each city district, using figures based a biennial state census of rents. No new rental contract within the district is then permitted to charge over 10 percent more than this amount. This still means that price increases for new rentals are possible, but if they come, they happen far more slowly.
