Ulrike Pfreundt, a researcher at the Swiss Federal Institute of Technology in Zurich, has used a 3D printer to create structures that can be used to build artificial coral reefs with more resilient corals.
Increasing water temperature disturbs the coexistence of corals and their symbiont algae. The corals expel the algae and in time in effect they starve to death. The process is known as coral bleaching.
And it is not only the corals that are at risk: the reefs are the breeding grounds for at least a quarter of oceanic fish species. Losing the coral reefs could have a devastating effect on the stability of marine ecosystems. In addition, coral reefs also provide natural protection for coastal regions, thereby also providing a direct service to humanity.
The scientist and her colleagues have used a 3D printer to produce artificial structures that coral larvae can settle on. Despite the higher temperature, not all corals die immediately. Pfreundt started with the assumption that some areas will continue to be suitable for coral reefs, for instance if there is a cooling current nearby.
The first utility-scale floating solar power plant was launched recently in Rechen, Germany. The 2300 solar panels afloat on the surface of a quarry pond are expected to produce 736 MWh of electricity per year.
In the fourth largest city of the state of Baden-Württemberg, urban development took a green direction a number of decades ago, which may serve as an example for other municipalities.
470 million years ago, Earth entered an ice age after an asteroid or minor planet broke up and created a gigantic dust cloud that obstructed sunlight. Scientist are now studying how humanity could create something similar to cool the planet’s climate.
The financial institutions that have officially committed to introducing the UN-backed principles of “responsible banking” to fight climate change control assets totalling $47 trillion.
Participants of the environmental initiative Plastic Cup have removed approximately 70 tonnes of waste from the River Tisza. To avoid further pollution of the river, an international cooperation will be necessary.
At the UN Climate Action Summit, the governments of sixty-six countries pledged to reach carbon neutrality by 2050.
Residents of the town of Frome in the county of Somerset, UK would like to grant legal personhood to the eponymous river.
On 15 October, the Budapest Water Summit 2019 will begin with the opening speech of President János Áder, the Chief Patron of the event. Invitation to three-day conference has been accepted by heads of state, ministers and high-ranking representatives of international organisations, financing and scientific institutes.
A new survey by CBS News shows that two-thirds of the Americans believe climate change is a crisis or a severe problem. 56 percent believe that immediate action is required to resolve the situation.
Here’s an inspiring and thought-provoking talk from a young climate activist who, at only 15, has become the iconic face of the fight against climate change.
