Record decline of ice sheets

For the first time scientists map elevation changes of Greenlandic and Antarctic glaciers. Researchers from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI), have for the first time extensively mapped Greenland’s and Antarctica’s ice sheets with the help of the ESA satellite CryoSat-2 and have thus been able to prove that the ice crusts of both regions momentarily decline at an unprecedented rate. In total the ice sheets are losing around 500 cubic kilometres of ice per year. This ice mass corresponds to a layer that is about 600 metres thick and would stretch out over the entire metropolitan area of Hamburg, Germany's second largest city. The maps and results of this study are published in The Cryosphere, an open access journal of the European Geosciences Union (EGU).

Human Contribution to Glacier Mass Loss on the Increase

By combining climate and glacier models, scientists headed by Ben Marzeion from the University of Innsbruck have found unambiguous evidence for anthropogenic glacier mass loss in recent decades. In a paper published in Science, the researchers report that about one quarter of the global glacier mass loss during the period of 1851 to 2010 is attributable to anthropogenic causes.

Antarctica could raise sea level faster than previously thought

Ice discharge from Antarctica could contribute up to 37 centimeters to the global sea level rise within this century, a new study shows. For the first time, an international team of scientists provide a comprehensive estimate on the full range of Antarctica’s potential contribution to global sea level rise based on physical computer simulations. Led by the Potsdam Institute for Climate Impact Research, the study combines a whole set of state-of-the-art climate models and observational data with various ice models. The results reproduce Antarctica’s recent contribution to sea level rise as observed by satellites in the last two decades and show that the ice continent could become the largest contributor to sea level rise much sooner than previously thought.

Ways of a new water policy 4/4

A vision for the future: if the Bundestag, i.e. German Parliament, passes a water conservation law that requires builders to install efficient fixtures, promotes private retrofits such as water-saving showers, toilets, washing machines and dishwashers and demands a water penny from large consumers, we will soon consume only half as much water as we do today. Every year 25,000 liters of water per capita would thus be saved, i.e. 250,000 liters in ten years. A family of four would save a million liters of water without sacrificing any comfort.

Water in trouble 3/4

Even in today’s water-rich Central Europe we are heading for a water shortage. Our water is being used, contaminated and wasted. Poison in water, chemical waste, fertilizers and air pollution threaten our most important means of survival.

So water is more than H2O 2/4

All founders of religions, philosophers and wisdom teachers from all periods and civilizations knew about that. The wonderful young man from Nazareth, an ecologist even 2,000 years ago, said, "Truly, truly, I say to you, unless one is born of water and the Spirit he cannot enter into the kingdom of God.” Responsible handling of water is religious service. And to those who wanted to follow him, ecologically-minded Jesus called out; “Be springs of living water.” He did not speak of impure or contaminated water. Parson Kneipp taught in the 19th century: “Aqua sanat – water heals!“
