ASA says new satellite measurements indicate unprecedented recent Greenland ice sheet surface melt. The images above show the extent of surface melt over Greenland’s ice sheet over just a four day period - from July 8 (left) and July 12 (right). Measurements from three satellites showed that on July 8, about 40% of the ice sheet had undergone thawing at or near the surface. This melting dramatically accelerated to an estimated 97% of the ice sheet surface by July 12. On average in the summer, about half of the surface of Greenland's ice sheet naturally melts....

Chart shows the cost benefits through mitigation measures on the example of a landslide. It shows that only a certain effort in mitigation measures gain cost benefits. If to less measures are taken, the frequency and the impact of the events are still too high and a better optimum can be found. If too many measures are taken, the cost of mitigation and management will outnumber the gained benefits! ... Read more about Cost benefits through natural disaster mitigation?
The actual risk for a country to suffer in a long term from a natural disaster depends on the actual exposure but also on the vulnerability of a society (how can they cope and adapt to the event). Central America as well as big parts of Africa and Asia are at high risk to suffer in a long term from natural disasters. ... Read more about Natural Disaster Risk Index
