An uninhabited Pacific island has come top of the first comprehensive ocean health index, which compares all the world's coastal countries and scores them for how well the seas around them benefit both man and nature.

Tiny 4.5 sq km Jarvis island, halfway between Hawaii and the Cook Islands, was briefly mined for seabird fertiliser in the 19th century but both the waters around it and the island itself have been left more or less untouched since then, which accounts for its top score of 86 out of 100 compared with a global average of 60.

Extent of surface melt over Greenland’s ice sheet on July 8 (left) and July 12 (right). Measurements from three satellites showed that on July 8, about 40 percent of the ice sheet had undergone thawing at or near the surface. In just a few days, the melting had dramatically accelerated and an estimated 97 percent of the ice sheet surface had thawed by July 12. In the image, the areas classified as “probable melt” (light pink) correspond to those sites where at least one satellite detected surface melting. The areas classified as “melt” (dark pink) correspond to sites where two or three satellites detected surface melting. The satellites are measuring different physical properties at different scales and are passing over Greenland at different times. As a whole, they provide a picture of an extreme melt event about which scientists are very confident. Credit: Nicolo E. DiGirolamo, SSAI/NASA GSFC, and Jesse Allen, NASA Earth Observatory

The facts have changed, now we must change too. For the past 10 years an unlikely coalition of geologists, oil drillers, bankers, military strategists and environmentalists has been warning that peak oil – the decline of global supplies – is just around the corner. We had some strong reasons for doing so: production had slowed, the price had risen sharply, depletion was widespread and appeared to be escalating. The first of the great resource crunches seemed about to strike.
