A bottle deposit hub on the outskirts of Oslo has had a stream of high-level international visitors. Can its success be replicated worldwide?

Tens of thousands of brightly coloured plastic drinks bottles tumble from the back of a truck on to a conveyor belt before disappearing slowly inside a warehouse on the outskirts of Oslo.

As a workman picks up a few Coke bottles that have escaped, Kjell Olav Maldum looks on. “It is a system that works,” he says as another truck rumbles past. “It could be used in the UK, I think lots of countries could learn from it.”

We’ll need to mitigate and adapt to global warming to avoid massive costs from sea level rise

Ocean waters are rising because of global warming. They are rising for two reasons. First, and perhaps most obvious, ice is melting. There is a tremendous amount of ice locked away in Greenland, Antarctica, and in glaciers. As the world warms, that ice melts and the liquid water flows to the oceans.

The other reason why water is rising is that warmer water is less dense – it expands. This expansion causes the surface of the water to rise.

Sandy, Bedfordshire: The house sparrows are busy caring for their young, but can still find time to mate dozens of times a day

Lolling in the shade under a hazel bush, I had become the inadvertent eavesdropper on a private conversation. Out of the canopy came a whispered “brrr” whirr of wings and then the soft sounds of sparrow seduction, a love song of tenderness that was scarcely imaginable from a bird known for its strident chirps.

Gentle, soothing, piteous peeps drifted down, an intimate dialogue that was both charming and disarming. I caught a glimpse through the sparrows’ bower and saw the female, mouth agape, wings a-flutter. The male rode her for a second or two only. House sparrows may mate up to 40 times a day, but it’s always a quickie.
