This particularly beautiful example of global warming comes from a Finnish photographer named Nayrde von Gobbels. Although you might not think a swan in ice could represent global warming, in fact it's a good example. Swans--which live on the ice at the edges, where it breaks up--leave the Helsinki area in late December or January, and traditionally do not return until mid-April, but now are returning in mid-March, reports Nayrde. I like this image not just because it's surprising, but also because it's a reminder that, despite all, this is a beautiful world, and we are fortunate to be part of it.
