How the blurring of the seasons is a harbinger of climate calamityBy Michael McCarthy, Environment Editor

Spring, which officially starts today, is starting to dissolve as a distinct season as climate change takes hold.
According to documented observations throughout 2007 and 2008, events in the natural world that used to be key spring indicators, from the blooming of flowers to the appearance of insects, are now increasingly happening in what used to be thought of as mid-winter, as Britain's temperatures steadily rise.
Although many people may see the changes as quaint or charming – butterflies certainly brighten up a January day – they are actually among the first concrete signs that the world is indeed set on a global warming course which is likely to prove disastrous if not checked.
In fact, the blurring of the seasons in Britain is now as serious a piece of evidence of climate change as the rapidly increasing melting of ice across the globe, in glaciers and in the land-based and marine ice sheets of the Arctic and the Antarctic.
The phenomenon shows that a whole range of organisms is already responding actively to the greatest environmental change in human history, in a way that people – and especially politicians – are not.
Last month, that shift produced its most remarkable image yet – a photograph, taken in Dorset, of a red admiral, an archetypal British summer butterfly, feeding on a snowdrop, an archetypal British winter flower.
Although that is not an event likely to cause alarm among the public, it was quite inconceivable until very recently. It is undeniable confirmation that a profound alteration in the environment, the consequences of which are likely to prove catastrophic, is already under way. ......(more)
