Mercury Rising

Yet more evidence of global warming:

Bears are supposed to slumber throughout the winter, slowing their body rhythms to a minimum and drawing on stored resources, because frozen weather makes food too scarce to find. The barely breathing creatures can lose up to 40 per cent of their body weight before warmer springtime weather rouses them back to life. But many of the 130 bears in Spain's northern cordillera - which have a slightly different genetic identity from bear populations elsewhere in the world - have remained active throughout recent winters, naturalists from Spain's Brown Bear Foundation (La Fundación Oso Pardo - FOP) said yesterday. The change is affecting female bears with young cubs, which now find there are enough nuts, acorns, chestnuts and berries on thebleak mountainsides to make winter food-gathering sorties "energetically worthwhile", scientists at the foundation, based in Santander, the Cantabrian capital, told El Pais newspaper. "If the winter is mild, the female bears find it is energetically worthwhile to make the effort to stay awake and hunt for food," said Guillermo Palomero, the FOP's president and the co-ordinator of a national plan for bear conservation. This changed behaviour, he said, was probably a result of milder winters. "The high Cantabrian peaks freeze all winter, but our teams of observers have been able to follow the perfect outlines of tracks from a group of bears," he said. [...] Other seasonal freaks * The osprey found in the lochs and glens of the Scottish Highlands in the summer months, usually migrate to west Africa to avoid the freeze. This winter, osprey have been spotted in Suffolk and Devon. Swallows, which also normally migrate to Africa for the winter have been also seen across England this winter. * The red admiral butterfly, which hibernates in winter, has been spotted in gardens this month, as has the common darter dragonfly, usually seen between mid-June and October, which has been seen in Cheshire, Norfolk and Hampshire. * The smew, a diving duck, flies west to the UK for winter from Russia and Scandinavia. This year, though, they have been mainly absent from the lakes and reservoirs between The Wash and the Severn. * Evergreen ivy and ox-eye daisies are still blooming and some oak trees, which are usually bare by November, were still in leaf on Christmas Day last year. * The buff-tailed bumblebee is usually first seen in spring. Worker bees die out by the first frost, while fertilised queen bees survive underground between March and September. This December, bees have been seen in Nottingham and York. * Primroses and daffodils are already flowering at the National Botanic Garden of Wales, in Carmarthenshire. 'Early Sensation' daffodils usually flower from January until February. Horticulturalists put it down to the warm weather. * Scientists in the Netherlands reported more than 240 wild plants flowering in the first 15 days of December, along with more than 200 cultivated species. Examples included cow parsley and sweet violets. Just two per cent of these plants normally flower in winter, while 27 per cent end their main flowering period in autumn and 56 per cent before October.
