What is happening to the weather? It's supposed to be deep midwinter in the northern hemisphere, but much of Central Europe is basking in spring temperatures. Meanwhile, fierce storms have caused havoc in Northern Europe from Ireland, across Scandinavia, through Belarus and on to Russia. Parts of Kazakhstan are overwhelmed with snow, and further afield, California is struggling against snow and flash floods. South Africa has flooding amid a drought -- and it's even been snowing in the parched deserts of the United Arab Emirates.
