Unprecedented glacier melting

Europian Geosciences Union released this news item with the above picture and entitled "Unprecedented glacier melting in the Andes blamed on climate change" along with this introduction:
Glaciers in the tropical Andes have been retreating at increasing rate since the 1970s, scientists write in the most comprehensive review to date of Andean glacier observations. The researchers blame the melting on rising temperatures as the region has warmed about 0.7°C over the past 50 years (1950-1994). This unprecedented retreat could affect water supply to Andean populations in the near future. These conclusions are published today in The Cryosphere, an Open Access journal of the European Geosciences Union (EGU).
O.K. for a lay person like me I have only one stupid question: If there is such thing as "rising temperatures" why are we still having the kind of cold winter we have.  Where is global warming?
