From the lab to the field: How does climate science play out in reality? | John Vidal | Global development | guardian.co.uk
Peru is going through its coldest winter in 50 years and hundreds of people and thousands of animals have already died of hypothermia as temperatures have fallen to record -23C lows in the mountain villages. But while this year's cold has been put down to a periodic La Niña phenomenom, scientists here are convinced the bigger picture in the Andes is of progressive climate change.
Retreating glaciers, wild fluctuations of temperatures, unseasonal weather patterns, unpredictable frosts and extreme weather events are all consistent with climate change models.
